- Ahem.

- Although I agree that my stuff isn't designed to run efficiently under
- UNIX, I beg to differ about the "quality" of the implementation. I've
- long had all the same stuff in my TCP/IP and SLIP that Berkeley has:
- VJ header compression, VJ srtt/mdev rto calculation, clamped
- retransmission backoffs, slow start, fast recovery, Nagle tinygram
- avoidance, etc. It's fast enough to never be the bottleneck on a FTP
- (as opposed to the wire or the disk.) And it has avoided many of the
- problems that still nag the descendants of some previous Berkeley
- TCPs, like closing all TCP connections to a given host whenever you
- receive ANY ICMP message that references that host...
