Two nodes (A and B) are on the same network, and distanced by 500-meter. The two nodes are connected via 3 switches, each with a delay of 5 µs. Suppose that both of A and B transmit 1500 bytes at the same exact time and their frames collide. A chooses to retransmit immediately after jam signal is received, and B chooses to retransmit after 50 µs of receiving the jam signal. Assume the transmission speed is 10 Mbps, the channel is CSMA/CD with backoff intervals that are multiples of, the jam signal takes 10 µs to transmit, and the inter-frame gap is 9.6 µs. Find the time required to deliver A’s packet to B
