摘　　要：基于HSTCP和二项式拥塞控制协议(BCCP),提出一种新的适用于在高速网络环境下传输流媒体数据的速率控制协议高速二项式协议(HSBCCP).介绍了HSTCP和BCCP,分析了其在高速带宽延迟网络下传输流媒体数据的缺陷;并从HSBCCP与TCP以及HSTCP的拥塞窗口比较,HSB-CCP与TCP的链路利用率比较,以及HSBCCP与其他现有高速拥塞控制协议的链路利用率、平滑性以及网络自适应性等多方面作了性能分析.结果表明:HSBCCP具有较高的链路利用率,良好的速率平滑性和网络自适应性,有效地克服了TCP在高速网络中链路利用率不足的问题和HSTCP速率振荡过大的问题.Based on HSTCP and binomial congestion control protocol （BCCP）,a new high speed congestion control protocol was proposed. This protocol,named as high speed binomial congestion control protocol （HSBCCP）,is adequate for transmission of streaming media data in high speed network. HSTCP protocol and BCCP protocol were introduced,and their default for transmission of streaming media data in high bandwidth delay environment was analyzed. Performance comparisons of HSBCCP and other congestion control protocols were completed from different aspects including congestion window,link utilization,rate smoothness and network adapting. Simulation results show that HSBCCP has high link utilization,favorable rate smoothness and network adaptivity. There are no problems of low link utilization of TCP and high rate oscillation of HSTCP in HSBCCP.
