The destination terminal returns an acknowledgment packet in response to each data packet being withdrawn from the receive buffer. The acknowledging packet includes a flow control variable which is incremented by a unit value in response to the data packet being withdrawn from the receive buffer. The source terminal transmits one or more data packets having sequence numbers the largest of which is determined by a maximum number of outstanding data packets awaiting receipt of the acknowledging packet by the source data terminal and the flow control variable contained in the acknowledging packet. | |
