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

        # Transport configuration
        transports=[
            {

                "config": {
                    "port": 8700,
                    "host": "0.0.0.0"

Best Practices

Network Creation Best Practices

  1. Configuration Management: Use external configuration files
  2. Environment Separation: Different configs for dev/staging/prod
  3. Error Handling: Implement robust error handling and recovery
  4. Monitoring: Set up comprehensive monitoring and logging
  5. Security: Always enable security in production environments

Performance Optimization

  1. Resource Limits: Set appropriate connection and message limits
  2. Transport Selection: Choose optimal transports for your use case
  3. Mod Selection: Only enable mods you actually need
  4. Connection Pooling: Reuse connections when possible
  5. Caching: Implement appropriate caching strategies

Security Considerations

  1. Authentication: Always require authentication in production
  2. Encryption: Enable TLS for all transports
  3. Access Control: Implement proper authorization
  4. Audit Logging: Log all important network events
  5. Secret Management: Use secure secret storage
