What is Go-Back-N ARQ? In Go-Back-N ARQ, N is the sender's window size. Suppose we say that Go-Back-3, which means that the three frames can be sent at a time before expecting the acknowledgment from the receiver.
Sep 2, 2024 · The Go-Back-N (GBN) protocol is a sliding window protocol used in networking for reliable data transmission. It is part of the Automatic Repeat reQuest (ARQ) protocols, which ensure that data is correctly received and that any lost or corrupted packets are retransmitted. The three main characteristic features of GBN are: 1. Sender Window Size (WR)

Mar 18, 2024 · Go-Back-N and Selective Repeat protocols are fundamental sliding window protocols that help us better understand the key idea behind reliable data transfer in the transport layer of computer networks. In this tutorial, we’ll describe how the Go-Back-N protocol works.
Apr 30, 2021 · 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.
Definition. Go-Back-N is a sliding window protocol used in reliable data transfer systems where the sender can send several frames before needing an acknowledgment for the first one. If an error occurs in transmission, the sender must go back and retransmit all frames starting from the erroneous one, ensuring data integrity and ordered delivery.
