A section detailing the classifiers. So if you want to ask us a question, subscribe to the new mailing listand ask it!

A Korean translation can be found on here. I may not supply examples in both the tcng language and the tc command line, so the wise user will have some familiarity with both. Although I have made every effort to verify the factual correctness of the content presented herein, I cannot accept any responsibility for actions taken under the influence of this documentation.

Linux Advanced Routing & Traffic Control

If you find this strategy too complicated to implement, there are shortcuts that you can take to simplify traffic shaping. Jobs Bazaar Sponsor Massive thanks to: Please note that the old mailing list and old HOWTO submission e-mail addresses are no longer active. Everybody is invited to contribute to lartc. So, you can run your digital telephone service over your data network, keeping both types of traffic distinct.

An archive of the old mailing list is also available, and google has picked it up as well. The receiving router then makes its own decision on where the next hop will be.

QoS howfo really a form of class-based routing. The iproute2 utility offers much more sophisticated methods to direct certain traffic over specific routes and hoto dedicated paths to fast-track traffic from specific sources. It is more likely that on some switches you need load sharing and on others, you need queue manipulation. Polish translation is here. Bert Hubert has transferred ownership of the domain to Carl-Daniel Hailfinger. The tcng software package defines an entire language for describing traffic control structures.


I strongly recommend to the eager reader making a first foray into the discipline of traffic control, to become only casually familiar with the tc command line utility, before concentrating on tcng. You can implement QoS in an Apache web server hwto well. For users with newer kernels 2. In particular, the following items will be added at some point to this documentation.

You can also restrict the throughput of certain types of traffic and prioritize others through policy-based routing.

If you search for the internet, you will see the term applied to the operations of wifi routers. Target audience and assumptions about the reader. Introduction to Linux Traffic Control. QoS is particularly useful for creating virtual networks.

The controller of each network is its router. BGP is the default method used by network equipment. This information also gets passed on to all of the other routers that connect to the neighbors of the faulty router, propagating routing table updates all over the world.

The classes are identified by a number, starting with 0 and incrementing sequentially. Typeface formatting and display conventions are similar to most printed and electronically distributed technical documentation. Consider these simpler solutions before you opt for the complex and composite methodologies that create the Linux Advanced Routing and Traffic Control. Linux offers a very rich set of tools for managing and manipulating the transmission of packets. Files were last updated at When you make a connection to a web server on the other side of the world, your router does not specify how that packet will get there.


However, you can choose to implement the methodology your own way because the important element is that there are classes — the allocation factor is not imposed by a universal rule. In some situations, particularly when serving the publicdemand can be unpredictable. A section discussing the techniques for measuring traffic.

Broadly speaking, this HOWTO was written with a sophisticated user in mind, perhaps one who has already had experience with traffic control under Linux. You define types of traffic to prioritize and then that priority traffic gets marked with a QoS tag on its way out onto the network. This system takes a little while to set up because you need to specify classes and allocate them to different sources.

So, this technique is just another way to prioritize traffic using the class-based concept. In most network traffic scenarios, you have the time and power to analyze traffic and expand or adapt resources accordingly. Users of the old mailing list are encouraged to move to lartc vger.

So, data units marked with the 0 band will get passed through before any datagram in the queue that is marked with a 1. Please note that due to excessive spam the list has become ‘members only’ – so please subscribe first!
