摘　　要：对多厂商设备环境下SDH(synchronousdigitalhierarchy)传送网中的自动通道路由选择问题进行了讨论,提出了一种基于应用框架的简单有效的适配器设计方法:框架提供路由算法骨架,用适配器实现路由算法中因厂商设备与网管接口而异的特定步骤.相应地给出了一种子网内通道路由搜索算法,并可根据网络中已有资源和网管接口规则、有效地选择合适路由.应用上述方法和算法在实际网管系统中实现了自动通道路由选择功能.Issue of automatic channel routing in transport network under multi-vendor environment was analyzed for introduction of concise and effective design of adapter based on application framework pattern. The framework provides skeleton of the routing algorithm, whereas individual adapters focus on implementing key operations that are specific to different equipment types and associated management interfaces. A correlative channel routing algorithm within sub-network was discussed which could choose appropriate routes effectively according to the resources available in the network and rules defined by the management interfaces. Automatic channel routing functionality in network management system was implemented by leveraging the above-mentioned design and algorithm.
