通信网链路重要性的评估是通信网系统可靠性研究的问题之一。如何有效地评估通信网链路的重要性，有着十分广泛的实际意义。本文首先介绍了通信网链路重要性的评估模型。然后基于该评估模型介绍了三种评估链路重要性的方法：最小路集——割集法，可靠性多项式法和业务量损失法。并比较了这三种方法的优劣，举例说明了这三种方法的运用。这些方法可用于通信网的设计或提高通信网的可靠性。
The evaluation of the importance of communication network links is one of the problems in the study of the reliability of communication network systems. How to effectively evaluate the importance of communication network links has a very wide range of practical significance. This article first introduces the importance of communication network link evaluation model. Then based on the evaluation model, three methods to evaluate the importance of the link are introduced: the minimum set-cut set method, the reliability polynomial method and the traffic loss method. And compares the merits and demerits of these three methods, exemplifies the application of these three methods. These methods can be used for the design of communication networks or to improve the reliability of communication networks.
