An alternative to using such devices would be to tune the BGP
configuration of the routers. See below for a description of an
algorithm that allows to determine the optimum configuration of 
BGP routers for some traffic objectives

This work is being pursued in the framework of a governement-funded
three-years research project, where we are developping an open-source
traffic engineering toolbox. This objective of this toolbox is to
provide a set of tools that can be used by ISPs and entreprise networks
to optimize their intradomain and interdomain traffic flow. The first
release of the toolbox is planned for november 2004. To help us fit this
toolbox to the needs of ISP and enterprise networks, we would appreciate
if you could fill our survey at :
