Implementation of IGMP V3 Protocol
Bai Daming · Journal of Spacecraft TT&C Technology · 2012
Based on study of IGMP(Internet Group Management Protocol) V3 and its previous versions,raw sockets are used to intercept IGMP V3 relationship query packets and IGMP V3 relationship report messages are simulated to spoof switches/routes in order to maintain the membership relationship.This successfully enables support of SSM(Source-Specific Multicast) of terminal equipment running Windows 2000.Simulation test and actual applications show that the method can be used in other operating systems that don't support IGMP V3 protocol.
