摘　　要：光突发交换(OBS)被认为是下一代光网络中的有效核心交换技术之一,设计OBS网络的最初目的之一是减小突发包丢失率。解决突发竞争的方法主要包括光缓存、波长变换、偏射路由和突发分段。提出一种改进偏射路由方案,并建立了数学模型,对改进方案的性能进行了仿真分析,结果表明改进方案能更好的提高网络整体性能。Optical burst Switching （OBS）is considered as one of core technologies for next generation optical switching networks. The primary goal to design OBS network is to reduce burst loss probability. The main method to resolve contention is optical buffering, wavelength converter, deflection routing and burst segmentation in OBS. An improved deflection routing method is proposed and a mathematical model is developed. Simulation results show that the proposed scheme can effectively improve the burst loss performance of the entire networks.
