What is PfR?
Performance Routing (PfR) is the latest WAN route optimization from Cisco Systems that utilizes customer's 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 call 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 dynamically and in real-time.
Why implement PfR?
Using PfR benefits network owners in two ways: by reducing bandwidth costs and improving network performance. Many enterprises purchase multiple WAN links multiple carriers, with some links allocated as backups for primary service interruptions. These redundant links cost money yet sit mostly idle. With multiple links, cost savings can be quickly realized by minimizing traffic across those with "tiered-pricing". Beyond cost, multiple links often have different performance characteristics. PfR enables networks to shift traffic as necessary to optimize a variety of chosen metrics, from application performance to bandwidth cost. Further, PfR will reroute traffic to properly operating links when parts of the network have degraded or completely failed.
Who should use PfR?
PfR is appropriate for any enterprise that has a critical private WAN or Internet presence. This technology will benefit any large, medium or small business that has multiple WAN connections. The minimum requirement is just two WAN connections and one LAN connection that can all be connected to only one router.
