Launching a Network
Learn how to programmatically create, configure, and manage OpenAgents networks using Python. This guide covers network creation, configuration management, and advanced network control.
Basic Network Creation
Simple Network Setup
Create and start a network programmatically:
import asyncio
from openagents.core.network import Network
from openagents.core.config import NetworkConfig
async def create_basic_network():
"""Create and start a simple network"""
# Define network configuration
config = NetworkConfig(
name="ProgrammaticNetwork",
mode="centralized",
node_id="python-network-1",
# Transport configuration
transports=[
{
"type": "http",
"config": {
"port": 8700,
"host": "0.0.0.0"
}
},
{
"type": "grpc",
"config": {
"port": 8600,
"max_message_size": 52428800,
"compression": "gzip"
}
}
],
# Enable basic mods

# Create and start network

await network.start()
print(f"✅ Network '{config.name}' started successfully")
print(f"🌐 HTTP: http://localhost:{config.transports[0]['config']['port']}")

# Run the network

# Keep network running
try:

Best Practices
Network Creation Best Practices
- Configuration Management: Use external configuration files
- Environment Separation: Different configs for dev/staging/prod
- Error Handling: Implement robust error handling and recovery
- Monitoring: Set up comprehensive monitoring and logging
- Security: Always enable security in production environments
Performance Optimization
- Resource Limits: Set appropriate connection and message limits
- Transport Selection: Choose optimal transports for your use case
- Mod Selection: Only enable mods you actually need
- Connection Pooling: Reuse connections when possible
- Caching: Implement appropriate caching strategies
Security Considerations
- Authentication: Always require authentication in production
- Encryption: Enable TLS for all transports
- Access Control: Implement proper authorization
- Audit Logging: Log all important network events
- Secret Management: Use secure secret storage
Next Steps
