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QoS,并通过仿真分析了其在优化OBS网络中的性能.

A significant issue in optical burst switching (OBS) networks is contention resolution[1,2]. Deflection routing is one of contention resolution mechanisms in optical networks. This paper proposes an acyclic deflection routing (ADR) algorithm for OBS networks. The main idea of ADR algorithm is to determine the deflection ports based on the path-degree of nodes. ADR algorithm supports the ordered transmission of burst data and distributes the traffic of deflection paths among intermediate nodes with low path-degree. We also consider supporting QoS and propose the routing scheme for service differentiation, and investigate the performance of it in prioritized OBS networks through simulation.
