client, and there is no other traffic on this path. Assume each packet of size L bits, and both links have the samepropagation delay dprop- (a) What is the packet

inter-arrival time at the destination? That is, how much time elapses from when the lastbit 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., RcjRs). Is it possible that the second packetqueues at the input queue of the second link? Explain. Now suppose that the server sends the second packetT seconds after sending the first packet. How large must T be to ensure no queuing before the second link?Explain. Consider the figure (a) below. Assume that we know the bottleneck link along the path from the server to theclient is the first link with rate Rs bits/sec. Suppose we send a pair of packets back to back from the server to the
