I'm currently writing some TCP-IP code (for a PDP-11 running RT-11), and am
looking to do retransmissions correctly.
>From what I've read here, poor retransmission behavior is a major source
of congestion... although my code is intended for a very lightly loaded
Ethernet and I can get away with being sloppy, if there's a painless way to
do it right for the general case, it would be nice to put it in.
I understand the idea of exponential backoff, and know of the RTT-based
algorithm suggested in the RFC (which I believe is what BSD 4.2 uses (?))...
is this the proper algorithm to use, or is there a better one?
Thanks for any info...
