Hi. We sent this in to the CNRI folks earlier this month, but I neglected
to copy the list. Apologies,
	Mark

> 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 don't progress this work until these issues
> are settled.

> Lyman Chapin updated the group on the electronic availability of the

> 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 I-Ds.  This is possible due to the
> semantics of I-Ds being compatible with ISO "working documents."

> The second edition of CLNP was forwarded for publication as an I-D;
> 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 in the process of

> The size of this field (eight bits) was a source of controversy.

> Dave Piscitello gave an overview of his TUBA transition document.

> 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
> couldn't 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.
