Multicast Networking

Multicast networking is a method for efficiently sending data to multiple specific recipients simultaneously over a network. Instead of sending individual copies of data to each recipient (unicast) or broadcasting to all devices (like a loudspeaker), multicast targets only a selected group that has joined a specific “channel” or group. This conserves bandwidth and resources, making it ideal for streaming live video, online gaming, or real-time data updates. Devices join a multicast group to receive the data, which is managed by network protocols designed to deliver information efficiently to multiple users without unnecessary duplication.
