Hierarchical cluster for scalable web servers
Jonghyuck Hong, Dongseung Kim · 2001
Cluster architecture is widely used for the avail- ability and scalability of web servers in these days. To increase the performance we have developed a hierarchical architecture for web servers that can accommodate wide range of connection requests by gradually expanding the nodes in proper levels in the hierarchy. Especially, multiple dispatchers can distribute the incoming client requests to various backend servers in the cluster. Experimen- tal results with two-level cluster with dynamic load balancing are included to verify the idea.
