Research On Load Balancing Scheduling Strategy In Server Cluster System Based On C/S Structure

Server cluster plays a more and more important role in the Internet society,load balancing algorithm is server clustering performance and availability of the key factors.In this paper,we analyzed the present situation of the cluster system and the advantages and disadvantages of existing load balancing algorithm,proposed a server cluster system based on C/S architecture of load balancing solutions.The main work includes:(1)In the Linux virtual server(LVS),on the basis of cluster on the LVS existing load balancing algorithm is improved,and a dynamic adaptive load balancing algorithm is proposed.Joined to the CPU,memory,disk IO,calculate the system overhead,such as bandwidth,improve the accuracy of the node server load calculation.(2)A new client scheduling algorithm,at the time of load balance stress or crash,the client automatically open support scheduling function,improve the system reliability and throughput.(3)Through constructing a specific cluster environment,using the pressure measuring tool to conduct stress tests on the system.After the test,the load balancing scheme has achieved good effect.
