Abstract :
Within the NGN architecture, the resource and admission control functions (RACF) act as the arbitrator between service control functions and transport functions for QoS related transport resource control within access and core networks. The decision is based on transport subscription information, SLAs, network policy rules, service priority and transport resource status and utilization information. This paper provides a mechanism for resource control and functional architecture of overlay multicast for IPTV service in NGN.
