System Resource Allocation Algorithm for Multicast Service in NGN

It is necessary to control service requests with definite criteria in order to ensure end-to-end guarantee of quality of service (QoS) in the constraints limited system capacity. For including the aspect of system operation in the performance index, we define a system cost function as 'GAIN' with the terms 'reward' and 'penalty' respectively. Thus we find the allocation set which maximizes the system GAIN and the service guaranteed conditioning. For the performance analysis, we show that the system can be modeled as M/G/m/m with limited capacity, investigate GAIN under various traffic conditions in context of NGN realization.
