| 摘 要： | 已有研究表明时隙光突发交换(TS-OBS)网络与常规OBS网络的性能基本一致.因此,在TS-OBS网络中有效地支持QoS(Quality of Service)是一个很重要的问题.文章从时隙分集出发,提出了一种适合TS-OBS网络的QoS算法,这种算法可以根据各个优先级业务变化情况,动态地调整各个优先级业务使用的时隙数目,能够在提供区分服务的同时更有效提高信道的利用率并降低网络的阻塞率.

| Abstract: | The current research indicates that the TS-OBS network has the same performance as traditional OBS network. The TS-OBS network would become an important aspect for construction of all-optical network. Accordingly, QoS in TS-OBS network is an important issue. Based on time-slot diversity, a new algorithm is proposed in this article. It can dynamically adjust the numbers of the time-slots for various priorities to improve the utilization ratio of the channels and decrease blocking in the network, being determ... |
