README
netcode
netcode is a simple connection based client/server protocol built on top of UDP.
It has the following features:
- Encrypted and signed packets
- Secure client connection with connect tokens
- Connection based protocol built on top of UDP
and protects your game server from the following attacks:
- Zombie clients
- Man in the middle
- DDoS amplification
- Packet replay attacks
netcode is stable and production ready.
How does it work?
Please refer to the second half of this whitepaper: Why can't I send UDP packets from a browser?
For a complete technical specification, read the netcode 1.02 standard.
