| 摘 要： | 分析了当前机群环境下的负载平衡系统主结点选择机制的弊端，提出了将负载方面的知识引入主结点选择的思想．通过提前估算各结点的负载和使用适当的通信机制，便可以科学地选出负载轻、性能好的结点作为主结点故障后的下一个主结点．该机制可以在不降低机群可用性的基础上更好地平衡系统负载．

| Abstract: | This paper analyzed the shortcoming of the mechanisms for Selecting Master applied to loading balance systems, an idea about the introduction of load information to the mechanisms for Selecting Master was proposed. By evaluating the load of nodes and using the proper communicating mechanism, a node with less load and high performance was chosen to act as the new master when the master cannot work. The mechanism can balance the system load well without lowering the availability of cluster. |
