Hello all, I'm wondering if there's some data on Codel with low shape rates?
In particular, I'm talking about in the kbps ranges. In my investigation, it seems as though the algorithm can't control latency as effectively. For one, the algorithm requires 2 packets in the queue to operate, but at a low shape rate, it's highly likely that all packets in the queue will have high latency, so 'count' will begin to ramp up... but conversely, it's also likely that we drain the queue, and then leave the drop state (and wont re-enter it for at least an interval's worth of time (100ms)). Effectively, we get an oscillation of "in drop state, out of drop state", and we're not in the drop state for long enough to ramp up count, because the queue itself (proportional to the shape rate) isn't very big. Are there way to combat this, or am I misinterpreting a portion of the algorithm?
