BGP is implemented by routing tables maintained by all of the routers on the internet. For users with newer kernels 2.

Your email address will not be published. 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 hoto 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. The danger of congestion on the network can be headed off by specifying the behavior of switches.

However, you probably will never need all of the techniques of LARTC all at the same time all across your networks. PBR involves instructing your routers and switches to use some other method instead of the default Border Gateway Protocol BGP in order to select the adjacent network onto which it should forward data.

If class-based queuing interests you, take a look at this free class-based routing program that is written for Linux. Bert Hubert has offered to continue hosting the old mailing list archives at http: So if you want to ask us a question, subscribe to the larfc mailing listand ask it! A section of examples. 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.


A section detailing the classifiers. Files were last updated at News Mailinglist Download Manpages Dive in!

1. Introduction to Linux Traffic Control

Learn how your comment data is processed. At the switch level, you need to consider Shortest Path Bridging SPBwhich will divert howot onto an alternative path if the obvious route is congested. HTML from Docbook still needs work, though. On private networks, you have the option of specifying exact routes to a destination rather than letting the router work out the best path. The classes are identified by a number, starting with 0 and incrementing sequentially. Please note that due to excessive spam the list has become ‘members only’ – so please subscribe first!

Typeface formatting and display conventions are similar to most printed and electronically distributed technical documentation. In most lart traffic scenarios, you have the time and power to analyze traffic and expand or adapt resources accordingly. This system takes a little while to set up because you need to specify classes and allocate them to different sources. Consider these simpler solutions before you opt for the complex and composite methodologies that create the Linux Advanced Routing and Traffic Control.

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. I assume that the reader may have no prior traffic control experience. Missing content, corrections and feedback. A GIT tree is available. A section covering meters. In some situations, particularly when serving the publicdemand can be unpredictable.

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. If you have any expertise in any of these areas, please pitch in.

The Quick Guide to LARTC plus five alternative methods

The iproute2 utility offers much more sophisticated methods to direct certain traffic over howtoo routes and create dedicated paths to fast-track traffic from specific sources. The internet is made up of independently owned and managed networks. Everybody is invited to contribute to lartc.

Users of the old mailing list are encouraged to move to lartc vger. If you find this strategy too complicated to implement, there are shortcuts that you can take to simplify traffic shaping. The target audience for this HOWTO is the network administrator or savvy home user who desires an introduction to the field of traffic control and an overview of the tools available under Linux for implementing traffic control.

Polish translation is here. All errors and omissions are strictly my fault. You can implement QoS in an Apache web server as well.

However, there are plenty of other routing strategies that you could adopt.
