Overview
ISO/IEC 29341-8-17:2008 is an international standard under the UPnP (Universal Plug and Play) Device Architecture series. This part specifically defines the Internet Gateway Device Control Protocol’s Wide Area Network (WAN) Ethernet Link Configuration Service. It models the physical and link layer properties of a WAN Ethernet interface utilized for Internet connectivity in Internet Gateway Devices (IGDs).
Designed to comply with UPnP Device Architecture version 1.0, this standard facilitates seamless and standardized network discovery, control, and management of WAN Ethernet links in devices connected to residential or small business networks. The service targets Internet Gateway Devices with external WAN Ethernet interfaces, such as gateways connected to cable or DSL modems.
By implementing this protocol, devices achieve enhanced interoperability and simplified configuration, enabling flexible ad-hoc and unmanaged network environments at home or in small business and public spaces.
Key Topics
-
Service Type and Identification:
The service provided is identified by the type:
urn:schemas-upnp-org:service:WANEthernetLinkConfig:1. This establishes compliance with this service definition.
-
State Variables:
- EthernetLinkStatus (Read-only): Reflects the current status of the physical WAN Ethernet link between the gateway device and the external modem.
- Allowed values:
Up - Link is activeDown - Link is inactiveUnavailable - Status unknown or not available
- Vendor-specific non-standard state variables may be optionally implemented for extended functionality.
-
Eventing and Monitoring:
The standard supports event notification for changes in EthernetLinkStatus, enabling real-time monitoring. Event moderation ensures efficient management of event rates without flooding the network.
-
Actions Defined:
- GetEthernetLinkStatus: Allows control points to query the current status of the WAN Ethernet link.
- Non-Standard Vendor Actions: Additional proprietary actions may be implemented by vendors but are outside the standard.
-
Theory of Operation:
The service operates by exposing the Ethernet link status of the WAN interface, distinct from the modem’s actual external Internet connection status, focusing only on the physical Ethernet link configuration.
Applications
-
Residential and Small Business Gateways:
Internet Gateway Devices offering WAN connectivity through Ethernet-attached cable or DSL modems can implement this service to standardize the Ethernet link management.
-
Network Diagnostics and Monitoring:
Network administrators and user devices can automatically discover gateway ethernet link status, aiding in troubleshooting and proactive network management.
-
Home Automation and IoT Integration:
Intelligent appliances and devices using UPnP can leverage this service to monitor and respond to changes in the WAN Ethernet link conditions, enhancing system reliability.
-
Public and Unmanaged Networks:
The standard encourages flexible peer-to-peer connectivity in various network scenarios including ad-hoc and unmanaged networks, facilitating device interoperability and ease of use.
