Abstract: This paper expatiates an Internet Group Management Protocol(IGMP) Snooping implementation thought based on dividing multicast area by VLAN and maintaining VLAN table by snooping the IGMP massage. The paper subsequently brings forward and compares six implementation methods based on tow type thoughts which are on MAC layer and RS layer of Ethernet Passive Optical Network(EPON). The protocol robust problem in current research is brought forward and some modification proposals in data storage and running process aspect are given, and the most superior one is got.
