CURRENT_MEETING_REPORT_
Reported by Vladimir Sukonnik/Process Software Corporation
Minutes of the TP/IX Working Group (TPIX)
The TPIX Working Group met jointly with the TUBA Working Group and also
met in a second independent session. The agenda for that meeting was:
o Introduce and discuss CATNIP
o Review TP/IX charter and name
The meeting started with Ross Callon introducing the concept of the
Forward Cache Identifier, or handle, to be used to speed up processing
in routers. A downstream router may send an ICMP message offering an
FCI for a particular source, destination, and type of service. The
source may then use the FCI in its packet instead of fully specified
source and destination addresses. Using the FCI will achieve two goals:
smaller packet size and faster processing in the router.
CATNIP
Robert Ullmann introduced CATNIP. CATNIP is a revision of the TP/IX
proposal. The TP/IX packet has been extended to include a Forward Cache
Identifier and NSAP-style source and destination addresses. Using a
NSAP-style address, CATNIP could be used to represent IPv4, IPX and OSI
protocols. CATNIP could also be used to connect CLNP systems to IPv4
and IPX systems.
Several people suggested that placing the Forward Cache Identifier in
the first longword of the packet may speed up processing. Robert
pointed out two reasons for not doing so. First, the first byte must be
reserved for NLPID field. Second, it was observed that any current or
future processor will be loading at least 64 bits in parallel anyway.
It is also easier to make FCI fixed field rather than a variable size.
TCP used to be part of the TP/IX proposal. The working group felt that
it would be better to separate TCP (and UDP) from the CATNIP proposal
and have them addressed as separate issues.
The working group decided to remove RAP (RFC 1476) from its charter, to
be developed separately. It was noted by Dave Katz and others that
IS-IS will work fine with CATNIP, as will the IDRP and other methods;
the existing OSI routing could be used for CATNIP's addressing scheme
without any changes.
A concern was raised that the selection field in the CATNIP header may
not be long enough. It seems, however, that 16 bits is a reasonable
size for fields that assign one code point to each of a set of protocols
(at least below application layer). It's hard to see us designing more
than 65000 transport layer protocols.
The TP/IX working group also defined milestones for Seattle:
o Rob will add additional details and publish CATNIP as an
Internet-Draft.
o Rob will write the white paper requested by the IPng directorate as
soon as the outline is available.
o Vladimir will rewrite TP/IX charter and work with Scott Bradner on
renaming the working group to CATNIP.
o The group will plan on meeting jointly with TUBA for one session in
Seattle, and will continue to coordinate efforts to find as much
common ground as possible.
