NetSim Emulator (Available only with Emulator Add on Module)
A network simulator mimics the behavior of networks but cannot connect to real networks.
NetSim Emulator enabled users to connect NetSim simulator to real hardware and interact with
live applications.

A real node, say PCR sends data to the PC running NetSim, say PCN. When ever a packet arrives
at the interface of PCN this packet is “modulated” into a simulation packet and sent from a source
node (user selectable) in the network (user configurable) simulated to a destination node (again
user selectable). Upon receipt of this packet at the destination, the packet is then “de-modulated”
and sent back to a real destination node PCR.
