  1. The Go Back N protocol is more used because it is less complex to implement in the network. Moreover, it is comparatively less expensive as it requires less storage. If the window size is equal for both Go-Back-N and selective repeat protocol, then the efficiency of both these protocols is almost equal.

  2. Nov 3, 2023 · Advertisements. A Protocol Using Go Back N - Go-Back-N protocol, also called Go-Back-N Automatic Repeat reQuest, is a data link layer protocol that uses a sliding window method for reliable and sequential delivery of data frames. It is a case of sliding window protocol having to send window size of N and receiving window size of 1.Working Prin.

  3. Mar 18, 2024 · In this tutorial, we’ll discuss a protocol used for the reliable delivery of data packets in networks: Selective Repeat Protocol (SRP). Furthermore, we’ll present an example of packet transmission using the SRP. Finally, we’ll highlight some crucial advantages and disadvantages of this protocol. 2. Introduction

  4. Go-Back-N ARQ. Go-Back-N ARQ protocol is also known as Go-Back-N Automatic Repeat Request. It is a data link layer protocol that uses a sliding window method. In this, if any frame is corrupted or lost, all subsequent frames have to be sent again. The size of the sender window is N in this protocol. For example, Go-Back-8, the size of the ...

  5. Aug 25, 2022 · The Receiver window size in the Go-Back-N protocol is 1. The Receiver window size in the Selective Repeat technique is N. Minimum Sequence Number : The minimum sequence number in the Stop and Wait procedure is 2. The Minimum Sequence Number in the Go-Back-N protocol is N+1, where N is the number of packets sent.

  6. Feb 26, 2024 · Go-Back-N ARQ. Go-Back-N ARQ allows sending more than one frame before getting the first frame’s acknowledgment. It is also known as sliding window protocol since it makes use of the sliding window notion. There is a limit to the amount of frames that can be sent, and they are numbered consecutively.

  7. GO-BACK-N ARQ employs the protocol pipelining idea, in which numerous frames can be delivered before getting acknowledgment of the first frame. If we have 5 frames and the window size is 3, then frame 1, frame 2, and frame 3 can be sent before anticipating the acknowledgment of frame 1. The frames in Go-Back-N ARQ are numbered consecutively ...
