Design and performance of a QoS mediation platform

Integrated services in the Internet require dynamic and efficient usage of resources. This paper describes a mediation platform architecture developed to control resources and to perform the interface between generic clients and servers in ISPs environments. It offers the QoS required by the client through ABT connections. An experimental platform relying on HTTP transactions is described and performance issues including scalability are discussed. We show the trade off between the relevant parameters and their effect on the overall performance.
