Answer
Use raw TCP/UDP sockets, define packet frames, implement chunking, ACK logic, retries, and error correction. Avoid HTTP overhead in ultra-low latency scenarios.
Quick Answer
Build a custom transport protocol in Node.js: use net.createServer() for raw TCP, define a frame format (length-prefixed or delimiter-based), implement a Transform stream to parse frames from the raw byte stream, handle partial frames and buffering, add a connection state machine for handshake/session/teardown. Test with high message rates and lossy network simulation.
