Cisco Application Visibility and Control (AVC) provides a powerful, pervasive, integrated service management solution based on stateful deep packet inspection (DPI). With the Cisco AVC solution, the Cisco ASR 1000 series Aggregation Service Routers (ASR 1000s) and Cisco second generation Integrated Services Routers (ISR G2) can identify applications within the traffic flow. They can then collect various application performance metrics on those applications such as bandwidth use, response time, or latency.
