If you don't want a GUI and the fancy what if scenarios, it is not difficult to write a Perl/Script that does constraint-based routing or Multi-commodity flow problems. I would guess 2-3 weeks if one is familiar with basic linear programming.

So the bad thing is the software is very expensive. It's the only software that can simulate Constraint-Based routing now.

I believe that WANDL has a tool that can be used for static TE purposes, but you are on your own for traffic models.

At NANOG the lack of traffic engineering tools came up. Has anyone heard of any packages coming to market. Or looked if tools from other industries could be used as a starting point. Anything from the electric power transmission or road traffic world we could use? Or do IP packets have such different properties (e.g. re-transmission, independent next-hop behavior, etc), its not a good idea to even try.
