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 Internet Protocol 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 March 2008^[update], the proposed Jingle specification has not yet been approved by the XMPP Standards Foundation, but is considered for advancement to the next stage in the standards process. In June 2009, the Jingle website declares: "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. However, the version of the protocol implemented in libjingle differs from that published by the XMPP Software Foundation.
