- Which of the following statements is/are correct?I. The fragmentation is applicable for data in the datagram but not for header.II. Reassembly of the fragments must be performed at the destination because,theIntermediate networks may have different maximum transmission unit (MTU) sizes.III. In the IP header, the time-to-live (TTL) field is invariable. (A) I and II(B) I and III(c) II and III(D) All are correcta) In a bus CSMA/CD network with a data rate of 10 Mbps, a collision occurs 20 µs after the first bit of the frame leaves the sending station. What should the length of the frame be so that the sender can detect the collision? b) There are only two stations, A and B, in a bus 1-persistence CSMA/CD network with Tp = 25.6 µs and Tr = 51.2 µs. Station A has a frame to send to station B. The frame is unsuccessful two times and succeeds on the third try. Draw a flowchart for this problem. Assume that the R is 1 and 2 respectively and ignore the time for sending a jamming signal.Match the left-column statements to the right-column architecture. A server is constantly on. Processes may serve each other. Communication always involves client and server processes. HTTP employs this architecture. Users control hosts, which may go down unexpectedly. Self-scalable. Answer: peer-to-peer. B. Peer-to-peer. Peer-to-peer or client-server. Client-server D. TCP/IP design.

Most IP datagram reassembly algorithms have a timer to avoid having a lost fragment tie up reassembly buffers forever. Suppose a datagram is fragmented into four fragments. The first three fragments arrive, but the last one is delayed. Eventually the timer goes off and the three fragments in the receiver's memory are discarded. A little later, the last fragment stumbles in. What should be done with it?Most IP datagram reassembly algorithms have a timer to avoid having a lost fragment tie up reassembly buffers forever.

- Consider a web page whose base file is of size S1 = 10 KB. Assume that the web page consists of N = 20 inline objects each of size S2 = 100 KB. Assume that the round-trip time to the web server is T = 100 ms and the bottleneck capacity is C = 10 Mbps. Ignore any packetization delays and header overhead.a. Assuming non-persistent HTTP is used with a single TCP connection, how long does it take to download the web page?b. Assuming non-persistent HTTP is used with 4 parallel TCP connections, how long does it take to download the web page?c. Assuming pipelined, persistent HTTP is used, how long does it take to download the web page? ”Pipelined” means requests for multiple objects can be sent back-to-back on the same connection.d. Assuming non-pipelined, persistent HTTP with 2 parallel TCP connections is used, how long does it take to download the web page? Assume that the 2 parallel connections equally share the total available bandwidth C.True or false 9. Suppose host A sends host B one segment with sequence numbers 38 and 4 bytes of data. Then in this same segment, the acknowledgment number is necessarily 42. 10. Suppose host A is sending a large file to host B over a TCP connection. If the sequence number for a segment of this connection is m, then the sequence number for the subsequent segment will be m + 1. 11. Host A is sending host B a large file over a TCP connection. Assume host B has no data to send A. Host B will not send acknowledgments to host A because host B cannot piggyback the acknowledgments on data. 12. Consider an HTTP server using persistent connections. Suppose the server spawns a sep- arate process for each client that connects to the server. Then each of these spawned pro-cesses will have different server port numbers.Consider sending a 1300-byte datagram into a link that has a MTU of 500 bytes. Which of thefollowing is true? Please justify your answer.1. Three fragments are created with offsets 0, 500/8 1000/82. Three fragments are created with offsets 0, 480/8 and 960/8.3.
