Although the problem was solved in TCP 20 years ago, it is not solved in RakNet or SA-MP, mainly because nobody has bothered using it as an attack before.

The slot consumption isn't the real issue here. Losing slots during an attack is obviously bad. But the high processing caused by all the packets is knocking existing players out of the game. That is what I'll look to solve initially.
Well, it was solved, but as I mentioned, "completing handshake" causes new kind of attack: http://en.wikipedia.org/wiki/SYN_flood

And it could be the issue if it would be implemented in samp.

If I am not wrong, that high processing thing when server is flooded with "incoming connection" packets is caused by protection against "server full attack". Now with ip spoofing attack there is another "server full" exploit and new DoS attack caused by protection against "server full attack"...

Anyway, good luck.
