Consider transferring an enormous file of L bytes from host A to host B. Assume an MSS (Maximum Segment Size) of 1460 bytes.
a) What is the maximum value of L such that TCP sequence numbers are not exhausted? Recall that the TCP sequence number filed has four 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 10 Mbps link. Ignore flow control and congestion control so A can pump out the segments back to back and continuously.
Determine an Internet address for this domain name. Under what situations is each of the following statements true of the name resolution process?
Determine successive values of congestion window in bytes?
Create a state transition diagram that describes typical patient states and how they change based on specific actions and events.
Assume the file is sent continuously as one big message. How long does it take to send file assuming it is sent continuously.
Is there any protocol which you and Luke can use to avoid defeat? If not, describe why not. If there is protocol that would work, describe it.
Assume nodes A and Bare on the same 10 Mbps Ethernet bus, and the propagation delay between the two nodes is 325 bit times. The answer is no, if B 's signal reaches A before bit time t = 512 + 64 bits. In the worst case, when does B's signal reach A?
