摘要
为了科学地评估网络运行情况,提出了网络质量的概念并阐述了其内涵;设计了一组反映网络质量的评估指标体系并以隶属度向量值计算指标的统计值,该值能够明确地反映在统计周期内指标的等级情况;基于模糊数学理论建立了采用统计的网络质量模糊评估模型。以4个不同驻地IP网络统计数据为例,对4个网络的质量进行了模糊评估,从而获得网络质量的量化评估结果。
The definition of network quality was presented and its connotation was expatiated for scientific evaluating network running status. The metrics were designed to reflect the network quality and the membership vector was used to compute its statistic values, the values can definitely reflect the metrics＇ ranks in the period of statistics. The network quality fuzzy evaluation model based on statistics was designed. The case study evaluated the four local IP networks＇ qualities based on their statistic values and got the quantitive evaluating results.
