Python Socket programming (TCP vs. UDP)

Question

I'm planning to design a server that receives data from multiple clients, the server don't need to send anything back to the client, though STATUS_OK is still cool but not necessary.

I know the basics of Python socket module, twisted framework but my question is, should i use UDP or TCP? The client that need to stay connected at all.

I hope you guys understand my question, thank you for your wonderful help here

Answer 1

You should always use TCP until you have a performance problem that you know can be mitigated with UDP. TCP is easier to understand when it fails.

Answer 2

Can you afford to lose messages? If yes, use UDP. Otherwise use TCP. It's what they're designed for.
