Hi all cbq guru,
In my network BW measurement, it seems that the class type "isolated"
doesn''t work.
Supposedly, "isolated" class means it neither share other''s
BW nor share its
BW to other. The simple network is as follows:
root (1:0)
|
parent (1:1) --BW 10Mbit
/\
/ \
/ \
child1 (1:2) child2 (1:3)
BW 5Mbit BW 5 Mbit
isolated isolated
But according to measurement, child2 class can still get 10 Mbit if child1
class is idle.
Do I misunderstand the meaning of "isolated" or does it don''t
work.
Does any guru find the same problem? Please give me some comment if you
know the answer.

"isolated" means other classes cannot borrow bandwidth from you, "bounded" means you cannot borrow bw from other classes.

However, from the results, child2 class can borrow bw from child1 class. Have you the same results?
