[Josu Lazkano]

Thanks both of you for your replys, I will start with TCP and then I will try TLS.

Best regards.

I'd strongly suggest using TCP.

For comparsion on why it's better, quick searching found the following
page, which - in my opinion - is a reasonable summary:

http://www.laynetworks.com/Comparative%20analysis_TCP%20Vs%20UDP.htm

The "User Datagram Protocol" entry on WikiPedia also has a shorter, yet
still useful summary:
