The TAG Network Communication Simulator (or TAG ComSim) is a white-label console utility application written in C# provided by Trust Anchor Group (TAG for short). It can be used to simulate network communication traffic in large-scale networks. Features:

• Extensible: It can be extended by external modules to provide support for new features, communication protocols, etc.
• Scriptable: Logic can be provided through use of script.
• Models: Models are defined in XML files, and include support for defining:
  • Actors
  • Probability Distributions
  • Actions
  • Events
  • Statistics
  • Report Output

The terms of this license are subjects of changes in future versions of the TAG ComSim.

You may not use, copy, emulate, clone, rent, lease, sell, modify, decompile, disassemble, otherwise reverse engineer, or transfer the licensed program, or any subset of the licensed program, except as provided for in this agreement. Any such unauthorised use shall result in immediate and automatic termination of this license and may result in criminal and/or civil prosecution.

The source code and libraries provided in this repository (including references to external libraries) is provided open and without charge for the following uses:

• For Personal evaluation. Personal evaluation means evaluating the code, its libraries and underlying technologies, including learning about underlying technologies. Redistribution of artefacts or source code requries attribution to the original source code repository, as well as a license agreement including provisions equivalent to this license agreement.

• For Academic use. This includes research projects, student projects or classroom projects. Redistribution of artefacts or source code requries attribution to the original source code repository, as well as a license agreement including provisions equivalent to this license agreement. Attribution and reference in published articles is encouraged. If access to other technologies based on IEEE P1451.99 is desired, please contact Trust Anchor Group AB.

• For Security analysis. If you perform any security analysis on the code, to see what security aspects the code might have, all we request of you, is that you maintain the information in a confidential manner, inform us of any findings privately, with sufficient anticipation, before publishing your findings, in accordance with ethical hacking guidelines. By informing us at least forty-five (45) days before publication of the findings, you provide us with sufficient time to address any vulnerabilities you have found. Such contributions are much appreciated and will be acknowledged. (Note that informing us about vulnerabilities in public fora, such as issues here on GitHub, counts as publishing, and not private.)

• For Commercial use. Use of the white-label TAG ComSim for commercial use is permitted. Replication and re-publication of source code is permitted with attribution to the original source code repository, as well as a license agreement including provisions equivalent to this license agreement.

The TAG ComSim console application is run from a command-prompt. Command-line arguments are as follows:

Following is a list of simulation examples that introduces different concepts in simple examples. They can also be used as the basis for new simulation models:

You can extend the simulator by providing links to your own .NET Standard assemblies, and reference them from your simulation model. To extend the simulator, create classes that implement the ISimulationNode interface, defined in the TAG.Simulator library. The classes must implement the public a constructor taking a ISimulationNode argument representing its parent node, and a Model parameter, representing the simulation model in which the object is created. To extend the simulator with new types of actors (for instance, new communication protocols), these classes must also implement the IActorNode interface, or derive from the Actor class.

Following is a list of extension modules provided in the repository:

You can extend the script engine using in the simulator, by implementing new functions or custom parsers. See Script reference for more information. Any assembly you reference in your simulation model that contains script extensions, will automatically be used to extend the script engine of the simulator.

The simulator itself provides the following extensions:

Syntax of simulation nodes are defined in XML Schema files. The following table lists XML Schema files defined by the project:
