ISO/IEC 29341-1:2011（E）定义了UPnP技术，该技术描述了智能设备、无线设备和各种形状的PC的普及对等网络连接的体系结构。它旨在将易于使用、灵活、基于标准的连接带到自组织或非托管网络，无论是在家庭、小型企业、公共场所还是连接到互联网。UPnP技术提供了一种分布式、开放的网络体系结构，它利用TCP/IP和Web技术，除了在联网设备之间进行控制和数据传输之外，还可以实现无缝的近距离联网。UPnP设备体系结构（UDA）旨在支持零配置、“不可见”网络，并自动发现来自众多供应商的各种设备类别。设备可以动态加入网络，获取IP地址，传输其功能，并了解其他设备的存在和功能。 最后，设备可以顺利自动离开网络，而不会留下任何不必要的状态。UPnP体系结构中使用的技术包括IP、TCP、UDP、HTTP和XML等互联网协议。与互联网一样，合同基于声明性的有线协议，用XML表示，并通过HTTP进行通信。本国际标准取代2008年出版的ISO/IEC 29341-1第一版，并构成技术修订版。

ISO/IEC 29341-1:2011(E) Defines UPnP technology which describes 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 technology provides 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. The UPnP Device Architecture (UDA) is designed to support zero-configuration, "invisible" networking, and automatic discovery for a breadth of device categories from a wide range of vendors. A device can dynamically join a network, obtain an IP address, convey its capabilities, and learn about the presence and capabilities of other devices. Finally, a device can leave a network smoothly and automatically without leaving any unwanted state behind. The technologies leveraged in the UPnP architecture include Internet protocols such as 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. This International Standard replaces ISO/IEC 29341-1, first edition, published in 2008, and constitutes a technical revision.
