Multipath RTP based on RTP Relay Application (MPRTP-RA)
Shaowei Liu, Wei Zhang, Weimin Lei · 2013
This document defines the framework of multipath transmission of real- time media based on relay. The framework allows participants to use multiple paths,including the default IP path and relay paths, to transport media in a RTP session. A relay path may via one or more RTP relay nodes which provide relay services for media data. This framework describes function blocks and behaviors of MPRTP-RA-capable RTP agent and RTP relay. The framework also defines multipath transport protocol by extending RTP, and relay control protocol named OpenPath.
