🔗 synclink-protocol

SyncLink binary protocol — edge-cloud sync, HDLC framing, 16-bit header, 32-bit timestamps.

What It Does

Efficient binary protocol for synchronizing agent state between edge devices (Jetson, Raspberry Pi) and cloud infrastructure. Optimized for low-bandwidth, high-latency connections.

Protocol Specification

• HDLC Framing — Proven serial framing with escape sequences
• 16-bit Header — Compact message type and length encoding
• 32-bit Timestamps — Millisecond precision, year 2038 safe
• CRC-16 Checksum — Error detection on every frame

Message Types

• SYNC_REQUEST — Edge requests state update
• SYNC_RESPONSE — Cloud sends delta state
• HEARTBEAT — Keep-alive with health payload
• BOTTLE — Agent-to-agent message transport
