Abstract
A system is provided for the controlling the transmission of best-effort filed data or programs on channels from one of plural controllers to one or more client nodes. A program is a group of files and has program information indicating to a client node how to use the files of the program. A channel is a virtual path, wherein a client node can receive program files from different channels in a separate fashion. Channels also have channel information. Multiple controllers are provided which self configure in rank order to control the schedule transmission of programs files on channels. Client nodes receive announcements of programs and channels from the controllers and selectively subscribe to the channels and programs. Client nodes can be instructed to positively acknowledge receipt of programs and also send back negative acknowledgements for ranges of data words in a program files not received. The negative acknowledgements can be consolidated to reduce the number of packets on the network. The format of packets carrying program files and acknowledgement/negative acknowledgement messages are specified.
