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. Baruch
