## Description

Design and implement an efficient program in C/C++ that reliably and efficiently transfers files between two machines that are on the same or two different networks, both running Linux. The program can run in both daemon mode and via a simple command, just as scp). The program should be easy to modify to support streaming applications. Make the program as simple as possible. Don't use complicated packages, such as QUIC.

The program should:

1) Use UDP for data transfer;

2) Use BBR (V3) for congestion control; write your own source code instead of turning on BBR flag in kernel;

3) Work without requiring changes on either machine's router or firewall configuration. You may assume SSH is running on both machines and port 22 is open on both networks.

Please make your solution as simple and elegant as possible, and of course with data transfer performance in mind. You may use any open-source component and/or AI tool, but you need to own your code, i.e., you know and can explain every piece of the final code so that any modification/improvement can be made quickly by you if needed.
