What is PfR?

Performance Routing (PfR) is the latest WAN route optimization technology from Cisco Systems that utilizes customers existing Cisco equipment.

This technology optimizes traffic across two or more WAN connections to both save bandwidth costs and improve network performance.

PfR is an evolution of a prior Cisco technology called Optimized Edge Routing (OER), but with a much broader scope. Integrated within Cisco IOS, PfR gathers operating data from the network itself in order to intelligently route applications based on network performance. All of this happens dynamically and in real time.
