Application Visibility and Control Release Update
Application Visibility and Control—Phase 1
Network Based Application Recognition (NBAR) provides application-aware control on a wireless network and enhances
manageability and productivity. It also extends Cisco’s Application Visibility and Control (AVC) as an end-to-end solution,
which gives a complete visibility of applications in the network and allows the administrator to take some action on the
same.

NBAR is a deep-packet inspection technology available on Cisco IOS based platforms, which supports stateful L4 - L7
classification. NBAR2 is based on NBAR and has extra requirements such as having a Common Flow Table for all IOS
features which use NBAR. NBAR2 recognizes application and passes on this information to other features like QoS,
NetFlow and Firewall, which can take action based on this classification.
