Greetings,
UPnP is an architecture for pervasive peer-to-peer network connectivity of
intelligent appliances, wireless devices, and PCs of all form factors. It is
designed to bring easy-to-use, flexible, standards-based connectivity to
ad-hoc or unmanaged networks whether in the home, in a small business,
public spaces, or attached to the Internet. UPnP is a distributed, open
networking architecture that leverages TCP/IP and the Web technologies to
enable seamless proximity networking in addition to control and data
transfer among networked devices in the home, office, and public spaces.
UPnP is more than just a simple extension of the plug and play peripheral
model. It is designed to support zero-configuration, "invisible" networking,
and automatic discovery for a breadth of device categories from a wide range
of vendors. This means a device can dynamically join a network, obtain an IP
address, convey its capabilities, and learn about the presence and
capabilities of other devices. DHCP and DNS servers are optional and are
used only if available on the network. Finally, a device can leave a network
smoothly and automatically without leaving any unwanted state behind.
UPnP leverages Internet components, including IP, TCP, UDP, HTTP, and XML.
Like the Internet, contracts are based on wire protocols that are
declarative, expressed in XML, and communicated via HTTP. IP internetworking
is a strong choice for UPnP because of its proven ability to span different
physical media, to enable real world multiple-vendor interoperation, and to
achieve synergy with the Internet and many home and office intranets. UPnP
has been explicitly designed to accommodate these environments. Further, via
bridging, UPnP accommodates media running non-IP protocols when cost,
technology, or legacy prevents the media or devices attached to it from
running IP.
