This document specifies the characteristics of a device that manages connectivity to the
Internet as an “edge” device between a residential Local Area Network and a Wide Area
Network. The gateway can be physically implemented as a standalone device, or logically as
a set of UPnP devices and services on a PC. This specified device is intended to be
controlled from inside the home network. Control from outside the home network typically
requires access control mechanisms that are outside the scope of this document. This
specified device is also not intended for use with small business networks.
This document defines version 2 of the device named InternetGatewayDevice. It is a UPnP
root device, and is identified by the UPnP device type InternetGatewayDevice:2. It is
compliant with the UPnP Device Architecture, Versions 1.0 and 1.1 ([15] and [16],
respectively). InternetGatewayDevice:2 encapsulates several sub-devices and services that
collectively comprise the Internet Gateway Device Control Protocol (DCP).
Figure 1 is a conceptual illustration of a generic Internet Gateway device consisting of one or
more physical WAN and LAN interfaces.
