opensynaptic 1.4.2

2-N-2 high-performance protocol stack

OpenSynaptic

2-N-2 high-performance IoT protocol stack — standardises sensor readings into UCUM units, compresses them via Base62 encoding, wraps them in a binary packet, and dispatches over pluggable transporters (TCP / UDP / UART / LoRa / MQTT / CAN).

Prerequisites

• Python 3.11+
• Optional: mysql-connector-python, psycopg[binary], aioquic (see pyproject.toml)

Install

pip install -e .

Windows PowerShell Startup Note

If you see this error when activating a virtual environment:

Activate.ps1 cannot be loaded because running scripts is disabled on this system.

Use the project wrappers and run without activation:

.\scripts\venv-python.cmd -m pip install -e .
.\scripts\venv-python.cmd -m pytest tests/unit tests/integration -q
.\scripts\venv-python.cmd -u src/main.py --help
.\run-main.cmd --help

If you need activation in the current shell only:

Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass
& ".\.venv\Scripts\Activate.ps1"

First-Run Native Auto Repair

On first run, OpenSynaptic now auto-attempts native C binding repair if required runtime libraries are missing.

• Trigger point: first run startup preflight and node initialization failure fallback.
• What it does: runs the same native build pipeline as native-build, then retries node startup once.
• If compiler/toolchain is missing, it returns structured guidance and records environment hints through env_guard.

Disable this behavior only when needed:

$env:OPENSYNAPTIC_AUTO_NATIVE_REPAIR = "0"

Why OpenSynaptic?

OpenSynaptic is not a replacement for MQTT or CoAP — it solves a different problem. While MQTT/CoAP handle transport, OpenSynaptic focuses on what you do with sensor data before it hits the wire.

The Real Problem

When you deploy IoT sensors from different vendors, you face three universal headaches:

Problem	Example
Unit chaos	Sensor A sends "pressure": 101.3, "unit": "kPa", Sensor B sends "p": 14.7, "u": "psi"
Verbose encoding	{"sensor_id": "temp_01", "value": 23.5, "unit": "celsius"} → 62 bytes for 4 bytes of data
Transport fragmentation	Need TCP for reliability, UDP for speed, LoRa for range, CAN for automotive — five different codebases

What OpenSynaptic Does Differently

Layer	Traditional Approach	OpenSynaptic
Semantic normalization	Application code	✅ Built-in UCUM
Payload compression	Optional library (zlib/lz4)	✅ Built-in Base62 + DIFF (60–80% reduction vs. JSON)
Transport abstraction	Rewrite per medium	✅ Single API: TCP/UDP/LoRa/CAN/MQTT
Binary encoding	Custom or Protobuf	✅ Zero-copy pipeline

Performance Comparison (Apples-to-Apples)

The numbers below compare CPU processing time only — what happens inside your application before network transmission. Network latency (which dominates end-to-end delay) is excluded because it depends on your infrastructure, not your protocol choice.

Metric	MQTT + JSON (paho-mqtt)	CoAP (aiocoap)	OpenSynaptic
Processing latency (single sensor, Python)	~150–300 μs	~80–200 μs	9.7 μs
Throughput (single core)	~8K–15K ops/s	~10K–20K ops/s	1.2M ops/s†
Payload size (temperature: 23.5°C)	~60 bytes	~40 bytes	~16 bytes
Compression ratio (vs. JSON)	N/A	N/A	60–80% reduction

OpenSynaptic: batch_fused mode, 16 processes, R5 9600X. See Performance at a Glance.

⚠️ Important: These are protocol + serialization benchmarks, not end-to-end network latency. MQTT/CoAP add 1–10 ms for broker/network round trips — OpenSynaptic would add the same when deployed over real networks. The advantage is in processing efficiency, not physics-defying network speed.

When to Use What

If you need...	Use...
Standard IoT cloud connectivity (AWS IoT, Azure IoT Hub)	MQTT
REST-like request/response over UDP	CoAP
Sensor normalization + compression + multi-transport in one stack	OpenSynaptic
Maximum processing throughput on constrained hardware	OpenSynaptic
Already have a working MQTT/CoAP deployment	Keep it. Add OpenSynaptic for preprocessing.

OpenSynaptic as a Preprocessor

OpenSynaptic doesn't force you to abandon existing infrastructure. Use it as a preprocessing layer before MQTT:

# Standardize and compress sensor data, then send via MQTT
node = OpenSynaptic()
packet, _, _ = node.transmit(sensors=[["temp", "OK", 23.5, "cel"]])
mqtt_client.publish("sensors/data", packet.hex())  # 16 bytes instead of 60

Note: The chart above uses user-provided run data. Because run profiles differ (total, processes, threads, batch, chain_mode), treat it as an engineering reference rather than a strict A/B benchmark.

Chart scale note: bars are shown in approximate microseconds (us) for readability, grouped by percentile for faster cross-CPU comparison.

Note: This simplified view shows only total per-packet CPU processing latency from user-provided batch_fused runs. If you need stage-level timing (standardize_ms / compress_ms / fuse_ms), use --pipeline-mode legacy in single-process mode.

Legacy Mode (Precise Per-Stage Timing)

For accurate per-stage breakdown, use --pipeline-mode legacy with single process only:

python -u src/main.py plugin-test --suite stress --total 1 \
  --chain-mode core --pipeline-mode legacy --processes 1 --threads-per-process 1

Legacy Mode Pipeline Timing Breakdown:

pie title Per-Stage Latency Distribution
    "Standardize (3.8%)" : 3.8
    "Compress (6.3%)" : 6.3
    "Fuse (89.7%)" : 89.7

Key Insight: Fusion (binary packet construction) dominates latency in legacy mode; batch_fused optimization reduces this bottleneck significantly.

⚠️ Legacy Mode Caveats:

• Throughput artificially low (~1-5K pps) due to global lock in result collector, not representative of actual system speed
• Latency data accuracy , but don't use pps metric for performance tuning
• Use batch_fused (above) for realistic performance profiling

packet, aid, strategy = node.transmit(sensors=[["V1", "OK", 3.14, "Pa"]])
node.dispatch(packet, medium="UDP")

Backend	Type	Toolchain Required	Best For
pycore	Pure Python	Optional (C compiler)	Balanced, easy setup
rscore	Rust + FFI	Required (Rust + MSVC/Clang)	Maximum performance

Quick Start:

1. Check what you have:

   python -u src/main.py native-check      # Check toolchain availability
   

2. Build native bindings (for pycore):

   python -u src/main.py native-build      # Build C bindings
   

3. Build Rust backend (optional, for rscore):

   python -u src/main.py rscore-build      # Build Rust core
   python -u src/main.py rscore-check      # Verify installation
   

4. Switch active core (persistent):

   # Use Rust core
   python -u src/main.py core --set rscore --persist
   
   # Or switch back to Python core
   python -u src/main.py core --set pycore --persist

Plugin Config Auto-Sync

Built-in plugin settings are stored in Config.json at:

RESOURCES.service_plugins.<plugin_name>

These entries are auto-created with defaults if missing; plugins remain manual-start and do not auto-run at process
