Hi: Some comments to the SIP/SDP static dictionary for signalling compression, draft-ietf-sipping-sigcomp-sip-dictionary-04.txt In the SIP input strings (Appendix A): - As RFC 3261 mandates the implementation of TCP in UAs and proxies, I suspect that TCP is going to be so common as UDP. Therefore, the priority of all the strings where "TCP" is involved should be the same as the "UDP counterpart. My suggestion: "SIP/2.0/TCP " 2 [2] 25.1 "[CRLF]Via: SIP/2.0/TCP " 1 [2] 20.42 - I believe the ACK string should get prioirty 1, as it is mandated as part of all the session invitations. "ACK" 1 [2] 25.1 "ACK " 1 [2] 25.1 - My suggestion is to upgrade MESSAGE to priority 3. I suspect that it is going to be used quite a lot more than the rest of the strings that are falling into priority 4. "MESSAGE" 3 [20] 9 "MESSAGE " 3 [20] 9 - Content-Length must be present in all the SIP messages. Therefore, it should be priority 1: "[CRLF]Content-Length: " 1 [2] 20.14 - The Event string contains a few extra white spaces after the column. It should be: "[CRLF]Event: " 3 [8] 8.2.1 - I guess Record-Route should be priority 2: "[CRLF]Record-Route: " 2 [2] 20.30 In the SDP input strings (Appendix B): - According to the latest version of the drafts, the "mikey" extension is written in lower case. We have written it in uppercase, so we should replace its entry with: - "[CRLF]a=key-mgmt:mikey" 4 [28] 2.1, [29] 6 NITs: - In section 2, there are a few paragraphs (6 to 12) that describe the column layout of the input strings. As the input strings moved to appendixes A and B, I guess these paragraphs should moved there as well. The problem is that the text should be repeated in each annex. - Reference 18 needs to add the ".txt" to the file name. - Appendixes A and B, second paragraphaph: The terminology should be consistent, because in one sentence we speak about *lower* priority values, whereas at the end we speak about *small* priority values. That's all. /Miguel -- Miguel-Angel Garcia Oy LM Ericsson AB Jorvas, Finland mailto:Miguel.A.Garcia@ericsson.com Phone: +358 9 299 3553 mailto:Miguel.A.Garcia@piuha.net Mobile: +358 40 5140002 _______________________________________________ Sipping mailing list https://www1.ietf.org/mailman/listinfo/sipping This list is for NEW development of the application of SIP Use sip-implementors@cs.columbia.edu for questions on current sip Use sip@ietf.org for new developments of core SIP
