Suppose that Bob sends N back-to-back packets, each of length L bits, to Alice over 3 links (shown below). Suppose that the transmission rate of each link is R bits/sec. What is the end-to-end delay of sending all packets to Alice? Note, consider only the transmission delay that occurs in sending packets. Show the steps used for derivation Alice Rbps Rbps In our home networks, as well as in other kinds of networks, computers are connected to a modem. Explain why
