Hello I am using htb (krenel 2.6.14.3 + esfq patch from fatooh.org) to limit the bandwidth. But I want the absolute maximum rate to be for example 5Mbit and not to exceed it. here is the script: $tc qdisc add dev ${NETIF} root handle 1 htb r2q 4 $tc class add dev ${NETIF} parent 1: classid 1:21 htb rate 5Mbit ceil 5Mbit $tc class add dev ${NETIF} parent 1:21 classid 1:101 htb rate 2Mbit ceil 5Mbit prio 1 $tc class add dev ${NETIF} parent 1:21 cla...

Hi all, I have an average 2mbit multicast stream that once in a while bursts high (up to 20mbit/s) in short periods (about 200ms). Could anyone please help me with directions using tc for configuing leaky bucket shaping to this stream? I have a 5mbit/s ceiling. My system is running gentoo linux 2.6.14, and I have compiled in all QoS modules. Thanks. Oivind

Hi, I'm looking for a good way to create a constant data stream that will occupy a bandwidth of about 2--5Mbit/sec between two remote hosts over the internet. I have full access to the hosts involved. My first attempt to use scp to copy data from /dev/null on host A to /dev/null on host B, but scp says '/dev/null: not a regular file'. If something like that would work, I would be able to limit...

Hello, I need to do the following: make a htb qdisc with its class of 70mbit then add some classes, one of 10mbit, another of 10mbit, one of 5mbit and the rest in last class (with also child classes). The 5mbit class is a quaranteed one, and it is marked with a special dscp. I will add an HFSC qdisc on this one, and then several classes to it. When i add filters, what should i use as parent to say the traffic should go to a HFSC class inside...

Dear Community, sorry for the somewhat dumb question. Maybe someone has any pointer to how to setup the RED queue to mark pakets with ECN. In particular what are appropriate parameter settings for limit, min, max, etc. All my trials end up with either "RTNETLINK answers: Invalid argument", although the command line (at least for me) looks fine in regard to what is said on the

Hello! I need to switch from htb2 to htb3, because of speed issues (for me, htb2 is unable to handle more then 100mbit duplex with ~550 classes), kernel profiling shows htb_dequeue_prio at 1st place with 3x isolation. So, I''ve moved from 2.4.19 to 2.4.25 kernel (hi-pac for classification/marking and htb3 for queueing), and traffic rate drop from 100 to 20mbit. What can be wrong? The

Hi there, I am experiencing some issue with X-Lite. When I am calling over the phone thru my PSTN-to-VoIP gateway internationally using G.729 the quality is just perfect. When I am using X-Lite to connect the same box, and then to call internationally - I am experiencing some issues. I have 5Mbit/800Kbit cable link with average 60 msecs to my VoIP box. The transfer rate is never falling below 500Kbytes/sec. Therefore I am not suspecting quite noticeable packet loss. I enabled G.711 ulaw, alaw and speex codecs on both sides. By playing with different codecs I am trying to avoid some clicki...

...ous message I mentioned "rate", but I didn''t pay attention that ceil gets set automatically to the same value you set in "rate") when you set ceil 128kbit, you start with 128kbit bandwidth, and it goes up to 1mbit, if you set 1mbit, it starts with 1 mbit and goes up to 5mbit any comments? can someone verify? how can I debug this? best, --alex

Here''s the scenario: - 4 NIC''s; 1 Upstream, 3 subscribers each with different rates. NIC-1: NO CAP simply 100mbit I want to cap the traffic on each of the subscriber NIC''s to a specific rate i.e.: - NIC-2: 8mbit - NIC-3: 5mbit - NIC-4: 3mbit Just to summarize, ALL I''m trying to do is limit the bandwidth on each NIC (ingress & egress) whether it is 10/100/1000Base-T. Right now I am using a Cisco using rate-limiting which is very simple. I''d like to perform this task on Linux box for easier scali...
