Go back n utilization formula
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 WebSliding window protocol is a flow control protocol. It allows the sender to send multiple frames before needing the acknowledgements. Sender slides its window on receiving the acknowledgements for the sent frames. This allows the sender to send more frames. It is called so because it involves sliding of sender’s window.
