摘　　要：光传输网络的突出优势就是组网,自愈环是其主要拓扑结构,网络具有自愈保护功能。本地传输网络一般按骨干层、汇聚层和接入层的功能结构组织,在层次网络结构中,如何组织光缆路由。本文利用分枝限界法解决了自愈环光缆路由的选择问题,提出了分层网络光缆路由规划的数学模型。The advantage of optical transmission system is to form networks. Self-healing ring is the main topology architecture. The local transmission network consists of backbone convergence and access three layers. This paper discusses the problem of choosing optical cable route with branch and bound way and puts forward the model of planning route in Layered network.
