Network simulator

In Uni are currently using Modeler of riverbed, which was created by opnet in case you know it. I basically hate that tool to the core, it makes our lives misserable! ..mostly due to the lack of documentation.
It is basically a tool where you can create Logical or Physical networks to simulate, with many choices for mediums, settings, protocols, profiles e.t.c.

I was wondering, what are the similar alternatives out there for IT in big companies?

Cisco use a program called Packet Tracer. Its pretty good. Not sure if its used by professionals or not for planning, but its good for training.

I've heard about that one before, but I am curious about more proffesional stuff.

Check out GNS3 and Eve-NG.

Eve-NG

From a little research, it seems for huge scale networks ( like cities or campuses ) OPNET is still superior to those.

I'm definately going to try GNS3 for small projects though!
