This problem begins to explore propagation delay and transmission delay, two central concepts in data networking. Consider 2 hosts, A and B, connected by a single link of rate R bps. Suppose that the 2 hosts are separated by m meters, and suppose the propagation speed s along the link is in meters/sec. Host A is to send a packet of size L bits to Host B. A. Express the propagation delay, dprop, in terms of L and R.
B. Determine the transmission time of the packet, dtrans, in terms of L and R.
C. Ignoring processing and queuing delays, obtain an expression for the end-to-end delay.
D. Supose Host A begins to transmit packet at time t = 0. At time t = d(trans) where is the last bit of the packet. E. Suppose d(prop) is greater than d(trans). At time t = d(trans)where is the first bit of the packetF. Suppose d(prop) is less than d(trans). At time t = d(trans) where is the first bit of the packetG. Suppose s = 2.5* 10 power(8), L = 100 bits and R = 28 kbps. find thedistance m so tha d(prop) equals d(trans).
