摘　　要：为了克服光突发交换网络的路由冲突对传送成功率的影响,需要设计网络冲突解决机制。提出一种基于平均传递概率预测的光突发交换网络路由算法,采用跨层确认机制进行网络冲突协调。首先采用分布式跨层链路机制构建光突发交换网络的信道模型,计算得到光突发交换网络的传递预测概率值。然后采用负载均衡的自适应分层路由探测方法进行网络冲突检测,通过平均传递概率预测进行冲突信息疏导,实现网络冲突解决机制优化。最后进行仿真分析,结果表明,采用该方法进行光突发交换网络路由设计,有效解决了网络冲突问题,提高了网络传递成功轮数,降低了死亡节点数量,计算开销较小,网络的生存周期得到提高。In order to overcome the influence of optical burst switching network routing conflict on the transfer of the success rate of the network,need to design a mechanism for resolving conflicts. This paper proposes an optical burst switching（ OBS） network routing algorithm based on the prediction of average delivery probability,which uses the cross layer network conflict coordination mechanism. Firstly,the channel model of optical burst switching network is constructed by using the distributed cross layer link mechanism,and the predicted probability value of the optical burst switching network is calculated. Then the load balancing adaptive hierarchical routing detection method is used to detect the conflict of the network,and the conflict information is optimized by the average transmission probability prediction. Finally,the simulation results show that using this method can effectively solve the conflict problem,improve network transmission successful round number and reduce the death number of nodes. It has small calculation overhead and network lifetime is improved.
