Abstract
Multicast Call Admission Control (CAC) is the key issue of NGN QoS. Based on the analysis of existing CAC mechanisms, a fuzzy-logic-controlled multicast call admission control mechanism was proposed, termed FMAC. FMAC considered four parameters, including quality of service, network congestion status parameters, available capacity and equivalent bandwidth, as fuzzy input for CAC. with fuzzy inference, the decision of acceptance of new multicast call was obtained. FMAC was proved to be scalable, easy to implement, and suitable for both unicast and multicast. Simulations with multicast services show that, FMAC can reach high network exploitation while statistically meet the needs of users on QoS, and can keep low values of blocking frequency when the network is correctly dimensioned.
