   <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>
