History [edit]
NetSim is a stochastic discrete event simulator developed by Tetcos, in association with Indian Institute of Science,[1] with the first release in June 2002. Recently, NetSim has also been featured with Computer Networks and Internets V edition by Dr. Douglas Comer, published by Prentice Hall.[2]

Performance Metrics [edit]
NetSim provides network performance metrics at various abstraction level such as Network, sub-network, Node and a detailed packet trace.[5]
Custom Code Development [edit]
NetSim comes with an in-built development environment, which serves as the interface between User’s code and NetSim’s protocol libraries and simulation kernel. Protocol libraries are available as open C code for user modification. De-bugging custom code during simulation is an advanced feature: i.e. a simulation can be started and then at user determined breakpoints in the code, users can perform single-step, step-in, step over etc. This can be carried out at various levels (depending on where the user code links) including at a per-packet interval.[6]
Modeling and Simulation Services [edit]
Using NetSim modeling & simulation services are provided in a variety of networking technologies and protocols including MANET, Wi-Fi, Wi-Max, IP, MPLS, WSN, QoS, VoIP etc. This can help avoid the time consuming process of programming, customization and configuration commercial simulators to meet customer specific needs
Customers [edit]
Over 250 universities worldwide are using NetSim, including IIT Kharagpur, BITS Pilani, NIT Surat, Anna University, Aleppo University, Dar Al Hekma, INTI, Barry University, Szczecin University, and others.[7] Several defense agencies and DRDO labs use NetSim for modeling the unique requirements of defense R & D crucial to Network-centric warfare.
