部分波长光网络中的动态波长分配算法

为适应网络中不同服务质量（QoS）的光路建立请求具有不同的优先级的情况，提出了一种用于部分波长可变网络中支持QoS的动态波长分配算法。该算法对网络中的业务请求分高、低两个优先级进行处理。对于高优先级的光路建立请求，通过充分利用网络中已配置的波长转换器实时改变可用波长集，以降低高优先级业务请求的阻塞率。对低优先级的光路建立请求，只考虑所选路径的当前位置是否有波长转换器来改变可用波长集，保证了低优先级的光路建立请求速度。仿真结果表明，该算法既能保证较高优先级的光路建立请求具有较低的阻塞率，又充分利用了有限的网络资源，实现了对波长转换器的最优利用。

Dynamic wavelength assignment algorithm in all-optical networks with partial wavelength

A dynamic wavelength assignment algorithm in All-optical Networks with partial wavelength conversion is proposed, for adapting the demand of different business for asking the grade of corresponding different Quality of Service Requests. This algorithm processed the service requested which was divided into high and low two priorities requests, regarding the high priority request through full using the wavelength converter which was already disposed in the network for changing the applicable wavelength collection at the real-time to reduce blocking rate which the high priority service requested. To the low priority path of rays establishment request, only considered chooses the way the current position whether does have the wavelength converter to change the applicable wave length collection, has guaranteed the establishment request speed of the low priority request. By using the algorithm, the blocking rate of the high priority request is guaranteed to be a lower degree, and moreover fully used the limited network resources. Realized superiorly uses to wavelength conversion. In the article produced the computer simulation result.
