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.

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.
The key use cases for NBAR are capacity planning, network usage base lining and better understanding
of what applications are consuming bandwidth. Trending of application usage helps network admin to
plan for network infrastructure upgrade, improve quality of experience by protecting key applications
from bandwidth-hungry applications when there is congestion on the network, capability to prioritize or
de-prioritize, and drop certain application traffic.
