Performance Routing (PfR)

Performance Routing (PfR) complements traditional routing technologies by using the intelligence of a Cisco IOS infrastructure to improve application performance and availability. PfR can select the best path for each application based upon advanced criteria such as, reachability, delay, loss, jitter, and mean opinion score (MOS).

PfR can also improve application availability by dynamically routing around network problems like black holes and brownouts that traditional IP routing may not detect. In addition, the intelligent load balancing capability of PfR can optimize path selection based on link use or circuit pricing.
