[altq 1153] Re: ECN implementation
A couple of months sound a little bit long to me. Could you
explain briefly what are the issues with the current (or old?)
ECN implementation in ATLQ?
I wouldn't mind doing the implementation myself but would like
to avoid duplicate effort if possible. And I'm only interested
in having ECN in FreeBSD 4.3.
I've implemented the PI controller  and Gentle RED  in the
framework of ALTQ. Although these AQM schemes don't require
end systems to be ECN capable, I thought it would be interesting
to see how AQMs perform when end systems are ECN capable.
