Abstract
Streaming Media communications based on UDP are analyzed in this paper, one is based on Packet Loss Rate, and another is based on RTT (Round-trip Time), also an algorithm of adaptive one way delay congestion prediction (AAOWDCP) is proposed in the paper. AAOWDCP can shorten time interval of congestion feedback to the great extent and enhance real-time performance of congestion judgment. At last, a simulation of congestion controls, one is based on Packet Loss Rate and another is based on RTT (Round-trip Time), and the performance of AAOWDCP is carried out by using the NS simulator, the simulation validates the superiority of AAOWDCP. Index Terms--congestion control, RTT, real-time multimedia communication, AAOWDCP.
