Traditional approach on advance reservation considers only a fixed scheduled period. When overtime occurs (often quite approaching the endof the originally scheduled service period) depending on network load and resource usage, the service may easily be disrupted due to insufficient resources available. Examples include the broadcasting of sports events and business videoconference calls. In this paper, we study the problem of admission control andresource management for AR service with uncertain service duration. The objective is to maximize user satisfaction in terms of service continuity andguaran tee of QoS while minimizing reservation cost and call blocking probability of the AR service. An innovative two-leg admission control and bandwidth management scheme is proposed. Service continuity, user utility andreserv ation cost functions are proposedhere to evaluate user’s satisfaction andthe efficiency of resource allocation. Simulation results are presented. © Springer-Verlag Berlin Heidelberg 2002. |
