Overview
ISO/IEC 29341-24-2:2017 - "Information technology - UPnP Device Architecture - Part 24-2: Internet gateway device control protocol - Level 2 - Wide area network connection device" defines the characteristics of the UPnP networked device named WANConnectionDevice, version 2. The standard is compliant with UPnP Device Architecture 1.0 and 1.1 and is part of the ISO/IEC 29341 UPnP series for network device interoperability.
Key topics and requirements
- Device model and type: formal definition of the WANConnectionDevice v2 including device hierarchy and relationships with other UPnP services.
- Device architecture and requirements: mandatory and optional capabilities, service relationships (how WANConnectionDevice integrates with WANDevice and InternetGatewayDevice), and required behavior for interoperability.
- XML device description: standardized XML descriptors for discovery and control by UPnP control points.
- Service references: normative linkage to related UPnP services such as WANIPConnection:2 and WANIPv6FirewallControl:1, and to WAN/LAN device specifications (WANDSLLinkConfig, WANCableLinkConfig, LANHostConfigManagement).
- Testing and conformance: test points and validation requirements to verify correct implementation and UPnP compliance.
- Informative theory of operation: Annex A explains configuration and connection management concepts that guide implementation and troubleshooting.
Practical applications
- Implementing UPnP-capable residential gateways, routers and internet gateway devices that expose WAN connection status and control functions to local control points (e.g., home automation controllers, media servers).
- Enabling standardized features such as remote port mapping, WAN connection status reporting, and IPv6 firewall control via UPnP control protocols.
- Supporting interoperability testing and certification for firmware, device drivers, and network stacks that must conform to UPnP IGD v2 behaviors.
- Providing a reference for software developers building UPnP control points or management tools that interact with wide area network connection devices.
Who should use this standard
- Router and gateway manufacturers, embedded firmware engineers, UPnP implementers, network integrators, test labs, and compliance teams seeking standardized device descriptions, control protocols, and interoperability tests for WAN connection devices.
Related standards and notes
- Part of the ISO/IEC 29341 series (UPnP Device Architecture). Normative references include InternetGatewayDevice:2, WANDevice:2, WANIPConnection:2, WANIPv6FirewallControl:1, WANDSLLinkConfig, WANCableLinkConfig, and LANHostConfigManagement.
- The document includes patent declarations from multiple industry contributors; implementers should review patent information when planning commercial products.
