analysis
Circuit switching
The total delay of circuit switching is equal to the circuit setup time S, plus the X-bit transmission delay x/b.
Add the propagation delay kd of the signal on the K-segment link.
Packet switching
p/b is the transmission delay of 1 packet, X/P is the number of packets, K is the number of links, then (K-1) is the number of forwarding.
Kd is the propagation delay of the K segment link.
