Inter-arrival,Spike-train和Zigzag是在TCP接收端区分拥塞丢包和无线丢包的三种典型的隐式丢包检测技术。目前,对上述三种算法的性能分析是在不同的拓扑下进行仿真或测量,因此难有可比性。比较分析三种技术在同一拓扑下区分拥塞丢包和无线丢包的有效性,为隐式丢包检测技术的进一步研究与应用提供参考。仿真结果表明,三种技术效果均不太理想,总体来看,Spike—train要优于其他两种技术。
Inter-arrival, Spike-train and Zigzag are three typical schemes for differentiation of congestion losses and wireless losses on TCP receiver. The performance results above three schemes were obtained under different topology, so it is difficult to compare them. The aim is to compare and analyze above the schemes performance under the same topology . The results show that no single algorithm performs well across topologies and competition. However the Spike-train algorithm is better to the others, and all the algorithms have a shortcoming in common.
