Re: [PLUG] Fwd: [plug-announce] Tuesday, Dec 13, 2011 - "Journey to the Center of the Linux Kernel: Traffic Control and QoS" presented by Julien Vehent (PLUG North@CoreDial in Blue Bell)


Hi Everyone,

I'm a bit late (writing from the airport) but here is the material for last Tuesday's talk. Thanks a lot for showing up, and I hope you enjoyed it !

The slides are here: http://4u.1nw.eu/Plug-North-QoS-2011.pdf

Some QoS scripts we discussed, as well as a perl code for the graphing with rrdtools live here: https://github.com/jvehent/lnw-tc

The main source is this article: http://wiki.linuxwall.info/doku.php/en:ressources:dossiers:dspam

Maintaining and improving this article is a constant work. I'm hoping to cover HFSC in the near future with the help of the folks from the netdev mailing list. If you stumbled upon typos or think that some of the chapters could be rephrased in a better way, feel free to shoot me a email.

Cheers,
Julien

Hey guys,

Just wanted to add that this time, we might go a little bit more into the
nifty details of DSL links, why they suck and how to fix them.
If you have never heard of powerboost or bufferbloat, or if you wife yells at you because this torrent download is making her netflix freeze, there might be
some interesting stuff in that talk for you.

I'm sure the folks at coredial will have some interesting latency stories to
share as well :)

Julien

  This month, PLUG North welcomes back Julien Vehent, who will be
  giving a presentation entitled "Journey to the Center of the
  Linux Kernel: Traffic Control and QoS".  Julien has previously
  given a version of this talk at PLUG Central.

    We will look into the QoS layer of Linux, talk about processing
    packets and managing queues, read a bit of C (although this is
    not my specialty) and play with TC and IPTABLES to prioritize
    traffic on web, email, bittorrent and whatever you like.  I
    will bring a test machine to do some demos.

  The meeting will take place on Tuesday, December 13, from 7-9pm (7-8
  General Q&A, 8-9 Presentation) at CoreDial:

  CoreDial (http://www.coredial.com/)

    1787 Sentry Parkway West
    Suite 100 (Building 16)
    Blue Bell, PA 19422

  Directions and other information are on our website:

    http://www.phillylinux.org/locations/coredial.html

  We request that you RSVP at rsvp@phillylinux.org if you intend on coming
  so we have some idea of how many to expect, but it is not required.
