The TCP Vegas implementation is buggy, and BIC is too agressive
so they should not be in the default list. Westwood is okay, but
not well tested.

Since no one really agrees on the relative merits and problems of the
different algorithms and since the users themselves dont know, dont care
and have no clue on what should be the correct behaviour to report bugs
(see the old bic bugs, the htcp bugs, the recent sack bugs) I would
suggest to avoid making the whole internet a guinea pig and get back to
reno. If someone really needs to push high BDP flows he should test it
himself and choose what works for his kernel at the time.

For myself and anyone who asks me I recommend to set the default to
reno. For the few who really need high speed flows, they should test
kernel and protocol combination.

I agree wholeheartedly with Baruch. If we are going to remove BIC as
default we should go back to Reno as Cubic is even less tested in
production use than BIC.

Unless of course the papers you saw at PFLDNET showed that Cubic was a
really good choice and you want to point us to those papers.
