Go-back-N: Note that the formula given in the problem is for T ax =0. Suppose we make this approximation ignoring T ax. We will get a more optimistic result: The sliding window (pipelined) protocols achieve utilization of network bandwidth by not requiring the sender to wait for an acknowledgment before sending another frame. In Go-Back-N, the sender controls the flow of packets, meaning we’ve got a simple and dummy receiver.Therefore, we’ll start by … See more 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 … See more The Go-Back-N protocol adopts the use of cumulative acknowledgments. That is, receiving acknowledgment for frame means the frames , , and so on are acknowledged as well. We denote such acknowledgments as … See more To sum up, the Go-Back-N protocol works for both the sender and the receiver side to ensure reliable data transfer. We also discussed how the … See more As we stated before, pipelined protocols are an improvement over the stop-and-wait protocol. To achieve better network utilization, we have multiple frames “in-flight” between the sender and the receiver at a given time. … See more

Difference between Stop and Wait, GoBackN and Selective Repeat
WebJan 4, 2024 · The three main characteristic features of GBN are: Sender Window Size (WS) It is N itself. If we say the protocol is GB10, then Ws = 10. N should be always greater … WebJul 30, 2024 · Go – Back – N ARQ provides for sending multiple frames before receiving the acknowledgment for the first frame. It uses the concept of sliding window, and so is also called sliding window protocol. The frames are sequentially numbered and a finite number of frames are sent. WebGo back N is an implementation of Sliding Window Protocol. In Go back N Protocol, sender window size = N and receiver window size is always 1. The features of Go back N protocol are mentioned.
