摘要
为了提高工业光纤通信网络的路径优化效果和负载均衡能力,提出5G和数字孪生下的工业光纤通信网络路由优化方法,首先结合5G技术和数字孪生技术对工业光纤通信网络展开建模分析,获得网络状态数据;其次,将最小化最大链路利用率和路径时延作为目标,建立工业光纤通信网络路由优化目标函数;最后采用改进的麻雀算法对目标函数求解,实现工业光纤通信网络路由的优化.实验结果表明,所提方法的最大链路利用率在20％以内、路径时延最大值为0.27 s、死亡节点数量为全部节点的1/8,验证了所提方法具有良好的路径优化效果和负载均衡能力.
Abstract
In order to improve the path optimization effect and load balancing ability of industrial fiber optic com-munication network,the routing optimization method of industrial fiber optic communication network under 5G and dig-ital twin is proposed,firstly,the industrial fiber optic communication network is modeled and analyzed with the combi-nation of 5G technology and digital twin technology,and the network state data is obtained;secondly,the minimization of the maximum link utilization rate and the path latency is taken as the objective,and the routing optimization objec-tive function of the industrial fiber optic communication network is established.Finally,the improved sparrow algo-rithm is used to solve the objective function to realize the optimization of industrial fiber optic communication network routing.The experimental results show that the maximum link utilization of the proposed method is within 20％,the maximum path delay is 0.27 s,and the number of dead nodes is 1/8 of all nodes,which verifies that the proposed method has a good path optimization effect and load balancing capability.
