What would be nice is if you could document what happens when
a) child ceil > parent ceil
b) child rate > parent ceil
c) child ceil > parent rate
d) child rate > parent rate
How does this influence the shaping results and the shaping of other
classes? I've actually asked a similar question before: If you have
1:1
/ \
/ \
1:2 1:3
/|\ \------
/ | \ \ \
1:4 1:5 1:6 1:7 1:8
if 1:7 and 1:8 respects the rate/ceil of 1:3 and 1:3 respects the rate/ceil
of 1:1, but 1:4 does not respect the rate/ceil of 1:2 and 1:2 respects the
rate/ceil of 1:1, does the shaping of 1:3 work as normal and only those
classes under 1:2 are adversely affected or not? from your previous answer,
it seems that the classes under 1:3 would not be affected, but I would love
to know why. what happens with 1:4 requests some bandwidth which 1:2 does
not have...
