Application Visibility and Control (AVC) classifies applications using Cisco's Deep Packet Inspection (DPI) techniques with Network-Based Application Recognition (NBAR) engine and provides application-level visibility and control into Wi-Fi network. After recognizing the applications, the AVC feature allows you to either drop or mark the traffic.
Using AVC, the controller can detect more than 1000 applications. AVC enables you to perform real-time analysis and create policies to reduce network congestion, costly network link usage, and infrastructure upgrades.
AVC is supported on the following controller platforms: Cisco 2500 Series Controllers, Cisco 5500 Series Controllers, Cisco Flex 7500 Series Controllers in central switching mode, Cisco 8500 Series Controllers, and Cisco WiSM2.
