METHOD AND SYSTEM FOR SCHEDULED STREAMING OF BEST EFFORT DATA

摘要

A sytem (200) is provided for controlling the transmission of best-effort filed data or programs on channels (202) from one of the controllers (350,360,370) to one or more client nodes (240). Aprogram is a group of with information indicating to a client node (240) how to use the files of the program. A channel (202) is a virtual path. A client node (240) can receive program files from different channels (202) in a separate fashion. Channels (202) have channel information. Client nodes (240) send back positively acknowledge for data received and negative acknowledgments for data not received. The negative acknowledgements can be consolidated to reduce the number of packets. The format of packets carrying program files and acknowledgement/negative acknowledgement messages are specified.
