摘要
为了给网络优化提供决策分析工具,根据影响网络生存性的要素建立数学模型,并在计算机上搭建了网络故障仿真与分析平台。通过对网络链路和节点故障的仿真,分析其对通信业务的影响,根据业务保护原则生成多种应对预案。通过预案的优化,在实际网络运行中最大限度地减轻了故障对业务的影响。研究表明,该平台能够准确有效地进行网络故障仿真与生存性分析,为光纤通信网络的业务保护和网络优化提供科学依据。
In order to provide decision analysis tool for network optimization,this paper established the mathematical model of network survivability based on the influences and realized the simulation and analysis platform for network failure. By simulating the optical network link or node failure to analyze the effect on different levels of network business,then generated scientific and effective contingency plan on the basis of business protection principles. Through the optimization of the plans,it reduced the influence of fault on the business to largest extent in the actual network operation. Studies show that this platform could accurately and effectively simulate network fault and analyze survivability,which provides scientific basis for business protection and network optimization in fiber communication network.
