RE: Traffic engineering tools

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.

After the investigation, currently only WANDL in the market can do/support
the

MPLS+ATM or IP simulation. So the bad thing is the software is very
expensive.

It's the only software that can simulate Constraint-Based routing now.
