1 Introduction


This protocol specifies proprietary extensions to the Traversal Using Relay NAT (TURN) protocol. TURN is an Internet Engineering Task Force (IETF) draft proposal designed to provide a mechanism to enable a user behind a network address translation (NAT) to acquire a transport address from a public server and to use the allocated transport address to receive data from a selected peer.

This protocol is used as part of the Interactive Connectivity Establishment (ICE) Extensions protocol, as described in [MS-ICE] and [MS-ICE2].

Sections 1.5, 1.8, 1.9, 2, and 3 of this specification are normative. All other sections and examples in this specification are informative.
