| 摘 要： | 在分析网络可用带宽测量算法性能及存在问题的基础上,提出一种轻负载、高精度、自适应的端到端可用带宽测量算法iChirp。基于自拥塞理论采用近似指数分布的动态探测队列结构,以可用带宽预测值为中心设置关键域,在其中加快采样频率,增加报文密度,并能根据反馈自适应的对探测范围和关键域进行调整。仿真实验结果表明,该算法对网络干扰性较小,能够快速准确地测量出端对端可用带宽。

| Abstract: | After analyzing the performance and problems of network available bandwidth estimation algorithms,iChirp,a light overhead,high accuracy,self adaptive end to end available bandwidth estimation algorithm is presented.Based on the concept of self-induced congestion,iChirp features a dynamic approximate exponential flight pattern of probes.The probing stream consists of a critical region around the predictive value of available bandwidth,where the probing rates are sampled more frequently and the density of pro... |
