Hi all! In short: Anybody wrote a patch for DSMARK to make it capable of marking only a ratio (a given arg to the tc command) of the packets it gets? Say, 20%? Or, do I have to hack into the source? Alternatives, like a filter spitting packets to 2 different DSMARK based on this ratio? In long: I''m a hungarian univ student involved in a project (RMD-QoS stuff) which needs

Hi all! Anyone got the same problem? If I: tc qdisc add dev eth0 handle 1:0 root dsmark indices 4 set_tc_index it works fine. If I: tc qdisc add dev eth0 handle 1:0 root dsmark indices 4 it says: RTNETLINK answers: Invalid argument I just don''t need that set_tc_index stuff for marking.

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

Hello, What exactly is the use of the "reclassify" option in the policing options of tc filters? According to LARTC: " reclassify Most often comes down to reclassification to Best Effort. This is the default action. " I don''t quite get the meaning of that. It could mean to let other filters handle it, but that is exactly the "continue" option. Could

Hi All, Is there a simple way to convert a string such as c("A", "B" ,"C", "D") to a string of c("Group1", "Group1", "Group2", "Group2"). Naturally I could use the factor function as below but I don't like seeing that warning message (and I don't want to turn off warning messages). Perhaps a function

Hi all, Is the reclassify function useful for really reclassifing ? I couldnt find any samples or documents about this function. I want to pick a packet that''s over a specific rate, and reclassify that to arbitrary class that I specify. I''ve tested with the ingress filter, but it didnt work. (the script below in the ingress, and a simple qdisc, class structure at the egress)

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

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

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

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

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 ... ->

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

I''m trying to configure dsmark qdisc on 2.6.11.4 user mode linux and tc from iproute2-2.6.11-050314. I think I have some mismatch in my setup since adding dsmark qdisc fails *unless* I specify "set_tc_index" argument which I believe should be optional: # tc qdisc add dev eth1 handle 1:0 root dsmark indices 8 RTNETLINK answers: Invalid argument Mar 20 13:00:50 user user.debug

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

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.)

I want to set the DSCP field of the incoming packets. And then put them in the correct queues. I can mark the packets: iptables -A OUTPUT -t mangle -d 10.10.10.12 -j MARK --set-mark 1 tc qdisc add dev eth0 handle 1:0 dsmark indices 64 set_tc_index tc class change dev eth0 classid 1:1 dsmark mask 0x3 value 0xb8 tc filter add dev eth0 parent 1:1 protocol ip prio 1 handle 1 fw

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
