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. Qualnet network simulator is the best choice for research scholars to create virtual models of voice, data and video network too quickly and accurately model behaviour of real communication.

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.
• Qual-Net Analyzer.
• QualNet Packet Tracer.
• Qual-Net 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.

   Above mentioned three libraries are used in QualNet simulator projects to quickly and accurately model behaviour of real communication in a real world scenario.

There are two versions of the platform

• QualNet Developer.
• QualNet Run-Time.
