%description
GameNetworkingSockets is a basic transport layer for games. The features are:
- Connection-oriented API (like TCP)
- …but message-oriented (like UDP), not stream-oriented
- Supports both reliable and unreliable message types
- Messages can be larger than underlying MTU. The protocol performs fragmentation, reassembly, and retransmission for reliable messages
- A reliability layer significantly more sophisticated than a basic TCP-style sliding window
- Encryption. AES-GCM-256 per packet, Curve25519 for key exchange and cert signatures
- Tools for simulating packet latency/loss, and detailed stats measurement
- Head-of-line blocking control and bandwidth sharing of multiple message streams ("lanes") on the same connection
- IPv6 support
- Peer-to-peer networking
- Cross platform
