. Suppose nodes A and B are on the same 10 Mbps Ethernet bus, and the propagation delay between the two nodes is 245 bit times. Suppose A and B begin transmission at t 0 bit t lisions att 245 bit times. Assume that a jam signal is of length 48 bit times and they finish transmitting this jam signal at t 24548 293 bit times. Since there is a collision, A and B choose different values of K in the CSMA/CD protocol. Suppose that KA0 and K1. Provide a time line showing the following events: times. They both detect co Time that A begin retransmission Time that B schedules its transmission. Times that A's signal reaches B Also, answer the following questions o Does B refrain from transmitting at its scheduled time? e Can the retransmission from A and B above collide? Justify your answers
