AVC works by enabling the software features within the Cisco ASR 1000 and Cisco ISR G2 in conjunction with network management tools to perform the following functions:
● Application recognition: Uses Deep Packet Inspection (DPI) to recognize and identify applications regardless of port number.
● Performance monitoring: Uses embedded monitoring capabilities within the routers to extract and collect application usage and performance metrics, and then aggregate and export this information to network management tools using an open export format such as NetFlow Version 9 and IP Flow Information Export (IPFIX).
● Network management: Enables Cisco and third-party network management tools to provide visualization of application bandwidth and performance to end users, as well as providing feedback and implementing policy on network devices to fine-tune performance.
● Control: Controls per-application bandwidth usage and intelligently selects the path to deliver applications based on real-time performance.
