CURRENT_MEETING_REPORT_

Reported by Mark Knopper/Merit

Minutes of the TCP/UDP over CLNP-Addressed Networks Working Group (TUBA)

The meeting was called to order by Mark Knopper and Peter Ford,
co-chairs.  Dave Katz volunteered to act as recording secretary.  Mark
Knopper presented the agenda.


CLNP Multicast

Dave Marlow reported on the progression of CLNP Multicast work at the
recent ISO SC6 meeting in Seoul.  There are currently four documents in
progression---changes to the network addressing addendum, extensions to
the CLNP and ES-IS protocols, and a change to the network service
definition.  Documentation of these changes will be released as an
Internet-Draft.

The Group Network Addressing addendum has progressed to Full Standard
status.  This document describes the syntax of multicast NSAP addresses.

The extensions to CLNP have been issued for Draft Amendment (DAM)
ballot.  This is the final balloting stage before full standardization
(similar to Draft Internet Standard status).  The changes include a new
packet type (so that unicast-only routers do not try to default-forward
multicast packets, which could create packet-exploder loops) and two
types of scope control.

The ES-IS extensions have also been issued for DAM ballot.  These
changes provide for the ability of end systems to join multicast groups,
as well as for dynamic mapping between network and subnetwork multicast
addresses.

The change to the Network Service definition adds multicast capability
to the abstract network service.

There has been no significant work on multicast routing, as ANSI is
looking to work with the IETF for technical contribution in this area.
Possibilities include MOSPF-like extensions to IS-IS, CBT, and ESL.


NSAP Addressing Guidelines Document

Ross Callon reported on the status of the NSAP Addressing Guidelines
document.  A new version has been made available as an Internet-Draft.
Changes in the new version consist primarily of updated document
references.  Several people mentioned that they thought the current
document was overly ``backbone-centric,'' as the Internet routing
hierarchy has changed considerably since the document was originally
written.  An action item was taken to recast this section of the
document.


CLNP Projects

Yakov Rekhter gave a brief overview of two projects just getting started
in ISO concerning CLNP. The first describes a coding method for option
types that provides a hook for transparently adding options.  The code
indicates which options are required to be processed by routers and/or
hosts, even when the option is otherwise unrecognized.

The second project extends the Quality of Service (QoS) option to
provide a bit to request strong (vs.  weak) QoS forwarding, as well as a
bit to say whether or not the requested OoS was delivered along the
entire path when weak QoS forwarding is in effect.


CLNP Mobility

A discussion then ensued on the subject of CLNP mobility.  Mark Knopper
briefly described CDPD, a specification for cellular mobile data service
from a consortium of cellular carriers.  The system uses CLNP as the
primary protocol, and provides IP service using IP-over-CLNP
encapsulation.  The mobility protocol is quite similar to ongoing work
in the Mobile IP Working Group.  The group discussed whether or not it
should be proactive, or wait for the Mobile IP Working Group to settle.
Yakov Rekhter and Dave Piscitello agreed to recast the mobile IP
document in terms of CLNP and make it available as an Internet-Draft.


Extensions to OSI for Use in the Internet BOF (OSIEXTND)

Dave Katz briefly updated the group on the status of OSIEXTND. The IESG
has issued a formal statement limiting official IETF participation to
ongoing ``OSI-related work.''  No new working groups in this area will
be chartered until such time as the liaison issue between ISO and ISOC
has been settled, or until six months pass.  What was not clearly stated
at the time was that this action does not apply to anything that could
be construed as in support of TUBA. As the majority of the items of work
proposed at the OSIEXTND BOF are directly related to TUBA, the net
effect is that work will progress in existing working groups.

To that end, Dave Katz then presented a proposed extension to ES-IS to
add functionality to the standard dynamic NSAP address assignment
function.  The extension would allow the end system to suggest a system
ID to the entity assigning the addresses, which would then fill in the
remainder of the NSAP address if it so chose.  A second contribution
describing the overall dynamic address assignment mechanism was also
presented.  Both documents will be made available as Internet-Drafts.


Dual Stack Transition

Peter Ford presented his draft document on the Dual Stack Transition
plan.  It is an ``inside out'' approach that begins with infrastructure
deployment.  It was pointed out that this transition framework needed to
be completed as soon as possible.  The document is available as an
Internet-Draft.
