Abstract
Methods and systems for controlling data transfer operations during a communication session between a transmitter and at least one receiver provide that data packets which have been stored at the receiver memory before a disconnect occurred remain stored in therein in the presence of the disconnect to avoid the need for retransmitting data packets upon re-establishment of a communication link. Data representative of those data packets already stored at the receiver memory is maintained for purposes of synchronizing data packet transmission from the transmitter for completing data file transfer. Data control instructions for implementing storage of data packets and tracking the progression of data packet transmissions when a disconnect occurs may suitably included in an existing protocol layer of a communication system or as an additional protocol layer added to the operating system of the communication system.
