Hi, I have reviewed draft-ietf-tsvwg-sctp-failover-14 as part of the Operational directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written with the intent of improving the operational aspects of the IETF drafts. Comments that are not addressed in last call may be included in AD reviews during the IESG review. Document editors and WG chairs should treat these comments just like any other last call comments. I believe the document is 'Ready' for publication. I appreciate the clear writing style. Some comments follows: - Should this I-D have an Updates: 4960 header to indicate that it updates RFC 4960? The abstract says: The procedures defined in the document require only minimal modifications to the RFC4960 specification. - Since the I-D introduces the new state Potentially Failed, does this imply that an update of the SCTP-MIB [RFC3873] (sctpAssocState) is needed as well? Are there additional MIB objects to report, e.g., spt_pathpfthld and spt_pathcpthld? I see some additional SCTP related docs in TSVWG and perhaps after they have been completed an update of the SCTP-MIB would make sense to consider. - s/Tel co signaling environments/telephony signaling environments/ /js -- Juergen Schoenwaelder Jacobs University Bremen gGmbH Phone: +49 421 200 3587 Campus Ring 1 | 28759 Bremen | Germany Fax: +49 421 200 3103 < http://www.jacobs-university.de/ >
