An Accurate, Scalable, Communication Effects Servers for the FCS System of Sytems Simulation Environment

Future Combat Systems (FCS) develops Communications Effects Server (CES) to accurately and dynamically simulate the impact of communication effects on their systems
QualNet Network Simulator used to evaluate the performance of the CES


The ultimate objective of the FCS CES is to support real-time simulation of wireless networks with very large numbers of communicating devices at a sufficiently high level of accuracy that the simulation can interoperate with both physical test articles and human participants

See the whitepaper to learn the key design attributes of why QualNet was chosen:

  • Modular interfaces among protocol stack layers to support detailed, accurate models throughout the protocol stack, including the physical layer.
  • Transparent parallel execution of network simulation models on diverse parallel architecture, including shared-memory multiprocessors, distributed memory multi-computers, and cluster computers.
  • Well-defined external interfaces to support inter-operability (via DIS, HLA, or socket connections) with other software

Key Features of QualNet


Faster speed enables model developers and network designers to run multiple "what-if" analyses.


Our QualNet network simulation tool can model large networks with high fidelity.

Model Fidelity

Our network simulation tool uses highly detailed implementation of protocol models.


QualNet and its library of models run on a vast array of platforms.


Connect to other hardware and software applications to greatly enhance the value of the network model.
