Netgear M4300-48X (XSM4348CS) - Stackable Switches with Full PoE+ Provisioning ユーザーズマニュアル

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.

Multicast is supported on the M4300 series switches only.
