Qualnet Network simulator

Qualnet Network simulator is also used for large, and heterogeneous networks. Distributed applications execute on these networks. A commercial version of GloMoSim is named as Qualnet.

Features of Qualnet Network simulator:

  • Robust for both wired, wireless networks and hybrid network.
  • Useful for simulating diverse types of networks.
  • Optimized for speed.
  • Optimized for scalability.
  • Designed from ground-up as a parallel simulator.
  • Qualnet executes simulation multiples faster.
  • A robust graphical user interface.
  • Used to simulate high-fidelity models of wireless networks.
  • Portability.
  • Model Fidelity.
  • Extensibility.

Platform Support:

  • QualNet executes on all commonly used platforms.
  • Windows NT/2000/XP/ Professional.
  • Solaris.
  • Linux.
  • most UNIX variants.
  • MacOS.

Components of QUALNET:

  • QualNet Architect.
  • QualNet Analyzer.
  • QualNet Packet Tracer.
  • QualNet File Editor.
  • QualNet Command Line Interface.

QualNet enables users to:

  • Optimize new and existing models.
  • Design new protocol models.
  • Design large wired and wireless networks using pre-configured or user-designed models.
  • Analyze the performance of networks and perform what-if analysis to optimize.

Qualnet Libraries:

The QualNet has three libraries of component models which include:

  • Developer.
  • Wireless.
  • Multimedia and Enterprise.
There are two versions of the platform:
  • QualNet Developer.
  • QualNet Run-Time.
