Question

3. A company has circuit and packet switch networks each having a capacity of 450Mbps.Users of both networks each require 30Mbps when transmitting. Users of the packet switching network only transmit 10% of the time

a. What is the maximum number of circuit-switched users that can be supported? Explain your answer.

b. Suppose there are 18 packet-switching users. Can this many users be supported under circuit switching? Explain.

Answer 1

--> A company has circuit and packet switch networks each having a capacity of 450Mbps.

--> Users of both networks each require 30Mbps when transmitting.

a) The maximum number of circuit-switched users that can be supported :

           450 / 30

         = 15

So, 15 users can be supported maximum at a time.

b) 18 users cannot be supported under circuit switching.

Because 18*30 = 540 > 450 Mbps which is network capacity.
