摘　　要：本文介绍了MPLS L3VPN组播技术,基于该技术实现了广电城域网内通过三层VPN技术传输组播,可开展IPTV组播业务。组播技术是一种适应一对多模型来缓解带宽压力的技术,使用组播VPN技术既可实现IPTV组播业务,又不需要采购新设备重新组网或者扩大带宽,可节约大量成本。This paper introduces MPLS L3VPN multicast technology,which enables the transmission of multicast within the radio and television metropolitan area network through three-layer VPN technology and enables the development of IPTV multicast services.Multicast technology is a technology that adapts to the one-to-many models to alleviate the pressure on bandwidth.Using the multicast VPN technology not only implements IPTV multicast services,but also saves a lot of costs without purchasing new devices to re-network or expand bandwidth.
