Transparency dynamic feed-back load balancing algorithm based on cluster system

With the broadly adoption of server cluster systems in the enterprise information system,the traditional algorithm of load balancing can not satisfy the requirement of enterprise because of either the expensive hardware cost or the limitation of algorithm itself.A cluster-based transparency dynamic feed-back load balancing algorithm(TDLBA)was presented.To simplify the distribution of the load balancer,increase the throughput rate and decrease the response time of the system,various resources were considered abundantly(such as CPU,memory,I/O and network bandwidth),redundant backup strategy was used,the dynamic feed back algorithm of the server nodes was adopted,and a redundant load node was introduced for the dynamic adjustment of load allocation.The test shows that this algorithm improves the service capability of the system more effectively compared with static allocation algorithm and Pick-KX algorithm.
