One of the three functions of a sliding window scheme is the orderly delivery of packets which arrive out of sequence. In Go-back-N, the receiver drops packets which arrives out of order. Assume the receiver sends an ACK for every packet it receives. (a) In Go-back-N, what is the required buffer size (receiver’s window size, RWS) at the receiver if sender’s window size (SWS) = 23? What the answer will be in Selective Repeat? (b) In sliding window with SWS = RWS = 5, the minimum required SeqNumSize (the number of available sequence numbers) is 10. Calculate the minimum required SeqNumSize for (i) a sliding window scheme with SWS = 6 and RWS = 3 (ii) a Go-back-N scheme with SWS = 6
