QoS测量综述

A Survey on QoS Measurement

详细阐述了QoS测量的主要参数:包丢失率、吞吐量、延迟和延迟变化,并且比较了标准化组织ITU-T和I-ETF对这些参数定义的异同;然后分析了QoS测量的方法以及国内外相关领域的研究现状;最后总结了QoS测量的两类主要应用:网络性能评估和网络推测。

Firstly, this paper elaborates some primary parameters of QoS measurement, including packet loss, throughput, delay, delay variation, and compares the definition of QoS parameters by ITU-T with its by IETF. Sec-ondly, gives the class of QoS measurement and its research trend in the world. Lastly, it presents two primary appli-cations of QoS measurement: network performance evaluation and network inference.
