Forwarding: ISO/IEC/JTC1/SC6 London Meeting ( OSI v TCP/IP status update )
IPSECers:
As you can see from the attached trip report, there is a possibility that CLNP
will be adopted as IPv7. At the next IETF meeting we should try an determine
the likelihood of this alternative. If CLNP is in the Internet's future, then
I suggest that NLSP-CL is the correct security protocol. If CLNP/NLSP-CL is
the long term solution, the I suggest that IP/NLSP-CL/Convergence Protocol is
the correct short term solution.

An ad-hoc meeting to progress the initiative to establish liaison between
ISO/IEC and the Internet Society was held during the SC6 interim working group
meetings in London, February 8 -12th. 1993.
The initiative is not one-sided, as the Internet Society has also written to
the ISO Central Secretariat requesting Category A liaison status, and this
request will be progressed as quickly as possible through the ISO/IEC
Management Committee JTC1.
The lively and enthusiastic London meeting attracted over 40 delegates from the
SC6 working groups, and was chaired by Jack Houldsworth who has accepted the
responsibility to progress the initiative on behalf of SC6. ( Jack has been
chairman of the BSI IST/6 committee for many years, and is well known in the
industry as one of the founding fathers of OSI ).
A. Lyman Chapin, chairman of the IAB ( Internet Architecture Board ),
represented the Internet Society by agreement with Vinton Cerf, the President
of the Board of Trustees of the Internet Society.
Jack Houldsworth opened the meeting by crystallising the key objectives of
liaison as:- "the convergence of the existing TCP/IP and OSI interconnection
and interworking protocols, and the ongoing joint development of a common
platform to support future multimedia and hypermedia applications". He
highlighted the benefits of a converged scenario, which are the reduction of
development effort required by the industry and an easier route to global
interconnection. He was particularly anxious to halt the current media rhetoric
about the rumoured "battle of attrition" between TCP/IP and OSI which is
confusing users and tearing the industry apart. He urged all delegates to
ensure that the liaison initiative is promulgated to all possible areas of the
media on the grounds that this is a better story than the worn out open warfare
rhetoric. He also believes that suppliers of other proprietry protocols will
follow suit if Internet and OSI are seen to be converging, and that convergence
is the only route to an "all-pervasive" global network.
Lyman Chapin cautioned that many Internet members come from an academic
background and enjoy a lively experimental environment. They have no commercial
commitment to deliver products to customers for global interconnection and
there is a requirement to convince them about the benefits of a converged
solution. ( Some Internet members actually believe that competition between two
solutions is a good thing.)
Lyman went on to report that the Internet community is currently reviewing
protocol enhancements to solve some known problems with TCP/IP, and that
several alternative solutions are on the table. One of these is to run the
Internet TCP and UDP protocols over the OSI Internet Protocol, this proposal
being known as TUBA ( TCP / UDP over Bigger Addresses ).
It was agreed that SC6 should support the TUBA proposal, and that this view
should be conveyed to the IAB as quickly as possible to make sure that the
window of opportunity is not missed. ( Several delegates offered to contact the
Network OSI Operations Working Group ( noop@merit.edu) to convey this view on
behalf of their parent organisations.)
The meeting also agreed to examine "fast track" operating methods for
collaborative projects with Internet. This could be similar to the way that ISO
/ IEC and the IEEE work together on LAN standards.
A joint programme to create a platform for multimedia and hypermedia
applications would have similar content to the Enhanced Communications
Functions and Facilities ( ECFF) programme which is just getting under way in
SC6, and a major share of the protocol enhancement work could be handled by the
Internet community to share the load. The "fast track" initiative will be
progressed with the ISO / IEC Management Committee JTC1.
It was also agreed that ISO / IEC needs to release relevant ISO documents to
the Internet Community for use within their electronic distribution system if
collaboration is to work.
( This does not imply release of copywrite, but it is accepted that relevant
ISO documents should be available electronically in the same way as RFC's). SC6
will request the release of key documents through JTC1.
Jack Houldsworth will attend the next IAB meeting ( to be held during the IETF
meeting in Columbus, Ohio at the end of March) on behalf of SC6 to convey the
enthusiasm of ISO/IEC for future collaboration, and will also make it known
that the TUBA proposals would be favourably received by ISO / IEC. Jack will
also attend the European IETF meeting in Amsterdam in July to maintain liaison
impetus and continuity as SC6 runs up to its Plenary meeting in Seoul next
September.
