具有目录功能的网络就是用户的概况模板，应用程序以及网络服务通过通用信息模型集成起来的网络．信息模型用于存储网络状态，提供网络信息．本文讨论了ＤＥＮ 的网络架构和构成ＤＥＮ 信息模型的三个组成部分，分析了与目录交换的四种信息类型，对今后开发具有目录功能网络的应用程序和网络设备具有一定的借鉴作用 A network with directory functionality is the user’s profile, application, and network through which the web services are integrated through a common information model. Information model is used to store network status and provide network information. This article discusses the network architecture of DEN and the three components that make up the DEN information model. It analyzes the four types of information exchanged with the directory, which is of some reference for the future development of applications and network devices with directory function networks
