Wavelength conversion can eliminate the wavelength - continuity constraint and reduce the network blocking probability. Wavelength conversion is the key factor in minimizing the blocking probability and improving network performance in wavelength - routed all - optical networks. Spare wavelength converter placement is the key issue in all -optical networks. By analyzing every node with route amount through it, the route traffic , route length and centricity on routes, the paper proposes a heuristic wavelength converter allocation algorithms based on node's weight, and gives algorithms demonstration for general topology network .%波长转换技术可以消除全光网络中的波长一致性限制,降低网络阻塞率,因此在具有波长转换器的全光网中,如何通过合理配置、使用数量有限的波长转换器来最大程度的降低网络的阻塞率,这是全光网络需要解决的一个关键问题.因此对网络中通过节点的路由数量、通信量、路由长度及节点处于路由的中心距离进行分析,并给上述四个参数赋予一定的权重进行加权处理,提出了一种基于节点权的全光网络波长转换器配置算法,并针对一般拓扑网络进行了算法演示和分析.
