similar to: bandwith limiting and prio classes

Hello mailing list, i stand bevor a mystery and cannot explain it J. I want to do shaping and prioritization and I have done these following configurations and simulations. I can´t explain, that the combination of PRIO and TBF is much better than the HTB (with the prio parameter) alone or in combination with the SFQ. Here are my example configurations: 2 Traffic Classes http (80 = 0x50) and

Hi, I am working on linux 2.6.16.I tried to prioritize traffic using prio module but its not working well.It always maps to same class irrespective of ToS.Is it possible to fix it using filters?Anybody fixed this problem? -- Regards Archana Rajagopal _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc

Hi, i''ve following problem. One of our gateway router, which connects some of our customers should have bandwith limit. So customer A with IP XX should have 2 Mbit, customer B with IP YY should have 10 Mbit. There is no need of borrowing bandwith so no fairness needed. My simple question: with which technique should I manage this shaping? Or is there any existing project which

I have a doubt. If you use such a script monitoring the link status with ping and then reconfiguring, why do you need the DGD patch? You need to do some reconfiguration (change multipath to a single default route) anyway if you use the script, right? Also, the DGD patch uses src to lookup the routing table entry, but if you have a dynamic IP for the WAN interface (PPPoE, DHCP etc), this approach

hi to all, I''m studying traffic shaping using kernel 2.6.8 (debian sarge). well, I have this problem: priority doesn''t work. I try with: - qdisc prio: tc qdisc add dev eth1 root handle 12: prio bands 3 tc qdisc add dev eth1 parent 12:1 handle 13: tbf rate 10Mbit buffer 1600 limit 3000

I thought I had this all worked out, but it seems not. The following tc configuration: tc qdisc del dev ppp0 root 2> /dev/null > /dev/null tc qdisc add dev ppp0 root handle 1: tbf rate 120kbit burst 1200 limit 1 tc qdisc add dev ppp0 parent 1:1 handle 2: prio bands 3 tc qdisc add dev ppp0 parent 2:1 handle 10: sfq perturb 20 tc qdisc add dev ppp0 parent 2:2 handle 20: sfq perturb 20 tc

This problem is driving nuts, so I am seeking help here. Your help will be deeply appreciated. I have made myself a Linux bridge with eth1 and eth0 to form br0. Then I run a script to configure tc with htb on it. But I can never match non-icmp traffic ( such as tcp and udp ) with TOS or DSCP values such as 0x68. The full story as follows :- 1. On the source testing machine, I do this to set

Hi all, I''ve not been able to find an explanation of the relationship between prio and rate as they apply to the HTB technique. Hopefully someone on here will be able to help me. As I understand things, when prio values are assigned to an HTB setup, classes with a given prio value will only be serviced when there are no packets waiting in classes with a lower prio value. Now, does

Hello everyone, First of all, sorry for my poor english. I''ve been working with this for a few weeks and I''m getting sick... I''m trying to control the bandwith in my network using the following script. The machine where the script is running makes NAT, eth0 is connected to the router and eth1 is connected to the Lan. When I run the script it doesn''t appear any

EHLO tc gurus. New to traffic control. Unfortunately, the politicians here in Denmark have decided that a PC is the same as a television set - so anyone owning a PC and internet connection of over 255 kbit/s must pay DKR 2200/year = EUR 300 = USD 400 in television licence fees :-( This is a lot of money for poor students, so we want to offer the students the *option* of limiting their

I run a small Linux webserver and NAT router from my cable modem at home. Whenever someone starts an http download, all other traffic from my LAN is starved. Bandwidth is not really an issue, but latency is particularly horrible -- pings that usually come back in 20ms can take up to 600ms while the web server is active! I set up QoS (netfilter+iproute2) on the NAT machine in an attempt to give

dear All, I'm a new student and my job is too shapping bandwith for our campus faculty network. I want to implement htb with Redhat-9.0 distro. does this distro kernel support htb and tc good ? or i should apply some patch or upgrade kernel ? regards reza

Hi all, Can you tell me where is the documentation for the new IFB (implemented in kernels > 2.6.16). Thanks in advance! Nikolay

The manual says (about prio): > Because it doesn''t actually shape, the same warning as for SFQ holds: > either use it only if your physical link is really full or wrap it > inside a classful qdisc that does shape. The latter holds for almost all > cable modems and DSL devices. I want to wrap prio inside of tbf. Here''s why: I have a server on a DSL line, which has

hi i tried the example given on the examples page to duplicate selected traffic like tc qdisc add dev eth0 root handle 1: prio tc qdisc add dev eth0 parent 1:3 handle 3: netem duplicate 40% tc filter add dev eth0 protocol ip parent 1:0 prio 3 u32 match ip dst 11.0.2.2 flowid 1:3 when i ping from 11.0.2.2 to this interface my machine hangs. the same thing works for drop or delay. i would

Hi, I''ve read the lartc doc but got stuck :) I''ve created a prio qdisc (the example) tc qdisc add dev eth0 root handle 1: prio tc qdisc add dev eth0 parent 1:1 handle 10: sfq tc qdisc add dev eth0 parent 1:2 handle 20: tbf rate 20kbit buffer 1600 limit 3000 tc qdisc add devl eth0 parent 1:3 handlle 30: sfq Then I tried to create filters to make priority traffic go to the

Hello everybody, sorry for bothering you, but after some hours, I''m stuck. I''m living in a student''s foundation where I want to connect lots of people to a tiny DSL link. We have exactly four types of traffic. We want a really hard PRIO solution (as I promised to someone that group X will only use the link capacity which isn''t used by group Y). I could make a

Hello All, I am trying to setup a linux box as a forwarding router based of src IP. The problem is that it does forward the pkts to the intended server specified in the ip rule, but it also forwards it to the original dst (dst specified in the pkt). Here is the setup: [10.1.0.166] [192.168.1.225] |

Hi all, First, let me say I''ve been most impressed with how quickly and professionally people on this list ask and answer questions. Next, let me say that with which I need help is properly configuring strict PQ, and gathering certain stats. Specifically: - I need to create a priority queue with four queues (let''s say they are of high, medium, normal, and low priority) - I

Hello all, My company is sharing it''s internet access with a neighbor and the neighbor in question was eating our bandwidth (both in upload and download) most of the time. I finally set up a linux router to limit the incoming/outgoing bandwidth to his network by adding a tbf on eth0 interface and eth1 interface of the router (neighbor is behind eth1 and we are in-between him and the
