Re: [LARTC] IP based bandwith limit

[Christoph Petersen <lists@peterschen.de>]

Hi,

unfortunately there is only one interface for the customers. My problem 
is to limit the up AND down speed in dependence to each other.

So customer A get a bandwith of 2Mbit this is up AND down so if he 
downloads with 1Mbit he gets a max upload speed of 1Mbit.

I've tried it with htb like this:

#!/bin/sh
TC=/sbin/tc
DEV=eth0

$TC qdisc add dev $DEV root handle 1 htb default 90
$TC qdisc add dev $DEV handle ffff: ingress
$TC class add dev $DEV parent 1: classid 1:2 htb rate 100Mbit burst 6k

$TC class add dev $DEV parent 1:2 classid 1:10 htb rate 10kbps ceil 10kbps
$TC filter add dev $DEV parent 1:0 protocol ip prio 100 u32 \
    match ip dst 192.168.1.19 \
    classid 1:10

$TC filter add dev $DEV parent ffff: protocol ip prio 50 u32 \
    match ip src 192.168.1.19 \
    police rate 10kbps burst 10k drop flowid 1:10

this is my internal test. But it wouldn't work with dependence to each 
other...
