hi, i am currently working on a project on "design of diffserv testbed in linux". i am using tc utility of iproute2 for it. The qdisc dsmark used for marking the DS codepoint at the first hop router makes number of classes depending on the indices given in the command. But i am not clear how at the first hop router does scheduling takes place. what i mean is if i have two flows, whose

Hi all, Supposedly my router is itself streaming traffic to clients. Is it possible for it to mark its packets before going through dsmark?? I have gone through the examples in iproute2/examples, i noticed that there''s always an ingress and egress of which these are 2 different dev. Is it possible for before ingress and egress be the same dev?? I tried the script below but

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, There is some extra information in this email! I am working on implementing Diffserv on linux project. I am using suse 8.0 professional kernel 2.4.21. I have the following RPM:iproute2-2.4.7-697.rpm This supports a number of linux qdisc like cbq, htb among many others but it has no support for DSMARK, which I wish to use. Does anyone know of any patch that I could used or any other solution

hi, I''m a beginner with qdiscs and other lartc stuff. After reading the howto and other related documents (i.e. some papers about linux and diffserv), I decided to start with some test. I found some example script to implement simple diffserv using dsmark, but, just after the first command: tc qdisc add dev eth1 handle 1:0 root dsmark indices 64 set_tc_index the system answered:

Hi folks I have created a script file (dsmark+policing.sh attached) to check graphic an text outputs of simutations, against original examples/dsmark+policing coding (see TCNG Reference Manual-pg.90). It uses tcng coding (*.tcsim file attached) and old tc coding (*.tcsim_old file attached) inserted in tcsim files. Observation 1: The graphic outputs from (*.tc included in *.tcsim) and (*.tc_old

Hello! I have some trouble with dsmark qdisc. I''d like to set DSCP value of my outgoing packets and add a rate limit to each one. I learned HTB and dsmark. They work properly, but I can''t combine them like this: tc qdisc add DSMARK handle 1:0 ... tc class modify 1:1 ... tc class modify 2:2 ... ... tc qdsic add parent 1:1 HTB ... tc qdsic add parent 1:2 HTB ... ->

Did anyone ever answer this one?

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

Hi, I want to setup core routers to do both DSCP marking and to get the DSCP and forward packets based on DS field. I don''t want to separate DSCP marking to be done only at the edge routers. I know that dsmark is both used for DSCP marking and for getting the DSCP and forwarding packets according to DSCPs. In my case, since I want to do both of these I need two dsmarks.(?) I am not

I am trying to compare the behaviour of the Linux DiffServ implementation with that of Cisco, in DSCP remarking for traffic policing. As I understand it, the DSCP is marked at the egress interface (parent queue), based on the class that packets are in. I am looking at what happens at an inter-AS boundary. DSCP marked traffic coming into the Edge Router need to be policed and remarked: e.g. EF

Hi stef and all I want measure the policy perfomance for video traffic on mpls diffserv network. there are two different polices for video packet 1. Video packets that are marked that are over the limit are to be rejected at the edge router. 2. Video packets that are marked that are over the limit are to be downgraded as best effort and are sent through. Before video enter my mpls

Hy, I would want to mark the packets that are entering in a machine, with a mark for using diffserv with DSMARK. My machine has 2 interfaces, a ethernet and a wireless. The ethernet interface is eth1 and the other is wifi0. Firs, I would want to test that I would be able to mark the tos of the paquets that I would be receiving, for this I write in the console of my linux: iptables -A

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, I am currently working on a project on implementation of diffserv testbed using tc utility from iproute2 package. i am struck in the dsmark qdisc which allows to mark the DSCP field in IP header at the first hop router. Once the packets are marked at the first hop , how to schedule them at the outgoing interface of the router.What i mean is after creating classes for each DS value, how to set

Hi, I want to use the dsmark, but it always says: "unkown qdisc", although I have enabled it (y in Network options), and I have my kernel recompiled. I am using SuSE 8.1, 2.4.20 Kernel, tc available at the HTB site (with already precompiled HTB queue). Can anybody find the problem? thx _________________________________________________________________ MSN 8 helps eliminate e-mail

I have a Gentoo Linux (kernel 2.6.11) server. Several months ago, I made a traffic shaping setup for my box (running a 2.4 kernel then) that worked beautifully. It gave high priority to SSH and RealAudio traffic, and put HTTP downloading traffic on a lower prio so they could only use what bandwidth was left. However, I''ve only just realized that tc is no longer accepting the commands I
