The Linux kernel has some built-in capabilities for doing bandwidth management.

This HOWTO on Linux Advanced Routing & Traffic Control has a great overview of Queueing Disciplines for Bandwidth Management. See chapter 9 for details - http://www.ds9a.nl/2.4Routing/HOWTO//cvs/2.4routing/output/2.4routing.html

Here is a presentation given at Linux Kongress 2001 on bandwidth management using Class-Based Queueing (CBQ) and Hierarchical Token Bucket (HTB) - http://ds9a.nl/cbq-presentation/

This link has technical information on HTB theory and implementation. HTB is considered to be an easier and more scalable alternative to using CBQ for bandwidth management - http://luxik.cdi.cz/~devik/qos/htb/htbman.htm
