Network Plug and Play and Their Architectures

Network plug and play is a new technology of networking developed in recent years, which aims to improve the usability of networks. In this paper,the demands for network plug and play are introduced according to the development of network devices, and the basic requirements of network plug and play are summarized in terms of the functions of network devices and the processes of networking. The present situation in several key issues of network plug and play including the research and achievement on address automatic configuration, domain name resolution,mechanism of service discovery and security of devices are given. The analysis and comparison of two feasible solutions to the architecture of network plug and play,i.e.,Microsoft's UPnP and SUN's Jini,are also presented. Finally,the developing trend and the potential influence of network plug and play are forecast.
