【摘要】 如何在光突发交换(OBS)网络中为承载的业务提供服务质量(QoS)保证,已经成为当前OBS领域的一个研究热点。从算法思想、QoS保证性能等方面,对当前几种主要的服务质量保证机制进行了研究:基于偏置时间的QoS机制、分段型QoS机制、比例型QoS机制、抢占式QoS机制、IPDiffServoverOBS的QoS机制以及基于数据信道分组的QoS机制。探讨了在设计一个有效的QoS保证机制时应考虑的因素以及今后的研究方向。更多还原

【Abstract】 How to efficiently provide QoS guarantee in optical burst switching (OBS) has become one of research focuses.Several QoS schemes are investigated,such as offset-time based,segmentation-based,proportional-based,preemptive,IP DiffServ over OBS and data channel scheduling,from the aspect of algorithm idea and performance of QoS guarantees.Based on the investigation,many issues that must be taken into considerations for an effective QoS mechanism are,and the research directions in QoS guarantee for OBS networks are also pointed out.更多还原
