Multicast Overview
Multicast is best suited for video and audio traffic requiring multicast packet control for
optimal operation. Multicast includes support for IGMPv2 and IGMPv3. Communication from
point to multipoint is called multicasting. The source host (point) transmits a message to a
group of zero or more hosts (multipoint) that are identified by a single IP destination address.
Although the task can be accomplished by sending unicast (point-to-point) messages to each
of the destination hosts, multicasting is the more desirable method for this type of
transmission. A multicast message is delivered to all members of its destination host group
with the same best-efforts reliability as regular unicast IP messages. The message is not
guaranteed to arrive intact at all members of the destination group or in the same order
relative to other messages.
