摘要
随着计算机技术和电力系统应用软件技术的快速发展,电力信息系统服务器的并发访问需求日益强烈。本文提出了一种基于负载权值的均衡算法的解决方案,该方案充分考虑该集群系统的各个节点负载压力状况,收集并反馈给负载均衡器,再基于算法给出各节点上的权值大小,从而有针对性地提高各节点的负载均衡性。最后通过与Connection算法以及模拟退火算法对比实验表明,该方案能够维持各节点上负载均匀,并且提高系统的响应能力、并发能力和稳定性。
With the rapid development of computer technology power system application software technology, concurrent access to servers of power information system requirements increased strongly. This paper proposed a solution based on the balance of the load weight algorithm, this scheme fully considered the various nodes of the cluster system load stress status, collecting and feedback the load balancer, and then based on the algorithm given weights on each node size, to improve the load balance of each nodes. Finally, comparative experiments with Connection algorithm and simulated annealing algorithm showed that the scheme maintained uniform load on each node, and improved responsiveness, concurrent ability and stability of the system.
