Abstract: After studying the stream media congestion question, the network adaptive transmission control and the transmission characteristic of RTP protocol, this paper proposes a kind of network adaptive transmission control strategy based on the bandwidth and expatiates this transmission strategy control mechanism. According to network resource condition, this strategy adjusts dynamically transmission speed to match the network bandwidth change, and achieves network adaptive transmission.

Key words: Real-time transport protocol(RTP), Real-time transport control protoco1(RTCP), Network state estimate, Adaptive transmission control strategy
