ISO/IEC 29341-8-4:2008

Overview

ISO/IEC 29341-8-4:2008 - Information technology - UPnP Device Architecture - Part 8-4: Internet Gateway Device Control Protocol - Wide Area Network Connection Device specifies the UPnP template for a WANConnectionDevice. It defines a virtual device container used under an InternetGatewayDevice to model a single logical or physical WAN link (for example a DSL VC, cable, Ethernet or POTS ISP instance). This part of the ISO/IEC 29341 UPnP Device Architecture (edition 1.0, 2008) establishes how link and connection services are organized, named and related for WAN interfaces.

Key topics and requirements

• Device identity and type
  • Mandatory device type: urn:schemas-upnp-org:device:WANConnectionDevice:1.
  • WANConnectionDevice instances are specified under the root InternetGatewayDevice/WANDevice hierarchy.
• Container for link and connection services
  • Models a single link on a WAN interface and contains the relevant WAN*LinkConfig and WAN**Connection services.
  • Handles multiple instances (e.g., DSL Virtual Circuits each mapped to a separate WANConnectionDevice).
• Required and optional services
  • Required (when applicable): WANPPPConnection (for PPP-based connections) and WANIPConnection (for IP-based connections). Multiple instances are allowed; service IDs follow a numbered convention (e.g., WANIPConn1, WANIPConn2).
  • Optional: WANPOTSLinkConfig (POTS), WANDSLLinkConfig (DSL), WANCableLinkConfig (Cable), WANEthernetLinkConfig (Ethernet).
• Service relationships and dependencies
  • The Layer3Forwarding service may reference a WANConnectionDevice instance via the DefaultConnectionService state variable (uses the UDN of the instance).
  • WANCommonInterfaceConfig (in WANDevice) models attributes common across all links.
• Scope and compliance
  • Intended to be implemented by UPnP-compliant Internet gateway devices and modem interfaces to ensure interoperable control and configuration over unmanaged/ad-hoc networks.

Practical applications and users

• Who uses it: router and modem manufacturers, firmware and device software engineers, UPnP stack developers, network equipment integrators, test labs, ISPs and systems integrators who need to expose WAN link/control functions over UPnP.
• Use cases: automatic remote configuration of NAT/port mapping, representing DSL virtual circuits and PPP/IP connections to control points, enabling home and small-business gateway management, and supporting interoperability between consumer gateways and management software.
