It is a technique that generally observes the proper flow of data from sender to receiver. It is very essential because it is possible for sender to transmit data or information at very fast rate and hence receiver can receive this information and process it.

This protocol is almost like Go-Back-N ARQ protocol, or we can say that it is a modified form of GBN ARQ, the part where it differs is that here buffers are used and both receiver & sender maintain a window of size. This selective repeat works better at times when the network link is mostly unreliable. creating rdlc report without dataset.xsd

WebUsing the Go-Back-N ARQ protocol leads to the retransmission of the lost frames after the expiry of the timeout timer. The Need of Go-Back-N ARQ This protocol is used to send more than one frame at a time. With the help of Go-Back-N ARQ, there is a reduction in the waiting time of the sender. WebJul 1, 2024 · Go-back-n ARQ protocol is a sliding window protocol that uses the concept of pipelining. In go-back-n, the ‘N” determines the size of the sender window. The value of N defines the number of frames that can be sent while the sender is waiting for the acknowledgement.

Go – Back – N ARQ − Go – Back – N ARQ provides for sending multiple frames before receiving the acknowledgement for the first frame. It uses the concept of sliding window, and so is also called sliding window protocol. WebVariations of ARQ protocols include Stop-and-wait ARQ, Go-Back-N ARQ, and Selective Repeat ARQ. All three protocols usually use some form of sliding window protocol to help the sender determine which (if any) packets need to be retransmitted. These protocols reside in the data link or transport layers (layers 2 and 4) of the OSI model. Examples
