WebThe variations of sliding window protocol are Go-Back-N ARQ and Selective Repeat ARQ. Let's understand 'what is Go-Back-N ARQ'. What is Go-Back-N ARQ? In Go-Back-N ARQ, N is the sender's window size. Suppose we say that Go-Back-3, which means that the three frames can be sent at a time before expecting the acknowledgment from the receiver. Web3) Sliding Window Suppose that we run the sliding window algorithm with SWS(Sender Window Size) = 6 and RWS(Receiver Window Size) = 4, and no out-of-order arrivals. a) Find the smallest value for the “maximum sequence number”(N) to be used for successful transmission via Sliding Window algorithm. N = SWS + RWS – 1 = 6+4-1 = 9
