NetSim Standard

Network R&D for universities

Build, simulate, and analyze networks faster than script-based and open-source tools. Every protocol ships with C source code you can modify and extend.

Universities need tools that accelerate research, not slow it down. NetSim Standard is a structured, validated platform for rapid experimentation: design networks in a GUI, extend them in C source, and analyze results without writing parsing scripts.

NetSim vs script-based simulators

The same study, without the scripting overhead of open-source tools.

Task NetSim Standard Open-source simulators
Scenario design Drag-and-drop GUI: place devices, draw links, and assign applications in minutes. Write hundreds of lines of script for every scenario.
Results analysis Integrated dashboard with sortable tables and exportable graphs, no post-processing. Manually parse multi-megabyte trace files.
Visualization Built-in packet animator and plots, directly from the results window. Write external programs for animation and graphs.
Custom code Protocol C source and documentation, ready to extend. Read thousands of lines of C just to understand it.
Debugging Online debugging: attach and watch every variable in Visual Studio. Rely on scattered printf statements.
Interfacing Inbuilt interfaces to Python, MATLAB, SUMO, and Wireshark. Spend days building custom links to external tools.

From design to insight

How a study flows, end to end, in one environment.

1

Design

Place nodes, links, and applications visually. Auto-place or import coordinates from file.

2

Configure

Tune the full stack, APP to PHY, with clear per-device protocol settings.

3

Simulate

Run interactively, or batch via CLI for parameter sweeps with repeatable seeds.

4

Analyze

Read end-to-end KPIs, throughput, delay, jitter, and delivery ratio, in the dashboard.

5

Visualize

Trace flows with the packet animator and plot metrics over time.

Developing algorithms in NetSim is 10 times faster than developing in open-source tools. Trying different scenarios, filtering and plotting output data, batch running simulations, and interfacing with external tools are all integrated, robust, and commercially validated.

What your research gains

From first scenario to a result you can defend in review.

Speed

Accelerate research

Build on validated models, integrated analysis, and C source, so your time goes to your contribution, not the tooling.

Rigor

Reproducible experiments

Profiles, seeds, and scenario variants make runs repeatable for papers and peer review.

Confidence

Publish with confidence

Commercially validated models and clear, exportable results you can stand behind.
