摘　　要：数字电视信号对传输质量有着十分严苛的要求,传统网际互连协议(Internet Protocol,IP)网络在提供端到端服务质量(Quality of Service,QoS)保障方面仍面临诸多挑战。对此,分析数字电视信号的业务特点和传输需求,梳理IP网络QoS领域的发展脉络,提出一种端到端QoS保障解决方案的总体架构,从接入网、骨干网、综合管理平台三个层面给出优化措施。Digital television signals have very strict requirements for transmission quality,and traditional Internet Protocol(IP)networks still face many challenges in providing end-to-end Quality of Service(QoS)guarantees.In this regard,this paper analyzes the service characteristics and transmission requirements of digital television signals,combs the development context of IP network QoS field,proposes an overall architecture of end-to-end QoS guarantee solution,and gives optimization measures from the three levels of access network,backbone network and integrated management platform.
