改进的高速长距离网络慢启动策略

Improved slow-start for high-speed long distance networks

分析了慢启动在高带宽时延积高速长距离网络中性能下降的原因,提出了一种改进的均滑式慢启动策略,该策略仅仅均匀了突发数据传输,没有破坏TCP的本质。NS仿真试验表明均滑式慢启动延迟了慢启动结束时间,获得了很好的最大窗口改善,在高带宽时延积网络中有效地改善了吞吐量性能。

This paper analyzes the performance degradation of normal slow-start in high-speed long distance networks.A smooth slow-start scheme is presented to solve this degradation.It smoothes network load and reduces probability of network congestion through control packets transmission by timer interrupt.NS simulation results show that smooth slow-start disperses burst packet transmission and improves the throughput performance.
