similar to: how to implement 802.1p QoS on Linux

Hi I''m on my last year and I''m writing my final project about QoS support in Linux 2.4 kernels and, in general, about QoS in Linux OS. My professor asked me about future of QoS in Linux. And I asking you :) What are the difference between QoS subsystem in 2.4 and 2.6 kernels? What are the future plans for evolution of QoS support in Linux. -- Pozdrawiam Marcin

Hello All, I am interested in QoS provided by Linux, when I looked into IP header I came accross ToS field, also while going more into detail about QoS I found that the QoS based on ToS is serviced thru DiffServ which in turn gives more priority to packets with higher value is ToS field, but I am not able to understand when we finally call dev->hard_start_xmit routine of underlying device

Hello, I''ve tried searching for this but I don''t seem to be able to find a way to search past archives in this list. Is there a way to get a per-process qos functionality in linux? At this very moment, I''m using with success a kind of ''workaround'' in my server, which involves creating multiple virtual ethernet interfaces with different IPs and binding

Hi all, I find the whole QOS area quite fascinating and I''m considering starting a small business to try and push QOS solutions in general to small and medium sized businesses. I would of course be happy to push Packeteer and Cisco kit to those who want it, but to be honest the product of choice from a cost and functionality point of view seems to be linux I would appreciate any

Dear lartc''s members I am a new linux user and I was configured a linux router with cbq.init I have installed a VoIP gateway with one voice port (fxs) for a commun telephone and one ethernet port for the LAN navigation and a ethernet port for wan interfaz, i.e., the gateway do NAT. The gateway has a públic IP at the wan interface and a private IP at the Lan interface. I do''nt

The Linux QoS Library (LQL) provides a GPL licensed, GObject based C API to manipulate the network queueing disciplines, classes and classifiers in the Linux kernel. LQL does not use the TC command as a back-end. Instead, LQL communicates with the Linux kernel via Netlink sockets the same way TC does. 0.5.0 2004-08-30 ----- * Initial public release. * I wanted to get 100% API doc coverage and a

Hy, I''ve two question about the QoS on a Linux system. 1) What''s unit it uses for the rate in the differente configuration of the schedulers, IP rate or Ethernet rate ? 2) Is it possible to attach on a interface, a queues with a strict priority scheduler and two or mores with a HTB scheduler ? For example, a queue for the VoIP with a strict priority, 2 queues for Video and

Hi. I did send this to `jaazz@post.cz'', but I suspect the list is a more appropriate/useful place for it. It''s a question about Michal Charvat''s QoS extension to Net-SNMP. When I look at the MIB entries for the QoS handles, I get something like this - enterprises.qos.qosObjectTable.qosObject.qosHandle.0.0 = Gauge32: 0

I would like to implement an architecture to support LLQ and WFQ with Qos linux elements ! Is possible use CBQ (you can set same parameters to control WRR process) or HTB (how can i controll DRR process) structure ? My idea is to classify packets by List flows, tos flows or connections flows (as CBWFQ on CISCO ) I saw also for WRR patch (http://www.zz9.dk/wrr), but I don''t understand

Hi, all I am interested in Linux related QoS, especially PRIO queue discipline (qdisc). I test some experiments about PRIO qdisc. Host A ------ Router A --- Router B --- Host C | 1Gbps | Host B ---------+ +-------- Host D flow 1 : Host A -> Host C (TCP) flow 2 : Host B -> Host D (UDP) priority 1 queue (pfifo, size 1000 packets ) : flow 1 priority 2

I just wanted to drop a success notice to the list. We always hear the failures, and rarely the successes! ;-) After switching from FC1 and freeS/WAN ipsec to the new native linux 2.6 ipsec (ie: setkey-based) my QoS code suddenly started working properly! Previously, with FC1 and freeS/WAN, I found it impossible and rather buggy (kernel panics!) to get QoS to make any difference at all. My

Hi sombody know what is happen with Jim diGriz''s QoS Script Web Page ? www.digriz.org.uk/jdg-qos-script Regards _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

hi i am running Debian/GNU Linux with 2.4.26 kernel and radius server my kernel conf looks like this <*> Packet socket [ ] Packet socket: mmapped IO < > Netlink device emulation [*] Network packet filtering (replaces ipchains) [*] Network packet filtering debugging [ ] Socket Filtering <*> Unix domain sockets [*] TCP/IP networking [*] IP: multicasting [*] IP: advanced

My latency is kind of high and the voice delay is noticeable. The Asterisk server is on a dedicated host outside of the network. I am performing PAT/NAT using a Cisco router. ns1*CLI> sip show peers Name/username Host Dyn Nat ACL Port Status vitel-outbound/rsreese 64.2.142.22 5060 Unmonitored vitel-inbound/rsreese 64.2.142.116

Hi all, I''m a newbbie in this kind of things. I need an example to configure QOS over a WAN for http, telnet and ftp or a web-interface aplication to start working with QOS. (such as webmin with iptables, but for tc). Thanks in advance Alem.

Hello all, Can anyone recommend a good book which thoroughly explains QoS from a Linux perspective? Something with TC examples & the like. I''ve looked at the following: http://www.amazon.com/gp/product/1580533418/qid=1148368189/sr=1-2/ref=sr_1_2/102-2819973-6353768?s=books&v=glance&n=283155 Engineering Internet QoS. Thanks.

Hi, i''m testing QoS MPLS on IP network. I''m confusing about what are features that permit Multi Protocol Label Switching to support QoS on a network. Can you clarify me it? In particular about the integration between MPLS and DiffServe Thanks in advance for the help _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl

Why not try something like Pebble linux from http://www.nycwireless.net/pebble It is a stripped down Debian install that is aimed at running a wireless hotspot but it is just Debian and you can install whatever you want. It fits on a 64MB flash card but if you install almost anything you will want a 128MB one. It does come with iptables and iproute2 tools as I recall. Patrick

Hello, I''ve setuped a QoS bridge under debian. I would like to know If anyone have got some ressources about how setup perfectly VoIP (SIP/RTP) QoS with Asterisk Might be I should use TOS ? Regards

I''m playing with the rather excellent QOS script from Alexander Clouter at http://digriz.org.uk/jdg-qos-script/ So far I am really impressed with it - a very impressive example of the power of linux QOS rules (has pretty much everything in it from the LARTC Howto!) However, the instructions hint that "for QoS to affect locally generated traffic in a non ethernet bridge setup
