Elwyn,
Which do you think is better: a 05- or 04-conformant impl for this ietf? does this change much to interop?

Hi.
The new version of the GIMPS specification was published yesterday.
There are some minor changes which affect what CLEO is doing at present:
- NTLP common header: Now contains a message type field in some of the
reserved bits together with a bit saying which source address is being used (data sender or GIMPS hop). This is an improvement ... it makes message parsing much easier as you don't need to work out what sort of message it is from heuristics.
- Clears up a possible misunderstanding on my part regarding the CONFIRM
message. I thought this was sent on the new MA as the first message when it was set up. This is not so... it is only sent on the MA if we are reusing an existing MA (which means the RESPONSE message arrives on the MA). In the case of a new MA, the CONFIRM message is sent in Dmode so that responders that are postponing setting up MRS for as long as possible need only set it up once the CONFIRM arrives. This affects Bernd primarily ... some details in the FSM.
I haven't had chance to do a really detailed read through, but these were the headlines that I spotted on first pass (it is 92 pages now!).
Regards, Elwyn

A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Next Steps in Signaling Working Group of the IETF.
Title : GIMPS: General Internet Messaging Protocol for Signaling Author(s) : H. Schulzrinne, R. Hancock Filename : draft-ietf-nsis-ntlp-05.txt Pages : 92 Date : 2005-2-23
This document specifies protocol stacks for the routing and transport of per-flow signaling messages along the path taken by that flow through the network. The design uses existing transport and security protocols under a common messaging layer, the General Internet Messaging Protocol for Signaling (GIMPS), which provides a universal service for diverse signaling applications. GIMPS does not handle signaling application state itself, but manages its own internal state and the configuration of the underlying transport and security protocols to enable the transfer of messages in both directions along the flow path. The combination of GIMPS and the lower layer transport and security protocols provides a solution for the base protocol component of the "Next Steps in Signaling" framework.

NOTE: The mail server at ietf.org can return the document in MIME-encoded form by using the "mpack" utility. To use this feature, insert the command "ENCODING mime" before the "FILE" command. To decode the response(s), you will need "munpack" or a MIME-compliant mail reader. Different MIME-compliant mail readers exhibit different behavior, especially when dealing with "multipart" MIME messages (i.e. documents which have been split up into multiple messages), so check your local documentation on how to manipulate these messages. Below is the data which will enable a MIME compliant mail reader implementation to automatically retrieve the ASCII version of the Internet-Draft.
