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 is a metapackage depending on the packages for the CORE daemon and GUI.
