NetSim Network EmulatorNetSim Network Emulator enables users to connect NetSim simulator to real hardware running live applications ( Video, Voice, File Transfer, Email, etc.). This is also termed as System-in-the-Loop (SITL). With NetSim emulator physical hardware and a simulation can interact as a unified system.
As shown in the figure above the configuration is real-sim-real with simulation sync’ed to wall clock. The simulation is used as a transit network in which datagrams experience simulated network effects.
NetSim Network Emulator can be used for various purposes:
- Testing application performance subject to network effects such as error, delay, loss, etc.
- Impact is immediately apparent with no need to interpret from simulation statistics
- R & D in new protocol design. Test your protocol performance with real applications.
- Design state testing before the real devices/software are ready
- Integration into cyber test beds
NetSim Network Emulator is a cost-effective alternative to hardware emulators that have high costs, complicated configuration requirements and limited scale
Example use case for Military Radios
- Scenario of soldiers communicating as a Mobile Ad-hoc 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
Example use case for 5G Networks
- A typical 5G network. Cameras uploading video and phones (UEs) uploading and downloading files.
- Change network parameters such as bandwidth, pathloss, transmit power, antenna count, mobility etc.
- Run various what-if scenarios by modifying the file transfer and video rates
- Study application performance and analyze metrics such as loss, delay, error, throughput, quality of service etc.
