libyojimbo is a new, easy-to-use library for creating secure client/server network protocols over UDP.
It is designed around the networking requirements of competitive realtime multiplayer games such as first person shooters and action games. As such it provides the absolute fastest, most time critical networking layer over UDP, with a client/server architecture supporting up to 64 players per-dedicated server instance.
libyojimbo is currently in pre-release for early feedback. Right now it provides support for: cryptographically secure authentication, client/server connection management, encryption for packets sent over UDP, reliable-ordered messages and data blocks, plus a serialization framework for extending the protocol with custom messages and packet types.
Current work is focused on implementing MTU fragmentation and reassembly for large UDP packets. After this, work will transition to the matcher, extending it direct client matchmaking requests to dynamically registered server instances with free slots vs. the current example matcher implementation which just directs to a fixed server IP address.
For more details please refer to the roadmap.
