一种改进的IP承载网效能评估算法

An Effectiveness Evaluation Algorithm of IP Bearer Network

针对IP承载网络,提出一种效能评估算法,研究了IP承载网效能评估指标体系,包括时延、抖动、丢包率和吞吐量等方面,通过网管系统采集统计和性能测试仪spirent Testcenter探测2种方式进行参数获取,参数获取后,选择模糊综合评判法进行评估,重点研究了指标的无量纲化处理方法,通过分析标准值与指标原始值大小关系,抵消指标权重对综合评价值的影响。最后通过仿真IP承载网说明在特定应用场景下的效能评估。

For IP hearer network, this paper puts forward an algorithm of effectiveness evaluation, and studies the effectiveness evaluation indexes such as time delay, jitter and packet loss rate. The parameters are obtained through the collection and statistics of network management system and the detection of performance tester spirent Testcenter. After parameter obtained, the fuzzy comprehensive judgement is used for evaluation. This paper studies in detail the processing method of index non-dimension. The influence of index weight on comprehensive evaluation value is cancelled by analyzing the relation between standard value and original value. The effectiveness evaluation on IP bearer network is simulated in specific application scene.
