Flow-Based Network Emulator

FlowEmu is an open-source flow-based network emulator, which allows the user to model a communication system via freely connectable modules that implement different types of impairments, queues and departure processes. It comes with a Python toolchain that supports running experiments in a virtual Docker environment or on a hardware testbed. FlowEmu features a web-based Graphical User Interface (GUI) as well as a Message Queuing Telemetry Transport (MQTT) interface. Via these interfaces, the user can change the structure and parameters of the model at runtime and get real-time statistics.
