OPNET works extremely well in many diverse application regions of communication networks. Some examples of possible applications include local area networks, mobile packet radio sites, ISDN architecture, distributed sensor as well as control networks and tactical sites.

OPNET simulations use four separate modeling domains called Network, Node, Process, and Link illustrates, network models rely on madness of the node models which in turn incorporate process models. In addition, link models are used to characterize links within the network domain. The design methodology for simulation is generally bottom-up in that the consumer first creates process models, then constructs node models which add the processes, and finally constructs network models which are populated with node models
Process models are specified in the proto-c language which relies on a graphical editor to capture the actual structure of the process by means of a finite state machine (FSM). The FSM provides the logic of the process product within its states and transitions. Process models make use of a library of kernel procedures which support access to packets, network variables, statistic variety, packet communication, and other simulation support.
The link domain allows incorporation associated with custom or user-specific link products within OPNET simulation. The communication link between each transceiver couple is modeled as pipeline which provides flexibility in specifying the media between any two nodes. Link models are written directly in C and are also linked into the simulation.
