Application programs at the source end format payload data into RTP packets using RTP specifications and dispatch them using unreliable UDP along a single path. Multipath transport is an important way to improve the efficiency of data delivery. In order to apply the framework of multipath transport system based on application-level relay (MPTS-AR) to RTP-based multimedia applications, this document defines a multipath real-time transport protocol based on application-level relay (MPRTP-AR), which is a concrete application-specific multipath transport protocol (MPTP). Packet formats and packet types of MPRTP-AR follow the common rules specified in MPTP profile. Based on MPRTP-AR, RTP-based multimedia applications can make full use of the advantages brought by MPTS-AR.}, }
