IP网络性能指标体系的研究

The study of a framework for IP network performance metrics

网络性能指标是网络测评的基础。本文从网络测评的不同角度对IP网络的性能指标进行了综合分析,提出了一种能系统反映IP网络性能的指标体系,并给出了IP网络性能指标体系的形式描述。在此基础上引入了泛化指标和确定性指标的概念,探讨了确定性指标的内容及描述框架。该研究突破了目前IP网络性能指标体系研究的简单性、局限性,对IP网络测试和性能评价具有指导意义。

Network Performance Metrics are the basis of network measurement and evaluation. This paper analyses the performance metrics for IP network from different views of network measurement, proposes a framework for performance metrics which can present the performance metrics of IP network, and formalizes the framework for performance metrics. On the basis of which, the concepts of general metrics and definite metrics are defined, and the content and framework for definite metrics are discussed. This study break through the simplicity and limit for the present IP network performance metrics framework, and it is significant to IP network measurement and performance evaluation.
