IF you're after some Kernel-related info.., then before, wasting time looking thru the mailing lists, it might be a good idea trying to go here..

The Linux-Kernel Archive

Linux Netdev Mailing List - discusses the development of Linux's networking code, including IPv6 and related topics.

The linux-kernel mailing list FAQ -> huge document!

atm.tut.fi mailing list-archive - contains the following: diffserv, ietf-announce, linux-atm, linux-diffserv, policy, rap, rsvp

Misc

http://www.linuxdoc.org/LDP/nag2/x-087-2-ipmasq.html Linux Iproute2

The Iproute2+tc package allows access to the variety of networking features in the 2.2 kernels such as: Policy routing, NAT, QoS, advanced tunnels, RSVP and DiffServ, etc. NOTE: tc: Linux traffic control

One of the places to get started. -- very detailed. Other site/s:http://defiant.coinet.com/iproute2/ -- not easy to understand

For Iproute2 HOWTO, click here . Mark Lamb has collected some mail list messages that discuss the usage of these tools, here.

Wonderful World of Linux 2.4 -- a LONG article by Joe Pranevich, talking bout the 2.4 kernel

So far, from what I've found out, there's also an online-book which serves as an "Introduction to the Linux 2.4 kernel", here.

http://www.linuxdoc.org/LDP/nag2/x-087-2-ipmasq.html QoS This section describes QoS support on Linux . For more info. on QoS related links, click here|http://www.linuxdoc.org/LDP/nag2/x-087-2-ipmasq.html] . What is available in Linux QoS support?

Prior to 2.4, the kernel had the following:

Each network device has a queue associated with it.
There are 11 types of queuing disciplines currently supported in linux .
Each queue has a scheduler associated with it. Queuing disciplines and classes are tied to one another.
Filters, which are used to classify packets based on certain properties of the packet, e.g., TOS byte in the IP header, IP addresses, port numbers etc.

What Linux 2.4 can do for you? summarised from here

Throttle bandwidth for certain computers
Throttle bandwidth TO certain computers
Help you to fairly share your bandwidth
Protect your network from DoS attacks
Protect the internet from your customers
Multiplex several servers as one, for load balancing or enhanced availability
Restrict access to your computers
Limit access of your users to other hosts
Do routing based on user id (yes!), MAC address, source IP address, port,
type of service, time of day or content

The iproute2+tc package is required for accessing the QoS features of the kernel. #8216tc#8217 (traffic conditioner) is used to set up queues, classes and filters. It uses netlink sockets to interface with the kernel. -- in English - it does the Band-width-division, creating traffic 'classes', blah, blah ....

There are a few QoS-related HOWTOs here.

DiffServ On Linux

From what I understand, 2.2.x series probably does not support DiffServ directly, so it needs patches, available from here. 2.3 kernels already contain all the changes to support Differentiated Services.

My earlier posting about the report made by the University of Kansas on Linux QoS support, the kernel cannot differentiate between Assured Forwarding (AF) and Expedited Forwarding (EF)</u > -- they used a much older kernel version. Hence, for supporting EF and AF forwarding behaviours on a Linux router (old kernels), a tool called Diffspec was developed by the University of Kansas.

Diffspec

Diffspec, can support both EF and AF forwarding behaviours. It is in the form of a daemon diffspec, which runs on a Linux box with enabled QoS features. The code for this tool can be downloaded from here.

From my reading so far, you probably also need the following tools/patches for supporting DiffServ on linux: iproute2, ds-2 patch (both available from here).
