摘　　要：通过分析IPTV业务的承载需求,指出通信运营商现有的IP城域网不能满足日益增长的IPTV业务需求,IP城域网需要升级改造。分别从IPTV系统架构、业务接入设计、组播部署、IPoE部署、业务隔离、QoS部署等方面对IP城域网的接入和承载能力进行优化和改造。改造后的应用实践表明:运营商可在现有网络中有效地开展IPTV业务,并保障业务有良好的承载效果。By analyzing the carrTying demands of IPTV business, the author points out that the existing IP network cannot meet the increasing requirements of the IPTV service, so IP metropolitan area network need be upgraded. This paper opti- mizes and transforms IP metropolitan area network about access and load capacity from the IPTV system architecture design, service aecess, multicast deployment, IPoE deployment, service isolation, QoS deploymen and so on. The application of practice after the transformation shows that the operators can effectively carry out the IPTV service in the existing network and ensure good effect.
