This elementary problem begins to explore propagation delayand transmission delay, twocentral concepts in data networking. consider two hosts a andb, connected by a single link ofrate r bps. suppose that the two hosts are separated by mmeters, and supose the propagation speedalong 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).
