Hi, >From tsvarea-sipchange the requirements for P- headers are: 1. Expert Review 2. No option tags, response codes, or methods 3. No overlap with planned/chartered extensions 4. Purely informational in nature 5. Does not undermine security 6. Clearly documented in RFC 7. Appropriate applicability statement I've taken a stab at documenting compliance with these requirements. I've also included an evaluation of call-auth as a comparison. Please note that in future proposed P- headers should go through SIPPING. draft-ietf-sip-call-auth 1. Expert Review Via the SIP working group as WG document 2. No option tags, response codes, or methods OK 3. No overlap with planned/chartered extensions No overlap 4. Purely informational in nature OK 5. Does not undermine security Minor caveats, well documented 6. Clearly documented in RFC OK 7. Appropriate applicability statement Yes, very narrow in scope draft-ietf-sip-asserted-identity 1. Expert Review Via WG as WG document 2. No option tags, response codes, or methods OK 3. No overlap with planned/chartered extensions Some overlap with future crytographic identity work, scope of overlap intentionally narrow 4. Purely informational in nature OK 5. Does not undermine security Minor caveats, usage well documented 6. Clearly documented in RFC OK 7. Appropriate applicability statement Yes, very narrow scope draft-garcia-sip-visited-network-id 1. Expert Review some review from SIP WG 2. No option tags, response codes, or methods OK 3. No overlap with planned/chartered extensions No overlap 4. Purely informational in nature OK 5. Does not undermine security Negligible impact, well documented 6. Clearly documented in RFC OK 7. Appropriate applicability statement Needs to provide more general usage guidance draft-garcia-sip-called-party-id 1. Expert Review some review from SIP WG 2. No option tags, response codes, or methods OK 3. No overlap with planned/chartered extensions some overlap with request-history work, very narrow in scope 4. Purely informational in nature OK 5. Does not undermine security Some privacy concerns 6. Clearly documented in RFC OK 7. Appropriate applicability statement Needs to provide more general usage guidance, Should mention the partial overlap with request history draft-garcia-sip-associated-uri 1. Expert Review some review from SIP WG 2. No option tags, response codes, or methods OK 3. No overlap with planned/chartered extensions No overlap 4. Purely informational in nature OK 5. Does not undermine security Some privacy concerns, can be addressed with standard mechanisms 6. Clearly documented in RFC OK 7. Appropriate applicability statement Needs to provide more general usage guidance draft-henrikson-sip-charging-information 1. Expert Review some review from SIP WG 2. No option tags, response codes, or methods OK 3. No overlap with planned/chartered extensions No overlap 4. Purely informational in nature OK 5. Does not undermine security ? 6. Clearly documented in RFC OK 7. Appropriate applicability statement Some good general guidance given, need to explain when NOT to use draft-henrikson-sip-orig-dialog-id 1. Expert Review some review from SIP WG 2. No option tags, response codes, or methods OK 3. No overlap with planned/chartered extensions significant overlap with SIP state, and cookies (chartered work) 4. Purely informational in nature Unclear. Appears to change algorithm used for SIP routing 5. Does not undermine security Unclear 6. Clearly documented in RFC Not yet 7. Appropriate applicability statement Needs to provide more general usage guidance draft-mills-sip-access-network-info 1. Expert Review some review from SIP WG 2. No option tags, response codes, or methods OK 3. No overlap with planned/chartered extensions No overlap 4. Purely informational in nature OK 5. Does not undermine security Some privacy concerns; generally well addressed in security section 6. Clearly documented in RFC OK 7. Appropriate applicability statement No applicability statement present draft-willis-sip-svcrtdisco 1. Expert Review good level of review from SIP WG 2. No option tags, response codes, or methods OK 3. No overlap with planned/chartered extensions No overlap 4. Purely informational in nature OK 5. Does not undermine security minor caveats addressed in security considerations 6. Clearly documented in RFC Yes 7. Appropriate applicability statement Some general guidance given, need to explain when NOT to use In addition there is an informational event package proposed... draft-beckmann-sip-reg-event 1. Expert Review some review in SIP, really needs review in SIMPLE 2. No template-packages OK 3. No overlap with planned/chartered extensions This appears to be a generically useful event package which should be addressed as a charter item in SIPPING Jonathan Rosenberg proposed such a document 4. Does not contradict normative behavior OK 5. Does not undermine security Mechanism introduces no new security concerns 6. Clearly documented in RFC Needs more detail - underspecified 7. Appropriate applicability statement No applicability statement present Probably not needed if this becomes a general purpose mechanism _______________________________________________ Sip mailing list https://www1.ietf.org/mailman/listinfo/sip This list is for NEW development of the core SIP Protocol Use sip-implementors@cs.columbia.edu for questions on current sip Use sipping@ietf.org for new developments on the application of sip
