I am trying to build a Linux router that simply throttles everything down to certain bandwidths. That is, no priority queuing ...etc, just slow all traffic down to the specified rates, which are 64,128,256,512 kbit. We want to setup the bandwidth on the router, then pump a known load from an application through the router and see how that behaves over various link speeds. (we are in a lab environment)
Using the htb qdisc with ceil equal to rate ought to accomplish this.
I thought the same thing, so far so good.
Using kernel 2.6.5-1.358 I simply used these commands from Stef's version of tc from docum.org, module sch_htb is loaded.
tc qdisc add dev eth0 root handle 10: htb tc class add dev eth0 parent 10: classid 10:1 htb rate 64kbit ceil 64kit
You need to classify your traffic.
tc qdisc add dev eth0 root handle 10: htb default 10 tc class add dev eth0 parent 10: classid 10:1 htb rate 64kbit ceil 64kit
If you add the default parameter, htb will put any unclassified into classid 10:1.
That makes sense.
Ok, so I have to classify my traffic before this will route them throu the qdisc. Are you taking about classifying via iptables?? I thought that was optional, more for filtering ...etc.
I thought that would do the job, but my testing from uploading files via ftp to another box, show nothing gets shaped.
Right, because it wasn't classified.
