Explanation:
NetFlow facilitates solutions to many common problems encountered by IT professionals.
+ Analyze new applications and their network impact
+ Reduction in peak WAN traffic
+ Troubleshooting and understanding network pain points
Diagnose slow network performance, bandwidth hogs and bandwidth utilization quickly with command line interface or reporting tools.
+ Detection of unauthorized WAN traffic
Avoid costly upgrades by identifying the applications causing congestion.
+ Security and anomaly detection
NetFlow can be used for anomaly detection and worm diagnosis along with applications such as Cisco CS-Mars.
+ Validation of QoS parameters
Confirm that appropriate bandwidth has been allocated to each Class of Service (CoS) and that no CoS is over- or under-subscribed.
Netflow can validate bandwth allocated to each CoS
