13.1 Overview

This section provides information for Multicast in Monitor.
Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender to 1 recipient)
or Broadcast (1 sender to everybody on the network). Multicast delivers IP packets to just a group
of hosts on the network.
IGMP (Internet Group Management Protocol) is a network-layer protocol used to establish
membership in an IPv4 multicast group - it is not used to carry user data. Refer to RFC 1112, RFC
2236 and RFC 3376 for information on IGMP versions 1, 2 and 3 respectively.
