| 摘 要： | 论文提出了一种在WDM光网络中支持优先级的备用路由算法,该算法结合波长的使用情况,通过给优先级较高的光路建立请求预留较多的备用路由,从而降低了高优先级的光路连接的阻塞率。同时由于使用了备用路由,使较低优先级的光路建立请求性能得到优化。同现有的支持优先级的算法相比,该算法更多地考虑了路由问题,而且也增强了网络的抗毁性。计算机仿真结果表明,该算法在支持优先级的同时能有效降低网络各优先级光路的阻塞率。

| Abstract: | A novel priority-based alternate routing algorithm is proposed in this paper.By reserving more alternate routings for the request with higher priority,the blocking probability of which is guaranteed to be a lower degree,and at the same time ,the performance of lower priority request is improved.Compared with the existing algorithms based on priority,the problem of routing is paid more attention in this algorithm,with restoration of networks enhanced.Simulation results show that the algorithm can effectively reduce blocking probability of requests with different priorities. |
