摘要: 针对无线/有线混合网络中,无线误码丢包和网络拥塞丢包的区分问题,对丢失包对(Loss Pair)中探测包的ROD统计概率特性进行了分析,在此基础上提出了一种基于Fuzzy模式识别的丢包区分算法,仿真验证表明,该算法较当前主要TCP版本及典型区分算法具有更为理想的效果。

Abstract: Facing the problem of distinguishing wireless loss from congestion loss in hybrid wireless/wired networks, the ROD statistical probability characteristics of Loss Pair is analyzed. On this basis, a fuzzy pattern recognition based algorithm for loss differentiating is proposed. Simulation shows it performs better than the current main TCP mechanisms and the typical distinguishing algorithm.
