IP Payload Compression Protocol (IPPCP) working group minutes Chair: Naganand Doraswamy Area Director: Thomas Narten mailing address: ippcp@external.cisco.com The agenda for the meeting was 1. Status - Naganand 2. Architecture/Protocol draft- Avram Shacham 3. LZS draft- Bob Monsour 4. Next Steps- Naganand 1. Status The architecture draft went through the working group last call with minor editorial changes. There were no major changes to necessitate the need for another last call. Thomas Narten had some comments which needs to be incorported into the draft. There was some discussion as to how to deal with getting new transform ID's from IANA. It was decided that we will follow the same model as the IPsec working group for getting new transform ID's. The working group agreed that we should not mandate any compression algorithm. The working group also decided not to define tunnel mode for the protocol. 2. Architecture/Protocol draft Avram discussed the changes in the draft before it went to the last call. The latest draft is draft-ietf-ippcp-protocol-03.txt. Cisco's prototype implementation was discussed. The prototype has the new header format done. ISAKMP negotiation is in progress. Avram suggested using some kind of guidelines for the drafts describing new algorithms. These include - Getting a transform ID < 64 for manual setup - Getting a trasnform ID for DOI and define parameters if any - Guidelines on non-expansion - threshold - compressibility It was also decided not to restrict the CPI values 0-63 only for manual setup but also use it for ISAKMP for well known algorithms. 3. LZS Compression draft Bob discussed the changes to the draft and agreed to incorporate the guidelines in the draft. This draft will become an informational RFC. Bob also discussed licensing issues for LZS both hardware and software. 4. Next Steps It was agreed that interoperability is most important. IPPCP will be tested in the next IPsec workshop. The architecture draft will move forward after review from IESG. There was also encouragement for people to write drafts for other compression algorithms.
