| 摘 要： | 提出了一种应用于部分共享波长转换（PWC）的波长路由光网络（WRON）中的基于节点阻塞的动态路由算法，它不需要共享复杂的波长转换信息，而是将各节点的阻塞特性考虑到路由过程中。为评价算法性能，在14节点的国家科学基金网（NSFNET）拓扑中进行了仿真。结果表明，新的路由算法显著改善了网络的阻塞性能和建路失败的概率，尤其是随着网络负载的降低，网络性能的改善更显著。

| Abstract: | A new dynamic routing algorithm based on the blocking nodes was presented for the wavelength routing optical networks(WRON) consisting of partial-shared wavelength converter(PWC).Instead of sharing the complicated information of wavelength converting,it takes the blocking characteristics of each node into consideration in the routing process.To estimate the algorithm,we do the emulation in the 14-nodes national science fund network(NSFNET).The result shows that the performance of the blocking probability as well as the probability of setting up failure has been improved greatly and can be improved even greater when the network is in low load. |
