A path in a digital circuit-switched network has a data rate of 1 Mbps. The
exchange of 1000 bits is required for the setup and teardown phases. The distance
between two parties is 5000 km. Answer the following questions if the
propagation speed is 2 × 108 m:
a. What is the total delay if 1000 bits of data are exchanged during the datatransfer
phase?
b. What is the total delay if 100,000 bits of data are exchanged during the
data-transfer phase?
c. What is the total delay if 1,000,000 bits of data are exchanged during the
data-transfer phase?
d. Find the delay per 1000 bits of data for each of the above cases and compare
them. What can you infer?

 

someone please explain the meaning of last part (d)
