Admission control of multimedia sessions to a set of multimedia servers connected by an enterprise network

The satisfactory electronic delivery of multimedia material not only requires a particular quality of service (QoS) level to be maintained to fulfil users' expectations; there is in addition another goal: maximizing the revenue earned for the network owner. In this paper, we designed an admission controller (AC) along with the necessary algorithms to allow an enterprise network (EN) to satisfy both of these goals. We consider the selection of both a server from several alternatives, and the selection of a delivery route, plus the reservation of resources both in the selected server and on the delivery route to achieve the two goals of guaranteed absolute QoS and revenue optimization. We simulated the AC; simulation results are provided together with explanations.
