基于10 G EPON的IPTV可控组播的实现方式研究

摘要

10 G EPON被称为下一代PON(NG PON)技术,能更好地满足三网融合条件下IPTV等视频业务的高带宽接入需求.为了在10 G EPON系统上承载IFTTV组播业务,需要引入可控组播技术,对10 G EPON系统的组播方式进行控制.主要研究了10 GEPON系统中IPTV可控组播的实现原理及流程,提出,了基于IGMP控制报文和扩展OAM报文实现IPTV组播业务的控制和管理方法.%10 G EPON is regarded as next generation PON technology, which can meet the broadband access needs of video services such as IPTV in triple play. In order to realize the operation of multicast services in 10 G EPON system, controlled multicast technology is introduced to control the multicast operation in 10 G EPON. The realization principle and procedure of IPTV controlled multieast in 10 G EPONare given, and the controland management methods of IPTV multicast based on IGMP controlled message and extended OAM message are proposed.
