An Extension-Based Dynamic Load Balancing Model of Heterogeneous Server Cluster

Load balancing is a classical problem and a research hotspot of Web intelligence. DNS load balancing is the pioneer load balancing technology. But the existing DNS dynamic load balancing strategies have shortages. This paper puts forward a new load balancing method, which is to connect extension theory with load balancing. Extension engineering method is initially proposed by Prof. Cai Wen. It has been successfully used in various applications. In this paper, we use the operation of matter-element theory, extension set, and dependent function in extension theory as well as the membership degree of fuzzy math to set up an extension-based dynamic load balancing model of heterogeneous server cluster. It is proved by experiment that the load balancing strategy is more effective, dynamic, steady-going and in real time by using this new model.
