Broadcast FTP Protocol (BFTP)

A one-way IP multicast based resource transfer
protocol, the unidirectional Broadcast File Transfer Protocol (BFTP) is a simple, robust,
one-way resource transfer protocol that is designed to efficiently deliver data in a
one-way broadcast-only environment. This transfer protocol is appropriate for IP
multicast over television vertical blanking interval (IPVBI), in IP multicast carried in
MPEG-2, like with the DVB multiprotocol encapsulation, or in other unidirectional
transport systems. It delivers constant bitrate (CBR) services or opportunistic services,
depending on the characteristics and features of the transport stream multiplexor or VBI
insertion device.
