COMMUNICATION DEVICE AND METHOD

摘要

A method for controlling a communication between a sender and a receiver operating in accordance with TCP, where the sender marks segments being sent by including a designated single bit in each sent segment such that an original transmission may be distinguished from a retransmission, and the receiver marks the acknowledgment segment for a received segment by including the single bit contained in said received segment in the acknowledgment segment for said received segment, such that the acknowledgment of an originally sent segment may be distinguished from the acknowledgment of the retransmission of said segment.
