17824 bits of data is to be transferred from a station A to station B. Assume a call setup time of 0.01 seconds for a switching network. Calculate the total data times needed when the following switching technologies are used: (a) Circuit switching; (b) Virtual circuit and datagram packet switching. The stations are separated by 3 hops (1 hop=4km), the signal propagation speed is 2000 km/s and the line capacity for each hop is 2400bps. Assume that each packet is 512 bits long with only 12 bits of overhead.
