摘　　要：支撑有线电视网络向多业务发展的下一代广播网(NGB)是目前研究的重点,其中承载网络IP化、综合业务平台、端到端网络构架以及综合运营支撑系统等是目前研究的重点课题。从信息通信网络解聚融合的发展历程分析入手,给出了一种有线NGB体系参考模型,该模型通过去耦合组成多业务系统的各种网络资源和IT资源,实现资源重用和系统的可扩展性,除了网络功能组件以外,该模型同样适用于基于地面广播和卫星的NGB系统。Cable network operators are evolving into multi-services players, which is the key requirement of the Next Generation Broadcasting system （NGB）. IP-based network convergence, service delivery platform, endto-end networking and Business/Operation support system （BOSS） are the most important topics related to NGB. In this paper, the decoupling and convergence technologies of telecommunication network were analyzed, and a reference model of NGB high level architecture was proposed. The given architecture can guarantee the scalability of NGB by decoupling and reusing both network and IT resources.
