摘要 光突发交换网络被认为是未来光网络发展的趋势,而突发包在节点的冲突问题却是光突发交换网络中一个非常需要解决的问题,目前很多情况下使用的光缓存技术虽然可以缓解冲突问题,但是却增加了节点结构的复杂性和噪声。论文首先提出一种基于优先级的冲突解决方法,并给出了突发包的封装格式,然后利用三种无缓存的冲突解决模型对不同优先级突发包的冲突问题进行了详细的叙述和比较。 Optical burst switched（OBS） network has been regarded as the trend of the next generation optical network, but the burst contention issue at the node is a very important question to be resolved.The optical buffer technique though could solve this problem slightly,it makes the node structure become more complex and could bring some noise. A priority based contending resolution has been proposed in this paper,and the burst assembly format has been given out,three bufferless contending resolution model also have been detailedly proposed and compared to analysis the different prioritized bursts in this paper.
