RFC 4052                 IAB Liaison Management               April 2005


1.  Liaison Relationships and Personnel

  The IETF, as an organization, has the need to engage in direct
  communication or joint endeavors with various other formal
  organizations.  For example, the IETF is one of several Standards
  Development Organizations, or SDOs, and all SDOs including the IETF
  find it increasingly necessary to communicate and coordinate their
  activities involving Internet-related technologies.  This is useful
  in order to avoid overlap in work efforts and to manage interactions
  between their groups.  In cases where the mutual effort to
  communicate and coordinate activities is formalized, these
  relationships are generically referred to as "liaison relationships".

  In such cases, a person from the IETF is designated to manage a given
  liaison relationship; that person is generally called the "IETF
  liaison manager" to the other organization.  When the liaison
  relationship is expected to encompass a complex or broad range of
  activities, more people may be designated to undertake some portions
  of the communications, coordinated by the liaison manager.  Often,
  the other organization will similarly designate their own liaison
  manager to the IETF.

  This document is chiefly concerned with:

  o  the establishment and maintenance of liaison relationships, and

  o  the appointment and responsibilities of IETF liaison managers and
     representatives.

  The management of other organizations' liaison managers to the IETF,
  whether or not in the context of a liaison relationship, is outside
  the scope of this document.

  The IETF has chartered the Internet Architecture Board to manage
  liaison relationships.  Consistent with its charter [2], the IAB acts
  as representative of the interests of the IETF and the Internet
  Society in technical liaison relationships with other organizations
  concerned with standards and other technical and organizational
  issues relevant to the worldwide Internet.  Liaison relationships are
  kept as informal as possible and must be of demonstrable value to the
  IETF's technical mandate.  Individual participants of the IETF are
  appointed as liaison managers or representatives to other
  organizations by the IAB.

  In general, a liaison relationship is most valuable when there are
  areas of technical development of mutual interest.  For the most
  part, SDOs would rather leverage existing work done by other
  organizations than recreate it themselves (and would like the same
  done with respect to their own work).  Establishing a liaison
  relationship can provide the framework for ongoing communications to

  o  prevent inadvertent duplication of effort, without obstructing
     either organization from pursuing its own mandate;

  o  provide authoritative information of one organization's
     dependencies on the other's work.

2.  Aspects of Liaisons and Liaison Management

2.1.  Liaison Relationships

  A liaison relationship is set up when it is mutually agreeable and
  needed for some specific purpose, in the view of the other
  organization, the IAB, and the IETF participants conducting the work.
  There is no set process or form for this; the IETF participants and
  the peer organization approach the IAB, and after discussion come to
  an agreement to form the relationship.  In some cases, the intended
  scope and guidelines for the collaboration are documented
  specifically (e.g., see [3], [4], and [5]).

  In setting up the relationship, the IAB expects that there will be a
  mutual exchange of views and discussion of the best approach for
  undertaking new standardization work items.  Any work items resulting
  for the IETF will be undertaken in the usual IETF procedures, defined
  in [1].  The peer organization often has different organizational
  structure and procedures than the IETF, which will require some
  flexibility on the part of both organizations to accommodate.  The
  IAB expects that each organization will use the relationship
  carefully, allowing time for the processes it requests to occur in
  the other organization, and will not make unreasonable demands.

2.2.  Liaison Manager

  As described above, most work on mutually interesting topics will be
  carried out in the usual way within the IETF and the peer
  organization.  Therefore, most communications will be informal in
  nature (for example, Working Group (WG) or mailing list discussions).

  An important function of the liaison manager is to ensure that
  communication is maintained, productive, and timely.  He or she may
  use any applicable businesslike approach, from private to public
  communications, and bring in other parties as needed.  If a



Daigle & IAB             Best Current Practice                  [Page 3]

RFC 4052                 IAB Liaison Management               April 2005


  communication from a peer organization is addressed to an
  inappropriate party, such as being sent to the WG but not copying the
  Area Director (AD) or being sent to the wrong WG, the liaison manager
  will help redirect or otherwise augment the communication.

  IETF liaison managers should also communicate and coordinate with
  other liaison managers where concerned technical activities overlap.

  Since the IAB is ultimately responsible for liaison relationships,
  anyone who has a problem with a relationship (whether an IETF
  participant or a person from the peer organization) should first
  consult the IAB's designated liaison manager, and if that does not
  result in a satisfactory outcome, the IAB itself.

2.3.  Liaison Representatives

  The liaison manager is, specifically, a representative of the IETF
  for the purpose of managing the liaison relationship.  There may be
  occasion to identify other representatives for the same relationship.
  For example, if the area of mutual work is extensive, it might be
  appropriate to name several people as liaison representatives to
  different parts of the other organization.  Or, it might be
  appropriate to name a liaison representative to attend a particular
  meeting.

  These other liaison representatives are selected by the IAB and work
  in conjunction (and close communication) with the liaison manager.
  In some cases, this may also require communication and coordination
  with other liaison managers or representatives where concerned
  technical activities overlap.  The specific responsibilities of the
  liaison representative will be identified at the time of appointment.

2.4.  Liaison Communications

  Communications between organizations use a variety of formal and
  informal channels.  The stated preference of the IETF, which is
  largely an informal organization, is to use informal channels, as
  these have historically worked well to expedite matters.  In some
  cases, however, a more formal communication is appropriate, either as
  an adjunct to the informal channel or in its place.  In the case of
  formal communications, the established procedures of many
  organizations use a form known as a "liaison statement".  Procedures
  for sending, managing, and responding to liaison statements are
  discussed in [6].

3.  Summary of IETF Liaison Manager Responsibilities

  While the requirements will certainly vary depending on the nature of
  the peer organization and the type of joint work being undertaken,
  the general expectations of a liaison manager appointed by the IAB
  are as follows:

  o  Attend relevant meetings of the peer organization as needed and
     report back to the appropriate IETF organization any material
     updates.

  o  Carry any messages from the IETF to the peer organization, when
     specifically instructed.  Generally, these communications
     "represent the IETF", and therefore due care and consensus must be
     applied in their construction.

  o  Prepare occasional updates.  The target of these updates (e.g.,
     the IAB, an AD, a WG) will generally be identified upon
     appointment.

  o  Oversee delivery of liaison statements addressed to the IETF,
     ensuring that they reach the appropriate destination within the
     IETF, and ensure that relevant responses from the IETF are created
     and sent in a timely fashion.

  o  Work with the other organization to ensure that the IETF's liaison
     statements are appropriately directed and responded to in a timely
     fashion.

  o  Communicate and coordinate with other IETF liaison managers and
     representatives where concerned technical activities overlap.

4.  Approval and Transmission of Liaison Statements

  It is important that appropriate leadership review be made of
  proposed IETF liaison statements and that those writing such
  statements, who claim to be speaking on behalf of IETF, are truly
  representing IETF views.

  All outgoing liaison statements will be copied to IETF Secretariat
  using procedures defined in [6] or its successors.

  For a liaison statement generated on behalf of an IETF WG, the WG
  chair(s) must create a statement based on appropriate discussions
  within the WG to ensure working group consensus for the position(s)
  presented.  The chair(s) must have generated or must agree with the
  sending of the liaison statement, and must advise the AD(s) that the
  liaison statement has been sent by copying the appropriate ADs on the
  message.

  For a liaison statement generated on behalf of an IETF Area, the
  AD(s) must have generated or must agree with the sending of the
  liaison statement.  If the liaison statement is not sent by the ADs,
  then their agreement must be obtained in advance and confirmed by
  copying the ADs on the message.

  For a liaison statement generated on behalf of the IETF as a whole,
  the IETF Chair must have generated or must agree with the sending of
  the liaison statement.  If the liaison statement is not sent by the
  IETF Chair, then his or her agreement must be obtained in advance and
  confirmed by copying the IETF Chair on the message.

  For a liaison statement generated by the IAB, the IAB Chair must have
  generated or must agree with the sending of the liaison statement.
  If the liaison statement is not sent by the IAB Chair, then his or
  her agreement must be obtained in advance and confirmed by copying
  the IAB Chair on the message.

  In cases where prior agreement was not obtained as outlined above,
  and the designated authority (AD, IETF Chair, or IAB Chair) in fact
  does not agree with the message, the designated authority will work
  with the liaison manager to follow up as appropriate, including
  emitting a revised liaison statement if necessary.  Clearly, this is
  a situation best avoided by assuring appropriate agreement in advance
  of sending the liaison message.

5.  Security Considerations

  The security of the Internet is not threatened by these procedures.
