An efficient and stable cluster system based on improved load balancing algorithm

An efficient and stable cluster system would be proposed in this paper for the load balancing of servers. It bases on the improved load balancing algorithm. The cluster system uses load parameter information including CPU utilization, memory utilization, I/O utilization and network traffic to decide the load of each child node. And it adds a redundant node to collect the load balancing parameters of every child node. The central node can obtain the child node load by exchanging the load balancing information with the redundant node, and then decide which node would respond to a new user request. The improved load balancing algorithm can satisfactorily improve the stability and efficiency of the cluster system.
