摘要
基于WDM EPON系统结构和已有波长带宽分配算法(DWBA)的不足,提出了一种结合流量预测与预分配机制的动态波长带宽分配算法——DWBPA。仿真表明在不同网络负载情况下,该算法不仅保证了波长带宽分配的公平性,而且能够满足高优先级业务的延时要求。
Based on the WDM EPON system architecture and some previous algorithms, the paper presented a novel dynamic wavelength and bandwidth allocation algorithm that supports traffic estimation and bandwidth pre-allocation. Under different network loads, the simulation results show that the algorithm provides a good firmness performance and can meet the delay demands of high priority services.
