[中文适用范围]： 本文件定义了通用即插即用（UPnP）设备架构（UDA）版本 1.0 的协议，用于控制器（或控制点）与设备之间的通信。它涵盖了寻址（步骤 0）、发现（步骤 1）、描述（步骤 2）、控制（步骤 3）、事件通知（步骤 4）和呈现（步骤 5）。该架构利用 TCP/IP 和 Web 技术，支持智能电器、无线设备和各种形式的 PC 之间的普遍对等网络连接。它支持零配置、‘隐形’网络、自动发现，并允许设备动态加入网络、获取 IP 地址、传达其能力、了解其他设备的存在和能力，以及平滑地离开网络。 [外文原描述]： 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.
