Abstract: Embodiments of the present invention disclose a method, an apparatus and a system for playing a targeted advertisement. An access switch receives an IGMP join packet sent by a user end, snoops the IGMP join packet, and obtains a first mapping relationship; establishes a first multicast forwarding entry according to the first mapping relationship and a pre-saved second mapping relationship between the access port and a virtual local area network of a targeted advertisement user group; and receives an advertisement media stream sent by an access router, and forwards the advertisement media stream to the targeted advertisement user group by using the access port corresponding to the virtual local area network of the targeted advertisement user group according to the first multicast forwarding entry. In this way, the problems that placing precision of a region-targeted advertisement is low and audience rating is poor in the prior art is solved.

Abstract translation: 本发明的实施例公开了用于播放目标广告的方法，装置和系统。 接入交换机收到用户端发送的IGMP加入报文，窥探IGMP加入报文，获取第一个映射关系; 根据第一映射关系和目标广告用户组的接入端口和虚拟局域网之间预先保存的第二映射关系建立第一组播转发表项; 并接收由接入路由器发送的广告媒体流，并且根据第一组播转发表项，使用与目标广告用户组的虚拟局域网对应的接入端口，将广告媒体流转发给目标广告用户组。 这样就解决了现有技术中针对区域定向广告的精度偏低，受众评价差的问题。
