This elementary problem begins to explore propagation delayand transmission delay, two central concepts in data networking. Consider two hosts A andB, connected by a single link of rate R bps. suppose that the two hosts are separated by mmeters, and supose the propagation speed along the link is s meters/sec. Host A is to send a packet ofsize L bits to Host B. a. Express the propagation delay d(prop) interms of L and R. b. Determine the trnasmission time of the packet d(trans) in termsof L and R. c. Ignoring processing and queing delays obtain an expression forthe end to end delay. d. Supose Host A begins to transmit packet at time t=0 . At timet=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) whereis the first bit of the packetg. Suppose s=2.5* 10power(8), L=100 bits and R=28 kbps. find thedistance m so tha d(prop) equals d(trans).
