I think there are people in this list that should be able to answer to
this question better than me.
AFAIK the process is complex because even vendors use network processors
they don't build and
traffic management is developed by the chipco in the chip. Especially
for the segment we are considering here.
In the end the dequeue process is always managed by someone else and
mechanisms and their implementations opaque.
You can do testing on the equipment and do some reverse engineering.
What a waste of time...
This is why single queue AQM is preferred by vendors, because it does
not affect current product lines
and the enqueue is easier to code. FQ requires to recode the dequeue or
to shadow the hardware dequeue.
My experience is not based on providing a requirement document, well we
tried that first,
but on joint coding with the chipco because you need to see a lot of
chip internals.
