6. Suppose two nodes, A and B, are attached to opposite ends of an 800 m cable, and that they each have one frame of 1,500 bits (including all headers and preambles) to send to each other. Both nodes attempt to transmit at time t=0. Suppose there are four repeaters between A and B, each inserting a 20-bit delay. Assume the transmission rate is 100 Mbps, and CSMA/CD with backoff intervals of multiples of 512 bits is used. After the first collision, A draws K=0 and B draws K=1 in the exponential backoff protocol. Ignore the jam signal and the 96-bit time delay. (a) What is the one-way propagation delay (including repeater delays) between A and B in seconds? Assume that the signal propagation speed is 2.108 m/sec. (b) At what time (in seconds) is As frame completely delivered at B? (c) Now suppose that the repeaters are replaced with switches/routers. That is, each switch incurs a store-and-forward delay in addition to the 20-bit time delay. Also, suppose that only A has a frame to send to B (that is, no collision). At what time, in seconds, is A's frame delivered at B? Note that since no collision, we are calculating the delay for the first and only one frame.
