Suppose two nodes, A and B, are attached to opposite ends of a 900 m cable, and that they each have one frame of 1000 bits (including all headers and preambles) to send to each other. Both nodes attempt to transmit at time t0. Suppose there are four repeaters between A and B, each inserting a 20-bit delay. Assume the transmission rate is 10 Mb/s, 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 and the 96-bit time delay. What is the one way propagation delay (including repeaters delays) between A and B in seconds? Assume the signal propagation speed is 2*10^8 m/s At what time in seconds is A's packet completely delivered at B?
