Although these kinds of cluster have more complex struc - ture, they can overcome limitations of traditional cluster and provide resolutions with good quality, large capacity and high perfor - mance compared to LVS. Base on a model of distributed cluster, named CG tree, the author design his algorithms to manipulate CG 技 trees. The scheme can efficiently reduce the cost of intercommunication between different networks, and can automatically adjust tree to ensure high availability when cluster faults occur. The result of simulated experiments indicates that the system has quite good per- 术 formance. Key words: Distributed cluster; CG tree; LVS 创 1 引言 要多次尝试才能知道哪个链接的效果好。 新 随着社会的
