通用即插即用服务自动发现技术

随着数字家电的普及，家庭网络技术呈现出越来越广阔的市场应用前景。为了实现家庭网络互联设备的操作控制和信息共享，需要采用通用即插即用（UPnP）技术。UPnP充分重用包括IP、传输控制协议（TCP）、数据报协议（UDP）、超文本传输协议（HTTP）和可扩展标记语言（XML）在内的互联网技术标准，提供服务的跨平台自动发现和远程控制。采用UPnP可实现灵活而强大的业务发现能力，能将复杂的网络设备驱动变为简单的远程网络控制，同时还能提供互联设备的操作控制和信息共享。

Automatic Service Discovery in UPnP

Along with the popularization of digital home appliances, the home networking technologies have the prospects for a broader market application. It requires the Universal Plug and Play (UPnP) technology to fulfill control and data transfer of interconnected devices in a home network. The UPnP technology makes full use of the multiple Internet technology standards including Internet Protocol (IP), Transmission Control Protocol (TCP), User Datagram Protocol (UDP), Hypertext Transfer Protocol (HTTP) and Extensible Markup Language (XML) to provide cross-platform automatic service discovery and remote control. UPnP helps implement the flexible and powerful service discovery capability and change complex network device driving into simple remote network control. Moreover, it enables control and data transfer of networked devices.
