Question: Consider two hosts A and B connected by N routers (total of N+1 links) in a packet-switched datagram network. Each link transmits at R.bps.

Consider two hosts A and B connected by N routers (total of N+1 links) in a packet-switched datagram network. Each link transmits at R.bps. The length of each link is d, and the propagation speed of the medium used is s. We are trying to send a message of Mx L bits (M packets of L bits) from A to B as efficiently as possible. Assume that there is a negligible processing delay at each router. If the network used is a packet-switched datagram network with a queueing delay of seconds per packet at each router (on the average), how long will it take to send the message (of M packets of L bits each) from A to B?
