Hi, I am tring to setup AF on my router using GRED/HTB. I plan to mark and set the DSCP with iptables and the ingress qdisc to set the tc_index for the proper GRED vq(1-12). My question is: Is there a way to allow for priority between the af classes and within the af classes? also would it be possible to to the following: HTB(6Mb) | GRED(1)grio...

Hi, I am trying to get assured forwarding/expedited forwarding with gred and htb working. Below is the script I am using. The following steps are what I thing is how the script works. My problem is that if I remove the HTB qdisc from the script and have the GREDS parent as the dsmark it works, but when I add the htb as a parent of GRED and DSmark the parent of htb it do...

Hi, just wondering if this type of configuration would be possible for using AF and EF classes. HTB (6.0M) --GRED 5 (AF1) --HTB(1M) [is it possible to have this with a 1M rate and a 6M ceiling?] --GRED [3 greds using grio] VQ1 -3 --GRED 4 (AF2) --HTB(1M) --GRED VQ1 -3 --GRED 3 (AF3) --HTB(1M) --GRED...

I ''ve been trynig for a long time now to make HTB and GRED to work togethen. The problem beeing that GRED doesn''t use handles (instead it uses DP:1 DP:2 etc) i can not preperly filter traffic to them. Tomas Graf suggested to use the tc_index index of u32 classifier so dear Sant .. i am currently with the following scripts that works! But whe...

I''m successfully using HTB + GRED to shape traffic based on the DSCP field. I would like to strip the DSCP and possibly replace it with normal ToS bits on egress traffic leaving my network. Leaving DSCP set is pointless, and could potentially cause problems with some ISPs that use DSCP internally I suppose. Setting ToS bits would s...

The cbq is configured at a rate of 500Kbit "qdisc cbq 4: rate 500000bit (bounded,isolated) prio no-transmit Sent 100103048 bytes 73933 pkts (dropped 0, overlimits 0) borrowed 0 overactions 0 avgidle 24000 undertime 0 " The traffic that...

Hello, We know, VQs are used in Gred to offer different schedulers, in order to make clear what the VQs are, I have read the sch_gred.c in net/sched/. In the function gred_enqueue(), at first it will find the VQ(q) according to the lower four bits of the skb->tc_index, then some parameters of the q is modified, such as q->pack...

I have managed to dynamically parse the output of commands: tc qdisc ls dev eth0 and tc -s class show dev eth0 Save statistics in an rrd database and display it via a php script. see http://143.233.4.215/graph.php and dload scripts from http://143.233.4.210/qos/ My next step in developing this monitoring software is to somehow manage to create a tree out of tc and then use it to greatly

Hi, In the GRED queueing discipline of linux traffic control, we can define around 16 Virtual Queues with different RED parameters for each one of these. As far as I think, while applying RED on each of the virtual queues, with the grio option set, quave(the average queue length) of a virtual queue with priority=...

Has anyone ever managed to use GRED and HTB ? Been googling all over the net for hours and did not manage to find any proper implementation. In my case all AF traffic goes into VQ 3 In opalsoft afhtb example traffic goes into VQ 1 & 2 any script will do just fine for me Thanks in advance , Antonio __________________________...

...an environment in which DiffServ and IP precedence is handled as close to RFC specification as possible. I have a few problems with implementing this based on current queueing structure. Here are a few of my questions. 1.) Is there any way to get DiffServ AF drop levels without using DSMARK and GRED? Ex. AF11 Gred DP 1 AF12 Gred DP 2 AF13 Gred DP 3 2.) Can I get traffic into GRED DP levels without using DSMARK? 3.) It appears that DSMARK was designed to be the root queuing discipline of an interface. Is this true? 4.) If you filter with DSMARK into a class the TOS value is copi...

Hi all, Can anyone show me pointers on how to get this implemented on a Linux box with tc rules? I also want to know, just how efficient is this Algorithm. AFAIK, inbound traffic control can''t really be achieved without losing bandwidth. In some of the howtos'' I''ve read, one guy had to limit his downspeed to 1/2 his bandwidth to actually control it. And he was saying

Each step lasts for 60 sec. My config script is attached. Thanks.

Good morning i want to enable some debug messages concering htb and gred. The reason is that i want to see the journey of the ip packet through the 2.6 kernel from the start to finish (ethernet interface up to htb and gred classification). In the sch_htc.c i have found the following /* debugging support; S is subsystem, these are defined: 0 - netlink messages 1 -...
