摘要
在负载均衡服务器集群中,负载均衡算法是一个关键部分。针对目前服务器集群使用的负载均衡算法所存在的缺陷:服务器可能出现较大倾斜,本文提出了一种基于粗糙集理论的动静结合的负载均衡算法。该算法避免了服务器间负载的不均衡,能有效地防止服务器倾斜的发生,提高了集群系统的整体性能。
In a load balancing cluster, the core of task distribution is the load balancing algorithm. Considering the defficiency in the load balancing algorithms adopted at present by the cluster servers,we know the servers may be skew. A new load balancing algorithm, which is based on the rough set theory and integrates the strong points of static and dynamic load balancing algorithms, is proposed in this paper. It avoids load imhalancing among servers, prevents the servers to be skew, and improves the performance of the server clustering system.
