Traversal Using Relays around NAT Server Auto Discovery
RFC 8155, “Traversal Using Relays around NAT Server Auto Discovery”, is a Proposed Standard document published in April 2017 by P. Patil, T. Reddy, D. Wing. It updates RFC 5766. The canonical text is published by the RFC Editor.
Abstract
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.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
