kcp is a very good udp protocol.
Is it better than e.g. RakNet?
I thought the problem with RakNet was that it was discontinued.
That’s my stand of information as well. Basing anything on discontinued projects does not strike me as a very good idea as it basically means having to maintain it yourself in case of required changes.
Was this library discussed already? It seems to be a continued fork of RakNet:
Very interesting! A well-maintained fork of a library that was already used here would of course be optimal (least required changes/learning curve, I figure).
