A new IETF non-working group email list has been created. List address: ice@ietf.org Archive: https://mailarchive.ietf.org/arch/search/?email_list=ice To subscribe: https://www.ietf.org/mailman/listinfo/ice Purpose: Interactive Connectivity Establishment (ICE) is at the same time a NAT traversal technique, a multihomed address selection technique, and a dual stack address selection technique that works by including a multiplicity of IP addresses and ports in both the request and response messages of a connectivity establishment transaction. The IP addresses and ports provided by each side are paired and tested by peer-to-peer connectivity checks until one of these pair is selected to transport data. ICE was originally defined for the Offer-Answer (RFC 3264) protocol used by SIP and later XMPP, RTCWeb and other realtime media establishment protocol. But it is also used by HIP and RELOAD.
