[Nel] TCP vs. UDP

Thu, 5 Jul 2001 17:00:13 +0200

Sorry, I'm not the network guru at all, so may be it looks childish ...
+I think you should implement  minimum error checking protocol -
+1. Client sends UDP data to the server
+2. Client wait for confirmation from other end what data was received (use some
+UID for packets to send back as confirmation)
+3. If some timeout expired without confirmation, then client resends its data again
