摘    要:
光突发交换(OBS)是构造下一代全光网络的潜在技术之一,但存在网络参数设计困难和阻塞性能有限等问题。文章介绍了一种新型基于时隙的OBS网络体系,简要阐明了其各部分功能,并将其与常规OBS网络进行了对比。提出了网络节点中关键的时隙分配与调度问题,并给出相应的在线调度策略,仿真结果表明BF算法性能较优。

关 键 词:光突发交换  时隙  调度算法  路由与波长时隙分配  波分复用

Abstract:
Optical burst switching(OBS) is a potential technology to construct next generation all-optical networks,while its blocking performance becomes very poor in heavy load cases and network parameters are difficult to be designed.A novel time-slot optical burst switching networks architecture was intraduced in this paper.Based upon the comparison of conventional OBS networks,we present the mechanism of its control plane and corresponding functional units.The scheduling problem for network intermediate nodes was defined and slot assignment strategy was also discussed.Four on-line scheduling algorithms applied in network edge and core nodes are evaluated by simulation.
Keywords:optical burst switching(OBS)  time slot  scheduling algorithm  RWTA  WDM
