Assuming a call setup time of 0.5 second for a circuit switching scheme, what are the total
Â
data transfer times when 4064 bits of data must be required to be transferred from station A to
Â
station B with
Â
a) circuit switching, and
Â
b) datagram packet switching?
Â
The stations are separated by 5 hops (1 hop = 10 km), the signal propagation speed is 1000 km/
Â
sec and the line capacity for each hop is 9600 bps. Assume that each packet is 1024 bits long
Â
with only 8 bits of overhead.
