WebGo-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. se-uql#toggleEditor'>. Web12 jul. 2024 · Go-Back-N ARQ is a sliding window protocol which is used for flow control purposes. Multiple frames present in a single window are sent together from sender to receiver. Pipelining is allowed in the Go-Back-N ARQ protocol. Pipelining means sending a frame before receiving the acknowledgment for the previously sent frame.
