| 摘 要： | 光同步数字系列（ＳＤＨ）在通信中的广泛应用给通信网的设计提出了新的要求。以边失效作为网络失效源，失效发生时网中尚存的业务量作为网络的生存性测度建立了网络的生存性模型，对３种典型的网络拓扑，即环型、线型和星型网络的生存性进行了分析。同时用该模型分析了网络生存性与业务模型的关系。

| Abstract: | Deployment of Synchronous Digital Hierarchy(SDH) in communication network introduces some new problems for network planning.We establish the survivability model through considering the link failures and have carried out survivability analysis with this model for three different topological network, ring, line and star.The survivability of network is characterized with traffic ratio existing in the network when the failures happen.The dependent of survivability on traffic patterns is analyzed. |

| Keywords: | network structures synchronized optical networks traffic pattern |
