We are sending a packet of length 2,000 bytes from a source host to a destination host. Suppose only one link between source and destination has a transmission rate of 5 Mbps.

a). In the packet switching method, what is the transmission delay it takes a packet of length sent from source to destination?

b). In the circuit switching method, suppose there are 5 FDM channels in the link. The packet was sent over one of the channels. What is the end-to-end delay including 100 ms to establish the end-to-end circuit?
