Network Simulator 3 for Advanced Networking Simulation
NS-3 empowers developers to simulate IP networks, validate protocols, and prototype real-world applications in reproducible lab-grade environments.
Enabling ns-3 Simulations for Innovation
Network Simulator 3 (ns-3) is a discrete-event network simulator designed for research, development, and academic use. It supports the simulation of both IP and non-IP based networks and is widely adopted in educational and commercial settings to study network behavior under controlled conditions.
At Cloud Network Test, we enable clients across North America to use ns-3 for testing routing algorithms, wireless technologies, LTE, and internet-scale applications. Based in New York, NY, Cloud Network Test helps organizations perform large-scale simulations with fine-grained performance metrics, enabling robust system modeling and infrastructure optimization.
