Abstract:

Load balancing is one of the most important technical methods for improving the overall performance of clustered databases. On the basis of comparisons of several present load balancing methods, we present a multi-criteria dynamic load balancing method.The method was designed to collect load state at all the backends of the cluster, make an ordered sequence of the backends using TOPSIS multi-criteria decision method, and send the request to the backend supposed to be the lightest in burden. On the basis of the experimental results we come to the conclusion that the method does improve the performance of the clustered database system compared to traditional load balancing methods.

Key words: clustered database, load balancing, multi-criteria decision, load detect
