[REBOL] Re: Rebol and UDP

From: russ::portone::com at: 25-Nov-2000 12:17

Mat, there is nothing guaranteed about UDP (as you said) since it's essentially a "one-way" transmission. It just sends blindly and hopes the packet gets through to someone who wants it. If you want guaranteed connectivity, use TCP or build your own two-way acknowledgement/retry scheme on top of UDP. I cannot say what scheme your game site uses. And I'm not sure you can really do it easily in Rebol since I dunno if you can access the packet identifier word. Someone more knowledgable of the innards of Rebol would have to answer that. If not, you'd need to build some kind of packet ID into the data format of each packet sent... create a timeout on the sending end... resend if you didn't receive an acknowledgement from the receiver in time, etc. Basically, build TCP! :) Hope this helps.
