libnice

The GLib ICE implementation

Libnice is an implementation of the IETF's Interactive Connectivity Establishment (ICE) standard (RFC 5245).

It provides a GLib-based library, libnice, as well as GStreamer elements.

ICE is useful for applications that want to establish peer-to-peer UDP data streams. It automates the process of traversing NATs and provides security against some attacks. It also allows applications to create reliable streams using a TCP over UDP layer.

Existing standards that use ICE include Session Initiation Protocol (SIP), XMPP Jingle and WebRTC.
