 === Faulty Hardware Link Detection ===

+A bad cable (faulty hardware link) is detected when all of the following  
conditions are met:
+ * 100 divided by the total test time in seconds and multiplied by the  
proportion of the number of multiplicative downward congestion window  
adjustments to the total number of segments *is greater than 15*
+ * The proportion of the cumulative time spent in the 'Congestion Limited'  
state to the total test time divided by the total test time in seconds *is  
greater than 0.6* (*WARNING: this condition cannot be met*)
+ * The proportion of the number of multiplicative downward congestion  
window adjustments to the total number of segments sent *is less than 1%*
+ * The maximum slow start threshold, excluding the initial value, *is  
greater than 0*
