Abstract:

In view of the accuracy of the service node weight in weighted least connection algorithm directly affects the load balancing efficiency and the integer cluster system performance. We proposed a new improved algorithm: priority processing capacity weights distribution scheduling algorithm, described the work process and algorithm thought in the improved algorithm, analysed and designed the improved algorithm’s main technology, main module and principle. The improved algorithm solves the LVS load imbalance problem; the LVS performance and stability are improved to some extent. The experiment comparative analysis shows the improved algorithm is more optimal than weighted least connections algorithm in dynamic balance.
