The IESG has received a request from the INtermediary-safe SIP session ID WG (insipid) to consider the following document: - 'End-to-End Session Identification in IP-Based Multimedia Communication Networks' <draft-ietf-insipid-session-id-26.txt> as Proposed Standard This is a shortened second last call to consider a normative reference to an informational RFC that has been added as a result of comments from the initial last call. The referenced informational RFC is RFC7206 The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2016-08-18. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract This document describes an end-to-end Session Identifier for use in IP-based multimedia communication systems that enables endpoints, intermediary devices, and management systems to identify a session end-to-end, associate multiple endpoints with a given multipoint conference, track communication sessions when they are redirected, and associate one or more media flows with a given communication session. While the identifier is intended to work across multiple protocols, this document describes its usage in SIP. This document also describes a backwards compatibility mechanism for an existing session identifier implementation (RFC 7329) that is sufficiently different from the procedures defined in this document. This document obsoletes RFC 7329. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-insipid-session-id/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-insipid-session-id/ballot/ The following IPR Declarations may be related to this I-D: https://datatracker.ietf.org/ipr/1453/ https://datatracker.ietf.org/ipr/2160/ https://datatracker.ietf.org/ipr/2195/ https://datatracker.ietf.org/ipr/1716/ https://datatracker.ietf.org/ipr/2204/ https://datatracker.ietf.org/ipr/2205/ The document contains these normative downward references. See RFC 3967 for additional information: rfc7206: Requirements for an End-to-End Session Identification in IP-Based Multimedia Communication Networks (Informational - IETF stream) Note that some of these references may already be listed in the acceptable Downref Registry.
