Hello, I am interrested in the monitoring of the qos qdiscs parameters such as size of the queue, enqueues, dequeues, delay in queue, I made a tool to have those results availlable at http://rawsoft.org, but it will probably not work anymore because of the kernel evolutions (the file sch_red.c is patched for the tool to work). I would like to have all the necessary data coming from the kernel

hello, a friend of mine have this configuration: 10 x PC -- router/linux/rh8 -- ADSL Modem -- ISP let''s say that the bandwidth is: 5M and 800K he does dc++ and counter-strike, so let''s say the UP is full, and the ping from the counter server is 300ms, the server cut the connection, and no more game, the player is unhappy. The normal ping is 50ms. so he thinks to put some

I notice one other small problem with my modified version of SFQ. The fact that packets can be dropped at dequeue time is incompatible with the way HTB (and probably CBQ and others modeled on it) keep statistics. When I fill a low rate queue causing packets to expire and be dropped at dequeue I get interesting statistics like this: This is my variant of SFQ qdisc plfq 8016: dev eth1 ... Sent

Hello Lartc''s users, This is my first contact. I''m trying to implement a new queue discipline based on bfifo schedule. I search on internet but there are some problem(s) that I don''t Know how to solve them and that''s why I''m here asking for your help. Well, These were my steps for the implementation: - Put the new qdisc routine

Anyone notices that using sfq qdisc adds latency compared to pfifo? With "sfq perturb 10" ping latency is around 100-120ms, while with "pfifo limit 3" drops to ~10-30ms (qdiscs belong to htb class). I''m missing something or is this expected? { $TC_CLASS parent 1:1 classid 1:20 htb prio 0 rate 900kbit ceil 1000kbit burst 7k $TC_QDISC parent 1:20 handle 200: {pfifo

Any tips on solving the following performance conundrum: Asterisk 1.8.12.2 running on HP DL360 G5 and G7s tcpdump running to capture UDP 5060/SIP signaling to .pcap files All calls are ultimately B2BUA client -> asterisk -> PSTN Media stays on Asterisk at all times AGI script has exit handler that connects and updates an external database upon BYE from either side. I know that if exit

Hi, Fedora 4, 2.6.15.6 What is the maximum count of qdiscs attached to one dev ? It seems, that only 2048 qdiscs can be attached. Is this correct ? If I try to attache more qdiscs, it complains that file already exists and error talking to kernel. How to increase this count ? Thank You vitula _______________________________________________ LARTC mailing list

Hi, there is something I''m not able to understand about HTB statistics. Why the qdisc show show how many packets are overlimits but in the classes there are always 0 packets overlimits or dropped? I try to expain with a simple example. I create a qdisc htb with only a class and then i do a lot of traffic. pc-innocenti:~# tc qdisc add dev eth0 parent root handle 1: htb default 10

tc qdisc del dev eth1 root tc qdisc add dev eth1 root handle 10: prio bands 6 tc qdisc add dev eth1 parent 10:1 handle 20: bfifo tc qdisc add dev eth1 parent 10:2 handle 30: bfifo tc qdisc add dev eth1 parent 10:3 handle 40: bfifo tc qdisc add dev eth1 parent 10:4 handle 50: bfifo tc qdisc add dev eth1 parent 10:5 handle 60: bfifo tc qdisc add dev eth1 parent 10:6 handle 70: bfifo # www traffic

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 attempting to set up a hierarchy of tc qdiscs with filters, but the filters don''t seem to be working correctly.  I''m running iptables 1.3.5 with iproute 2.6.16.20060323 on a Gentoo 2.6.18 kernel.  The system takes all my tc setup, but does not filter packets as I am expecting it to based on my ruleset. My tc qdiscs and classes are added correctly and report as

Hi all, I''ve done a search through the archives but I can''t find a cause/solution to this. I''m running a FC4 box with the stock 2.6.12 kernel and a FC2 box with a stock 2.6.9 kernel. I''m obviously using iproute2 and the patched tc. When I clear down the qdiscs with "tc qdisc del dev <DEV> root" I get the following in response to "tc

Hello.. I have a linux box and I want to make priority on traffic generated by my LAN''s computers.. I don''t have a guaranted bandwidth, so I wanna use sfq... I want to make traffic to port 80 , 443 , 25 & 110 PRIORITY 1 Traffic src or dest 192.168.0.2 to make priority 2 And the rest to put it in proiority 3.. I did the following : tc qdisc add dev eth0 root handle 1:

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello everybody! I am wondering, whether it is possible to have qdiscs and classes as childs of a class or not. take the following example: ~ ,----- ~ | class 1:1 ~ | / \ ~ | / \ ~ | / \ ~ | class 1:10 qdisc 11: ~ | / \ ~ | ...

Hi all, I''m having some problems setting up qdiscs on a bridge.The config looks a little like this: ifconfig ifb0 up # Bring up the IFB for this bridge. tc qdisc add dev eth2 ingress tc qdisc add dev eth3 ingress tc qdisc add dev ifb0 root handle 1:0 cbq bandwidth 100Mbit avpkt 1000 cell 8 # Raw qdiscs on each bridge port tc qdisc add dev eth2 root handle 1:0 cbq bandwidth

Hello, The qdisc spy has evolved, the new version can spy on udp and tcp connections, the results are displayed upon command. There is no gui for this tool yet, but I will try to make one. If you want to try: http://rawsoft.org Vincent Perrier

Hi all ! I''m building a network appliance whose goals are to enhance Voip quality on 512/128k DSL links. But, i have a voice quality problem, and i think i''m doing something wrong, but i can''t find what. Please excuse my terrible english, i''m french. >From what i''ve read, tc is the tool i need. I read the documentations, readmes and lartc.org

This is an update to iproute2 utilities including bug fixes and features related to 2.6.22 kernel. This package tries to be source compatible across releases. The same source should build on older systems, but obviously the newer kernel features won''t be available. It can be downloaded from: http://developer.osdl.org/dev/iproute2/download/iproute2-2.6.22-070710.tar.gz Repository:

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
