Negotiation mechanisms on application level: a new approach to improve quality of service in Web servers

This paper describes a negotiation mechanism inserted in a Web server model with differentiated services. All the results of this article have been obtained by means of simulation using for this a queueing network model representing a Web server with QoS. The results also confirm that this new approach enhances the quality of service provided to clients, mainly in overload situations, being an aid in the process of request admission and dropping
