The Common Open Research Emulator (CORE) is a tool for emulating networks on one or more machines. You can connect these emulated networks to live networks. CORE consists of a GUI for drawing topologies of lightweight virtual machines, and Python modules for scripting network emulation.
CORE has been developed by a Network Technology research group that is part of the Boeing Research and Technology division. The Naval Research Laboratory is supporting further development of this open source project.

The CORE Documentation covers installation, usage, and more. The CORE Developer's Guide covers the CORE API, which allows other systems to interact with the CORE emulation. This API is also used for communication between the different components of CORE. CORE Python Scripting Documentation is also available.
The latest CORE source and releases are available on GitHub at https://github.com/coreemu/core.
