<title>Jingle ICE Transport Method</title>
<abstract>This specification defines a Jingle transport method that results in sending media data using datagram associations via the User Datagram Protocol (UDP) or using end-to-end connections via the Transport Control Protocol (TCP). This transport method is negotiated via the Interactive Connectivity Establishment (ICE) methodology (which provides robust NAT traversal for media traffic) and also supports the ability to exchange candidates throughout the life of the session, consistent with so-called "Trickle ICE" (draft-ietf-ice-trickle).</abstract>

<p>Depending on the application type, a user agent controlled by a human user might need to wait for the user to affirm a desire to proceed with the session before continuing. When the user agent has received such affirmation (or if the user agent can automatically proceed for any reason, e.g. because no human intervention is expected or because a human user has configured the user agent to automatically accept sessions with a given entity), it returns a Jingle session-accept message. This message MUST contain a &TRANSPORT; element qualified by the 'urn:xmpp:jingle:transports:ice:0' namespace, which SHOULD in turn contain one &CANDIDATE; element for each ICE candidate generated by or known to the responder, but MAY instead be empty (with each candidate to be sent as the payload of a transport-info message).</p>
