| 摘 要： | 提出一种解决光突发交换(OBS)网络节点中突发数据包冲突的方案.发生冲突时,在OBS层重传被丢弃突发数据包,然后给出评估这种重传机制丢包率的方法,并与偏射路由策略的性能进行比较,结果表明突发重传机制显著改善了丢包率.可以很好地实现服务质量(QoS)机制.

| Abstract: | A resolution for solving burst contention in OBS network nodes is proposed. When contention occurred, the lost bursts are retransmitted at the OBS layer, then the method for evaluating the burst loss probability of this retransmission strategy is given, and through the comparison with deflection routing strategy the results show that the burst retransmission strategy can significantly improve the burst loss probability, so that the QoS mechanism can be well realized. |
