The newest parts of an international Standard for Universal Plug and Play (UPnP) will help devices to seamlessly cross multivendor and multi-technology networks – another step forward for intelligent homes and offices. Information technology – UPnP Device Architecture ISO/IEC 29341 describes architecture for home connectivity of intelligent appliances, audio and video equipment, wireless devices, and PCs.
'UPnP Device Architecture is designed to support zero-configuration, 'invisible' networking, and automatic discovery for a breadth of device categories in the area of audio, video, and data from a wide range of vendors,' explains Dr Walter von Pattay, secretary of the committee that developed the Standard. 'The real plus is that it's network independent, does not require device drivers, can be implemented using any programming language or operating system, and supports a wide range of applications from AV to home electronic systems that operate lights, shutters, climate, and so on.
'ISO/IEC 29341 will help manufacturers from around the world to comply with the specifications required to make this technology work, so that any compatible device from any vendor can dynamically join/leave a network and interoperate seamlessly.'
UPnP is designed to bring easy-to-use, flexible standards-based connectivity to ad-hoc or unmanaged networks whether in the home, a small business, or in public spaces. It also offers specifications to control and service the home and its appliances from a distance simply and easily, with device control protocols built upon established, open, internet-based communication standards (for example, TCP/IP, UDP, HTTP, XML, and so on).
The multi-part ISO/IEC 29341Standard allows a user interface for, and a bridge to, intelligent appliances and home electronic systems that connect and handle the interworking of AV and sensors for lighting, heating, cooling, shading, security, and multiple other applications. These sensors and actors may also come from different sources as long as they comply with the Standard.
The Standard consists of several parts. The first part, ISO/IEC 29341-1:2011, Information technology – UPnP device architecture – Part 1: UPnP Device Architecture Version 1.0 establishes the fundamental principles and base architecture. Additional parts define specific applications and devices.
