Problem I Consider two hosts, A and B, connected by a single link of rate R bps. Suppose that the two hosts are separated by m meters, and suppose the propagation speed along the link is s meters/s. Host A is to send a packet of size L bits to host B. a. Express the propagation delay, d prop, in terms of m and s. b. Determine the transmission time of the packet, depans, in terms of L and R c. Ignoring processing and queuing delays, obtain an expression for the end-to-end delay. d. Suppose Host A begins to transmit the packet at time t = 0. At time t = d trans , where is the last bit of the packet? e. Suppose drop is greater than dorang. At time t = d pans , where is the first bit of the packet? f. Suppose d prop is less than dorang. At time t = derans, where is the first bit of the packet? g. Suppose s = 2.5x109, L = 100 bits, and R = 28 kbps. Find the distance m so that d prop equals d trans
