摘要
针对当前光纤延迟网络节点分布式选择存在非最优的问题,提出一种基于正交频分复用的光纤延迟网络光组播分组交换最优分布式节点选择方法。首先构建光纤延迟网络的路由分簇模型,计算节点分组交换的阀值控制因子。采用信任策略构建节点分布式选择的信任博弈模型,采用正交频分复用方法进行光纤延迟网络光组播分组交换的节点选择优化设计。试验结果表明,采用该方法进行光组播分组交换分布式节点选择,能提高节点的自适应组网调节能力,数据包分组交换的传输成功率得到提高。
In order to optimize the current fiber delay network node distribution selection,this paper put forward a method based on orthogonal frequency division multiplexing. First,construct the routing clustering model of fiber delay network to calculate the threshold control factors of nodes packets. Then build the distributed chosen nodes by trust strategy. Finally design the optimal nodes selection of fiber delay network optical multicast packet switching based on orthogonal frequency division multiplexing. Experimental results show that this method can improve the nodes adaptive network adjustment ability and the transmission rate of data packet switching.
