摘要：To reduce the system bottle and improve the response speed of load banlancer, the factors influencing the load balancing are analyzed. Through the research on key technologies of current strategies and scheduling algorithms, a scheme for database deployment based on RAID technology is proposed. On the basis of our research, an extensible and centralized object-oriented load balancer is also put forward using the middlewares. This load balancer makes load collection, load decision and components placement at master nodes. It adopts the object-oriented technology to objectify each component. The proxy object is applied to complete database operation. It can feedback database information in time to make decision. So this object has the function to select algorithm modules dynamicly, according to actual situation and the difference of data deployment. Its dynamic algorithm can master the load situation of each node well to reach load balancing. Finally, by simulation and experiments, the load balancing algorithm is proved that it can reduce the response time and improve the throughput of system, compared to common load balancing algorithms.
