| Abstract: | For the database cluster load problem,a dynamic load balancing algorithm is given. Multi-node load balancing measurement and real-time monitoring is designed and implemented,such as CPU utilization,storage capacity,disk response efficiency,network delay,memory utilization and so on. Through load information of the nodes,the algorithm can get load mission groups,and attains load balancing. Performance analysis and simulation results show the algorithm has lower system cost and better load balancing factor. |
