yojimbo is a network library for client/server games with dedicated servers.
It's designed around the networking requirements of competitive multiplayer games like first person shooters.
As such it provides a time critical networking layer over UDP, with a client/server architecture supporting up to 64 players per-dedicated server instance.
yojimbo is currently in pre-release for early feedback.
Right now it provides support for:
- Cryptographically secure authentication via connect tokens
- Client/server connection management and timeouts
- Signed and encrypted packets sent over UDP
- Reliable-ordered messages and data blocks
- Packet fragmentation and reassembly
For more details please refer to the roadmap.
