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. How does it work?
(Watch this Video)
Create the desired network in the Emulation server using NetSim GUI
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
Run your application
Measure various parameters such as throughput, delay, loss etc. for your live application using Wireshark Where can it be used?
Military radio networks
Radio telemetry for SCADA systems for water utilities
(Application Note) Satellite link analysis
Metro rail networks
R&D in new protocol design
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 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
