公平的多优先级WDM网络波长分配算法

为了支持不同的业务要求出现了支持多优先级的WDM网络波长分配算法 ,但是在支持多优先级的波长分配算法中仍然存在公平性问题。为此 ,该文在支持多优先级的分配限额波长分配算法的基础上令波长限额随连接距离而变化 ,提出了一种公平分配限额波长分配算法。仿真结果说明这种算法有效地改善了多优先级 WDM网络波长分配算法中不同距离连接间的阻塞率差别

Fair priority-based wavelength assignment method for WDM networks

Priority based wavelength assignment methods, such as the Assignment Quota Method, have been proposed to provide different blocking probabilities for traffic with different priorities. However, fairness is still an important issue in these methods. A new priority based wavelength assignment method named the Fair Assignment Quota Method was developed to improve the fairness by making the quota increase with distance. Simulation results illustrate that the new method has more balanced blocking probabilities for paths with different lengths.
