The basic TBF-type policer is pretty = crap; really not hard to do better if you bother to think about it. I'm still not *entirely* convinced that we can't have real DRR++/Codel = implementations at line rate in hardware. I think nobody has even = seriously tried to do it. Getting to that point would potentially = obsolete policers overnight, at least from a theoretical point of view. Meanwhile, we can still do a lot at the gigabit-per-subscriber level in = software. - Jonathan Morton
