ABSTRACT:
Transferring data (such as files) on an end-to-end, high-speed packet-switched network connection (a “virtual circuit”) or on a circuit. An out-of-band path is used for signaling and status messages (control). The same, or a separate, out-of-band path may be used to retransmit chunks of data that were received with errors or that were not received at all. By simplifying the data being sent over the high-speed (virtual) circuit, the resources of the (virtual) circuit are used efficiently since less overhead is required. Further, since the size of the file to be transferred can be predetermined, and since any retransmissions can be made over a path other than the (virtual) circuit, the (virtual) circuit that best meets the needs of the data transfer can be selected, thereby further increasing the efficiency with which the (virtual) circuit is used.
