ANP网络可用性层次化模型评估方法

Evaluation Method of Hierarchical Network Availability Model Based on ANP

随着网络规模异构化和复杂化的日益加剧,对网络可用性分析的难度不断加大,需要向综合化、多元化和开放扩展的方向发展,文中提出了一种基于网络分析方法的网络可用性层次化模型评估方法,该方法从系统全局角度自底向上定义了设备、链路和业务的可用性三层模型,并采用层次化分析的递进方法对网络可用性进行定量分析研究。通过仿真实验数据说明层次化模型评估方法在有效性和准确性,均取得良好的评估效果,验证了评估方法能够根据网络层次结构全面、客观地对网络可用性进行评价分析,解决复杂网络可用性问题。

With the increasing isomerization and complexity of network,it is more and more difficult to analyze network availability.Therefore,integrated,diversified and expanded methods need to be developed.This paper presents a model for evaluating hierarchical network availability based on Analytic Network Process.By this method,the three-tier availability model of the equipment,links and services is defined from the perspective of the overall system,and the hierarchical progressive method is used to quantitatively analyze network availability.The simulation experiment shows that the evaluation method is effective and accurate and can comprehensively and objectively evaluate the complex network availability according to the network hierarchy.
