RFC 1251                       Who's Who                     August 1991


1. Introduction

  There are thousands of networks in the internet.  There are tens of
  thousands of host machines.  There are hundreds of thousands of
  users.  It takes a great deal of effort to manage the resources and
  protocols which make the Internet possible.  Sites may have people
  who get paid to manage their hardware and software.  But the
  infrastructure of the Internet is managed by volunteers who spend
  considerable portions of their valued time to keep the people
  connected.

  Hundreds of people attend the three IETF meetings each year.  They
  represent the government, the military, research institutions,
  educational institutions, and vendors from all over the world.  Most
  of them are volunteers; people who attend the meetings to learn and
  to contribute what they know.  There are a few very special people
  who deserve special notice.  These are the people who sit on the IAB,
  IESG, and IRSG.  Not only do they spend time at the meetings, but
  they spend additional time to organize them.  They are the IETF's
  interface to other standards bodies and to the funding institutions.
  Without them, the IETF, indeed the whole Internet, would not be
  possible.

2. Acknowledgements

  In addition to the people who took the time to write their
  biographies so that I could compile them into this FYI RFC, I would
  like to give special thanks to Joyce K. Reynolds (whose biography is
  in here) for her help in creating the biography request message and
  for being such a good sounding board for me.

3. Request for Biographies

  In mid-February, I sent the following message to the members of the
  IAB, IESG and IRSG.  It is their responses to this message that I
  have compiled in this FYI RFC.

     The ARPANET is 20 years old.  The next meeting of the IETF in St.
     Louis this coming March will be the 20th plenary.  It is a good
     time to credit the people who help make the Internet possible.  I
     am sending this request to the current members of the IAB, the
     IRSG, and the IESG.  At some future time, I would like to expand
     the number of people to be included.  For now, however, I am
     limiting inclusion to members of the groups listed above.

     I would like to ask you to submit to me your biography.  I intend
     to compile the bios submitted into an FYI RFC to be published
     before the next IETF meeting.  In order to maintain some

     consistency, I would like to have the bios contain three
     paragraphs.  The first paragraph should contain your bio, second
     should be your school affiliation & other interests, and the third
     should contain your opinion of how the Internet has grown.  Of
     course, if there is anything else you would like to say, please
     feel free.  The object is to let the very large user community
     know about the people who give them what they have.

4. Biographies

  The biographies are in alphabetical order.  The contents have not
  been edited; only the formating has been changed.

     4.1  Robert Braden, IAB Executive Director

          Bob Braden joined the networking research group at ISI in
          1986.  Since thenf, he has been supported by NSF for research
          concerning NSFnet, and by DARPA for protocol research.  Tasks
          have included designing the statspy program for collecting
          NSFnet statistics, editing the Host Requirements RFCs, and
          coordinating the DARPA Research Testbed network DARTnet.  His
          research interests generally include end-to-end protocols,
          especially in the transport and network (Internet) layers.

          Braden came to ISI from UCLA, where he had worked 16 of the
          preceding 18 years for the campus computing center.  There he
          had technical responsibility for attaching the first
          supercomputer (IBM 360/91) to the ARPAnet, beginning in 1970.
          Braden was active in the ARPAnet Network Working Group,
          contributing to the design of the FTP protocol in particular.
          In 1975, he began to receive direct DARPA funding for
          installing the 360/91 as a "tool-bearing host" in the
          National Software Works.  In 1978, he became a member of the
          TCP Internet Working Group and began developing a TCP/IP
          implementation for the IBM system.  As a result, UCLA's
          360/91 was one of the ARPAnet host systems that replaced NCP
          by TCP/IP in the big changeover of January 1983.  The UCLA
          package of ARPAnet host software, including Braden's TCP/IP
          code, was distributed to other OS/MVS sites and was later
          sold commercially.

          Braden spent 1981-1982 in the Computer Science Department of
          University College London.  At that time, he wrote the first
          Telnet/XXX relay system connecting the Internet with the UK
          academic X.25 network.  In 1981, Braden was invited to join
          the ICCB, an organization that became the IAB, and has been
          an IAB member ever since.  When IAB task forces were formed
          in 1986, he created and still chairs the End-to-End Task

          Force (now Research Group).

          Braden has been in the computer field for 40 years this year.
          Prior to UCLA, he worked at Stanford and at Carnegie Tech.
          He has taught programming and operating systems courses at
          Carnegie Tech, Stanford, and UCLA.  He received a Bachelor of
          Engineering Physics from Cornell in 1957, and an MS in
          Physics from Stanford in 1962.

          ------------

          Regardless of the ancient Chinese curse, living through
          interesting times is not always bad.

          For me,  participation in the development of the ARPAnet and
          the Internet protocols has been very exciting.  One important
          reason it worked, I believe, is that there were a lot of very
          bright people all working more or less in the same direction,
          led by some very wise people in the funding agency.  The
          result was to create a community of network researchers who
          believed strongly that collaboration is more powerful than
          competition among researchers.  I don't think any other model
          would have gotten us where we are today.  This world view
          persists in the IAB, and is reflected in the informal
          structure of the IAB, IETF, and IRTF.

          Nevertheless, with growth and success (plus subtle policy
          shifts in Washington), the prevailing mode may be shifting
          towards competition, both commercial and academic.  To
          develop protocols in a commercially competitive world, you
          need elaborate committee structures and rules.  The action
          then shifts to the large companies, away from small companies
          and universities.  In an academically competitive world, you
          don't develop any (useful) protocols; you get 6 different
          protocols for the same objective, each with its research
          paper (which is the "real" output).  This results in
          efficient production of research papers, but it may not
          result in the kind of intellectual consensus necessary to
          create good and useful communication protocols.

          Being a member of the IAB is sometimes very frustrating.  For
          some years now we have been painfully aware of the scaling
          problems of the Internet, and since 1982 have lived through a
          series of mini-disasters as various limits have been
          exceeded.  We have been saying that "getting big" is probably
          a more urgent (and perhaps more difficult) research problem
          than "getting fast", but it seems difficult to persuade
          people of the importance of launching the kind of research



Malkin                                                          [Page 4]

RFC 1251                       Who's Who                     August 1991


          program we think is necessary to learn how to deal with
          Internet growth.

          It is very hard to figure out when the exponential growth is
          likely to stop, or when, if ever, the fundamental
          architectural model of the Internet will be so out of kilter
          with reality that it will cease be useful.  Ask me again in
          ten years.

     4.2  Hans-Werner Braun, IAB Member

          Hans-Werner Braun joined the San Diego Supercomputer Center
          as a Principal Scientist in January 1991. In his initial
          major responsibility as Co-Principal Investigator of, and
          Executive Committee member on the CASA gigabit network
          research project he is working on networking efforts beyond
          the problems of todays computer networking infrastructure.
          Between April 1983 and January 1991 he worked at the
          University of Michigan and focused on operational
          infrastructure for the Merit Computer Network and the
          University of Michigan's Information Technology Division.
          Starting out with the networking infrastructure within the
          State of Michigan he started to investigate into TCP/IP
          protocols and became very involved in the early stages of the
          NSFNET networking efforts.  He was Principal Investigator on
          the NSFNET backbone project since the NSFNET award went to
          Merit in November 1987 and managed Merit's Internet
          Engineering group. Between April 1978 and April 1983 Hans-
          Werner Braun worked at the Regional Computing Center of the
          University of Cologne in West Germany on network engineering
          responsibilities for the regional and local network.

          In March 1978 Hans-Werner Braun graduated in West Germany and
          holds a Diploma in Engineering with a major in Information
          Processing. He is a member of the Association of Computing
          Machinery (ACM) and its Special Interest Group on
          Communications, the Institute of Electrical and Electronical
          Engineers (IEEE) as well as the IEEE Computer Society and the
          IEEE Communications Society and the American Association for
          the Advancement of Science. He was a member of the National
          Science Foundation's Network Program Advisory Group (NPAG)
          and in particular its Technical Committee (NPAG-TC) between
          November 1986 and late 1987, at which time the NPAG got
          resolved. He also chaired the Technical Committee of the
          National Science Foundation's Network Program Advisory Group
          (NPAG-TC) starting in February 1987. Prior to the
          organizational change of the JvNCnet he participated in the
          JvNCnet Network Technical Advisory Committee (NTAC) of the

RFC 1251                       Who's Who                     August 1991


          John von Neumann National Supercomputer Center. While working
          as Principal Investigator on the NSFNET project at Merit, he
          chaired the NSFNET Network Technical Committee, created to
          aid Merit with the NSFNET project.  Hans-Werner Braun is a
          member of the Engineering Planning Group of the Federal
          Networking Council (FEPG) since its beginnings in early 1989,
          a member of the Internet Activities Board (IAB), the Internet
          Engineering Task Force. He had participated in an earlier,
          informal, version of the Internet Engineering Steering Group
          and the then existing Internet Architecture Task Force. While
          at Merit, Hans-Werner Braun was also Principal Investigator
          on NSF projects for the "Implementation and Management of
          Improved Connectivity Between NSFNET and CA*net" and for
          "Coordinating Routing for the NSFNET," the latter at the time
          of the old 56kbps NSFNET backbone network that he was quite
          intimately involved with.

          ------------

          The growth of the Internet can be measured in many ways and I
          can only try to find some examples.

          o Network number counts

          There were days where being "connected to net 10" was the
          Greatest Thing Ever.  A time where the Internet just
          consisted of a few networks centered around the ARPAnet and
          where growing above 100 network numbers seemed excessive.
          Todays number of networks in the global infrastructure
          exceeds 2000 connected networks, and many more if isolated
          network islands get included.

          o Traffic growth

          The Internet has undergone a dramatic increase in traffic
          over the last few years. The NSFNET backbone can be used as
          an example here, where in August 1988 about 194 million
          packets got injected into the network, which had increased to
          about 396 million packets per month by the end of the year,
          to reach about 4.8 billion packets in December 1990. January
          1991 yielded close to 5.9 billion packets as sent into the
          NSFNET backbone.

          o Internet Engineering Task Force participation

          The early IETF, after it spun off the old GADS, included
          about 20 or so people. I remember a meeting a few people had
          with Mike Corrigan several years ago. Mike then chaired the



Malkin                                                          [Page 6]

RFC 1251                       Who's Who                     August 1991


          IETF before Phill Gross became chair and the discussion was
          had about permitting the "NSFNET crowd" to join the IETF.
          Mike finally agreed and the IETF started to explode in size,
          now including many working groups and several hundred
          members, including vendors and phone companies.

          o International infrastructure

          At some point of time the Internet was centric around the US
          with very little international connectivity. The
          international connectivity was for network research purposes,
          just like the US domestic component at that point of time.
          Today's Internet stretches to so many countries that it can
          be considered close to global in scope, in particular as more
          and more international connections to, as well as Internet
          infrastructure within, other countries are happening.

          o References in trade journals

          Many trade journals just a year or two ago had close to no
          mention of the Internet. Today references to the Internet
          appear in many journals and press releases from a variety of
          places.

          o Articles in professional papers

          Publications like ACM SIGCOMM show increased interest for
          Internet related professional papers, compared to a few years
          ago. Also the publication rate of the Request For Comments
          (RFC) series is quite impressive.

          o Congressional and Senatorial visibility

          A few years ago the Internet was "just a research project."
          Today's dramatically increased visibility in result of the
          Internet success allows Congress as well as Senators to play
          lead roles in pushing the National Research and Education
          Network (NREN) agenda forward, which is also fostered by the
          executive branch. In the context of the US federal government
          the real credit should go to DARPA, though, for starting to
          prototype advanced networking, leading to the Internet about
          twenty years ago and over time opening it up more and more to
          the science and research community until more operational
          efforts were able to move the network to a real
          infrastructure in support of science, research and education
          at large. This really allowed NSF to make NSFNET happen.





Malkin                                                          [Page 7]

RFC 1251                       Who's Who                     August 1991


          o Funding

          The Internet funding initially consisted of DARPA efforts.
          Agencies like NSF, NASA, DOE and others started to make major
          contributions later. Industrial participation helped moving
          the network forward as well. Very major investments have been
          made by campuses and research institutions to create local
          infrastructure. Operational infrastructure comes at a high
          cost, especially if ubiquity, robustness and high performance
          are required.

          o Research and continued development

          The Internet has matured from a network research oriented
          environment to an operational infrastructure supporting
          research, science and education at large. However, even
          though for many people the Internet is an environment
          supporting their day-to-day work, the Internet at its current
          level of technology is supported by a culture of people that
          cooperates in a largely non-competitive environment. Many
          times already the size of the routing tables or the amount of
          traffic or the insufficiency of routing exchange protocols,
          just to name examples, have broken connectivity with many
          people being interrupted in their day-to-day work. Global
          Internet management and problem resolution further hamper
          fast recovery from certain incidents. It is unproven that the
          current technology will survive in a competitive but
          unregulated environment, with uncoordinated routing policies
          and global network management being just two of the major
          issues here.  Furthermore, while frequently comments are
          being made where the publicly available monthly increases in
          traffic figures would not justify moving to T3 or even
          gigabit per second networks, it should be pointed out that
          monthly figures are very macroscopic views. Much of the
          Internet traffic is very bursty and we have frequently seen
          an onslaught of traffic towards backbone nodes if one looks
          at it over fairly short intervals of time. For example, for
          specific applications that, perhaps in real-time, require an
          occasional exchange of massive amounts of data. It is
          important that we are prepared for more widespread use of
          such applications, once people are able to use things more
          sophisticated than Telnet, FTP and SMTP. I am not sure
          whether the amount of research and development efforts on the
          Internet has increased over time, less even kept pace with
          the general Internet growth (by whatever definition). I do
          not believe that the Internet is a finished product at this
          point of time and there is a lot of room for further
          evolution.

     4.3  Ross Callon, IETF OSI Integration Area Co-director

          Ross Callon is a member of the Distributed Systems
          Architecture staff at Digital Equipment Corporation in
          Littleton Massachusetts.  He is working on issues related to
          OSI -- TCP/IP interoperation and introduction of OSI in the
          Internet. He is the primary author of the Integrated IS-IS
          protocol (RFC1195), and has also worked on guidelines for
          allocation of NSAP addresses in the Internet.  Mr Callon is
          the co-area director for the OSI area of the IETF, chair of
          the IETF IS-IS working group, and co-chair of the IETF OSI-
          General working group.

          Previous to joining DEC, Mr Callon was with Bolt Beranek and
          Newman, where he worked on OSI Standards, Network Management,
          Routing Protocols and other router-related issues.

          Mr Callon received a Bachelor of Science degree in
          Mathematics from the Massachusetts Institute of Technology,
          and a Master of Science degree in Operations Research from
          Stanford University.

          ------------

          During eleven years of involvement with the Internet
          community it has been exciting to see the explosive growth in
          data communications from a relatively obscure technology to a
          technology in widespread everyday use. For the future, I am
          interested in transition to a world-wide multi-protocol
          Internet. This requires scaling to several orders of
          magnitude larger than the current Internet, and also requires
          a greater emphasis on reliability and ease of use.

          ------------

          The Internet started as a focused DARPA research effort to
          develop a capability to link computers across multiple,
          internally diverse packet networks. The successful evolution
          of this technology through 4 versions, demonstration on
          ARPANET, mobile packet radio nets, the Atlantic SATNET and
          at-sea MATNET provided the basis for formal mandating of the
          TCP/IP protocols for use on ARPANET and other DoD systems in
          1983. By the mid-1980's, a market had been established for
          software and hardware supporting these protocols, largely
          triggered by the Ethernet and other LAN phenomena, coupled

RFC 1251                       Who's Who                     August 1991


          with the rapid proliferation of UNIX-based systems which
          incorporated the TCP/IP protocols as part of the standard
          release package.  Concurrent with the development of a market
          and rapid increase in vendor interest, government agencies in
          addition to DoD began applying the technology to their needs,
          culminating in the formation of the Federal Research Internet
          Coordinating Committee which has now evolved into the Federal
          Networking Council, in the U.S. At the same time, similar
          rapid growth of TCP/IP technology application is occurring
          outside the US in Europe, the Middle East, the Pacific Rim,
          Eurasia, Australia, South and Central America and, to a
          limited extent, Africa.  The internationalization of the
          Internet has spawned new organizational foci such as the
          Coordinating Committee for International Research Networking
          (CCIRN) and heightened interest in commercial provision of IP
          services (e.g. in Finland, the U.S., the U.K. and elsewhere).

          The Internet has also become the basis for a proposed
          National Research and Education Network (NREN) in the U.S.
          It's electronic messaging system has been linked to the major
          U.S.  commercial email carriers and to other major private
          electronic mail services such as Bitnet (in the US, EARN in
          Europe) as well as UUNET (in the U.S.) and EUNET (in Europe).
          The Bitnet and UUCP-based systems are international in scope
          and complement the Internet system in terms of email
          connectivity.

          With the introduction of OSI capability (in the form of CLNP)
          into important parts of the Internet (such as the NSFNET
          backbone and selected intermediate level networks), a path
          has been opened to support the use of multiple protocol
          suites in the Internet. Many of the vendor routers/gateways
          support TCP/IP, OSI and a variety of vendor-specific
          protocols in a common network environment.

          In the U.S., regional Bell Operating Company carriers are
          planning the introduction of Switched Multimegabit Data
          Services and Frame Relay services which can support TCP/IP
          and other Internet protocols. On the research side, DARPA and
          the NSF are supporting a major initiative in gigabit speed
          networking, towards which the NREN is aimed.

          The Internet is a grand collaboration of over 5000 networks
          involving millions of users, hundreds of thousands of hosts
          and dozens of countries around the world. It may well do for
          computers what the telephone system has done for people:
          provided a means for international interchange of information
          which is blind to nationality, proprietary interests, and

     4.5  Noel Chiappa, IETF Internet Services Area Director

          Noel Chiappa is currently an independent inventor working in
          the area of computer networks and system software. His
          principal occupation, however, is his service as the Area
          Director for Internet Services of the Steering Group of the
          Internet Engineering Task Force.

          His primary current research interest is in the area of
          routing and addressing architectures for very large scale
          (globally ubiquitous and larger) internetworks, but he is
          generally interested in the problems of the packet layer of
          internetworking; i.e. everything involved in getting traffic

          from one host to another anywhere in the internetwork.  As a
          with many novel features intended for use in large
          programming projects with many source and header files.

          He has been a member of the TCP/IP Working Group and its
          successors (up to the IETF) since 1977. He was a member of
          the Research Staff at the Massachusetts Institute of
          Technology from 1977-1982 and 1984-1986. While at MIT he
          worked on packet switching and local area networks, and was
          responsible for the conception of the multi-protocol backbone
          and the multi-protocol router.  After leaving MIT he worked
          with a number of companies, including Proteon, to bring
          networking products based on work done at MIT to the public.
          He attended Phillips Andover Academy and MIT.  He was born
          and bred in Bermuda.

          His outside interests include study and collection of antique
          racing cars (principally Lotuses), reading (particularly
          political and military history and biographies), landscape
          gardening (particularly Japanese), and study of Oriental rugs
          (particularly Turkoman tribal rugs) and Oriental antiques
          (particularly Japanese lacquerware and Chinese archaic
          jades).

          the development of software for distributed resource
          management (operating-system embedded RPC), distributed
          database management, X.25-based local and wide- area
          networks, and OSI-based transport, internetwork, and routing
          functions for DG's open-system products.  In 1987 he formed
          the Distributed Systems Architecture group, and was
          responsible for the development of DG's Distributed
          Application Architecture (DAA) and for the specification of
          the directory and management services of DAA.  He moved to
          Bolt, Beranek & Newman in 1990 as the Chief Network Architect
          in BBN's Communications Division, where he serves as a
          consultant to the Systems Architecture group and the
          coordinator for BBN's open system standards activities.  He
          is the chairman of ANSI-accredited task group X3S3.3,
          responsible for Network and Transport layer standards, since
          1982;  vice-chairman of the ACM Special Interest Group on
          Data Communications (SIGCOMM) since 1985;  and a member of
          the Internet Activities Board (IAB) since 1989.  He lives
          with his wife and two young daughters in Hopkinton,
          Massachusetts.

          ------------

          I started out in 1977 working with X.25 networks, and began
          working on OSI in 1979 - first the architecture (the OSI
          Reference Model), and then the transport and internetwork
          protocol specifications.  It didn't take long to recognize
          the basic irony of OSI standards development:  there we were,
          solemnly anointing international standards for networking,
          and every time we needed to send electronic mail or exchange
          files, we were using the TCP/IP-based Internet!  I've been
          looking for ways to overcome this anomaly ever since;  to
          inject as much of the proven TCP/IP technology into OSI as
          possible, and to introduce OSI into an ever more pervasive
          and worldwide Internet.  It is, to say the least, a
          challenge!

     4.7  Dr. David Clark, IAB Member, IRTF Chairman

          David Clark works at the M.I.T. Laboratory for Computer
          Science, where he is a Senior Research Scientist. His current
          research involves protocols for high speed and very large
          networks, in particular the problems of routing and flow and
          congestion control. He is also working on integration of
          video into packet networks. Prior to this effort, he
          developed a new implementation approach for network software,
          and an operating system (Swift) to demonstrate this concept.
          Earlier projects include the token ring LAN and the Multics

          operating system. He joined the TCP development effort in
          1975, and chaired the IAB from 1981 to 1990. He has a
          continuing interest in protocol performance. He is also
          active in the area of computer and communications security.

          David Clark received his BSEE from Swarthmore College in
          1966, and his MS and PhD from MIT, the latter in 1973. He has
          worked at MIT since then.

          ------------

          It is not proper to think of networks as connecting
          computers. Rather, they connect people using computers to
          mediate. The great success of the internet is not technical,
          but in human impact. Electronic mail may not be a wonderful
          advance in Computer Science, but it is a whole new way for
          people to communicate. The continued growth of the Internet
          is a technical challenge to all of us, but we must never
          loose sight of where we came from, the great change we have
          worked on the larger computer community, and the great
          potential we have for future change.

     4.8  Dr. Stephen Crocker, IETF Security Area Director

          Currently I'm vice president of Trusted Information Systems,
          Inc.  which I joined in late 1986.  I set up TIS' Los Angeles
          office and ran it until summer 1989 when I moved to the home
          office in Maryland.  At TIS my primary concerns are program
          verification research and application, integration of
          cryptography with trusted systems, network security, and new
          applications for networks and trusted systems.

          I was at the Aerospace Corporation from 1981-86 as Director
          of the Information Sciences Research Office which later
          became the Computer Science Laboratory.  The research program
          at Aerospace included networks, program verification,
          artificial intelligence, applications of expert systems, and
          parallel processing.

          From 1974-81 I was a researcher at USC's Information Sciences
          Institute, where I focused primarily on program verification.
          From 1971-74 I was a program manager at DARPA/IPTO (now
          ISTO).  I was responsible for the research programs in
          artificial intelligence, automatic programming, speech
          understanding, and some parts of the network research.  I
          also initiated an ambitious but somewhat ill-fated venture
          called the National Software Works.




Malkin                                                         [Page 14]

RFC 1251                       Who's Who                     August 1991


          From 1968-71 I was a graduate student in the UCLA Computer
          Science Department.  While there I initiated the Network
          Working Group, arguably the forerunner of the IETF and many
          related groups around the world, and helped define the
          original suite of protocols for the Arpanet.  I also
          initiated the Request for Comments (RFC) series.  A short
          description of the events of that era are contained in RFC
          1000.

          I was a graduate student in the MIT AI Lab for a year and a
          half in 1967-68, and I was an undergraduate at UCLA for a
          long time before that.

          ------------

          I've watched the Internet grow from its beginning.  At UCLA
          we had the privilege of being node 1 of the Arpanet.  In
          those days, several of us dreamed of very high quality
          intercomputer connections and very rich protocols to knit the
          computers together.  Some of the those concepts are stilled
          discussed and anticipated today under the names remote
          visualization, distributed file systems, etc.  On the other
          hand, I would never have imagined that 20 years later we'd
          have such a plethora of different network technologies.  Even
          more astonishing is the enormous number of independently
          managed but nonetheless interconnected networks that make up
          the current network.  And somewhat beyond comprehension is
          that it seems to work.

          How will the Internet evolve?  I expect to see substantial
          developments in the following dimensions.

          o Regularization, internationalization and commercialization

          Standards will become even more important than they are now.
          Implementations of protocols and related mechanisms will
          become more standard and robust.  The relationship between
          the TCP/IP stack and the OSI stack will be resolved, with
          either both co-existing, OSI winning out, or some
          intermediate convergence emerging.

          The Internet will become a less U.S.-centric and more
          international operation.  Much of the Internet will be
          operated by commercial concerns on a a profit-making basis,
          thereby opening up the Internet to unrestricted use.  The
          telephone companies, including both the local exchange
          carriers and the interexchange carriers, will start providing
          some of the protocol stack other than the point-to-point

RFC 1251                       Who's Who                     August 1991


          lines.

          o Higher and lower bandwidths; great proliferation

          I expect to see T1 connections become the norm for the types
          of institutions that are now on the Internet.  Higher speeds,
          including speeds up to a gigabit will become available.  At
          the same time, I expect to see a vast expansion of the
          Internet, reaching into a significant fraction of the schools
          and businesses in this country and elsewhere in the world.
          Many of these institutions will be connected at 9600 bits/sec
          or slower.

          o More applications

          E-mail dominates the Internet, and it's likely to remain the
          dominant use of the Internet in the future.  Nonetheless, I
          expect to see an exciting array of other applications which
          become heavily used and cause a change in the perception of
          the Internet as primarily a "mail system."  Important
          databases will become available on the Internet, and
          applications dependent on those databases will flourish.  New
          techniques and tools for collaboration over a network will
          emerge.  These will include various forms of conferencing and
          cooperative multi-media document development.

          o Security

          Security will tighten up on the Internet, but not without
          some (more) pain.  Host operating systems will be built,
          configured, distributed and operated under much tighter
          constraints than they have been.  Firewalls will abound.
          Encryption will be added to links, routers and various
          protocol layers.  All of this will decrease the utility of
          the Internet in the short run, but lay the groundwork for
          broader use eventually.  New protocols will emerge which
          incorporate sound protection but also provide efficient and
          flexible access control and resource sharing.  These will
          provide the basis for the kind of close knit applications
          that motivated the original thinking behind the Arpanet.

          where much of his work focused on network management. He has
          also worked at Data General's Research Triangle Park facility
          on a variety of communications protocols.

          He holds the B.A. from Haverford College and masters degrees
          in Computer Science and English from Duke University.

          ------------

          The growth of the internet over the years has taken it from
          lower speeds to higher speeds, from limited geographical
          extent to global presence, from research apparatus to an
          essential social and commercial infrastructure, from
          experimentation among a few networking sophisticates to daily
          use by thousands in all walks of life. This latter sort of
          growth is almost certainly the most valuable.

          Davis where he currently works as Data Communications
          Manager.  He also represents UC Davis as a founding member in
          the Bay Area Regional Research Network (BARRNet).  He formed
          and now chairs the California Internet Federation, a forum
          for coordinating educational and research networks in
          California.  In addition he is Area Director for Applications
          in the Internet Engineering Task Force and a member of the
          Internet Engineering Steering Group.

          As Data Communications Manager at UC Davis, Russ is
          responsible for all aspects of campus networking including
          network design, implementation, and operation.  UC Davis has
          also been instrumental in the development of new network
          protocols and their prototype implementations, in particular,
          the Point-to- Point Protocol (PPP).  UC Davis has been very
          active in the use of networking for students from
          kindergarten through community colleges and has had the Davis
          High School on the Internet since 1989.  In conjunction with
          the City of Davis, UC Davis is planning a community network
          using ISDN to bring networking into the residences in Davis
          for university network connection, high school and library
          resource access, telecommuting, and electronic democracy.

          ------------

          I have seen the rapid growth of the Internet into a worldwide
          utility, but believe that it is lacking in the types of

          applications that could make use of its full potential.  I
          believes that it is time to look at the network from the
          users side and consider the functionality that they desire.
          New applications for information storage and retrieval,
          personal and group communications, and coordinated computer
          resources are needed.  I think, "Networks aren't just for

          Christian HUITEMA has conducted for several years research in
          network protocols and network applications. He is now at
          INRIA in Sophia-Antipolis, where he leads the research
          project "RODEO", whose objective is the definition and the
          experimentation of communication protocols for very high
          speed networks, at one Gbit/s or more. This includes the
          study of high speed transmission control protocols, of their
          parameterization and of their insertion in the operating
          systems, and the study of the synchronization functions and
          of the management of data transparency between heterogeneous
          systems. The work is conducted in cooperation with industrial
          partners and takes into account the evolution of the
          communication standards.  Previously, he took part to the
          NADIR project, investigating computer usage of
          telecommunication satellites, and to OSI developments in the
          GIPSI project for the SM90 work station, including one of the
          earliest X.400 systems, and to the ESPRIT project THORN,
          which is provide one of the first X.500 conformant directory
          system.

          Christian Huitema graduated from the Ecole Polytechnique in
          Paris in 1975, and passed his doctorate in the University of
          Paris VI in 1985.

          ------------

          The various projects which followed the "Cyclades" network in
          France were following closely the developments of the Arpanet
          and then the Internet. However, the first linkage was
          established in the early 80's through mail connections. I was
          directly involved in the setting up of the first direct TCP-
          IP connection between France and the Internet (actually,
          NSFNET) which was first experimented in 1987, and became
          operational in 1988. This interconnection, together with
          parallel actions in the Nordic countries of Europe, at CERN
          and through the EUNET association, was certainly influential
          in the development TCP/IP internetting in Europe. The rapid
          growth of the Internet here is indicative both of the

          Corporation, where he currently manages the
          Telecommunications and Networks Architecture and Advanced
          Development group.  For the past fifteen years his group has

          Digital's DECnet computer networking products.  His group has
          played a leading role in local area network standardization,
          including Ethernet, FDDI, and transparent bridged LANs.  His
          group has also played a leading role in standardizing the OSI
          network and transport layers.  Most recently, they have
          completed the architecture for the next phase of DECnet which
          is based on OSI while providing backward compatibility with
          DECnet Phase IV.  Prior to his role in network architecture
          he was responsible for setting the direction of Digital's
          PDP-11 communications products.  In addition to working at
          Digital, he worked at Autex, Inc. where was a designer of a
          transaction processing system for securities trading and at
          the Smithsonian Astrophysical Observatory were he developed
          an early remote batch system.

          Mr. Lauck received his BA degree from Harvard in 1965.  He
          has worked in a number of areas related to data
          communication, ranging from design of physical links for
          local area networks to applications for distributed
          processing.  His current interests include high speed local
          and wide area networks, multiprotocol networking, network
          security, and distributed processing. He was a member of the
          Committee on Computer-Computer Communications Protocols of
          the National Research Council which did a comparison of the
          TCP and TP4 transport protocols for DOD and NBS.  He was also
          a member of the National Science Foundation Network Technical
          Advisory Board. In December of 1984, he was recognized by
          Science Digest magazine as one of America's 100 brightest
          young scientists for his work on computer networking.

          ------------

          In 1978 Vint Cerf came to Digital to give a lecture on TCP
          and IP, just prior to the big blizzard.  I was pleased to see
          that TCP/IP shared the same connectionless philosophy of
          networking as did DECnet.  Some years later, Digital decided
          that future phases of DECnet would be based on standards.
          Since Digital was a multinational company, the standards
          would need to be international.  Unfortunately, in 1980 ISO
          rejected TCP and IP on national political grounds.  When it
          looked like the emerging OSI standards were going to be
          limited to purely connection- oriented networking, I was very
          concerned and began efforts to standardize connectionless
          networking in OSI.  As it turned out, TCP/IP retained its
          initial lead over OSI, moving internationally as the Internet
          expanded, thereby becoming an international protocol suite
          and meeting my original needs.  I hope that the Internet can
          evolve into a multiprotocol structure that can accommodate

          of religious fervor.  It will be exciting to solve problems
          like network scale and security, especially in the context of
          a network which must serve users while it evolves.

          My first exposure to the internet (actually Arpanet) was in
          1977 when, as a DARPA contractor, I was provided access.  At
          that point, the Arpanet was primarily used to support DARPA

          and related activities, and was confined to a relatively
          small set of users and sites.  The Internet technology was
          just in the process of being developed and demonstrated.  In
          fact, my DARPA contract was in relation to the Packet Radio
          Network, and the primary motivation for the Internet
          technology was to connect the mobile Packet Radio Network to
          the long-haul Arpanet.  Now, only 13 years later, things have
          changed radically.  The Internet has grown by several orders
          of magnitude in size and connects a much wider community,
          including academic, commercial, and government.  It has
          spread well beyond the USA to include many organizations
          throughout the world.  It has grown beyond the experimental
          network to provide operational service.  Its influence is
          seen throughout the computer communications community.

     4.15 Daniel C. Lynch, IAB Member

          Daniel C. Lynch, 49, is president and founder of Interop,
          Inc.  (formerly named Advanced Computing Environments) in
          Mountain View, California since 1985.  A member of ACM, IEEE
          and the IAB, he is active in computer networking with a
          primary focus in promoting the understanding of network
          operational behavior.  The annual INTEROP (conference and
          exhibition is the major vehicle for his efforts.

          As the director of Information Processing Division for the
          Information Sciences Institute in Marina del Rey (USC-ISI)
          Lynch led the Arpanet team that made the transition from the
          original NCP protocols to the current TCP/IP based protocols.
          Lynch directed this effort with 75 people from 1980 until
          1983.

          He was Director of Computing Facilities at SRI International
          in the late 70's serving the computing needs of over 3,000
          employees.  He formerly served as manager of the computing
          laboratory for the Artificial Intelligence Center at SRI
          which conducts research in robotics, vision, speech
          understanding, theorem proving and distributed databases.
          While at SRI he performed initial debugging of the TCP/IP
          protocols in conjunction with BBN.

          Lynch has been active in computer networking since 1973.
          Prior to that he developed realtime software for missile
          decoy detection for the USAF.  He received undergraduate
          training in mathematics and philosophy from Loyola University
          of Los Angeles and obtained a Master's Degree in mathematics
          from UCLA in 1965.

          -------

          The Internet has grown because it solves simple problems in a
          simple a manner as possible.  Putting together a huge
          Internet has not been easy.  We still do not know how to do
          routing in a huge internet.  When you add the realworld
          requirement of commercial security and the desire for
          "classes of service" we are faced with big challenges.  I
          think this means that we have to get a lot more involved with
          operational provisioning considerations such as those that
          the phone companies and credit card firms have wrestled with.
          Hopefully we can do this and still maintain the rather
          friendly attitude that Internetters have always had.

     4.16 Dr. Jonathan B. Postel, IAB Member, RFC Editor

          Jon Postel joined ISI in March 1976 as a member of the
          technical staff, and is now Division Director of the
          Communications Division.  His current activities include a
          continuing involvement with the evolution of the Internet
          through the work of the various ISI projects on Gigabit
          Networking, Multimedia Conferencing, Protocol Engineering,
          Los Nettos, Parallel Computing System Research, and the Fast
          Parts Automated Broker.  Previous work at ISI included the
          creation of the "Los Nettos" regional network for the Los
          Angeles area, creating prototype implementations of several
          of the protocols developed for the Internet community,
          including the Simple Mail Transport Protocol, the Domain Name
          Service, and an experimental Multimedia Mail system.  Earlier
          Jon studied the possible approaches for converting the
          ARPANET from the NCP protocol to the TCP protocol.
          Participated in the design of many protocols for the Internet
          community.

          Before moving to ISI, Jon worked at SRI International in Doug
          Engelbart's group developing the NLS (later called Augment)
          system.  While at SRI Jon led a special project to develop
          protocol specifications for the Defense Communication Agency
          for AUTODIN-II.  Most of the development effort during this
          period at ARC was focused on the National Software Works.
          Prior to working at SRI, Jon spent a few months with Keydata
          redesigning and reimplementing the NCP in the DEC PDP-15 data
          management system used by ARPA.  Before Keydata, Jon worked
          at the Mitre Corporation in Virginia where he conducted a
          study of ARPANET Network Control Protocol implementations.

          Jon received his B.S. and M.S. in Engineering in 1966 and
          1968 (respectively) from UCLA, and the Ph.D. in Computer

          continues to participate in the Internet Activities Board and
          serve as the editor of the "Request for Comments" Internet
          document series.

          -------

          My first experience with the ARPANET was at UCLA when i was
          working in the group that became the Network Measurement
          Center.  When we were told that the first IMP would be
          installed at UCLA we had to get busy on a number of problems.
          We had to work with the other early sites to develop
          protocols, and we had to get our own computing environment in
          order -- this included creating a time-sharing operating
          system for the SDS Sigma-7 computer.  Since then the ARPANET
          and then the Internet have continued to grow and always
          faster than expected.  I think three factors contribute to
          the success of the Internet: 1) public documentation of the
          protocols, 2) free (or cheap) software for the popular
          machines, and 3) vendor independence.

          It has been an interesting twelve years in my professional
          life to participate in the ARPANET/Internet world, from the
          transition of the TENEX to TOPs-20 machines in 1979 to
          surviving the NCP to TCP transition in 1980.  Celebrating the
          achievement of the ISI 1000 Hour Club where one of our TOPs-
          20 machines set a record for staying up and running for 1000
          consecutive hours without crashing, to watching the cellular
          split of the ARPANET into the Milnet and Internet sides, and
          surviving the advent of Unix in 1985.  All in all, my most
          memorable times are the people who have contributed to the
          research and development of the Internet.  Lots of hard,
          intense work, coupled with creative, exciting fun.  As for
          the future, there is much discussion and enthusiasm about the
          next step in the evolution of the Internet.  An
          "international" Internet is on the very tip of the horizon.
          Utilizing the global Internet will improve the quality of
          collaborative research.  I'm looking forward.
