TCP vs Reliable UDP

Question

I am writing an application where the client side will be uploading data to the server through a wireless link.

The connection should be very reliable.The link is expected to break many times and there will be many clients connected to the server.

I am confused whether to use TCP or reliable UDP.

Please share your thoughts.

Thanks.

Answer 1

RUDP is not, of course, a formal standard, and there's no telling if you will find existing implementations you can use. Given a choice between rolling this from scratch and just re-making TCP connections, I'd chose TCP.

Answer 2

To be safe, I would go with TCP just because it's a reliable, standard protocol. RUDP has the disadvantage of not being an established standard (although it's been mentioned in several IETF discussions).

Good luck with your project!
