The IESG has approved the following document: - 'Application Layer Protocol Negotiation (ALPN) Labels for Session Traversal Utilities for NAT (STUN) Usages' (draft-ietf-tram-alpn-08.txt) as Informational RFC This document is the product of the TURN Revised and Modernized Working Group. The IESG contact persons are Spencer Dawkins and Martin Stiemerling. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-tram-alpn/ Technical Summary This document defines two APLN labels for two usages of STUN over (D)TLS: NAT discovery and TURN. Working Group Summary The draft was initially thought to be a "slam dunk" but the working group ended up arguing over the granularity of ALPN labels: did we need just one label for all of STUN or one label for each STUN usage? Once the WG selected the second option, it argued over the necessity of a generic "STUN" label for future and unknown usages, rejecting that idea in the end. Many TRAM regulars participated in the discussion. Martin Thompson in particular provided much (D)TLS and ALPN expertise. The consensus is solid and represents the whole working group. A discussion during Last Call resulted in the deletion of some non-normative text describing possible use cases. Document Quality No specific implementation was mentioned on the list, but this shepherd expects that WebRTC stacks and TURN servers will implement this draft quickly. Personnel The document shepherd is Simon Perreault <sperreault@jive.com> The responsible Area Director is Spencer Dawkins The IANA designated expert reviewer for Application-Layer Protocol Negotiation (ALPN) Protocol IDs is Joe Salowey
