Network downtime can affect your business and its productivity. When
this happens, it is important that you restore connections as quickly as
possible.
Reactive network management does reduce downtime by responding to
device and link failures. However, a network management solution
provides you with a proactive management capability. This reduces the
number and severity of failures and can help avoid downtime altogether.
Network topology and monitoring information give you an accurate view
of your network's structure and traffic rates. Using this information you
can make changes to the structure of your network to improve its
performance.
Using a network management solution which gives a full view of your
network and actively warns you of problems, reduces the day-to-day
demands on personnel to find and fix problems. This automation allows
people to focus on key management activities.
Network management enables you to make better use of current
equipment, delaying expensive and disruptive upgrades until they are
necessary. Understanding your network also enables you to choose
upgrades that give the best return for any investment.
The key network management functions described here are useful tools
which help to deliver the benefits of network management described in
