Linux Advanced Routing and Traffic Control - This is the main project page for the actual traffic control code found in the linux kernel (2.4 & 2.6). Pre-2.4 kernel required patches, but this group put out such phenomenal code that it is now included as part of the Linux distribution.
- Queuing Disciplines for Bandwidth Management - A subsection of LARTC explaining Queuing Disciplines. A must-read for the serious traffic shaping enthusiast.
- Classful Queuing Disciplines - A subsection of LARTC explaining the Classful Queuing Disciplines, and how packets can / are classified.
Traffic Control Next Generation - TCNG is about moving forward from the current traffic control implementation. Some really excellent free tools can be found here for testing queuing applications.
Linux Bridge + Spanning Tree Protocol HOWTO - While slightly outdated (patches are no longer needed if you use 2.4 or 2.6 kernel) this is a great primer on understanding what bridging is all about.
