Jingle (protocol)

Proposed Jingle logo

Jingle is an extension to the Extensible Messaging and Presence Protocol (XMPP). It implements peer-to-peer (P2P) session control (signaling) for multimedia interactions such as in Voice over IP (VoIP) or videoconferencing communications. It was designed by Google and the XMPP Standards Foundation. The multimedia streams are delivered using the Real-time Transport Protocol (RTP). If needed, NAT traversal is assisted using Interactive Connectivity Establishment (ICE).

As of December 2009, the proposed Jingle specification has not yet been approved by the XMPP Standards Foundation, but is now a Draft Standard, meaning: "Implementations are encouraged and the protocol is appropriate for deployment in production systems, but some changes to the protocol are possible before it becomes a Final Standard."

The libjingle library, used by Google Talk to implement Jingle, has been released to the public under a BSD license. It implements both the current standard protocol and the older, pre-standard version.
