+ <li>
+
+ <font face="Arial" size="2"><b>Controlling complexity</b> – With
+ massive growth in the number of network components, users, interfaces,
+ protocols, and vendors, loss of control of the network and its
+ resources threatens management.</font></li>
+ <li>
+
+ <font face="Arial" size="2"><b>Improved service</b> – Users expect
+ the same or improved service as the network grows and the resources
+ become more distributed.</font></li>
+ <li>
+
+ <font face="Arial" size="2"><b>Balancing various needs</b> – Users
+ must be provided with various applications at a given level of
+ support, with specific requirements in the areas of performance,
+ availability, and security.</font></li>
+ <li>
+
+ <font face="Arial" size="2"><b>Reducing downtime</b> – Ensure high
+ availability of resources by proper redundant design.</font></li>
+ <li>
+
+ <font face="Arial" size="2"><b>Controlling costs</b> – Monitor and
