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. a. Express the propagation delay, ????? , in terms of m and s. b. Determine the transmission time of the packet, ?????? , in terms of L and R. c. Ignoring processing and queuing delays, obtain an expression for the end to-end delay

Question

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.
a. Express the propagation delay, ????? , in terms of m and s.
b. Determine the transmission time of the packet, ?????? , in terms of L and R.
c. Ignoring processing and queuing delays, obtain an expression for the end to-end
delay
