WebJan 6, 2024 · Selective Repeat Protocol. 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.

WebGo Back N ARQ (Sliding Window) • Stop and Wait is inefficient when propagation delay is larger than the packet transmission time – Can only send one packet per round-trip time • Go Back N allows the transmission of new packets before earlier ones are acknowledged • Go back N uses a window mechanism where the sender can send coachman 560/4Go-Back-N ARQ is a specific instance of the automatic repeat request (ARQ) protocol, in which the sending process continues to send a number of frames specified by a window size even without receiving an acknowledgement (ACK) packet from the receiver.
