According to the development trend of networked devices, the origin of network plug-and-play is introduced. According to the function of network devices and the process of network connection, the general requirements of network plug-and-play are summarized. The address automatic configuration and domain name resolution And the research status and related progress of several key issues that must be solved, such as generation and service discovery and access mechanisms as well as network security. This paper mainly analyzes and compares two feasible network plug-and-play architectures proposed by Microsoft such as UPn P and SUN, and finally summarizes and prospects the development trend of network plug and play and its impact .
