Abstract
A data transfer system (100) includes a data transmission device (103). The data transmission device can include a data communication circuit (206), a memory (202), and a control circuit (201) operable with the communication circuit and the memory circuit. The control circuit can transfer data (306) to a remote device, establish a sliding window (307) spanning a predetermined amount of data, and store the predetermined amount of data. In response to receiving an error message (311) identifying particular data (312) encountering errors in transfer, the control circuit can retransfer the particular data so long as the particular data is within the sliding window.
Claims20
A method of transferring data, comprising:
- initiating transfer of the data from a data communication circuit;
- establishing, with a control circuit, a sliding window spanning a predetermined subset amount of data;
- buffering data, in a memory circuit, the predetermined subset amount of data;
- deleting, from the memory circuit, data outside the sliding window;
- receiving, with the data communication circuit, at least one error message in response to the initiating, the at least one error message identifying particular data encountering errors in transmission;
- determining, with the control circuit, whether the particular data is within the sliding window;
- and
- where the particular data is within the sliding window, retransmitting, with the data communication circuit, the particular data.
