摘要
光突发交换(OBS)是实现IP/DW DM网络的一种极有前途的方案.该文提出了一种用于OBS网络的PDF数据信道调度算法.此算法能支持比例区分服务,保证高优先级业务数据比低优先级业务数据得到更可靠的传输.计算机仿真验证了PDF调度算法的性能.
Optical Burst Switching （OBS）is a promising solution for realizing IP/DWDM. In this paper,a data channel scheduling algorithm called PDF is presented for OBS networks. This algorithm supports the proportional DiffServ in the OBS networks. Also the PDF algorithm can provide better transmission reliability for high priority data comparing than the low priority data in the OBS networks. Computer simulations are conducted to verify the performance of this algorithm.
