Study on a Priority Based Contention Resolution for Optical Burst Switching Networks

摘要

摘要: 该文提出一种解决光突发交换网络节点中突发数据包冲突的方法。发生冲突时，首先基于不同的优先级对突发数据包进行分割，然后根据这种分割方法提出了一种突发数据包的组合封装方式，最后利用计算机对其进行了模拟。可以看出这种方法对高优先级的突发数据包以及IP数据包有很好的保护作用，可以很好地实现服务质量QoS(Quality of Service)机制。

Abstract: A contention resolution method based on the priority of the bursts for optical switching networks is proposed in this paper. When the contention occur, firstly, the burst segmentation method is used on the bursts, secondly, based on the burst segment method a burst composite assembly technique is proposed, finally, the computer simulation is made to verify the result of the method, the fact that the method could commendably protect the high-priority bursts and IP packets could been clearly seen from the simulation, so that it could support good QoS for the networks.
