移动网络数据传输路径负载均衡性配置仿真

摘要

对移动网络数据传输路径负载的均衡性配置,能够有效改善网络大量数据传输引起的链路拥塞现象.对数据路径负载的均衡性配置,需要通过链路评估算法考虑通信链路关键度,选择最佳转发链路,完成负载均衡性配置.传统方法结合最小权值方法,对转发节点进行广泛选取,到忽略了对最佳转发链路的获取,导致负载配置精度偏低.提出基于移动网络节点和链路评估的负载均衡性配置方法,根据节点带宽利用率,去除节点负载最接近设置的节点转发阈值上限的节点,计算各个节点的可调用带宽,选择出最佳的转发节点;采用链路评估算法综合考虑通信链路关键度,根据通信链路剩余带宽选择最佳转发链路;通过调整动态负载均衡性配置阈值对传输的数据进行的调度,实现数据传输路径负载均衡性配置.实验证明,所提方法在数据传输成功率、吞吐率、网络资源利用率方面均有所改善.%This paper proposes a collocation method for load balance based on evaluation of node and link of mobile network.We eliminate node whose load is the nearest to the set upper forwarding threshold and calculate callable bandwidth of each node,then select the optimum forwarding node.The link evaluation algorithm is used to consider criticality of communication link and selected optimum forwarding link according to remaining bandwidth of the communication link.The transmission data are dispatched via adjusting collocation threshold of dynamic load balance.Thus,the collocation of the load balance is achieved.Simulation proves that the method improves transmission rate of data,throughput rate and network resource utilization.
