The Importance of Monitoring Network Traffic
No longer is it enough …
 To only react to problems…you must
also be proactive
 To alarm or alert to an outage or service
degradation….you must receive
information before it occurs ….
 To insure traffic flow from one point to
another…..must insure optimum
performance of that traffic…
 To understand that network , traffic or
applications are slow…you must
understand “why”
 Make assumptions about projected
capacity decisions..you need fact to
justify expenditures / return on
investment (ROI)

The Need to Manage the Network Traffic
Network administrators and corporate executives understand that monitoring the network is important and
vital to business operations. It is not simply enough to know if a device is down or the network is slow.
Network administrators need to be more proactive by monitoring the devices and the network and watching
for trends or deviations from an established baseline.
And when there is a problem, resolving the problem quickly means having the right information to make
decisions. This information can only be obtained by monitoring the application traffic, to understand who is
generating the traffic and where the traffic is going.
Additionally, if more bandwidth is warranted, the recommendations will need to be justified. Network
monitoring can provide this cost justification. Thus, visibility into the performance of networks and the
systems and applications that run on them is essential. By gaining visibility into the network, network
administrators can more proactively resolve problems before they arise, plan for changes in resource usage,
and manage valuable network resources.
Cisco makes this job easier than ever by providing visibility into the network. Cisco is making the network
easier to manage by building intelligence into the devices!
