Switch Management and Operating Concepts

Multicasting

Multicasting is a group of protocols and tools that enable a single source point to send packets to groups of multiple destination points with persistent connections that last for some amount of time. The main advantage of multicasting, when compared to broadcasting, is a decrease in the network load.

•Broadcast packets are sent to all devices on a subnetwork.

•Unicast packets are sent from a single network device to another single network device.

•Multicast packets are sent to a group of network devices.

The following table lists some of the permanently assigned multicast addresses.
