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 packet switch, what information in the packet does the switch 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?
Consider given data:
Suppose end system A wants to send a large file to end system B.
The following steps to end System A creates packets from the file at very high level:

The following information in the packet does the switch use to determine the link onto which the packet is forwarded:

The following the packet switching in the Internet analogous to driving from one city to another and asking directions along the way:
