Network Emulators
Network emulators are software or hardware tools that simulate real-world network conditions, such as latency, bandwidth, packet loss, and jitter, in a controlled environment. They allow developers and network engineers to test applications, services, or devices under various network scenarios without needing physical infrastructure. This helps identify performance issues, validate resilience, and ensure reliability across different network topologies.
Developers should learn and use network emulators when building distributed systems, cloud applications, or IoT devices that rely on network communication, as they enable testing under realistic but reproducible conditions like poor connectivity or high latency. They are essential for performance optimization, debugging network-related bugs, and ensuring applications work reliably in diverse environments, such as mobile networks or global deployments, before deployment to production.
