CORRECT TEXT
Fill in the blank with the appropriate term.The ______________is a communication protocol that
communicates information between the network routers and the multicast end stations.

Answer: IGMP

Explanation:

The Internet Group Management Protocol (IGMP) is a communication protocol that communicates
information between the network routers and the multicast end stations. It allows the receivers to
request a multicast data stream from a specific group address. However, multicast traffic is sent to
a single MAC address but is processed by multiple hosts.The IGMP allows an end station to
connect to a multicast group and leave it, while being connected to the group address. It can be
effectively used for gaming and showing online videos. Although it does not actually act as a
transport protocol, it operates above the network layer. It is analogous to ICMP for unicast
connections. It is susceptible to some attacks, so firewalls commonly allow the user to disable it if
not needed.
