So to make the Really Good Choice(tm), you +should have both and choose according to *figures*. So I would do that +in the following order : + + 1. design a "packet sending" layer which allows messages + sending/receiving with semantics in mind (see Vincent's post in the + same thread). Maybe NeL has already that, I haven't check the + source, sorry. + + 2. implement this layer using TCP. Should be straightforward. + + => gives you a backup implementation + + => gives you basic performance figures + + 3. design and implement UDP implementation_s_ with various + requirements depending on the following parameters: + + - packet loss or not + + - in order delivery or not + + You could start from the easiest (packet loss && out of order <=> + raw UDP) and incrementally develop more complicated ones. + + 4. substitute parts of TCP implementation (chat, position packets, ...) + with the corresponding UDP based protocol + + 5. implement a benchmark and test, test, test, ... ; then go to step 4 + and loop + + +Ok. I don't propose any line of code so you could directly throw this +post to /dev/null but you asked for comments. ;) + +BTW, what is your Linux configuration? I've been stuck with the need to +reinstall everything (X, STLport, freetype) on my debian machine. So it +may be easier to install the Linux distribution your are using at Nevrax +on some spare partition to try to "enter the loop". + +Best regards, +d. +-- + <A HREF="mailto:David.Mentre@inria.fr">David.Mentre@inria.fr</A> + Opinions expressed here are only mine. + +</pre> + + + + + + +<!--endarticle--> + <HR> + <P><UL> + <!--threads--> + <LI> Previous message: <A HREF="000490.html">[Nel] TCP vs. UDP</A></li> + <LI> Next message: <A HREF="000501.html">[Nel] TCP vs. UDP</A></li> + <LI> <B>Messages sorted by:</B> + <a href="date.html#488">[ date ]</a> + <a href="thread.html#488">[ thread ]</a> + <a href="subject.html#488">[ subject ]</a> + <a href="author.html#488">[ author ]</a> + </LI> + </UL> +</body></html> |
