A Method for Load Distribution Used in Multi-Server Environments

A novel scheme is proposed to provide power-saving and prevent server overload in multi-server network environments. It is achieved by partitioning the service capacity of each load server into a sum of its ratio and combining with a switching strategy among servers. Conditions for the choice of the ratio are obtained to guarantee the avoidance of server overload. Two switching strategies among multiple servers are also proposed for even distribution and energy saving in different applications. Simulation results are presented to demonstrate the success of the proposed design.
