Suppose Nodes A And B Are On The Same 20 Mbps Broadcast Channel With A Propagation Speed Of 2 2 108 M S Consider The Si 1 (112.46 KiB) Viewed 14 times

Suppose nodes A and B are on the same 20 Mbps broadcast channel with a propagation speed of 2.2×108 m/s. Consider the situation where A and B send Ethernet frames at the same time and they collide, and then A selects K=2 and B selects K=1 in the CSMA/CD retry mechanism. Further, assume that A and B are the only active nodes in the channel, and a 40-bit jamming signal and 96-bit time idle channel duration are used. a. Present a chart or table showing the timing sequence of events from the beginning A and B transmitting simultaneously to the successful retransmission from B to A without a collision. [10 marks] b. From the timing of events determined in a), calculate the maximum distance between A and B such that the retransmission from B to A does not collide. [5 marks]
