7. A UCF student is sending a packet of size 10 KB to another student in MIT using Router U in UCF side and Router M in MIT side. Assume that Router U and Router M are directly connected to each other via a fiber optic cable which is 1,000 km long. Further assume that the Router U's outgoing link has a capacity of 5 Gbps and light travels at speed 300*106 m/s. Please answer the following questions. Show your work. [Note: K is 1,000 when it is used for "bits (e.g., 2 Kb = 2,000 b) or standalone (e.g., 2 K = 2,000). But, when it is used with bytes, it is 1,024, e.g., 2 KB = 2,096 B.] i. (6 points) What is the packet transmission delay? ii. (6 points) What is the propagation delay between the routers? iii. (6 points) To keep the total end-to-end delay less than 10 ms, what should be the maximum total for the nodal and queueing delay? iv. (6 points) Assume, instead of a regular fiber optic cable, a hypothetical medium has been used between these two routers, which can carry packets at a speed 600*106 m/s. Now, if UCF reduces Router U's outgoing link capacity to 1 Gbps, is it possible that the first bit of the 10 KB sized packet will reach to Router M even before the last bit of the packet has left UCF?
