[e2e] OS Implementation of Byte Counting during Congestion Avoidance

[Salman Abdul Baset]

I was wondering if OSes implement byte counting during congestion
avoidance. From my investigation it appears:

1) Linux
   2.6.16 and higher implement RFC 3465 Appropriate Byte Counting during
   slow start. However, it does not implement byte counting during
   congestion avoidance.

2) Windows XP
   Does not implement byte counting during slow start and congestion
   avoidance.

3) Windows Vista
   Will implement RFC 3465 which means byte counting during slow start.
   Not sure about byte counting during CA.

3) MacOS, FreeBSD, OpenBSD?
   Does anyone who uses these OSes know if they implement byte counting
   during slow-start and congestion avoidance?

Thanks
