Travis Build Status is a simple connection-oriented protocol built on top of UDP.

It's designed for client server/games with dedicated servers, like first person shooters and e-sports.

It has the following features:

  • Connection oriented protocol over UDP for n clients per-server.
  • Token system so only authenticated clients can connect to your server.
  • Packets sent between client and server are encrypted and signed.

And it's secure by design:

  • Protection against man-in-the-middle attacks.
  • Protection against DDoS amplification attacks.
  • Protection against packet replay attacks.
  • Protection against zombie clients.

Save yourself some time by using instead of writing and testing all this yourself!

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 1.01 standard.
