摘　　要：文章提出了一种非循环的应用于光突发交换(OBS)网络的偏射路由算法.它基于各网络节点的路径度和平均跳转数来确定偏射路径.通过建立OBS网络仿真模型,从数据突发的丢失率、平均跳转次数和端到端延时等方面来对其进行评价.仿真结果表明,该算法能确定有效的非循环偏射路径,为OBS网络提供了公平的网络资源利用.In this paper, we propose the acyclic deflection routing (ADR) algorithm for OBS networks. The main idea of the ADR algorithm is to determine the deflection paths based on the pathdegree and the average hop distance of nodes. A network simulation model is developed to evaluate the ADR algorithm in terms of data burst loss probability, average hop distance, and endtoend delay. Simulation results show that the proposed algorithm can determine efficient loopless deflection paths and provide the fair utilization of network resources for OBS networks.
