'''Go-Back-N ARQ''' is a specific instance of the [[automatic repeat request]] (ARQ) protocol, in which the sending process continues to send a number of [[Data frame|frames]] specified by a ''window size'' even without receiving an [[acknowledgement (data networks)|acknowledgement]] (ACK) packet from the receiver. It is a special case of the general [[sliding window protocol]] with the transmit window size of N and receive window size of 1.
It can transmit N frames to the peer before requiring an ACK.

The receiver process keeps track of the sequence number of the next frame it expects to receive, and sends that number with every ACK it sends. The receiver will discard any frame that does not have the exact sequence number it expects (either a duplicate frame it already acknowledged, or an out-of-order frame it expects to receive later) and will resend an ACK for the last correct in-order frame.
