NetSim Standard
 

Do you wish to accelerate network R&D and reduce your time-to-publish? NetSim Standard is smartly packaged for Network R&D at universities and comes loaded with almost all the features of NetSim Pro.

01

NetSim Standard

NetSim Standard is available as technology libraries from which users can choose and assemble.
It comes with source C code and allows users to
•    Design new protocols and technologies, as well as evaluate changes to existing ones
•    Test and demonstrate designs in realistic scenarios
•    Optimize protocol and application performance
•    Study the effect of real devices and transmit live traffic using NetSim Emulator. Emulator combines the              real and virtual worlds to create scenarios that cannot be achieved in a lab environment.

NetSim Emulator

What is emulation?

  • NetSim Emulator enables users to connect NetSim simulator to real hardware and interact with live applications

  • Users can test the performance of real applications over a virtual network. If you are designing a new network or expanding an existing network then NetSim emulator will enable you to run your live application over an equivalent virtual network and see how the application is performing in real time.


Use Case

  • Scenario of soldiers communicating as a Mobile Adhoc Network (MANET) using UHF/VHF radios created in NetSim emulation server

  • Each soldier is emulated by a virtual machine created inside physical server The MANET scenario in NetSim covers parameters for mobility, RF propagation losses, L3 / MAC / PHY protocol attributes etc.

  • Real-time traffic such as data, voice or video can be sent between the VM’s i.e. from one soldier to another

  • Output metrics such as loss, delay, error, throughput, quality of service etc. can be measured Different “What-if” scenarios can be played

 

How does it work?

  • Create the desired network in the Emulation server using NetSim  GUI

  •  Run your application

  • Run emulation client in the PC’s/VM’s where your live application run

  • Each live PC/VM corresponds to a node in the simulated network. In the simulated network set the device IP addresses per the real PC/VM

  • Measure various parameters such as throughput, delay, loss etc. for your live application using Wireshare

 

What are the benefits?​

  • Can be used to emulate a wide range of technologies

  • Switching, Routing, MANETs, Cognitive Radio networks, 4G-LTE networks, ZigBee networks

  • NetSim Emulator is a cost effective alternative to hardware emulators that have high costs, complicated configuration requirements and limited scale

 

Where can it be used?

  • Military radio networks

  • Radio telemetry for SCADA systems for water utilities.

  • Satellite link analysis

  • Metro rail networks

  • R&D in new protocol design
