基于Kent映射的数字集群动态负载均衡算法研究
Research on Dynamic Load Balancing Algorithm of Digital Trunking Based on Kent Map
摘要
Abstract
Dynamic load balancing is an indispensable link to ensure the normal operation of digital trunking system,but it is easy to be disturbed by communication failures and other problems in the control process.Therefore,a dynamic load balancing algorithm for digital trunking based on Kent mapping is proposed.The virtual machine system based on cloud platform collects data information such as the number of node connections,response time,dynamic load of the digital cluster,and analyzes the load of the digital cluster system.Secondly,a resource utilization model of digital trunking is constructed,and the resource utilization of digital trunking is obtained by solving the model with the Grey Wolf algorithm based on Kent map.Finally,the resource utilization rate is input into the LQR(Linear Quadratic Regulator)control loop,and the dynamic load balancing of the digital cluster is realized by controlling the migration of the server.The experimental results show that the digital trunking processed by the proposed algorithm has short response time,large fitness value,and strong fault tolerance ability.关键词
