TURN [RFC5766] is a protocol that is often used to improve the connectivity of Peer-to-Peer (P2P) applications (as defined in Section 2.7 of [RFC5128]). TURN allows a connection to be established when one or both sides are incapable of a direct P2P connection. It is an important building block for interactive, real- time communication using audio, video, collaboration, etc.

      Traversal Using Relays around NAT (TURN) Server Auto Discovery


   Current Traversal Using Relays around NAT (TURN) server discovery    mechanisms are relatively static and limited to explicit    configuration.  These are usually under the administrative control of    the application or TURN service provider, and not the enterprise,    ISP, or the network in which the client is located.  Enterprises and    ISPs wishing to provide their own TURN servers need auto-discovery    mechanisms that a TURN client could use with minimal or no    configuration.  This document describes three such mechanisms for    TURN server discovery.

   This document updates RFC 5766 to relax the requirement for mutual    authentication in certain cases.
