What is Direct Code Execution (DCE) ?
Direct Code Execution (DCE) is a framework for ns-3 that provides facilities to execute, within ns-3, existing implementations of userspace and kernelspace network protocols or applications without source code changes. For example, instead of using ns-3’s implementation of a ping-like application, you can use the real ping application. You can also use the Linux networking stack in simulations.

In case you have a question, you should first refer to the documentation:
- A manual is available at https://www.nsnam.org/docs/dce/manual/html/index.html
- API/Doxygen documentation on https://www.nsnam.org/docs/dce/doxygen/index.html
And look for answers on the ns3 mailing list https://groups.google.com/forum/#!forum/ns-3-users.
Development is done on github and bugs should be filed at https://github.com/direct-code-execution/ns-3-dce/issues.
The mailing list used to discuss internals is the same as ns3's: ns-developers at isi.edu
DCE is available under the GPLv2 license. A copy is available in the repository.
