Multicast
Sending traffic from one source to a single destination is called Unicast traffic. Sending traffic from one source to everyone in the subnet is called a Broadcast traffic.
Sending traffic from one (or multiple) sources to a group of receivers is called multicast.
Multicast on IP networks uses various Layer 2 and Layer 3 features and technologies enable its operation.
