E.g. do they track the "base" backoff, and then multiply it by

1.5+random each time?



From http://kia.etel.ru/lib/Networking/kurose/ethernet/ethernet.htm but also seen on several other sites in more or less detail.

"Specifically, when transmitting a given frame, after experiencing the nth collision in a row for this frame, the adapter chooses a value for K at random from {0,1,2,...,2m - 1} where m:= min(n,10)."

Where K is basically the time to wait before retrying.
