摘要 研究了建立在经典服务质量QoS(QualityofService)基础上的比例QoS方案 ,并以此为理论依据 ,分析了主动丢弃算法在OBS(OpticalBurstSwitching)网络中支持比例QoS存在的问题 .针对这些问题 ,提出了光突发交换 成比例丢失率OBS PLR(OpticalBurstSwitching ProportionalLossRate)丢弃算法 ,以实现突发数据丢失率的可控、成比例 ,且不至于偏大 . Proportional Quality of Service(QoS)scheme is studied based on classical QoS. Regarding it as theoretical foundation, the problems in using Intentional Burst Dropper to support Proportional QoS in Optical Burst Switching(OBS)networks are analyzed. Optical Burst Switching-Proportional Loss Rate(OBS-PLR)Burst Dropper which can achieve controllable, proportional, and lower burst loss probability is proposed to solve these problems. Both theoretical analysis and simulation results demonstrate the improved performance of Proportional QoS control.
