摘要
IPTV通常采用PIM-SM协议实现组播数据的传输,而该协议缺乏对组播源的控制,导致IPTV业务无法正常进行,针对以上问题,提出一种在边缘路由器上的IPTV组播源控制机制,并通过仿真实验验证其对IPTV组播源的控制功能。
PIM-SM protocol is usually used to implement the data transmission of IPTV multicast, but this protocol can not control the multicast source, which makes IPTV service not process in gear. To solute this problem, this paper presents a scheme of IPTV multicast source control on edge router. Simulation results indicate this scheme can fulfill the function of IPTV multicast source control.
