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 graphs and tables
Packet animation to visually understand protocol working.
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.

Q. Can our university students work on NetSim from home?


  • Yes. Students can access NetSim their homes via our cloud servers.
  • NetSim cloud is a hosted managed license server provided by us to our customers. There is no need for customers to any longer manage Dongles, MAC IDs, and other issues related to license servers.
  • In NetSim cloud, Tetcos’ manages the set of license server hosts which run the license server processes for our customers. It is a pure license-as-a-service offering, and there is no license server for customers to install.
