1. Suppose end system A wants to send a large file to end system B. At a very high level, describe how end system A creates packets from the file. When one of these packets arrives to a router, what information in the packet does the router use to determine the link onto which the packet is forwarded? Why is packet switching in the Internet analogous to driving from one city to another and asking directions along the way?
1. Why will two ISPs at the same level of the hierarchy often peer with each other? How does an IXP earn money?
1. Suppose there is exactly one packet switch between a sending host and a receiving host. The transmission rates between the sending host and the switch and between the switch and the receiving host are R and R, respectively. If the switch uses store-and-forward packet switching, what is the total end-to-end delay to send a packet of length L? (Ignore queuing, propagation delay, and processing delay.)
1. A researcher wants to compare the performance of students living with their parents and
the performance of these students whose parents are working. Random samples were
taken from two normally distributed groups of population. 20 students who are living
with their parents posted an average grade of 89.25 with standard deviation of 2.4,
whereas the 15 randomly selected students whose parents are working abroad have an
average grade of 86.00 with standard deviation of 3.2. Test whether there is a significant
difference between the two groups of students at 0.05 level of significance.
