GameNetworkingSockets
A connection-oriented, message-based UDP transport layer for games with reliable/unreliable messaging, encryption, and P2P NAT traversal.
What is GameNetworkingSockets?
GameNetworkingSockets is a transport layer library for multiplayer games that provides reliable and unreliable messaging over UDP. It solves the problem of building robust, low-latency network communication for games by offering features like message fragmentation, encryption, and peer-to-peer NAT traversal. It combines the connection-oriented approach of TCP with the message-oriented efficiency of UDP.
Game developers and engineers building real-time multiplayer games who need a performant, secure, and cross-platform networking solution. It's particularly useful for those requiring P2P connectivity or advanced reliability mechanisms.
Developers choose GameNetworkingSockets for its battle-tested reliability, encryption, and P2P capabilities, which are derived from Valve's experience in multiplayer gaming. Its compatibility with the Steamworks SDK allows seamless integration with Steam services while remaining usable on other platforms under a permissive license.
