                                Notes

  This memo is a report on the Gateway Special Interest Group Meeting
  that was held at ISI on 28 and 29 February 1984.  Robert Hinden of
  BBNCC chaired, and Jon Postel of ISI hosted the meeting.
  Approximately 35 gateway designers and implementors attended.  These
  notes are based on the recollections of Jon Postel and Mike Muuss.
  Under each topic area are Jon Postel's brief notes, and additional
  details from Mike Muuss.  This memo is a report on a meeting.  No
  conclusions, decisions, or policy statements are documented in this
  note.

897     Postel       Feb 84      Domain Name System Implementation
                                Schedule

  This memo is a policy statement on the implementation of the Domain
  Style Naming System in the Internet.  This memo is a partial update
  of RFC 881.  The intent of this memo is to detail the schedule for
  the implementation for the Domain Style Naming System.  The names of
  hosts will be changed to domain style names.  Hosts will begin to use
  domain style names on 14-Mar-84, and the use of old style names will
  be completely phased out before 2-May-84.  This applies to both the
  ARPA research hosts and the DDN operational hosts.  This is an
  official policy statement of the ICCB and the DARPA.

                                Messages

  This memo is distributed as an RFC only to make this information
  easily accessible to researchers in the ARPA community.  It does not
  specify an Internet standard.  This RFC defines the standard format
  for interchange of Network News articles among USENET sites.  It
  describes the format for articles themselves, and gives partial
  standards for transmission of news.  The news transmission is not
  entirely standardized in order to give a good deal of flexibility to
  the individual hosts to choose transmission hardware and software,
  whether to batch news and so on.

849     Crispin      May 83      Suggestions for Improved Host Table
                                Distribution

  This RFC actually is a request for comments.  The issue dealt with is
  that of a naming registry update procedure, both as exists currently
  and what could exist in the future.  None of the proposed solutions
  are intended as standards at this time; rather it is hoped that a
  general consensus will emerge as the appropriate solution, leaving
  eventually to the adoption of standards.

831     Braden       Dec 82      Backup Access to the European Side of
                                SATNET

  The purpose of this RFC is to focus discussion on a particular
  Internet problem:  a backup path for software maintenance of the
  European sector of the Internet, for use when SATNET is partitioned.
  We propose a mechanism, based upon the Source Routing option of IP,
  to reach European Internet sites via the VAN Gateway and UCL.  This
  proposal is not intended as a standard at this time.

  The purpose of this RFC is to present a method of Converting Protocol
  Addresses (e.g., IP addresses) to Local Network Addresses (e.g.,
  Ethernet addresses).  This is an issue of general concern in the ARPA
  Internet Community at this time.  The method proposed here is
  presented for your consideration and comment.  This is not the
  specification of an Internet Standard.

825     Postel       Nov 82      Request for Comments on Requests for
                                Comments

  This RFC is intended to clarify the status of RFCs and to provide
  some guidance for the authors of RFCs in the future.  It is in a
  sense a specification for RFCs.

824     MacGregor    Aug 82      The Cronus Virtual Local Network

  The purpose of this note is to describe the CRONUS Virtual Local
  Network, especially the addressing related features.  These features
  include a method for mapping between Internet Addresses and Local
  Network addresses.  This is a topic of current concern in the ARPA
  Internet community.  This note is intended to stimulate discussion.
  This is not a specification of an Internet Standard.

823     Hinden       Sep 82      The DARPA Internet Gateway

  This RFC is a status report on the Internet Gateway developed by BBN.
  It describes the Internet Gateway as of September 1982.  This memo

  procedures, however, this is not an implementation specification, and
  such details are subject to change.

822     Crocker      Aug 82      Standard for the Format of ARPA
                                Internet Text Messages

  This document revises the specifications in RFC 733, in order to
  serve the needs of the larger and more complex ARPA Internet.  Some
  of RFC 733's features failed to gain adequate acceptance.  In order
  to simplify the standard and the software that follows it, these
  features have been removed.  A different addressing scheme is used,
  to handle the case of internetwork mail; and the concept of
  re-transmission has been introduced.  Obsoletes RFC 733, NIC 41952.

821     Postel       Aug 82      Simple Mail Transfer Protocol

  The objective of Simple Mail Transfer Protocol (SMTP) is to transfer
  mail reliably and efficiently.  SMTP is independent of the particular
  transmission subsystem and requires only a reliable ordered data
  stream channel.  Obsoletes RFC 788, 780, and 772.

                                Internet User Applications

  This RFC is an attempt to clarify the generalization of the Domain
  Naming Convention, the Internet Naming Convention, and to explore the
  implications of its adoption for Internet name service and user
  applications.

818     Postel       Nov 82      The Remote User Telnet Service

  This RFC is the specification of an application protocol.  Any host
  that implements this application level service must follow this
  protocol.

  This RFC describes the portion of fault isolation and recovery which
  is the responsibility of the host.

815     Clark        Jul 82      IP Datagram Reassembly Algorithms

  This RFC describes an alternate approach of dealing with reassembly
  which reduces the bookkeeping problem to a minimum, and requires only
  one buffer for storage equal in size to the final datagram being
  reassembled, which can reassemble a datagram from any number of
  fragments arriving in any order with any possible pattern of overlap
  and duplication, and which is appropriate for almost any sort of
  operating system.

814     Clark        Jul 82      Name, Addresses, Ports, and Routes

  This RFC gives suggestions and guidance for the design of the tables
  and algorithms necessary to keep track of these various sorts of
  identifiers inside a host implementation of TCP/IP.

813     Clark        Jul 82      Window and Acknowledgement Strategy in
                                TCP

  This RFC describes implementation strategies to deal with two
  mechanisms in TCP, the window and the acknowledgement.  It also
  presents a particular set of algorithms which have received testing
  in the field, and which appear to work properly with each other.
  With more experience, these algorithms may become part of the formal
  specification, until such time their use is recommended.

  environment.

810     Feinler      Mar 82      DoD Internet Host Table Specification

  This RFC specifies a new host table format applicable to both ARPANET
  and Internet needs.  In addition to host name to host address
  translation and selected protocol information, we have also included
  network and gateway name to address correspondence, and host
  operating system information.  This RFC obsoletes the host table
  described in RFC 608.

809     Chang        Feb 82      UCL Facsimile System

  held three years earlier to discuss the state of computer mail in the
  ARPA community and to reach some conclusions to guide the further
  development of computer mail systems such that a coherent total mail
  service would continue to be provided.

805     Postel       Feb 82      Computer Mail Meeting Notes

  This RFC consists of notes from a meeting that was held at USC
  Information Sciences Institute on 11 January 1982, to discuss
  addressing issues in computer mail. The major conclusion reached at
  the meeting is to extend the "username@hostname" mailbox format to
  "[email protected]", where the domain itself can be further
  strutured.

804     CCITT        Jan 82      CCITT Draft Recommendation T.4

  This is the CCITT standard for group 3 facsimile encoding.  This is
  useful for data compression of bit map data.

                                Transcoding

  The first part of this RFC describes in detail the Dacom 450 data
  compression algorithms and is an update and correction to an earlier
  memorandum.  The second part of this RFC describes briefly the Dacom
  500 data compression algorithm as used by the INTELPOST
  electronic-mail network under development by the US Postal Service
  and several foreign administrators.

802     Malis        Nov 81      The ARPANET 1822L Host Access Protocol

  This document proposed two major changes to the current ARPANET host
  access protocol.  The first change will allow hosts to use logical
  addressing (i.e., host addresses that are independent of their
  physical location on the ARPANET) to communicate with each other, and
  the second will allow a host to shorten the amount of time that it
  may be blocked by its IMP after it presents a message to the network
  (currently, the IMP can block further input from a host for up to 15
  seconds).  See RFCs 852 and 851.

801     Postel       Nov 81      NCP/TCP Transition Plan

  This RFC discusses the conversion of hosts from NCP to TCP.  And
  making available the principle services:  Telnet, File Transfer, and
  Mail.  These protocols allow all hosts in the ARPA community to share
  a common interprocess communication environment.
