Suppose two nodes, A and B are attached to the opposite end of a 1000 m cable, and that they have each a frame of 100 bits (include all headers and preambles) to send to each other. Both nodes attempt to transmit at time t = 0. Assume the transmission rate is 10 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 jamming signals and the 96 bit time delay.

a. What is the one way propagation delay between A and B in seconds? Assume the signal propagation speed is 2 is 2x108 ms-1

b. At what time (in seconds) is As packet completely delivered at B?
