IGMP
(Internet Group Multicast Protocol) The protocol that governs the management of multicast groups in a TCP/IP network. To sign up for a multicast group, a Host Membership Report is sent by a user's machine to its nearest routers, which forward that data to routers outside the local network. The routers are kept current by polling the users' machines with Host Membership Query messages. See multicast.Copyright © 1981-2019 by The Computer Language Company Inc. All Rights reserved.
