Consider two hosts, 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/sec. Host A is to send a packet of size L bits to a) Express the propagation delay, dprop in terms ofm and s. b) Determine the transmission time of the packet, dran: in terms of L and R. c) Ignoring processing and queing delays, obtain an expression for the end to-end delay. d) Suppose Host A begins to transmit the packet at time -0.At time t-drans where is the last bit of the packet? e) Suppose apropis greater than drains. At time t=dmans, where is the first bit of the packet? f)) Suppose drop is less than dram-At time t=dmans, where is the first bit of the packet
