Based on the following statement "The end$-$to$-$end delay for circuit switching and datagram packet switching can be calculated by adding the call setup time, message transmission time, and propagation delay over all hops. The time to transmit a message is determined by the message's length divided by the data speed, while the propagation delay over all hops is the number of hops multiplied by the propagation delay per hop. The end$-$to$-$end delay for circuit switching is $0\mathrm{.}537$ seconds, while for datagram packet switching it is $0\mathrm{.}448$ seconds.", discuss your observation about delay in circuit switching vs delay in packet switching.
