discrete event simulators for C++

Question

I am currently looking for a discrete event simulator written for C++. I did not find much on the web written specifically in OO-style; there are some, but outdated. Some others, such as Opnet, Omnet and ns3 are way too complicated for what I need to do. And besides, I need to simulate agent-based algorithms capable of simulating systems of thousands of nodes.

Does anybody know anything suitable for my needs?

Answer 1

We use SIMLIB at my school. It is very fast, easy to understand, object oriented, discrete and continuous simulator. It might look outdated but it is still maintained.

Answer 2

You should consider SystemC, although I'd also recommend taking a second look at OmNet++.
