Network Simulator Software

QualNet – Network Simulator

QualNet network simulation software enables scientists, engineers, and network planners to quickly and accurately model and test existing or proposed data, voice, and video networks. Combining power and ease of use, QualNet network simulator provides the best platform for success in designing new networks or expanding and upgrading existing networks.

QualNet Network Simulation Software Key Capabilities

  • Scalability to thousands of nodes enables more sophisticated design and analysis
  • Highly efficient processing enables faster-than-real-time simulation optimizing productivity
  • High-fidelity models represent real-world network behavior and deliver more accurate results
  • Cost-effective “lab-based risk reduction” technology provides solutions to mission-critical, business-critical problems
  • Compatible with Windows and Linux on 64-bit multiprocessor architectures
  • Connect OTB, real networks and third-party visualizations to enhance the network model.

QualNet has been recognized as an industry leading network simulation software suite for over 20 years and has become a standard choice within commercial, military, and government organizations.

A Full Suite of Network Simulation Tools

QualNet Architect – Design and Visualize

QualNet network simulation software gives you the freedom to experiment, and the ability to quickly adjust and optimize network topology. Design Mode provides an intuitive visual network simulator interface allowing users to quickly build complex virtual network models. Users of script-based network simulators will appreciate the ease of use, efficiency, and flexibility of the QualNet design environment.

QualNet’s feature-rich network simulator enables you to assess the performance of networking components and configurations under diverse operational conditions. Perform in-depth visualization and analysis of a network scenario created in Design Mode. As simulations are running, users can monitor packets at various layers flow through the network and view dynamic graphs of critical performance metrics.

Virtual network models created by network engineers with the QualNet Developer platform can be leveraged by users of the Run-Time platform for ongoing analysis and experimentation.

QualNet Analyzer

Analyzer allows you to evaluate data from each netsim run to verify that the network is operating as expected or if further optimization is needed. Simulation results can be analyzed to assess network performance, identify potential problems, understand the root cause, and resolve issues prior to deployment. Analyzer’s statistical graphing tool displays hundreds of metrics to provide a deeper understanding of what is happening as data moves through various points of the network.

QualNet Packet Tracer

Learn how data moves through a protocol stack and around your network. You can do so through animated visualizations over your model or XML exports, helping you identify any interruptions.

Large Expandable Library of Network Component Models

Component models are the building blocks for creating virtual networks within the network simulator environment. Just as live computer networks are constructed out of individual pieces of equipment and software, virtual networks are created out of previously defined models of network hardware, protocols, radio waveforms, and other elements that influence network behavior and performance.

QualNet network simulation software includes communication system component libraries for creating network models. A broad range of optional component libraries are available to add more specialized functionality and network protocols.

Network Simulator Benefits – Optimize Performance and Reduce Costs

Network simulators offer an efficient, cost-effective way to assess how the network will behave under different operating conditions using different hardware, software data transmission configurations.

Simulate New Hardware and Configurations

Network simulator software allows testing for a range of requirements and situations, such as:

  • Designing new architecture or operating modes, using pre-configured or user-designed models
  • Simulating response and impact of planned network upgrades
  • Testing new mobile wireless equipment in operationally accurate (ground-based, seaborn, and airborne) environments

Analyze “What-if” Scenarios

Network planners also use network simulator software to conduct “what-if” analysis to determine how changes to network traffic, equipment failure, weather and other external factors may affect the network:

  • How will the latency of my video conferencing application be affected if I add 50 new users to the network?
  • How will the data link be able to support the mission requirements if an airborne asset is lost?

Conduct Network Training and Demonstrations

Network simulators provide an excellent tool for training users on existing networks and for demonstrating proposed network designs to engineers, management and other stakeholders.
