Abstract
Some high-speed protocols such as HSTCP have been proposed to improve the ability of bandwidth utilization in high-speed networks. However, the increased scalability of high-speed TCP leads to many dropped packets in a single loss event in drop tail environment. In addition, there exists burstiness on short time scales that may cause lots of packets loss. In this paper, we analyze the problem of packet loss, and then propose ACWAP (Adaptive Congestion Window Adjustment plus Pacing) algorithm to reduce the loss rate of high-speed TCP. Along with pacing algorithm for avoiding burstiness on short time scales, ACWAP uses delay information to estimate the network state and adaptively changes the increase parameter to 1 before congestion to reduce the number of dropped packets. Many simulation results show our proposed algorithm can reduce the number of dropped packets in a single loss event, alleviate synchronized loss phenomena and improve the RTT unfairness while keeping the advantages of high-speed TCP.
