Architecture Overview

Understanding USDN's network architecture will help you make better decisions when setting up your organization and configuring services.

Network Topology​

USDN operates on a Autonomous-Distributed Wide Area Network (AD-WAN) architecture that provides intelligent path selection, centralized policy management, and optimized application performance across distributed locations:

AD-WAN Key Components​

  • Control Plane: Centralized orchestration, policy management, and path optimization
  • Edge Devices: Intelligent edge appliances that enforce policies and select optimal paths
  • Virtual Overlays: Encrypted tunnels that create secure connectivity over public and private networks
  • Transport Independence: Support for multiple WAN transports with automatic failover
  • Application-Aware Routing: Traffic steering based on application requirements and real-time network conditions

Security Architecture​

USDN implements multiple layers of security to protect your data and ensure secure communications:
