| 摘 要： | 提出一种在EPON系统上实现IPTV组播业务的方案,该方案通过重新定义逻辑链路标识(LLID)作为VLAN的标志,把具有相同节目频道业务的ONU划分到同一个VLAN上,实现组播功能。并在OLT和ONU分别执行因特网组管理协议代理(IGMP Proxy)和监听(IGMP Snooping)机制对组播成员进行管理,大大减少了组播控制报文的开销。最后用现场可编程门阵列(FPGA)设计实现该方案的主要功能模块,通过仿真验证该方案的可行性。

| Abstract: | A scheme loading IPTV multicast service on EPON system is proposed.By redefining LLID as a flag of VLAN,this scheme classes ONU with the same program service into a VLAN to realize multicast function.It also manages the multicast members to significantly reduce overhead of multicast control message by using IGMP Proxy at OLT and IGMP Snooping at ONUs.Simulation results indicates the feasibility of this scheme by using FPGA to design the main function modules. |
