Abstract: The methods of building and applying multipath for transmission become the hot spot of current network control protocol research. There is no perfect solution for real-time media data multipath transmission control protocol. In order to tackle the problems in the practical situations, a new relay-based end-to-end multipath transmission control protocol based on relay was proposed in the paper. In the protocol, the relay is used as the important component to build and manage multipaths. The format of message and the results of simulation test related to the protocal are presented in detail. The simulation results show that when the protocol is used to transmit real-time audio and video media data, compared with single-path transmission protocal, the transmission delay, data loss rate and transmission quality are improved significantly.

Key words: relay, end-to-end, multipath, transmission control protocol(TCP), real-time
