Go-Back NARQ protocol is also known as Go-back N-automatic repeat request. Error correction in stop and wait ARQ is done by keeping a copy of the sent frame and retransmitting the frame when the time expires.ĭrawback: It is a very inefficient mechanism because at one moment only one frame is transmitted. Lost frames are needed to be resent in this protocol. When the frame arrives at the receiver site, it is checked and if it is corrupted, then discarded. To detect and correct corrupted frames, we need to add redundancy bits to our data frame. ![]() Stop and wait ARQ, adds a simple error control mechanism to the stop and wait protocol. It stands for stop and wait automatic repeat request. The sliding window protocols in computer networks is further divided into three categories as follows: Stop and Wait ARQ Protocol Using these protocols, we can send multiple frames at a time. ![]() At the destination end, the sequence number is used to find the missing frames. ![]() In this mechanism, a frame is sent with a sequence number. Sliding window protocol in computer networks is used for noisy channels. Sliding Window Protocol in Computer Networks
