| 摘 要： | 在综合考虑光路径跳数、链路拥挤程度以及整个网络剩余资源对路由选择影响的基础上,提出了一种支持优先级的路由算法．该算法给较高优先级的链接请求安排较多的资源,从而降低高优先级的阻塞率,同时优化低优先级请求的阻塞率．计算机仿真结果表明,同传统的路由算法Fixed-Alternated Routing algorithm(FAR)相比,该算法在支持优先级路由的同时能有效降低网络各优先级的阻塞率．

| Abstract: | Synthetically considering the influences of optical path's hops,link's congestion and whole network idle resources,a priority-based routing algorithm is proposed.In the proposed algorithm,more resources are used for connect requests with higher priority,which reduces the blocking probability,and at the same time, blocking performance of the low prior requests is optimized.Computer simulation results show that compared with traditional algorithm of Fixed-Alternated Routing(FAR),the proposed algorithm can effectively reduce blocking probability of requests with different priority. |
