Traversal Using Relays around NAT (TURN) was published as RFC 5766 in 
April 2010. Until recently 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 
the WebRTC environment. The work will include the addition of DTLS 
as an additional transport, authentication mechanisms, and extensions 
to TURN and STUN. The Working Group will closely coordinate with the 
appropriate Working Groups, including RTCWEB, MMUSIC, and HTTPBIS.
