+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. It is based on the "ack vector" model
+  from DCCP (RFC 4340, section 11.4) and Google QUIC and discussed
+  in the context of games by Glenn Fiedler. The basic idea is for the
+  receiver to efficiently communicate to the sender the status of
+  every packet number (whether or not a packet was received with that
+  number). By remembering which segments were sent in each packet,
+  the sender can deduce which segments need to be retransmitted.
+
+- Encryption. AES-GCM-256 per packet, Curve25519 for key exchange
+  and cert signatures. The details for shared key derivation and
+  per-packet IV are based on the design used by Google's QUIC
+  protocol.  Tools for simulating packet latency/loss, and detailed
+  stats measurement IPv6 support Peer-to-peer networking:
