Who knows where you try to send the packets. First lets take the 'server', which calls sendto with clientaddr which you haven't initialized. Sliding Window Protocol Program in Cīelow is the simulation of sliding window protocol in C. The 'client' and 'server' program contains some dubious code. Go back n: Sender transmits all frames present in the window that occurs after the error bit including error bit also. Selective Repeat: Sender transmits only that frame which is erroneous or is lost.Ģ. In sliding window protocol the receiver has to have some memory to compensate any loss in transmission or if the frames are received unordered.ġ. If receiver sends a collective or cumulative acknowledgement to sender then it understands that more than one frames are properly received, for eg:- if ack of frame 3 is received it understands that frame 1 and frame 2 are received properly. If window size=w then after sending w frames sender waits for the acknowledgement (ack) of the first frame.Īs soon as sender receives the acknowledgement of a frame it is replaced by the next frames to be transmitted by the sender. Then, waits for the feedback of the comfy and cute winter outfits define stop and wait protocol mean c-program-to-implement-stop-and-wait-protocol.pdf.
