在高带宽时延乘积网络中,现有TCP协议由于其使用的拥塞控制机制使得数据流长时间以低速率发送数据,不能有效利用网络带宽,造成带宽利用率随着带宽的增大而下降.对高带宽时延乘积网络中TCP的性能进行仿真,结果表明在该网络环境中使用TCP传输数据不能有效利用网络带宽.最后详细分析拥塞控制机制造成TCP使用带宽利用率低的原因.

Because of the congestion control, TCP will send the small data for a long time in High Bandwidth-Delay-Product Networks. So, TCP cannot use the bandwidth efficiently. And, the utilization rate will be decrease with the bandwidth increased. The simulation of the performance of TCP in High Bandwidth-Delay-Product Networks has show that TCP cannot use net?work bandwidth effectively. We analyze why congestion control influence TCP to use the bandwidth in the end.
