指出了光突发交换 (OBS)网络的一个关键问题是如何解决资源冲突 ,偏射路由是光网络中的冲突解决机制之一 .提出了 OBS网络非循环偏射路由算法 (ADR) ,此算法基于各网络节点的路径度来确定路由中的偏射路径 ,支持突发数据的有序传输 ,将偏射路径的流量分布到具有低路径度的中间节点 .利用此算法实现了区别服务以支持 Qo S,并通过仿真分析了其在优化 OBS网络中的性能 .
It is pointed out that one of the key problems of Optical Burst Switching (OBS) network is how to solve the resource conflict, and one of the mechanisms for resolving collisions in optical networks is polarization error routing (OBS). A non-cyclic Orthogonal Routing Algorithm (ADR) Based on the path degree of each network node to determine the path of the deflection in the route to support the orderly transmission of the burst data to distribute the traffic of the path to the intermediate nodes with a low degree of path.By using this algorithm to achieve differentiated services to support Qo S, and through the simulation analysis of its performance in optimizing OBS network.
