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?
