Information technology - UPnP Device Architecture - Part 8-18: Internet Gateway Device Control Protocol - Wide Area Network Internet Protocol Connection Service
This service definition is compliant with the UPnP Device Architecture version 1.0. This service-type enables a UPnP control point to configure and control IP connections on the WAN interface of a UPnP compliant InternetGatewayDevice*. Any type of WAN interface (e.g., DSL or Cable) that can support a IP connection can use this service. The service is REQUIRED if an IP connection is used for WAN access, and is specified in urn:schemas-upnp-org:device:WANConnectionDevice one or more instances of which are specified under the device urn:schemas-upnp-org:device:WANDevice An instance of WANDevice is specified under the root device urn:schemas-upnp-org:device:InternetGatewayDevice All IP Internet connections are set up from a WAN interface of the InternetGatewayDevice or bridged through the gateway to Internet Service Providers (ISPs). WANDevice is a container for all UPnP services associated with a physical WAN device. It is assumed that clients are connected to InternetGatewayDevice via a LAN (IPbased network). An instance of a WANIPConnection service is activated (refer to SST below) for each actual Internet Connection instance on a WANConnectionDevice. WANIPConnection service provides IP-level connectivity with an ISP for networked clients on the LAN. In accordance with UPnP Architecture version 1.0, the maximum number of WANIPConnection service instances is static and specified in the InternetGatewayDevice description document. A WANConnectionDevice MAY include a WAN{POTS/DSL/Cable/Ethernet}LinkConfig service that encapsulates Internet access properties pertaining to the physical link of a particular WAN access type. These properties are common to all instances of WANIPConnection in a WANConnectionDevice. A WANDevice provides a WANCommonInterfaceConfig service that encapsulates Internet access properties common across all WANConnectionDevice instances.
