摘要 Westwood是基于测量的增强算法,采用ACK估计可用带宽。基于SCTP的CMT采用激进的Reno拥塞窗口更新机制,导致频繁的发生重传。通过对CMT重传机制和拥塞窗口更新机制的研究,结合Westwood算法,提出了一种在CMT中预测网络拥塞状况,合理更新拥塞窗口,使CMT在瓶颈带宽上有效传输数据。通过NS2仿真证明,该策略在吞吐量和丢包率方面有一定改进。 Westwood is an enhancement algorithms using the ACK estimated available bandwidth. CMT uses the radical Reno mechanism to update congestion window control, and it leads to frequently retransmit the packets. Based on the study of CMT retransmission mechanism and cwnd update policy, a new policy, which can estimate the bandwidth, update the congestion window and transmit the data packets efficiently on bottleneck bandwidth. The improvements of the throughput and packet loss rate are showed by NS2 simulation.
