GameNetworkingSockets – Reliable and unreliable messages over UDP
The moment you say "reliable messages with UDP" you really are saying "we are implementing TCP on our own", which quickly turns into question "why?".<p>By its own admission, the project says: "The reliability layer is a pretty naive sliding window implementation". A bit scary if you really want to have guarantee message is delivered.<p>Also scary part: "Our use of OpenSSL is extremely limited; basically just AES encryption", "we do not support x509 certificates". OpenSSL is difficult, coming up with your own key exchange is likely problematic.<p>So I'm still searching for the answer as to why we need to do this? What's the market for this?<p>P.S. Yes, Valve being the author certainly brings some "reedeming value" to this!
