Question: Consider two hosts A and B separated by 2 nodes (switches or routers). Host A wants to send a file of size M = 15

Consider two hosts A and B separated by 2 nodes (switches or routers). Host A wants to send a file of size M = 15 Mbytes over to host B. Each link has the same data rate C = 12 Mbit/s. a) Assume "message" switching, how long would it take for the whole file to be received by host B? Write the formula giving the time in terms of C, M, and possibly other parameters and explain your assumptions (note: M and C are in different units).

b) Assume packet switching and that all packets have the same size L = 9600 bits, how long would it take for the whole file to be received by host B? Explain your assumptions. Write the formula giving the time in terms of C, M, and possibly other parameters
