CSMA/CD Performance

Efficiency= Max throughput/Line rate = P/(P+2?/A) Where, P = Frame time? = one-way propagation delayA = P[only one station transmits during a slot ] = fn{# of stations trying to transmit} = 1/e for infinite stations

Efficiency = 1/(1+2?/A)Where ? = Propagation delay/Frame time= (Distance/Speed of signal)/(Frame size/Data rate)= (Distance ×Data Rate)/(Frame Size × Signal Speed)
