Abstract

This article proposes “Distributed Load Balancing in Web Clustering System via Virtual Token Technique”. The system uses Grouping Protocol as to add or delete web cluster’s members and to make a virtual schedule for them. Load balancing could be done in round-robin fashion, the current head server of the web cluster will be rescheduled as the last server either after its servicing or its service denying caused by its resources insufficiency (memory, CPU usage). The virtual token technique could be implemented by using Group Protocol and monitoring of TCP call request segments and call accept segments. The technique could reduce the need of centralized load balancing server and may avoid of bottleneck of the centralize control point at the high request situation.
