Internet Group Management Protocol (IGMP)
Internet Group Management Protocol (IGMP) provides a way for an Internet computer

Multicasting can be used for such applications as updating the address books of mobile

"broadcasting" high-bandwidth programs of streaming media to an audience that has
"tuned in" by setting up a multicast group membership.
