摘要
在高带宽延迟积网络中,传统TCP导致很低的网络效率。我们研究了窗口增量函数对网络稳定性和效率的作用,并提出TCPImpv拥塞控制。仿真结果表明,在高带宽延迟积网络中,TCPImpv的网络效率和分组丢弃性能明显优于HSTCP;在一般网络条件下,TCPImpv保持了传统TCP的性能。
The conventional TCP protocol leads to very low network efficiency in high bandwidth-delay-product networks.We have studied the impact of the congestion windows increment function on network stability and efficiency,and put forward TCPImpv control to improve the performance of TCP in high bandwidth-delay-product networks.Simulation results show that TCPImpv control has more network efficiency at the lower cost of packet loss than HSTCP.
