![]() ![]() ![]() When the timer expires then the receiver sends the cumulative acknowledgement for all the frames that are unacknowledged by the receiver at that moment. This protocol makes the use of cumulative acknowledgements means here the receiver maintains an acknowledgement timer whenever the receiver receives a new frame from the sender then it starts a new acknowledgement timer. In Go-Back-N ARQ, the size of the sender is N and the size of the receiver window is always 1. This protocol is a practical approach to the sliding window. The sender keeps a copy of each frame until the arrival of acknowledgement. Go-Back-N ARQ is mainly a specific instance of Automatic Repeat Request (ARQ) protocol where the sending process continues to send a number of frames as specified by the window size even without receiving an acknowledgement (ACK) packet from the receiver. In this tutorial, we will be covering the Go-Back-N Automatic Repeat Request protocol for Noisey channels in the data link layer.
