Traffic engineering tools

[Sean Donelan <sean () donelan com>]

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.
