通信网络抗毁性量度研究

Study on measures of communication network invulnerability

通信网络发生故障时,常常会导致网络中传输业务受到影响,从而带来各方面的损失,为了避免这样的损失,在网络设计阶段就要把网络抗毁性作为一个必须考虑的重要因素,分析了网络抗毁性的定义、影响因素,介绍了两种提高传输业务的抗毁性的常用方法,并引入相应的量度系数,以便精确地衡量网络抗毁性的高低,且讨论了把抗毁性量度系数用于网络优化的方法。

When a malfunction occurs in communication network, usually it causes transmission broken, and costs a lot on many sides. In order to avoid this kind of malfunction, the improvement of network invulnerability should he considered during network designing. This paper analyzes the definition and affecting factor network invulnerability. Two different ways are presented to im- prove network invulnerability. And for the purpose of scaling of network invulnerability, two measuring factors are given according to the improvement. Besides that, the using of network invulnerability factor to be used in network optimization is discussed.
