TCP over OBS的性能分析及改进

Performance analysis and improvement of TCP over OBS

在光突发网络中,边缘路由器的FAP封装策略有减缓TCP流发送速率的趋势,这使得TCP流“相关受益”减小,导致其吞吐率也随之下降。对于这一问题,可以通过一种增大ACK封装时间的汇聚方案来解决。通过仿真验证,该方案的确大幅提高了TCP流的吞吐率。

In Optical Burst Switching（OBS） network, the FAP assembly strategy of edge router tends to slow down the sending rate of TCP traffic. As a result, the correlation gain of TCP traffic is reduced, which in turn makes the throughput drops down. There is a strategy to taelde this issue by increasing the ACK assembly time. Simulation results show that the strategy proposed here can signifieandy improve the performance of TCP over OBS in terms of throughput.
