The variations of sliding window protocol are Go-Back-N ARQ and Selective Repeat ARQ. Let's understand 'what is Go-Back-N ARQ'. 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.
Mar 18, 2023 · The main difference between these two protocols is that after finding the suspect or damage in sent frames go-back-n protocol re-transmits all the frames whereas selective repeat protocol re-transmits only that frame which is damaged.
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.
Aug 16, 2023 · The go-back-n protocol works well if errors are less, but if the line is poor it wastes a lot of bandwidth on retransmitted frames. An alternative strategy, the selective repeat protocol, is to allow the receiver to accept and buffer t
Jul 12, 2022 · Go Back N ARQ which stands for Go Back N Automatic Repeat Request (ARQ) is a data link layer protocol that is used for data flow control purposes. It is a sliding window protocol in which multiple frames are sent from sender to receiver at once.
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.
choosing a new protocol restarts the simulation. window size. sets the window size for the windows. end to end delay. time a packet takes from one station to the other. timeout. scroll mode. change the style the window scrolls.
