(see ODMA and Shamrock).
An industry group formed by Microsoft and Cisco to create a common data format for storing information about users, devices, servers, and applications in a common repository. DEN describes mechanisms that enable equipment, such as switches and routers, to access and use directory information to implement policy-based networking.
