Traversal Using Relays around NAT (TURN) [RFC5766] is a protocol that is often used to improve the connectivity of Peer-to-Peer (P2P) applications (as defined in Section 2.7 of [RFC5128]). TURN allows a connection to be established when one or both sides are incapable of a direct P2P connection. The TURN server is also a building block to support interactive, real-time communication using audio, video, collaboration, games, etc., between two peer web browsers using the Web Real-Time Communication (WebRTC) [WebRTC-Overview] framework.
