-
- Attached to this liaison statement is SC 6 N 8420 entitled "Statement
- of Expected Benefits Regarding Liaison between the Internet Society
- and ISO/TEC JTC 1/SC 6", which SC 6 is sending to JTC 1 in support of
- its liaison initiative with the Internet Society and its principal
- Internet standards-making body (the IETF).
-
- It is apparent to SC 6 that there are clear benefits to be obtained
- from identifying and agreeing on common goals and objectives from
- both the ISO and Internet perspectives. SC 6 offers a draft set of
- goals and benefits in N 8420. In order for the current liaison
- initiative to succeed, it is essential for the Internet Society and
- JTC 1, in particular its SC 6, to adopt a common "memorandum of
- understanding (MOU)" that expresses and agreement between affected
- parties concerning the expected goals and benefits of liaison. SC 6
- hopes to pursue such an MOU with the Internet Society, with the
- objective of making the MOU the basis of a liaison relationship. It
- is expected that such an MOU would also address the change control
- mechanisms. SC 6 views favourably granting Category A liaison to the
- Internet Society, but the nature and terms of the liaison
- relationship will of course be matters of agreement between the ITTF,
- JTC 1 and the Internet Society.
-
- Identification of Issues Concerning Effective Liaison between the
- Internet Society and SC6
-
-
- 1. SC 6 recognizes the existence of a multiprotocol environment
- that includes both open and proprietary standards and that
- TCP/IP forms an essential component of this environment.
-
-
- 2. SC 6 observes that there are a number of different initiatives
- which have either been taken or may be undertaken:
-
-
- - The IETF is working on issues related to the deployment and
- operations of CLNP in the Internet ("Guidelines for NSAP
- allocation"; NOOP WG0. CLNP was adopted by SC 6 in 1988
- because it was the best available protocol for
- connectionless internetworking in the context of OSI. SC 6,
- therefore, strongly encourages this initiative and views it
- as a very positive development.
-
- - The IETF is considering the use of TUBA as its IPng
- protocol. SC 6 encourages fair consideration of this
- approach.
-
- - The IETF is already working on adapting the use of OSI
- routeing protocols (ISIS, IDRP) in the Internet.

-
-
-
- - Both SC6 and the IETF are working on the provision of new
- network layer capabilities such as multicast, mobility, and
- support for multimedia applications.
-
-
- 3. These areas should be evaluated independently and SC 6
- encourages collaboration in all of them. This work should
- continue regardless of the status of discussions on liaison
- relationships.

- 3 Statement of Expected Benefits Resulting From Liaison Between ISO/IEC
- JTC1/SC6 and the Internet Society
-
-
-
-
- Background on OSI Protocols and Related Work by the Internet Society
-
-
- Interconnection and internetworking protocols have been developed by
- ISO/IEC and ITU-T in accordance with the OSI reference model
- architecture. They are known colloquially as OSI protocols. The
- Internet community has developed difference protocols for the same
- basic purposes. These protocols are known formally as the Internet
- Protocol Suite (IPS) but they are nearly always referred to
- colloquially as TCP/IP protocols (Transmission Control
- Protocol/Internet Protocol). TCP and IP incorporate the functions of
- the OSI class 4 transport and connectionless Network layer protocols,
- ie the networking part of the IPS.
-
-
- Goals and Benefits
-
-
- The establishment and pursuit of a collaborative effort is expected
- to:
-
-
- - Simplify the deployment and operation of the global
- communications infrastructure;
-
- - Facilitate and accelerate the growth of a global communications
- infrastructure based on open systems networking standards;
-
- - Reduce the complexity and cost of open systems networking to
- the users and providers of network products and services by
- reducing the number of alternatives.

-
-
- - 4 -
-
-
-
- - More efficiently use the scarce worldwide resource of
- networking experts involved in the definition of new and
- improved open systems networking protocols;
-
- - Enable ISO/IEC to develop and evolve its standards in such a
- way as to promote their usage within the global communications
- infrastructure.
-
- The IETF and JTC 1 SC 6 have begun to develop new capabilities such
- as multicast mobility, and multimedia applications. Effective
- liaison will focus the resources of the two groups on common
- solutions to these problems, accelerating the development of these
- new capabilities and their deployment within the global
- communications infrastructure.
-
-
- Methodology
-
-
- Details of the technical interaction will be developed jointly by SC
- 6 and the Internet Society within the terms of agreement that may be
- reached between the Internet Society and JTC 1 within respect to
- liaison.
-
-
-
- Background to the Liaison Initiative
-
-
- At its 1992 plenary meeting in San Diego, SC 6 instructed its
- chairman in initiate a dialogue with external bodies with whom SC 6
- shares a mutual interest, such as the Internet Architecture Board
- (IAB) and the Frame Relay Forum, with a view to establishing liaison
- relationships between those bodies and SC 6 (see Resolution 138 of SC
- 6/N 7684). In the absence of a chairman of SC 6 following the San
- Diego meeting, the action was undertaken in late 1992 on an interim
- Society (ISOC) and the Internet Architecture Board (IAB).
-
- Discussion of the purpose and form of a liaison relationship between
- SC 6 and the Internet Society took place over a period of months that
- included IAB participation in the February 1993 meetings of SC 6
- working groups in London and Mr Houldsworth's participation in a
- meeting of the IAB in Columbus, Ohio in March 1993.
-
- JTC 1 was informed of these liaison initiatives at their March 1993
- plenary meeting in Berlin. JTC 1 instructed SC 6 to proceed
- immediately with the establishment of a Category C relationship with
- the IAB in accordance with he JTC 1 Directives (see Resolution 44 of
- SC 6 N 8055). JTC 1 also instructed other specific SCs to consider
- their requirements for liaison with the Internet Society.

-
- [NOTE: The IAB, which desires a relationship with JTC 1 and its
- subcommittees broader than that offered by a Category C relationship
- with SC 6, has written to the ITTF to request Category A liaison
- status with JTC 1. Pending the completion of this initiative with
- JTC 1, the IAB has explicitly stated its reluctance to enter into a
- Category C relationship with SC 6 (or with SC 21 or SC 18, which have
- also discussed the possibility of establishing Category C
- relationships with the Internet Society).]
-
- The JTC 1 Directives state that a subcommittee wishing to establish a
- liaison must provide a statement of the benefits that the
- relationship will bring. Therefore, in accordance with clause 4.3.2
- of the JTC 1 Directives, the attached document is submitted to JTC 1
- to assist in the formal establishment of a liaison relationship.
-
- SC 6 proposes to JTC 1 that a Category A liaison relationship between
- SC 6 and the Internet Society would be mutually beneficial. Further,
- subject to JTC 1 approval SC 6 offers to develop with the Internet
- Society a "Memorandum of Understanding" (MOU) describing the precise
- nature of the liaison relationship. SC 6 suggests that the subject
- MOU could be applicable to the situation in which other JTC 1 SCs
- might find themselves with respect to the liaison with the Internet
- Society.
