摘　　要：随着网络用户对网络的有效性要求越来越高,如何评估和量化分析网络有效性已经成为一个重要的研究课题。文章分析了自动交换光网络(ASON)一般的保护机制,并为每种保护机制提供了有效性分析的代数公式。用数例验证了该模型的正确性,分析了保护机制的有效性与相关网络参数之间的关系,并对各种保护机制的有效性进行了比较。As the demand of the network users for network availability is increasingly higher, to evaluate and quantify network availability has become a major research subject. This paper analyzes the general protection mechanisms for ASON and provides for each of them an algebraic formula for the availability analysis. It verifies the validity of the availability model by calculation examples, analyzes the relationship between the availability of the protection mechanisms and the relevant network parameters and makes comparisons between the availability degrees brought about by various protection mechanisms.
