Midterm Solution Sketch Student’s Last Name: Student’s First Name: UCINETID: Seat: Problem # Points Out of Total 1 30 2 40 3 30 Total 100 Academic Honesty Policy: I agree to abide by th... e UCI Academic Senate Policy on Academic Honesty (Appendix VIII.B), which specifies that students have responsibility for: 1. Refraining from cheating and plagiarism. 2. Refusing to aid or abet any form of academic dishonesty. 3. Notifying professors and/or appropriate administrative officials about observed incidents of academic misconduct. The anonymity of a student reporting an incident of academic dishonesty will be protected. Student’s Signature: GOOD LUCK! 11. (30 Points) Packet Switching, Delay and Throughput. We are sending a 30 Mbit MP3 file from a source host S to a destination host D. All links in the path between source and destination have a transmission rate of 10 Mbps, unless otherwise noted (e.g., in question (g)). Packet switching is used unless otherwise stated (e.g., as in question (f)). Assume that the propagation speed is 2 · 108 meters/sec, and the distance between source and destination is 10; 000 km. (a) Initially suppose there is only one link between source and destination. Also suppose that the entire MP3 file is sent as one packet. The transmission delay is: 50 milliseconds 3.05 seconds X 3 seconds none of the above Solution: The transmission delay is DL = 30 10∗∗10 1066bps s = 3sec. (b) Referring to the above question, the end-to-end delay (defined from the time S starts transmitting the first bit, until D receives the last bit of the MP3 file) is 6 seconds 3 seconds X 3.05 seconds none of the above [Show More]
