Abstract	According to the growing of Internet, many websites have used clustering technologies to enlarge their performance. These days, LVS (Linux Virtual Server) software, which is free of charge and has good performance, has commonly been used to construct web server cluster. But when requests are increased, LVS can raise a bottleneck and can make the cluster system unable after all, because it has only single front-end. In this paper, we suggest a new architecture for webserver cluster based on LVS with multiple front-ends which can act as back-ends simultaneously. We also propose a scheduling algorithm to distribute requests equally to servers with considering their load. The proposed system and algorithm remove the bottleneck, and are useful in constructing small and middle-sized websites. In the proposed system, a server can make response directly to clientpsilas request only when its load is not large enough. Otherwise, the server should redirect the request to a selected back-end with the lowest load. We hope that the webserver cluster with multiple front-end will be suitable and efficient for constructing small and middle-sized websites at the point of cost and performance.
