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.

dce-udp-simple.cc is a simple UDP example program in DCE. In this task, the student must add comments in dce-udp-simple.cc to explain the working and structures (e.g. instantiated classes) used in this program. A patch file must be submitted for the evaluation.

Note: installation of ns-3 DCE is not needed to complete this task.
