WDM光网络中固定路由的优化算法

An optimal fixed routing algorithm for WDM optical networks

通过研究WDM光网络中固定路由策略的选取对网络性能的影响,提出了一种新的用于优化固定路由的算法——综合代价法。该算法综合考虑了链路负载和路由跳数这两个因素,以综合代价为策略进行路由优化。计算机仿真结果表明,针对不同的网络负载情况,综合代价法能够有效地降低网络的阻塞率,提高网络的性能。

The different fixed routing algorithms for WDM optical networks are described. Because link load and route hops both affect network performance, author propose a new optimal algorithm—— Integrate-Cost Algorithm. The algorithm gets optimal route according to integrate-cost, taking into account both link load and route hops. The results of simulation show that the algorithm can reduce probability of block and improve network performance according to the load of networks.
