Connection reservation algorithm in a Web server with service differentiation

Abstract

This paper presents an architecture prototype, named Web Server with Service Differentiation, able to provide QoS to different classes of services. With the implemented prototype, an admission control algorithm, named connection reservation algorithm is proposed and compared to the negotiation algorithm. The results of the performance evaluation have showed both algorithms met proportionally a higher number of high priority class (Class 1) requests in relation to low priority class (Class 2), although the connection reservation algorithm fitted all workload variance better. The connection reservation algorithm can be extended to the Web, where workload dynamic characteristics predominate.
