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]
Model libraries in NetSim[edit]
Modeling and simulation are supported for the below mentioned technologies. Protocol libraries are available with C source code
- Aloha, Slotted Aloha
- Token Ring, Token Bus
- Ethernet CSMA / CD, Fast and Gigabit Ethernet
- WLAN - IEEE 802.11 a/ b / g / n / ac and e[3]
- X.25, Frame Relay
- TCP, UDP
- IPv4 and IPv6[4]
- Routing - RIP, OSPF, BGP
- MPLS
- Wi-Max
- MANET
- GSM
- CDMA
- Wireless Sensor Network
- Zigbee
- Cognitive radio
- LTE
In addition modules are available for sink hole attack, Intrusion detection, packet encryption, packet capture using Wireshark etc.
Performance metrics[edit]
NetSim provides network performance metrics at various abstraction level such as Network, sub-network, link, node along with a detailed packet trace and event 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 300 customers across 15 countries use NetSim, including BSNL, {[IIT Kharagpur]], BITS Pilani, NIT Surat, NIT Rourkela, 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.
