Network Simulation
Network simulation is a technique that uses software tools to model and analyze the behavior of computer networks, including protocols, traffic, and devices, in a virtual environment. It allows developers and network engineers to test configurations, predict performance, and identify issues without deploying physical hardware. Common applications include protocol development, network design validation, and cybersecurity testing.
Developers should learn network simulation when working on network-intensive applications, such as IoT systems, cloud infrastructure, or distributed systems, to prototype and debug network interactions efficiently. It is crucial for testing scalability, latency, and reliability in controlled scenarios, reducing costs and risks associated with real-world deployments. Use cases include simulating large-scale networks for research, validating routing protocols, or assessing the impact of network changes on application performance.
