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.
在NGN架构中，RACF (resource and admission control function)作为业务控制功能和传输功能之间的仲裁器，在接入网和核心网中实现与QoS相关的传输资源控制。决策基于传输订阅信息、sla、网络策略规则、服务优先级以及传输资源状态和利用信息。提出了NGN下IPTV覆盖组播业务的资源控制机制和功能体系结构。
