similar to: GRED and HTB

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

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

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 fellow traffic-shapers, I am implementing a Diffserv CORE router using Linux kernel 2.4.18. I used this excellent website (http://www.opalsoft.net/qos/DS-38.htm) using AFHTB as a starting basis for my EGRESS diffserv implementation - and all works great so far!!! But my project has an additional requirement. There are services running locally on the router which are sending/receiving IP

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 |

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)

I am wondering whether the commands ''tc filter change'' and ''tc filter replace'' are working. Googling around revealed a few emails on the LARTC stating that unfoirtunately they do not work. A quick check showed that they are still not implemented (properly). Some propose a solution to build a second tree of filters and apply the 2nd one when a need for it

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

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

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

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->packetsin and q->bytesin. At last the packet was put into the

Hello, I am a newbie . I use a PC which have Windows OS . I want to monitor bandwidth , bytes, packets, packet dropped etc at several linux routers . I want to ask you some questions : Can I use round robin database and mrtg tool to generate html files at linux routers and call them from windows PC ? If it is impossible , can I use snmp to retrieve data from linux router at windows PC (snmp

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

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

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...

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 &

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.)
