Hello,
Let's say that my ISP gives me 5000Kbit guaranteed bandwidth. I'm
starting a HTB traffic shape like this:
tc qdisc add dev eth1 root handle 11: htb default 99
tc class add dev eth1 parent 11:0 classid 11:1 htb rate 10000Kbit burst
ceil 10000Kbit prio 0
tc class add dev eth1 parent 11:1 classid 11:2 htb rate 5000Kbit ceil
5000Kbit prio 5
[here I have a lot of sub-classes that borrow from parent 11:2]
I'll let HTB to automatically compute the values for 'burst' and
'cburst'. The problem is elsewhere. What are the correct values for
'rate' and 'ceil' of 11:2 class in this case? In fact, total value of
'ceil's from all sub-classes exceeds 5000Kbit, so there are moments when
the bandwidth that comes from my ISP is bigger than guaranteed bandwidth.
Is there some kind a theory that says how to establish the values of
'rate's and 'ceil's from the parent and its sub-classes?
TIA.
