Why would network management tools use this work and not the Common Information Model (CIM)?
The Common Information Model (CIM) is the standard schema for managing desktop systems. It is being developed by the DMTF (Desktop Management Task Force). Cisco and Microsoft are both active members of the DMTF, and support using CIM for desktop management products. CIM describes manageable objects such as computer systems, network systems, and software packages. Directory service products like Active Directory describe users and the objects they use, such as files, applications, and printers. By extending directory services with networking extensions, the gap between manageable objects and the users who require service from them is bridged. So this work is complementary with CIM, and network management tools will use both. We believe CIM will be used mainly for equipment inventory purposes, and possibly to monitor, troubleshoot, and configure devices. Directory-enabling networks is a higher level service that defines the relationships between networks, users, and network services.
