Suppose that we attempt to run the sliding window algorithm with SWS = RWS = 3 and with Max SeqNum = 5. The Nth packet DATA[N] thus actually contains N mod 5 in its sequence number field. Give an example in which the algorithm becomes confused; that is, a scenario in which the receiver expects DATA[5] and accepts DATA[0]-which has the same transmitted sequence number-in its stead. No packets may arrive out of order. Note this implies MaxSeqNum ≥ 6 is necessary as well as sufficient.
