Problem # 1 (26 points): Consider the following exchange of Ethernet frames between nodes A and B over the same Ethernet segment. Assume the propagation delay between the two nodes is 150 bit times, and that both A's frame and B's frame have a size equal to 576 bits Host A time (bit times) Host B time (bit times) 4 Is 1. (2 points) Based on the exchange displayed above, and assuming that the collision between the frames sent by A and B occurs for the first time, find the exponential backoff values selected by A and B (i.e., Ka and KB). Justify your answer 2. For each of the following, calculate the exact time (in bit times) when: a) (2 points) B senses a collision (i.e., ti) b) (5 points) The last bit of A's jam signal reaches B (i.e., h) c) (2 points) B starts retransmission of the frame (i.e., t) d) (5 points) The last bit of B's retransmitted frame reaches A (i.e., A). e) (6 points) A finishes the exponential backoff period and checks if it can retransmit f) (2 points) A starts retransmission of the frame (i.e., ts) g) (2 points) The last bit of A's retransmitted frame reaches B (i.e., to).
