Network Protocol¶

Client-server communication protocol.

Transport¶

Uses NNG (nanomsg next-gen):

Request/Reply pattern
TCP transport
High performance

Message Format¶

MessagePack serialization:

Request:
{
    "type": "get" | "put",
    "key": [32 bytes],
    "token": "auth-token",
    "data": [bytes]
}

Response:
{
    "status": "ok" | "not_found" | "error",
    "data": [bytes],
    "message": "error message"
}

Operations¶

GET (Lookup)¶

Client → Server: GET(key, token)
Server → Client: OK(data) | NOT_FOUND

PUT (Store)¶

Client → Server: PUT(key, data, token)
Server → Client: OK | ERROR

Performance¶

Metric	Typical
Lookup latency	5-50ms
Store latency	10-100ms
Throughput	~1000 req/s
