ISO/IEC 29341-1-1:20 11(E)UPnP设备架构(以前称为DCP框架)。它定义了控制器或控制点与设备之间的通信协议。对于发现、描述、控制、事件和呈现，UPnP设备架构使用以下协议栈: -UPnP供应商特定信息； -由UPnP定义的信息； -UPnP特定协议，诸如简单服务发现协议(SSDP)、通用事件通知架构(GENA)和本文档中定义的多播事件协议，以及引用的其他协议。SSDP通过多播或单播UDP传递。多播事件通过多播UDP传递。GENA通过HTTP传递。最终，上述所有消息都通过IP传递。本文档的其余条款详细描述了这些协议层中的每一个的内容和格式。

ISO/IEC 29341-1-1:2011(E) The UPnP Device Architecture (formerly known as the DCP Framework). It defines the protocols for communication between controllers, or control points, and devices. For discovery, description, control, eventing, and presentation, the UPnP Device Architecture uses the following protocol stack:
- UPnP vendor-specific information;
- information defined by UPnP;
- UPnPspecific protocols such as the Simple Service Discovery Protocol (SSDP) the General Event Notification Architecture (GENA) and the multicast event protocol defined in this document, and others that are referenced. SSDP is delivered via either multicast or unicast UDP. Multicast events are delivered via multicast UDP. GENA is delivered via HTTP. Ultimately, all messages above are delivered over IP. The remaining clauses of this document describe the content and format for each of these protocol layers in detail.
