similar to: TC (HTB) doesn''t work well when network is congested?

Hi all, Can you tell me where is the documentation for the new IFB (implemented in kernels > 2.6.16). Thanks in advance! Nikolay

With the below script, whenever I ping 10.0.16.10 (which matches the only filter I have), traffic still get''s sent to the default 1:2 class instead of 1:1 and I don''t know why... Any hints? (kernel 2.6.12, iproute2-2.6.15) tc qdisc del dev eth0 root > /dev/null 2>&1 tc qdisc add dev eth0 handle 1: root htb default 2 tc class add dev eth0 classid 1:1 parent 1: htb rate

Hi, What exactly are the "tokens"? I thought each token allowed the sending of one byte, that tokens are stored in a bucket that can hold a max of "burst" tokens, and that this bucket is filled with tokens at "rate". But theory does not seem to explain the "tc -s .." output in the examples below. And I can''t figure out why or how... #tc qdisc

Hello. I have a linux server connected to a gigabit lan, and though that lan to a 768kbps/768kbps DSL modem. I''m trying to shape my webserver running on port 80/443 down to 512kbps, while leaving all other ports alone. The current configuration script that I''m using is as follows: tc qdisc del dev eth0 root tc qdisc add dev eth0 root handle 1: htb default 99 tc class add dev

Dear all, I''m having real problems getting tc to do anything useful at all. I''m also under pressure to get this fixed before the students start arriving later this month (I work in a university). In short, I want each IP address to be hard limited to 128kbit down, 64kbit up, never to be allowed more bandwidth than this. It is also important that the latency remains

Eric, I''ve attached the output from the command you requested below. I''m using kernel 2.6.17.12 and tc version ss060323. I''m have a nforce4 onboard giggabit controller using the forcedeth driver, if that makes a difference. Charlie, I''ll take a look at the Apache model for throttling, thanks. I was going for tc because was going to try to add additional

Hi all, First, let me say I''ve been most impressed with how quickly and professionally people on this list ask and answer questions. Next, let me say that with which I need help is properly configuring strict PQ, and gathering certain stats. Specifically: - I need to create a priority queue with four queues (let''s say they are of high, medium, normal, and low priority) - I

Hi all, I have been getting some strange results with HTB in kernel 2.6.11, and was wondering if anybody could give me some advice. Also, if someone could direct me to the changelog for the recent versions so I can see if it is worth upgrading? Anyway, the problem can best be summed up by looking at the output of ''tc -s -d class show dev eth0''. Some of the relevant results

Hi, I''m using tc and HTB to shape my outgoing ADSL traffic. I was trying to make some graphs on the classes by meassuring the "sent bytes" of each class using rrdtool to store the data (as kbps after conversion). I expected that meassuring the root class I would get values similar that the ones I get measuring the interface counters but they differ by a large amount. Is

What''s going on here? I''m spewing UDP traffic at this thing, and it is exceeding the ceil. Anyone know how to fix this? class htb 1:613 parent 1:5 leaf 613: prio 6 quantum 2560 rate 20480bit ceil 103360bit burst 15Kb/8 mpu 0b overhead 0b cburst 1728b/8 mpu 0b overhead 0b level 0 Sent 16591370 bytes 4159 pkt (dropped 39449, overlimits 0 requeues 0) rate 412384bit 6pps backlog 0b

I have to match my packets based on MAC address, which I cannot do in the POSTROUTING chain, so I do it in PREROUTING using MARK. Then, I match on the MARK in the POSTROUTING chain to do a CLASSIFY. But this does not seem to work: wireless-r1 bwlimit # iptables -L -v -n -t mangle Chain PREROUTING (policy ACCEPT 3353K packets, 941M bytes) pkts bytes target prot opt in out source

Hi Here is something that worked with with 2.6.10-1.771_FC2smp and stopped working when I upgraded to 2.6.16-1.2069_FC4smp. These are fedora kernels and the network controller is an Intel Gbit (e1000) running a 100 Mbps Full Duplex. Don''t know how or if this matters but the 2.6.10 kernel has CONFIG_X86_HZ=1000 and the 2.6.16 has CONFIG_HZ=250 The idea is to just shape to , say 2Mbit, a

Hi, I''m trying to get HTB working correctly on Centos4 (RHEL-based) with kernel 2.6.9-34.EL. I have two gigabit network interfaces bridged together and I have created the following: tc qdisc add dev eth2 root handle 1: htb default 1 r2q 8000 tc class add dev eth2 parent 1: classid 1:1 htb rate 100Mbit burst 24k cburst 24k (I have been trying different parameters). The network is

Hello, I''m using tc to limit the bandwidth of our wireless customers. I have a working script, but I''m not happy with it. I''m trying to write a more sophisticated script, but when I run it, it give me this error: RTNETLINK answers: File exists I have no idea what this error means or how to fix it. Here is a portion of the script (the whole script shapes several

Hello, Thanks for the great Shorewall which has replaced my hard to maintain home-made scripts. First, what works. Our local network is 10.48.X.X with multiple vlan, each on a dedicated interface. We use Shorewall 4.4.11 from Debian Squeeze. We have a 2 ISP: - isp1 : an optical fiber provider with 10 Mbps. - isp2 : a DSL provider with 15Mbits/1Mbits. We use isp2 as the default outgoing

Greetings - I''m new to QoS, so please be gentle (and yes, I''ve RTFM, though I don''t understand every bit of it) Here''s the thing; I''ve tried several scripts--simple and complex--for classifying my Vonage traffic into a high-priority queue, but no matter what I do it doesn''t seem to work. Right now I''m using the HTB script
