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 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

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, 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 everybody, I try to work with TC for a little while in my study and there still are a few questions that I can\''t find any answer anywhere. Firts about qdisc and classes: - What is exactly the difference between qdsic and class ? They are so \"intimately tied together\" that i\''m not sure not make the difference. Why can\''t we have a qdsic HTB with

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

Did anyone ever answer this one?

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.

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 all! I''m trying to do proportional marking of real-time traffic to indicate link congestion, and for that, I wish to use the DSMARK filter to mark from, say EF to 0xcc. (an unused DSCP value) By proportional, I mean, if congestion on the egress link is, say 38%, then I shall remark 38 packets of every 100 leaving eth0. I already wrote some scripts, and I can measure the overload

I want to set the DSCP at the ingress of the router. I tried the following: iptables -A OUTPUT -t mangle -d 10.10.10.12 -j MARK --set-mark 1 tc qdisc add dev eth0 handle ffff:0 ingress dsmark indices 64 set_tc_index tc class change dev eth0 classid ffff:1 dsmark mask 0x3 value 0xb8 tc filter add dev eth0 parent ffff:1 protocol ip prio 1 handle 1 fw classid ffff:1 But the DSCP

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, 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 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, 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:

Hello! In our experiment, we are trying to mark IP packets at a source host. Some of these packets have a 28-byte "IP Options" field, hence a 48-byte IP header. We observed (using ethereal) that the tc script at the source appropriately marks the packets that DO NOT have an "IP Options" field (i.e., regular 20 byte header), however, all the packets with the "IP

Hi guys, Does anyone know of a RPM for suse 8.0 kernel 2.4.21 that contains dsmark or alternatively a patch that I could use with the RPM I have already. Thanks in advance n --------------------------------- ALL-NEW Yahoo! Messenger - all new features - even more fun!
