| 摘 要： | 提出一种协同工作式的TCP(transmission controlprotocol)拥塞控制改进协议C3P(cooperant congestion control protocol),通过C3P源端检测RTT(roundtri ptime)延时信息和路由器反馈的1bit显式预测信息来判断网络拥塞状态,自适应地调节拥塞窗口.仿真实验表明,C3P协议能够有效地适应这种高带宽延时网络的传输特性,以保证网络获得更优的链路利用率、TCP友好性以及流与流之间的公平性.

| Abstract: | This paper presents a Cooperant Congestion Control Protocol (C3P) that uses 1 bit routers' explicit feedback predicted information and delay signals to adjust the congestion windows appropriately. Simulation results show that C3P can efficiently improve the bandwidth utilization, TCP (transmission control protocol)-friendliness, RTT (round trip time) fairness and reduce the packet drop rate in High Bandwidth-Delay Product Networks. |
