Service Categorization and Admission Control in Enterprise Web Services Using Capacity Distribution Algorithm

Enterprises providing services through Internet must use online services supplied by other enterprises to compose the final services required by their end clients. The paper is aimed at providing services to the organization using service categorization mechanism which ensures stable QOS guarantees. This mechanism considers classes of requests and categories of consumers. It groups the requests carried out by consumers in secure sessions. In order that consumer servers can provide end clients with the appropriate quality of service, they must be guaranteed a determined QoS from the provider server. Under overload, this mechanism favors premium customers over basic customers so that premium customers can be protected, which maximizes the throughput and minimizes the response time. The main objective of this paper is QOS Control mechanism carries out an effective differentiation of the service provided to the consumers. It also focuses the reserving the processing capacity of the cluster for the preferential consumers during the overload periods.
