Petr,
I have repeated the testing with WFQ in the class-default.
Class1---- > ping precedence 5 ---> 50% of bandwidth
Class2---> ping precedence 3 ----> 20% of bandwidth
Class default ---> WFQ ---> ping of other precedence
The results are the following:
If packets have a precedence of zero, they get no bandwidth.
However I increased the precedence to 4, the packets get about 1 K of
bandwidth.
I would have expected the default class to get at least 5% of bandwidth
remaining: that is 6.4 K
But this is not the case !!!!

Pierre, you asked an interesting question.
Actually, I still wonder how exactly class-default is assigned it's
weight...
It's been told in docs, that if you don't put a "banwidth" of "fair-queue"
in
class-default, it is treated as "best-effort".
That sounds to me "class-default" served after every other "weighted"
queue in that case. And it looks like it works that way, in your examples.
Well, if you do put "bandwidth" or "fair-queue", class-default
is being integrated into WFQ algorithm, and is served accordingly.
I would try to investigate that matter further :)
Petr
