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


The Status of CLNP Multicast

Dave Marlow presented an update on the status of CLNP multicast.  He has
published an Internet-Draft on the subject, which is intended to be
multicast routing protocol independent, and is presented from the ES
viewpoint.  A number of comments have been received and have been
incorporated into the latest draft.

Some discussion ensued as to whether the complexity of the
network-to-data-link address mapping protocol was worthwhile.

The ``extra hop'' problem is widely viewed as being a show-stopper.
Dave presented an approach to address this problem.

Some concern was noted about the schedule of ISO progression of the
multicast work, given some of the problems still being addressed.  Lyman
Chapin suggested updating ISO with the status of the work in the IETF,
suggesting that they do not progress this work until these issues are
settled.


Electronic Availability of the Pertinent ISO Standards

Lyman Chapin updated the group on the electronic availability of the
pertinent ISO standards.  The document issue is a part of the broader
liaison issue.  A formal resolution from ISO/IEC JTC1 calls for making
the core network layer documents accessible; Lyman is comfortable
posting these documents as Internet-Drafts.

The second edition of CLNP was forwarded for publication as an
Internet-Draft; ES-IS will be next.  (Neither includes the multicast
extensions.)  TR9577 (Protocol Identification at the Network Layer) will
be ready soon.  IDRP is ready.  IS-IS is a problem due to the lack of a
machine-readable specification.  This problem is being examined.


Protocol Independent Multicasting

Dino Farinacci gave a short presentation on the status of Protocol
Independent Multicasting (PIM) in the IDMR Working Group.  He noted
there would be little difficulty in using PIM for multicast routing of
CLNP.


Flows in CLNP

Ross Callon presented his work on flows in CLNP. In this scheme, the
source NSEL is used to demultiplex flows between a single host pair.
The size of this field (eight bits) was a source of controversy and
there was concern that using the source NSEL might cause problems for
existing (non-TUBA) CLNP implementations.


TUBA Transition Document

Dave Piscitello gave an overview of his TUBA transition document.


Cellular Packet Data Network

Bob Brenner from GTE gave an overview of Cellular Packet Data Network
(CDPD). Market studies show 20-40 million wireless devices, plus another
20 million telemetry devices.  Market demand is greater than the ability
to provide service.

The question was raised as to why OSI was selected for CDPD. They could
not get sufficient address space, and felt that the IETF was not going
to solve the problem quickly enough.  They also wanted CMIP due to its
acknowledged nature.
