| 摘 要： | 为了保证光突发交换(OBS)网络中不同优先级业务的服务质量(Qos)和有效地降低突发包的丢失率,提出了一种基于优先级与突发包分割的光缓存方法.该方法通过在输出数据信道上设置光纤延迟线组来缓存被分割的冲突突发包.当冲突发生时,基于突发包的优先级进行"竞争突发包头部分割或者原突发包尾部分割,,处理;无冲突部分进行交换或者直...

| Abstract: | In order to guarantee quality of service(QoS) of different priority bursts and effectively reduce the burst loss probability(BLP),an optical buffer mechanism based on priority and burst segmentation in optical burst switching(OBS) networks is proposed.It intercalates the fiber delay units to buffer the segmentation part of bursts in the output data channels.When competition occurs,the header of competition burst data packet or the tail of original burst data packet is segmented according to the priority of ... |
