| 摘 要： | 提出了一种在光网络中实现流量工程的快捷的有带宽保证的负载均衡动态路由算法。该算法通过提出期望负载率的概念和新定义的链路关键度函数以及链路当前可用带宽确定链路动态成本，并依据该动态成本运用最短路径优先算法为到达的LSP请求建立动态成本优化路径。仿真实验表明，与其他算法相比，该算法在降低LSP建立请求服务拒绝率、均衡网络负载以及链路失效后重路由等方面有更好的性能。

| Abstract: | A swift dynamic routing algorithm in optical networks (SDRAO) with bandwidth guaranteed was proposed. The link cost was defined by the presented ration of expecting coad, the innovative function of link importance value and link residual bandwidth. A path was chosen through the shortest path algorithm based on link cost. Compared with other algorithms via simulation, the algorithm performances are better in decreasing refusing rate, balancing network load and rerouting after link failure. |
