+ committee to produce a model for network management, under the
+ direction of the OSI group.</font></p>
+
+ <p><font face="Arial" size="2">This model has four parts:</font></p>
+ <ul>
+ <li><font face="Arial" size="2">Organization </font></li>
+ <li><font face="Arial" size="2">Information </font></li>
+ <li><font face="Arial" size="2">Communication </font></li>

+ <p><font face="Arial" size="2">This is a view of network management from the top-down, divided into
+ four submodels and recognized by the OSI standard.
+ <img border="0" src="../../images/1.gif" align="absmiddle" width="12" height="12"></font></p>
+
+ <p><font face="Arial" size="2">The Organization model
+ <img border="0" src="../../images/2.gif" align="absmiddle" width="12" height="12"> describes the components of network management
+ such as a manager, agent, and so on, and their relationships. The arrangement
+ of these components leads to different types of architecture, which
+ will be discussed later.</font></p>
+
+ <p><font face="Arial" size="2">The Information model is concerned with
+ structure and storage of network management information.
+ <img border="0" src="../../images/3.gif" align="absmiddle" width="12" height="12"> This information is stored
+ in a database, called a management information base (MIB). The ISO
+ defined the structure of management information (SMI) to define the
+ syntax and semantics of management information stored in the MIB. MIBs and SMI will be covered in more depth later.</font></p>
+
+ <p><font face="Arial" size="2">The Communication model deals with how the management data is
+ communicated between the agent and manager process.<img border="0" src="../../images/4.gif" align="absmiddle" width="12" height="12">
+ It is concerned with
+ the transport protocol, the application protocol, and commands and
+ responses between peers.</font></p>
+
+ <p><font face="Arial" size="2">The Functional model addresses the network management applications
+ that reside upon the network management station (NMS).
+ <img border="0" src="../../images/5.gif" align="absmiddle" width="12" height="12"> The OSI network
+ management model categorizes five areas of function, sometimes
+ referred to as the FCAPS model:</font></p>
+ <ul>
+ <li><font face="Arial" size="2">Fault</font></li>
+ <li><font face="Arial" size="2">Configuration</font></li>

+ management system.</font></p>
