similar to: VQs in Gred!

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 HTB1 (af1) (1MB) GRED(1-3)grio |

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 when i try to add an HTB before the

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= n is given by the sum of the virtual queues with priority greater than n ... I have

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)

Hi, I have made some changes to the file sch_gred.c to modify the GRED queueing discipline to support the following features: 1) The first virtual queue should get absolute priority while dequeueing (not caring if the others get starved) 2) While in equalise mode and with RIO mode enabled, the packets in the first virtual queue should not be counted for calculating the qave. I want to confirm if

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 does not work? Any

Hi i have configured my server with cbq and gred. The problem is that the cbq doesnt drop packets. 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 being generated is more than 5Mbit with the

hi, Is there a way to calculate Gred parameters, given a desired delay (e.g 100ms)? Thanx Ntanzi ____________________________________________________________________________________ Do you Yahoo!? Everyone is raving about the all-new Yahoo! Mail beta. http://new.mail.yahoo.com

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 _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl

Sorry all, this is the missing email that I referred to previously. I inadvertently sent it only to the original poster rather than the list. Sorry for the wasted b/w for those who don''t care...

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 seem ideal as most networks still honor it to varying

Hello, Normally, in addition to such qdisc scheduler mechanisms as FIFO, PQ, WRR, WFQ, are there any more? Then, there is a confusion on scheduler in Linux enviroment: Assume there is a qdisc, such as RED as a leaf qdisc in a router, we know, if there is packet which want to enqueue the packet, the Function red_enqueue is called, but when the packet leave the queue(when the Function red_dequeue

Hello, This is a question about diffserv on linux. We know, there is a file sch_dsmark in linux source code. Now, i want to add something in the function dsmark_enqueue, for example, i want to add a function which can add a class and queue automately in dsmark_enqueue. That is, not using the command tc. After adding one, it works well, but when add the second one, there is a kernel panic:

We''re using tc to classify all packets currently - it avoids conflicting with other packages that want to play with the ipfilters, and up to this point has done everything we need. However now I''d like to map the four htb flows I''ve set up (and are working great on their own) to the four wireless hardware driver queues when the driver currently only has support for

All: I am tasked with creating 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.)

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

Hello all, Please could someone help me with this, I have been trying for days to get this to work. I would like to have BE, AF & EF classes with HTB qdisc. I can''t find any scripts online where this has been done. If I enable this filter: #tc filter add dev eth0 parent 2:0 protocol ip prio 1 \ #tcindex mask 0xf0 shift 4 pass_on then BE & AF classification seems to be fine but

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 - enqueue 2 - drop &
