emion 0.3.9

Professional ION-DTN Mission Control & BPv7 Simulation Framework

⚛️ EmION — Professional ION-DTN Simulation

EmION is an authentic, production-ready Delay-Tolerant Networking (DTN) simulation framework. Unlike other simulators, EmION uses the real ION-DTN C-engine and Contact Graph Routing (CGR) for 100% protocol authenticity.

🌍 1. Platform Compatibility

EmION relies on the NASA-JPL ION-DTN C-engine. Choose your platform:

Platform	Support	Recommendation
Linux (Ubuntu/Debian)	✅ Native	Recommended. Use the install.sh for one-click setup.
Windows (WSL2)	✅ Supported	Best for Windows. Install Ubuntu 22.04 on WSL2 and follow Linux steps.
Docker (Any OS)	✅ Containerized	Easiest. Run the pre-built environment with zero local setup.
Windows (Native)	❌ Not Supported	Use WSL2 or Docker. ION-DTN requires a POSIX environment.

🚀 2. Installation

Quick Start (PyPI)

1. Install the framework:

   pip install "emion[dashboard]"
   

2. Setup Dependencies: EmION requires the ION-DTN C-engine. Automatically install everything with:

   emion setup
   

Developer Setup (Source)

For a manual environment setup:

git clone https://github.com/info-gallary/emion.git
cd emion
chmod +x install.sh
./install.sh # Builds everything from source

---

🧪 3. Verification

Ensure your environment is correctly configured by running the professional test suite. This verifies real-time bundle transit and CGR routing:

python3 tests/test_emion.py

🛰️ 4. Usage

Launching Mission Control

Start the visual dashboard to manage multi-node topologies and view live telemetry:

emion dashboard

• URL: http://localhost:8420
• Telemetry: Real-time SDR memory and bundle tracking.
• Visuals: Canvas-based topology with bundle animation.

Command Line Interface

emion info      # Check ION system status
emion dashboard # Start visual UI

🔌 5. Connecting Third-Party Modules (API)

EmION supports selective attachment of Anomaly Detection or Security modules via a FastAPI-based Plugin System.

Step A: Implement your Plugin

Your module must be a web service (FastAPI) with these endpoints:

1. GET /health -> {"status": "ok"}
2. POST /analyze -> Receives bundle payload and metadata, returns:

   {
     "is_anomaly": true,
     "score": 0.95,
     "label": "attack",
     "details": {"reason": "Payload too large"}
   }
   

Step B: Connect to EmION

In the Dashboard UI (or via API), connect your module:

• Module URL: http://localhost:8421
• Target Nodes: Selectively monitor specific nodes (e.g., 1,3) or all.

Demo Reference

See anomaly_detector.py for a functional sample implementation.

🐳 6. Docker (Self-Contained BPv7)

Run the entire EmION environment (ION-DTN + pyion + Dashboard) without local installation.

Build and Run

docker build -t emion .
docker run -p 8420:8420 emion

Access Mission Control at http://localhost:8420.

📦 7. Package Management (Developers)

Build the Package

pip install build twine
python3 -m build

Upload to PyPI

twine upload dist/*
