Consider transferring an enormous file of L bytes from Host A to Host B. Assume an MSS of 536 bytes. A. What is the maximum value of L such that TCP sequence numbers are not exhausted? Recall that the TCP sequence number field has 4 bytes. B. For the L you obtain in (a), find how long it takes to transmit the file. Assume that a total of 66 bytes of transport, network and data-link header are added to each segment before the resulting packet is sent out over a 155 Mbps link. Ignore flow...
