Abstract
Abstract A data transmission method quickly and reliably transmits data (e.g., a file) from a source to one or more recipients over a communications link. The method includes transmitting the data, which are in the form of a plurality of frames, from the source over the link to one or more of the recipients until all of the plurality of frames have been transmitted over the link. While the data are being transmitted by the source, acknowledgments from one or more of the recipients are received by the source. The acknowledgments indicate which frames require retransmission. After all of the frames have been transmitted over the link, a retransmission is performed by the source for only those frames which the acknowledgments indicate as requiring retransmission.

Claim 5
Independent Claim
100 words
A method for quickly and reliably transmitting data to at least two recipients over a communications link comprising; (A) transmitting a plurality of frames of data over the link to the recipients until all of the plurality of frames have been transmitted; (B) while performing step (A), receiving acknowledgments from one or more of the recipients, the acknowledgments including indications of frames requiring retransmission; and (C) after all of the plurality of frames have been transmitted, repeating until a predetermined amount of time has passed steps (A), (B), and (C) for only those frames which the acknowledgments indicate require retransmission.
