PBR provides advantages like Source-Based Transit Provider Selection when multihomed to different providers. This provides cost savings by distributing interactive traffic among low bandwidth, low cost paths and batch traffic over high bandwidth, high cost paths. PBR can be used to implement QoS by classifying and marking packets with IP precedence values in the Type of Service (ToS) field of the IP header. The routers in the core can then implement queuing techniques to prioritize the already marked traffic. PBR can also be used to route the packets over specific traffic engineered paths, which provide the desired QoS through the network.
