Communication with a single other client is called a unicast. Broadcast is a packet that's sent to all devices on specific network. The operator will actually connect to a multicast IP address of the video stream which is shared amongst all users. 1 Overview In a point-to-multipoint network, packets can be sent in three ways: unicast, broadcast and multicast. There are a range of multicast addresses. IP multicast protocols like IGMP riding atop UDP allow single sent packets to be efficiently replicated reaching multiple destination hosts. However, broadcast traffic will always consume bandwidth for every device in a Vlan Multicast traffic can be pruned inside a single switched ethernet Vlan / broadcast domain, broadcasts by-definition can't be pruned within a broadcast domain. "Multicast" is sending the same information to multiple listening clients in a single operation. So any device that wishes to receive the stream can connect to the relevant port and start receiving.

Host bits set to all 1’s. The transmission technologies broadcast and multicast are different from each other in a context that in the broadcast, the packet is forwarded to all the hosts connected to the network whereas, in multicast, the packet is forwarded only to intended recipients. All multicast traffic is UDP/IP, and various manufacturers and organizations have standardized a wide variety of multicast protocols. Multicast uses UDP (User Datagram Protocol) for “broadcasting” a stream over a closed IP network such as a LAN (Local Area Network) or an IP Service provider’s own network.

The VPN pictured is more like multicast. Multicast protocols are usually UDP protocols, since by definition no connection-state can be maintained. For multicast, the message is only sent to a multicast address, and the network knowledge distributes the data to the host that represents the data sent to the multicast address. UDP broadcast: Most WLAN routers will blindly use group addressed (with visible packet loss) and will use the 1MB/s fallback data rate as the lowest common denominator. UDP multicast functions within an IP range from 224. For UDP broadcast, it engulfs all the UDP 224. In the multicast delivery scenario, each individual stream is sent on a pair of different UDP ports — one for data and the second for the related RTP Control Protocol (RTCP).
