摘要 随着网络技术的飞速发展,新的多媒体应用,如视频广播、视频点播、会议电话等不断涌现。如果仅仅使用传统单播技术,将会给电信运营商带来巨大的带宽浪费,而组播技术能在一定范围内有效缓解带宽消耗。该文通过深入研究IPTV系统的组播技术,分别从体系结构和协议方面提出基于MPLS网络的差分服务模型、基于QoS参数的PIM-SM模型等策略保证IPTV组播的服务质量。 With the rapid development of network technology,new multimedia applications such as video broadcasting,video on demand,conference phones are emerging.If we only use traditional unicast technology,it will carry a tremendous waste of bandwidth.while multicast can effectively alleviate bandwidth consumption in some digree.Through studying multicast in IPTV systems in-depth,this paper proposed two strategies DiffServ over MPLS model and PIM-SM based on QoS parameters model from architecture and protocol to ensure quality of service multicast in IPTV.
