Scope: This device template is compliant with the UPnP Device Architecture, Version 1.0. WANDevice is a REQUIRED virtual device under the root device urn:schemas-upnp-org:device:InternetGatewayDevice WANDevice is a standalone virtual device and may be included in other root devices if appropriate. Each WAN interface MUST support one Internet connection, but MAY simultaneously support more than one Internet connection. The modeling of connections is described in the Theory of Operation section. Each WANDevice is a virtual instantiation of a physical WAN interface on the Internet gateway. If an InternetGatewayDevice provides multiple WAN physical interfaces to UPnP clients, each of these will typically be included in the device description document as distinct WANDevice instances. However, an implementation may choose to encapsulate more than one physical WAN interface in a single WANDevice. This may be done, for example, in applications that use asymmetric connections like a satellite downlink and POTS uplink. Another example would be where multiple physical WAN interfaces are pooled and presented as one device. Aspects such as load balancing between the pooled resources would be transparent to UPnP clients in this case.
