yojimbo

yojimbo is a network library for client/server games written in C++.

It's designed around the networking requirements of competitive multiplayer games like first person shooters.

Generally speaking, if you have a custom game engine written in C++ and you want to network your game, yojimbo is a really good choice.

It has the following features:

Cryptographically secure authentication via connect tokens
Client/server connection management and timeouts
Encrypted and signed packets sent over UDP
Packet fragmentation and reassembly
Bitpacker and serialization system
Unreliable-unordered messages for time sensitive data
Reliable-ordered messages with aggressive resend until ack
Data blocks larger than maximum packet size can be attached to reliable-ordered messages
Estimates of latency, jitter, packet loss, bandwidth sent, received and acked per-connection

yojimbo is stable and production ready.
