Interactive Connectivity Establishment : A Protocol for Network Address Translator Traversal for Offer/Answer Protocols
RFC 5245, “Interactive Connectivity Establishment : A Protocol for Network Address Translator Traversal for Offer/Answer Protocols”, is a Proposed Standard document published in April 2010 by J. Rosenberg. It obsoletes RFC 4091, RFC 4092. It has since been updated by RFC 6336. It has been obsoleted by RFC 8445, RFC 8839 — refer to the newer document for the authoritative version. The canonical text is published by the RFC Editor.
Abstract
This document describes a protocol for Network Address Translator (NAT) traversal for UDP-based multimedia sessions established with the offer/answer model. This protocol is called Interactive Connectivity Establishment (ICE). ICE makes use of the Session Traversal Utilities for NAT (STUN) protocol and its extension, Traversal Using Relay NAT (TURN). ICE can be used by any protocol utilizing the offer/answer model, such as the Session Initiation Protocol (SIP). [STANDARDS-TRACK]
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.
