The Common Open Research Emulator (CORE) is a tool for emulating networks in 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.

Key features:

1. Network lab in a box:
- Efficient and scalable.
- Easy-to-use GUI canvas.
- Centralized configuration and control.
2. Runs applications and protocols without modifying them.
3. Real-time connection to live networks:
- Hardware-in-the-loop.
- Distributed with multiple COREs.
4. Highly customizable.
5. The emulated machines can use several resources and programs
installed on the real machine, as tcpdump.
This package provides the daemon that makes the emulated network available for one or several environments.
