OBS 网络支持优先级的分割及光缓存方法研究
Research on priority supported burst segmentation and optical buffering in OBS networks
摘要
Abstract
In order to effectively reduce the burst loss probability of Optical Burst Switching (OBS)networks,the existing opti-cal buffering schemes based on priority and burst segmentation are studied and improved in the case of multi-wavelength chan-nels.In the improved scheme combined with the priority and burst segmentation mechanism,a cross-type optical buffer struc-ture is introduced to buffer the segmented bursts and also the judgment of the idle channels and optical buffer delay time to en-sure lower packet loss rate.The simulation results show that this scheme can effectively reduce the packet loss rate and guaran-tee the QoS of different priorities in OBS networks,thus improving the performance of the entire network.关键词
