Google have just published two of their protocols JEP 0166 and JEP 0167 correspond respectively to Jingle Signalling and Jingle Audio protocols. Jingle aims to provide an extension to XMMP protocol allowing to intiate Audio, Video and others p2p multimedia sessions.
There exists no widely-adopted standard for initiating and managing peer-to-peer (p2p) multimedia interactions (such as voice and video exchanges) from within Jabber/XMPP clients. Although several large service providers and Jabber/XMPP clients have written and implemented their own proprietary XMPP extensions for p2p signalling (usually only for voice), those technologies are not open and do not always take into account requirements to interoperate with the Public Switched Telephone Network (PSTN) or emerging SIP-based Internet voice networks. By contrast, the only existing open protocol has been A Transport for Initiating and Negotiating Sessions (TINS) [1], which made it possible to initiate and manage p2p sessions, but which did not provide enough of the key signalling semantics to be easily implemented in Jabber/XMPP clients.
