| 摘 要： | 首先讨论了在GPON中实现组播的意义,在对现有的二层组播协议分析与比较的基础上提出采用IGMP SNOOPING协议在GPON上实现组播,并结合GPON自身的特点,提出了一种新的实现方案,描述了OLT和ONU对IP组播业务数据报的处理过程,以及对GPON用户终端设备加入、离开组播组的IGMP协议帧的处理过程.最后详细说明了基于IPTV业务的组播技术在GPON中的应用以及组播技术在GPON中应用的优势.

| Abstract: | at first,the meaning of implementing multicast in GPON is discussed,and on the basics of analyzing and comparing of the present second layer multicast protocol,it is proposed to implement multicast in GPON using IGMP SNOOPING protocol. At the same time,a novel implementation scheme is proposed in conjunction with the characteristic of the GPON. The new scheme describes the processing to IP multicast service data by OLT and ONU,and the processing of the IGMP frame of the users' terminal devices entering or leaving the multicast group. At last,the application of the multicast technology based on IPTV service in GPON and the advantages of such application are described in detail. |
