Routing conflict coordination mechanism for multi mode optical fiber network communication

多模光纤网络由于用户终端之间带宽差异性容易导致路由冲突,为了提高网络的连通性和通信信道的均衡性,提出一种基于节点覆盖区域自适应任务调度和通信信道均衡调制的多模光纤网络通信的路由冲突协调机制,首先构建多模光纤网络的通信信道模型,采用分布式网络分簇协议进行路由探测模型设计,计算多模光纤网络的路由冲突置信概率,然后提取多模光纤网络通信信道的节点覆盖区域的能量谱特征,根据能量谱特征进行自适应任务调度,结合通信信道均衡调制方法实现路由冲突规避。最后进行网络组网分析和实验测试,结果表明,采用该方法进行多模光纤网络通信的路由冲突协调,具有较好的网络通信分流控制效果,避免了路由冲突,提高了通信信道传输的吞吐量。

Due to the differences between the users＇ ？ terminal bandwidths, the muhimode optical fiber networkeasily leads to routing conflict. To improve the network connectivity and the equilibrium of communication channel, a routing conflict coordination mechanism of multimode optical fiber communication based on node coverage area adaptive task scheduling and communication channel balanced modulation is proposed. Firstly, building the communication channel model of muhimode optical fiber network, designing the routing detection model through distributed network clustering protocols, computing routing conflict confidence probability of multimode optical fiber network. And then, extracting the energy spectrum feature in node coverage area of multimode optical fiber network communication chan- nel, scheduling adaptive task according to the energy spectrum feature, to achieve routing contention resolution by communication channel equilibrium modulation method. Finally, the networking analysis and experimental results shows that this method has good control effect of networking communication distribution. It avoided routing conflict and improved the throughput of communication channel transmission.
