Assume that one frame takes 0.300 msec to be placed on the network communication wire from its source, and it takes 18 msec to propagate to its destination. The acknowledgement will take 18 msec to propagate back, plus a negligible amount of time in getting on and off the wire (negligible can be assume to be 0). To operate efficiently, a sliding window protocol must have sending window size large enough to allow the transmitter to keep transmitting until the first acknowledgement has been received. What should be the minimum number of bits in a sequence number? (Hint: How many frames fill up the communication link?) Show all working and reasoning.
I can find the answer for above problem. I need urgently for answer!
