The IESG has approved the following document: - 'Mobility with TURN' (draft-ietf-tram-turn-mobility-09.txt) as Proposed Standard This document is the product of the TURN Revised and Modernized Working Group. The IESG contact persons are Mirja Kühlewind and Spencer Dawkins. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-tram-turn-mobility/ Technical Summary The intent of this document is to define a mechanism for TURN allocations to survive a client IP address change. A new "mobility ticket" attribute allows the client to migrate to a new IP address using a make-before-break approach. The requested publication type is Proposed Standard because new TURN attributes and behavior are defined. Working Group Summary The draft was discussed actively in the MMUSIC working group, under the name MICE, before it was refocused and transferred to TRAM. Once in TRAM there were few iterations: the WG was roughly happy with the document as it was. A few good reviews were done by core WG members which resulted in small changes. Document Quality Interest in this document has been medium. The mechanism for TURN makes sense but there are a number of other layers in a SIP/WebRTC stack at which IP address mobility could be implemented, e.g., trickle ICE, re-INVITE, etc. At this moment there is no single agreed-upon "how IP address mobility shall be accomplished" vision and implementations have not yet picked a clear winner. Since the draft was first proposed in MMUSIC a sort of "wait and see" response had been slowing progress. Today it seems like there won't be a clear decision and the consensus is that publishing the TURN mechanism is what makes most sense at this point.
