The CoDel control_law is defined as 't + interval/sqrt(count)'
The sample implementation
The CoDel control_law is defined as 't + interval/sqrt(count)'
The sample implementation (http://queue.acm.org/appendices/codel.html) suggests
that sqrt(count) can be calculated using only integer multiplication, but I'm
wondering if it even needs to be calculated.
Would it not be more
The version of codel that cake uses does indeed use such a lookup table for
1..15. This was for accuracy rather than performance reasons.
