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-perf.cc is a simple UDP example program in DCE. In this task, the student is expected to follow the steps given below:

1. Refer to 'examples/tutorial/second.cc' to understand how to enable PCAP in ns-3 programs.
2. Clone the github repository of ns-3 DCE.
3. Refer to 'example/dce-udp-perf.cc' in ns-3 DCE
4. Modify 'example/dce-udp-perf.cc' to enable PCAP support.
5. Create a patch using 'git diff' command.
6. Submit the patch for evaluation

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