Description of Working Group:

  Traversal Using Relays around NAT (TURN) was published as RFC 5766 in
  April 2010. For a few years, the protocol had seen rather limited
  deployment. This is largely because its primary use case is as one
  of the NAT traversal methods of the Interactive Connectivity
  Establishment (ICE) framework (RFC 5245), and ICE itself was slow
  to achieve widespread adoption, as other mechanisms were already
  being used by the VoIP industry. This situation has changed
  drastically as ICE, and consequently TURN, are mandatory to implement
  in WebRTC, a set of technologies developed at the IETF and W3C to
  standardize Real Time Communication on the Web.

  Together with the arrival of WebRTC, there is a renewed interest in
  TURN and ICE, as evidenced by recent work updating the ICE framework
  (still in progress), and standardizing the URIs used to access a STUN
  (RFC 7064) or TURN (RFC 7065) server.

  The goal of the TRAM Working Group is to consolidate the various
  initiatives to update TURN and STUN to make them more suitable for
  NAT traversal in a variety of environments, whether for realtime
  media establishment protocols such as the Offer-Answer Session
  Description Protocol (RFC 3264), XMPP (XEP-0176), RTSP
  (draft-ietf-mmusic-rtsp-nat), and RTCWeb (draft-ietf-rtcweb-jsep),
  or for non-realtime protocols such as HIP (RFC 5770) and RELOAD
  (RFC 6940). The work will include authentication mechanisms,
  a path MTU discovery mechanism, an IP address mobility solution for
  TURN, and extensions to TURN and STUN.  The Working Group will closely
  coordinate with the appropriate Working Groups, including ICE, RTCWEB,

  In developing upgrades to TURN, the group will consider the passive
  monitoring risks introduced by the centralization of call traffic
  through a TURN server. When such risks arise, they will recommend
  appropriate mitigations.  For example, a mechanism for directing traffic
  to a TURN server other than one configured by the application could be
  used to direct calls through a TURN server configured to do monitoring.
  When such a mechanism is used, it is important that the endpoints to the
  call apply end-to-end encryption and authentication to ensure that they
  are protected from the TURN server.

Goals and Milestones:

  Nov 2015 - Adopt TURN IP address mobility draft
  Jan 2016 - Send STUN-bis draft to IESG for publication as Proposed Standard
  Jan 2016 - Send TURN-bis draft to IESG for publication as Proposed Standard
  Mar 2016 - Send new authentication mechanism(s) to IESG for publication as Proposed Standard
