Re: Questions about Internet Packet Losses

  The 4.3 Reno-derived TCPs (the majority) are fairly robust.

Yeah, but I doubt that they're in the majority.  Recent stats indicate that
about 9% of the packets out there are using an MSS of 512.  Another 1% are
using an MSS of 256.  Only 6% are using 536, and 7% are using 1460.  This
indicates to me that there are a whole lot of broken boxes out there still.

I'm wondering why.  The easiest way to implement TCP stack always was
to pull the pieces off BSD code.  Even oldest MS-DOS TCPs (like Phil
Karn's KA9Q) are essentially that.
