The document explains how to create a UDP broadcast application using Python sockets on both Windows and Linux. It covers important settings like enabling port reuse and binding to network interfaces, along with specific testing scenarios on different hosts and operating systems. The information is valuable for developers working on network applications that require multiple clients and servers.

- 4. Notes: • SO_REUSEPORT enable port reusage so we will be able to run multiple clients and servers on single (host, port). Do not use socket.SO_REUSEADDR except you using linux(kernel<3.9): goto https://stackoverflow.com/questions/14388706/how-do-so- reuseaddr-and-so-reuseport-differ for more information. • For linux hosts all sockets that want to share the same address and port combination must belong to processes that share the same effective user ID! So, on linux(kernel>=3.9) you have to run multiple servers and clients under one user to share the same (host, port). Thanks to @stevenreddie • For Windows OS, it is important to bind it to network interface IP.
