Question: Consider Figure 1.19(a). Assume that we know the bottleneck link along the path from the server to the client is the first link with rate

Consider Figure 1.19(a). Assume that we know the bottleneck link along the path from the server to the client is the first link with rate R_sbits/sec. Suppose we send a pair of packets back to back from the server to the client, and there is no other traffic on this path. Assume each packet of size L bits, and both links have the same propagation delay d_prop.

a. What is the packet inter-arrival time at the destination? That is, how much time elapses from when the last bit of the first packet arrives until the last bit of the second packet arrives?

b. Now assume that the second link is the bottleneck link (i.e., R_c < R_s). Is it possible that the second packet queues at the input queue of the second link? Explain. Now suppose that the server sends the second packet T seconds after sending the first packet. How large must T be to ensure no queuing before the second link? Explain.
