Broadcast traffic is reduced and VXLAN tunnel endpoints (VTEPs) reply to the caller directly. VXLAN can handle BUM in two ways: Multicast and Head End Replication . Multicast is the most common approach, and each VXLAN network identifier (VNI) is mapped to a single multicast group, while each multicast group may map to one or more VNIs.
In this case, data is broadcast to all receivers but only addressed to a specific group. The concept of interactive multicast, for example using IP multicast, may be used over TV broadcast networks to improve efficiency, offer more TV programs, or reduce the required spectrum. Interactive multicast implies that TV programs are sent only over ...
Community television stations in Melbourne and Adelaide also broadcast digital signals, however they typically only broadcast a single SD subchannel which simulcasts that station's primary channel. There have been a number of issues surrounding the introduction of digital subchannels in Australia.
In practice, broadcast packets are not forwarded everywhere on a network, but only to devices within a broadcast domain, making broadcast a relative term. Less common than broadcasting, but perhaps of greater utility and theoretical significance, is multicasting , where a packet is selectively duplicated and copies delivered to each of a set of ...
A digital multicast television network, also known as a diginet or multichannel, is a type of national television service designed to be broadcast terrestrially as a supplementary service to other stations on their digital subchannels. Made possible by the conversion from analog to digital television broadcasting, which left room for additional ...
Broadcast and Multicast Service (BCMCS) is an interface for providing broadcast and multicast services in 3GPP2 CDMA2000 mobile networks. BCMCS can be used to transfer light video and audio clips or other data to a large group of mobile subscribers in an efficient manner. To do so, BCMCS is a so-called point-to-multipoint service.
Commercial broadcasting: for-profit, usually privately owned stations, channels, networks, or services providing programming to the public, supported by the sale of air time to advertisers for radio or television advertisements during or in breaks between programs, often in combination with cable or pay cable subscription fees.
MBMS Operation On-Demand (MOOD) allows dynamic switching between Unicast and Broadcast over LTE, based on configured triggers. The MBMS Bearer Service uses IP multicast addresses for the IP flows. The advantage of the MBMS Bearer Service compared to unicast bearer services (interactive, streaming, etc.) is that the transmission resources in the ...
