TCP/IP Tutorial and Technical Overview - IBM Redbooks

key piece to building intelligent networks, where products from multiple vendors
can store and retrieve topology and configuration-related data.
Of special interest is that the DEN specification defines LDAPv3 as the core
protocol for accessing DEN information, which makes information available to
LDAP-enabled clients or network devices, or both.
DEN makes use of the Common information Model (CIM). CIM details a way of
integrating different management models such as SNMP MIBs and DMTF MIFs.
At the time of writing, the most current CIM schema was version 2.12, released in
April of 2006.
More information about the DEN initiative can be found on the founder’s Web at:

12.4.9 Web-Based Enterprise Management (WBEM)
WBEM is a set of standards designed to deliver an integrated set of
management tools for the enterprise. By making use of XML and CIM, it
becomes possible to manage network devices, desktop systems, telecom
systems and application systems, all from a Web browser. For further
