Chapter 1, Problem P6P

This elementary problem begins to explore propagation delay and transmission delay, two central concepts in data networking. 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/sec. Host A is to send a packet of size L bits to Host B.

  1. a. Express the propagation delay, dprop, in terms of m and s.
  2. b. Determine the transmission time of the packet, dtrans, in terms of L and R.
  3. c. Ignoring processing and queuing delays, obtain an expression for the end-to-end delay.
  4. d. Suppose Host A begins to transmit the packet at time t = 0. At time t = dtrans, where is the last bit of the packet?
  5. e. Suppose dprop is greater than dtrans. At time t = dtrans, where is the first bit of the packet?
  6. f. Suppose dprop is less than dtrans. At time t = dtrans, where is the first bit of the packet?
  7. g. Suppose s = 2.5 · 108, L = 120 bits, and R = 56 kbps. Find the distance m so that dprop equals dtrans.
