    abstract =  {This document defines a solution for Network Address Translation (NAT) traversal for datagram based media streams setup and controlled with Real-time Streaming Protocol version 2 (RTSP 2.0). It uses Interactive Connectivity Establishment (ICE) adapted to use RTSP as a signalling channel, defining the necessary extra RTSP extensions and procedures.},
