Cisco SD-WAN - SD-AVC | Application Visibility and Control - Part 1 (Spanish)

Software-Defined Application Visibility and Control (SD-AVC) is a service that uses the capabilities of Cisco WAN Edge devices to identify, aggregate, and communicate application data in order to make decisions like prioritizing app traffic using QoS, group applications based on business relevance, or choose different network paths based on real-time SLA statistics.

Cisco SD-WAN devices have a Deep Packet Inspection engine integrated that can go up to Layer 7 of the OSI model and recognize thousands of applications. This is absolutely necessary in order to be able to apply policies against a particular app or service.

Some engineers may argue that we have always had DPI engines and app recognition features like Cisco NBAR. However, the key point here is that updating large volumes of new application signatures across the device fleet is not feasible at all using the legacy box-to-box configuration model. You have to operate the network As-a-System to be able to do that at scale, and that is what SD-WAN allows us to do.
