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

Hi I''m using wondershaper like script. But noticed imperfect scheduling. By googling, I found some patches that takes the aal5 atm overhead in the scheduling algorithms. http://www.adsl-optimizer.dk/ADSL-optimizer/ Before trying it, has anyone tried these patches? they apply on 2.4.29 kernel and 2.6.9 TC. I use centos4 with a 2.6 kernel, so I can''t try these easily. Thanks

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

Hello to everybody, We want integrate in a router/firewall (Debian Based, 2.6 Kernel), an HTB shaper. The goal is to divide the traffic for classes of workstations, at example in three classes, let say A, B and C. Example: A 70 Mb/s B 20 Mb/s C 10 Mb/s If B don''t make traffic, 7/8 of 20Mb/s must be assigned to A and all the rest at B We have used CBQ and HTB, with poor succes. Anybody

Hello good day to all ... this is my setup 1 Linux Wireless Access Point, connected are 4 wireless gateway in which i needed to apply shaping ... ok here is the weird part... clients on each gateway download files from the Acess Point ... a 500 mb file through ftp on gateway 1 which is up to 64 kbps ... the result is from 60-64 kbps speed which is fine ... on gateway 2 which is 128 kbps ... the

Dear list: I have a problem I cannot handle yet, and need to solve it as soon as possible. Would be very greatful with anybody who can help me. I have a 512/512 link to internet, that I want to share between several computers. I have eth0, with a public IP address, conected to Internet, and also, eth1, with a private IP address, for network with the surfing computers. I have a main class with

Hi, One of my customer needs per flow rate control, so I write one. The code I post here is not finished, but it seems to work as expected. The kernel patch is agains kernel 2.6.11, the iproute2 patch is against iproute2-2.6.11-050314. I write the code in a hurry to meet deadline. There are many other things to do ahead for me. The code is written in 2 days (including read other

How can i redirect all traffic that not come from port 80 to a flow ? i was thing about some like tc filter add dev imq1 parent 1: protocol ip prio 7 u32 match ip sport !80 ...... But this not work. Another doubt, if i have two rules that intersects , for example , one filter with u32 match ip src 10.10.10.10 flowid 1:10 and other with u32 match sport 80 0xffff flowid 1:11 , which one will

Hi. I wrote in a reply to a mail on here recently that you can''t set mpu (minimum packet unit) on HTB as you can on CBQ. I''ve just noticed that there is a patch on devik''s site which does mpu and overhead. http://luxik.cdi.cz/~devik/qos/htb/ For dsl users mpu is, for practical purposes going to be 106 - overhead is still variable though, depending on packet size.

Hello List, I''m new to QoS/tcng/HTB and friends, so please forgive me if my question might be silly... After having read lots of HowTo documents I''m totally confused... The Challenge: ============== I''ll have to deploy several "mirror" download servers (Linux) which must be able to handle a huge number of HTTP download requests (about 10k to 20k unicast

Hi everyone. I''m new to this list and I have some questions regarding HTB class. I was trying to see how tc sets the parameters for HTB, but really couldnt understand them. So, I thought that I might ask the wizards. It''s mainly from the source code. 1. What is the cell_log ? (its everywhere in the code) 2. Why does htb calculate its burst(buffer) with tc_xmit_time() ? Is

Hi folks. I started to play with tc+htb last week, and I must confess that this thing is really driving me nuts. All we want to do is control bw, with no borrowing. In order to get the feeling on this subject, I have setup the following test bed. ---A---B---C--- On B: eth0 connecting A and eth1 connecting C. The script. tc qdisc del dev eth0 root tc qdisc add dev eth0 root handle 1: htb

Hello, I''ve just compiled the kernel 2.6.17 and noticed an odd HTB behaviour. For instance: tc class add dev eth0 parent 1:1 classid 1:30 htb rate 1kbit ceil 750Kbit burst 15k tc filter add dev eth0 parent 1:0 protocol ip prio 15 u32 match ip dst 192.168.5.1 classid 1:30 The filter works ok and the traffic to 192.168.5.1 flows through the class 1:30, but the rate gets much higher than

I know there is that handy patch available to very efficiently use ATM bandwidth, but I was wondering what the best values to use with a non-patched iproute2 would be. Anyone here care to check my logic in coming up with these numbers and perhaps suggest better values? My transmit speed is 768kbps per ADSL line (I have two). This is the HTB shaping I do on the interface (logic used for this

Hi, I am trying to use htb to limit bandwidth on loopback for traffic through particular port. Here is the script I am using. tc qdisc add dev lo root handle 1: htb tc class add dev lo parent 1: classid 1:1 htb rate 100kbit ceil 100kbit tc class add dev lo parent 1:1 classid 1:10 htb rate 50kbit ceil 50kbit tc class add dev lo parent 1:1 classid 1:11 htb rate 50kbit ceil 50kbit tc filter add

Im using a Linux machine with standard pc hardware with 3 seperate PCI network interfaces to operate as a DiffServ core router using Linux traffic control. The machine is a P4 2.8ghz, 512mb RAM running fedora core 3 with the 2.6.12.3 kernel. All links and network interfaces are full duplex fast ethernet. IP forwarding is enabled in the kernel. All hosts on the network have their time sychronised

Hello, I have a serious problem with HTB which I wasn''t able to solve myself. I run a masquerading router with ppp0 as interface to the Internet. Three clients need to share a downstream of 1 MBit, which I want to divide with tc. When I see a packet being forwarded to one of these clients, I give it the appropriate unique mark: iptables -t mangle -A FORWARD -d 192.168.34.141 -j MARK

Hello everyone, We are working on HTB with TC and would like some clarifications from your part. Our example is as follows. We have one HTB root class and two HTB classes attached to it, as in this figure : 1: HTB | | |

Hi, I am new to tc and have been reading quite a bit on how to set it up etc. Everything seems to be working fine, until I started scp-ing a large file over a low bandwidth connection as part of my testing process. Here is the setup: my pc --- bridge running tc/htb --- rest of network TC is filtering traffic from "my pc" and classifies it as 120kbit (see my script below). I then scp a
