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,提出一种能系统反映IP网络性能的指标体系。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 index is the basis of network evaluation. This paper analyzes the performance of IP network from different aspects of network evaluation, and proposes an index system that can reflect the performance of IP network systematically. On this basis, the concept of generalization index and deterministic index is introduced, and the content and description framework of certainty index are discussed. This research has broken through the simplicity and limitation of the research on IP network performance index system and has guiding significance for IP network testing and performance evaluation.
