Roughly speaking, an active conntrack entry is a flow that has sent at least a packet within the last minute or so, while a congestion-limited flow is one that sends data as fast as it reasonably can. I certainly hope you don't have 142 congestion-limited flows on an idle router. > I still think that for VoIP prioritizing might still be required > until supplied minimum bandwidth gets higher. I agree, in the short term. In the medium term, I'm optimistic we can get rid of these nasty hacks, which is why I'd rather see Dave spend his copious free time on something else. > Even at 1000 symmetric I still think it would be a good idea to > isolate really latency critical traffic from the rest, It would certainly be good to have hard data rather than confronting your intuitions with my back-of-the-envelope computations.
