摘要
IP网络自身不能为终端用户提供关于网络的负载和容量的信息反馈。终端用户为了了解上述信息,可以采用主动的端到端测量方式,来对网络路径或链路的带宽特性进行估计和测量。回顾了带宽测量领域的最新成果,包括相关测度的定义,测量的算法,对每种算法的原理做了详细的介绍,并指出了各种算法的特色和缺陷。
IP networks do not provide explicit feedback to end hosts regarding the load or capacity of the network. Instead, hosts use active end-to-end measurements in an attempt to estimate the bandwidth characteristics of paths they use. This article reviews the state of the art in bandwidth measurement techniques, including metrics and methodologies employed. The principle of each methodology is introduced in detail, as well as its features and limitation.
