NetSim Academic: NetWork Lab on your Desktop

NetSim Academic

NetSim Academic is an economical option for educational customers intending to use NetSim for lab experimentation and teaching. Looking at doing Network R & D? then NetSim Standard is the product you should explore. The version comparison table shows the features available in the different versions of NetSim.

6 Reasons Why You Need NetSim Academic

If you're a professor looking to set-up / enhance your university's communication-network lab, and unable to manage with legacy software / open source simulators, this is just for you.

NetSim powered lab Possible current lab set-up
1. Easy to use GUI for network design.
Results dashboard with Plots, Tables, Logs, Traces. 		Open source simulators use a command line interface and scripting languages. Very difficult for unskilled users to use and understand
2. NetSim academic versions supports a Wide Range of Technologies including the latest in 802.11, 802.15.4, LTE, IoT, MANETs, 802.22, Enhanced TCP etc No experiments in the latest technologies
3. Painless change as equivalent lab experiments are available in NetSim Using legacy software like OPNET and unable to get upgrades / support
4. Well designed and up to date Experiment & User manuals Unclear documentation i.e written for developers and not students, and lacks screen shots, examples etc
5. Straightforward install and licensing Complex installation process prone to errors
6. Dedicated support - live online support during installation. Helpdesk based support post installation. Training sessions via team viewer. Monthly webinars Open source support - dependent on an informal network of people to respond to your queries on the forum.
