[LARTC] Leaky bucket in TC

[LARTC] Leaky bucket in TC

[Fatih Düzova]

Hi, 
I am trying to control bandwidths of the connections by using TC with
HTB. But I want to implement Leaky Bucket on this structure so as to
have a straight flow.
Due to being new in this area, could anyone help me how I could do this? 
Does TC support leaky bucket? 

Best regards,
 
Fatih Duzova

if by "leaky bucket" u mean "drop everything above a certain rate" then htb 
can do this as a part of normal operation.

Thank you for your response,
My aim is to define a bandwidth (i guess it can be done by defining
equal rate and ceil values), and not to allow to pass this value "at
any moment" during the connection.  Is htb able to do this job, for
instance in the simple example below?


tc qdisc add dev ath0 root handle 1:0 htb default 15
tc class add dev ath0 parent 1:0 classid 1:1 htb rate 240kbit

tc class add dev ath0 parent 1:1 classid 1:5 htb rate 72kbit ceil 72kbit
tc class add dev ath0 parent 1:1 classid 1:10 htb rate 120kbit ceil 120kbit
tc class add dev ath0 parent 1:1 classid 1:15 htb rate 48kbit ceil 48kbit

tc qdisc add dev ath0 parent 1:5 handle 5:0 sfq perturb 10
tc qdisc add dev ath0 parent 1:10 handle 10:0 sfq perturb 10
tc qdisc add dev ath0 parent 1:15 handle 15:0 sfq perturb 10

tc filter add dev ath0 protocol ip parent 1:0 prio 1 u32 match ip
dport 22 0xffff flowid 1:5
tc filter add dev ath0 protocol ip parent 1:0 prio 1 u32 match ip
sport 22 0xffff flowid 1:5
tc filter add dev ath0 protocol ip parent 1:0 prio 1 u32 match ip
dport 80 0xffff flowid 1:10
