Greetings all,

Working in concert with the original authors, Klaus Rechert and 
Patrick McHardy, I have translated their article "HFSC Scheduling 
mit Linux" [0] on Hierarchical Fair Service Curve (HFSC) into 
English [1].

   http://linux-ip.net/tc/hfsc.en/

Although the original content is not available directly from their 
website, Linux Magazin published the German article in 2/2005 [2].  
The article is apparently slated for republication in special 
edition 3 of 2006 [3] (I don't know whether it is available yet).

The HFSC queueing discipline itself was written by Patrick McHardy 
and added to the Linux kernel over two years ago, yet there isn't a 
great deal of documentation in English on the implementation itself, 
as he himself observes.

I undertook this effort as a result of a posting on this list [4] 
from several weeks ago, inquiring about further documentation on 
HSFC.  Thanks very much to Klaus Rechert for reviewing the 
translation and Linux Magazin for allowing the English translation 
to be distributed.

The academic work underlying HFSC was submitted as an ACM paper [5] 
in 1997, and is available in English to illustrate the conceptual 
underpinnings of HFSC.

The article announced here is a translation of a practical 
explanation of a typical usage case for the Linux HFSC 
implementation.

I welcome comments and questions,

- -Martin
