Network Simulator (Version 2), widely known as NS2, is simply an event- driven simulation tool that has proved useful in studying the dynamic nature of communication networks.
Simulation of wired as well as wireless network functions and protocols (e.g., routing algorithms, TCP, UDP) can be done us- ing NS2.
What is a ns2 simulator?
NS2 stands for Network Simulator Version 2. It is an open-source event-driven simulator designed specifically for research in computer communication networks.
What is ns2 used for?
NS2 is an open-source simulation tool that runs on Linux. It is a discreet event simulator targeted at networking research and provides substantial support for simulation of routing, multicast protocols and IP protocols, such as UDP, TCP, RTP and SRM over wired and wireless (local and satellite) networks.
Which is better ns2 or ns3?
NS3 is not backward compatible with NS2; it’s built from the scratch to replace NS2. NS3 is written in C++, Python Programming Language can be optionally used as an interface. NS3 is trying to solve problems present in NS2. enough (single-language architecture is more robust in the long term).
What is the best network simulator?
Here are the most popular options you can choose from:
- GNS3 (Simulator)
- Packet Tracer (Emulator)
- VIRL Virtual Internet Routing Lab (network simulation platform)
- Boson Network Simulator.
- Build your own lab (real hardware)
