What is Cisco Intelligent WAN ?

Cisco is a feature bundle embedded in routers, targeted at improving end-user experience when they use applications over Wide Area Network (WAN). Cisco IWAN provides the ability to report your application performance metrics, enables per-application policy for granular control of application bandwidth use (Application Visibilty and Control, AVC), monitors network performance and selects the best path for each Class of Service (Performance Routing, PfR), and optimize application traffic for faster response time and less bandwidth (Wide Area Application Services, WaaS).

Netflow version 9 and IPFIX are the protocols of choices for Cisco IWAN to export information from the routers.
