P4) Consider two hosts, A and B, connected by a single link of rate 5 Mbps. Suppose that the two hosts are separated by 1000 km, and suppose the propagation speed along the link is 2.5x109 meters/sec. Host A is to send a packet of size 500 bytes to Host B. 500 bytes 5 Mbps Host A Host B a) Computer the propagation delay, dprop: b) Computer the transmission time of the packet, durans c) Ignoring processing and queuing delays, compute the end-to-end delay: d) Suppose Host A begins to transmit the packet at time t 0. At time t- drans, where is the last bit e) Suppose dprop is greater than drans. At time t- drans, where is the first bit of the packet? f Suppose dprop is less than durans. At time t- drans, where is the first bit of the packet? g) Find the distance so that dprop equals dirans
