1. Consider a path from host A to host B through a router X as follows: A- -X-B The capacity of the link AX is denoted Ra, while the capacity of the link XB is denoted Rb in units of [bits/s]. Assume that Ra Ri. Is it possible that the second packet queues at input queue of the second link? Explain. Now suppose that host A sends the second packet T seconds after sending the first packet. How large must T be to ensure no queueing before the second link? Explain.
Host A and B are directly connected with a 100 Mbps link. There is one TCP connection between the two hosts, and Host A is sending to Host B an enormous file over this connection. Host A can send its application data into its TCP socket at a rate as high as 120 Mbps but Host B can read out of its TCP receive buffer at a maximum rate of 50 Mbps. Describe the effect of TCP flow control.
TCP is a connection-oriented protocol. This means that... O a. both of the endpoints communicating over TCP keep information about the state of the connection. O b. a TCP sender can start sending data to the receiver before the three-way handshake takes place. O c. there is a direct physical connection between the two endpoints of a TCP session. O d. both endpoints of a TCP session have to connect to a third party before data can be sent or received.
Suppose A is connected to B via an intermediate router R, as in the previous problem. The A-R link is instantaneous, but the R–B link transmits only one packet each second, one at a time (so two packets take 2 seconds). Assume A sends to B using the sliding window protocol with SWS = 4. For Time = 0, 1, 2, 3, 4, state what packets arrive at and are sent from A and B. How large does the queue at R grow?

2. Now suppose there are two links between source and destination, with one router connecting the two links. Each link is 5,000 km long. Again suppose the MP3 file is sent as one packet. Suppose there is no congestion, so that the packet is transmitted onto the second link as soon as the router receives the entire packet. What is the end-to-end delay?
22. A datagram subnet allows routers to drop packets whenever they need to. The probability of a router discarding a packet is p. Consider the case of a source host connected to the source router, which is connected to the destination router, and then to the destination host. If either of the routers discards a packet, the source host eventually times out and tries again. If both host-router and router-router lines are counted as hops, what is the mean number of a. (a) hops a packet makes per transmission? b. (b) transmissions a packet makes? (c) hops required per received packet?
Suppose Host A sends two consecutive TCP segments to Host B over a TCP connection. The sequence number of the first segment is 748, and the sequence number of the second one is 995. Determine the size of the payload carried by the first segment. Suppose that the first segment is lost but the second segment arrives at host B. What will be the acknowledgment number of the acknowledgment segment that Host B sends to Host A?
