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 Suppose that the two hosts are separated by m meters, and suppose the propagation along the link is s meters/sec. Host A is to send a packet of size L bits to Host B.
1. Express the propagation delay, dprop, in terms of m and
2. Determine the transmission time of the packet dtrans, in terms of L and
3. Ignoring processing and queuing delays, obtain an expression for the end--‐to--‐ end delay.
4. 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. Suppose dprop is greater than dtrans. At time t=dtrans, where is the first bit of the packet?
6. Suppose dprop is less than dtrans. At time t=dtrans, where is the first bit of the packet?
7. Suppose s=2*10⁹, L=1024 bits, and R=256 Find the distance m so that dprop equals dtrans.
