1. List four major components of a packet switch and their functions.
2. 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?
