In this figure, capital letters specify the physical addresses of the devices and numbers specify the logical addresses of the devices. For example, the device marked as sender has a physical address A and logical address 5. Sender В 20 C/35 D/40 A/5 E/50 Receiver F/60 J/95 I/90 H/82 G/70 Figure 1: Network topology Similarly, the router connected to the sender has physical address B and logical address 20 for the interface that is connected to the sender. Now, consider that process Pi of the sending computer wants to send some data to process P2 of the receiving computer. Port addresses of process Pi and P2 are Px and Py, respectively. Show the contents of the segments, packets and frames for transport, network, and data link layers at the sender side of three hops with appropriate figures.

Consider the figure below. The IP and MAC addresses are shown for nodes A, B, C and D, as well as for the router's interfaces. Consider an IP datagram being sent from node D to node A. Give the source and destination Ethernet addresses, as well as the source and destination addresses of the IP datagram encapsulated within the Ethernet frame at points (5), (4), (2), and (1) in the figure above.
6. Consider a network with some hosts. The traffic from one host to the other is provided. The question is to find the total bytes that are moving in the network from one host to the other and also for all the routes. The total bytes that are transferred for the day is as below. peter ann 1250 peter mary 910 mark mary, 1250 peter mary 450 peter andy 2924 paul peter 1218 paul helen 199 The first name is the source host, the second is the destination host and the number is the bytes that are transferred.
TCP congestion control example. Consider the figure below, where a TCP sender sends 8 TCP segments at t = 1, 2, 3, 4, 5, 6, 7, 8. Suppose the initial value of the sequence number is 0 and every segment sent to the receiver each contains 100 bytes. The delay between the sender and receiver is 5 time units, and so the first segment arrives at the receiver at t = 6. The ACKs sent by the receiver at t = 6, 7, 8, 10, 11, 12 are shown. The TCP segments (if any) sent by the sender at t = 11, 13, 15, 16, 17, 18 are not shown. The segment sent at t=4 is lost, as is the ACK segment sent at t=7.

Host A and B are communicating over a TCP connection, and Host B has already received from A all bytes up through byte 126. Suppose Host A then sends two segments to Host B back-to-back. The first and second segments contain 80 and 40 bytes of data, respectively. In the first segment, the sequence number is 127, the source port number is 302, and the destination port number is 80. Host B sends an acknowledgment whenever it receives a segment from Host A. Suppose the two segments sent by A arrive in order at B. The first acknowledgment is lost and the second acknowledgment arrives after the first timeout interval. Draw a timing diagram, showing these segments and all other segments and acknowledgments sent. (Assume there is no additional packet loss.) For each segment in your figure, provide the sequence number and the number of bytes of data; for each acknowledgment that you add, provide the acknowledgment number.

An IP address can be written as a 32-bit number. For a class B network, the two most significant bits are set to 10. The 16 most signi cant bits are used as a network ID, and the 16 least signi cant bits are used as a host ID. However, the host ID cannot be all 0's or all 1's. How many hosts (i.e., host IDs) can there be on a class B network?

Assume a small communication network, consisting of two user stations and a base station (BS). The users are recording and transmitting data collected by sensors and are transmitting the data frames using frequency band BW, (uplink). BS only collects data and acknowledges them. It uses a different band BWBs (downlink) for transmissions. The uplink and downlink channels are assumed perfect; no packets are lost due to bit errors. An Aloha protocol is used to access the medium by the BS and users. The users generate traffic following Poisson distribution, with frame generation rate lu. The time duration of data frames is Tf whereas the duration of acknowledgements is TAck: Determine the probability that the frame generated by a user will be lost.
