APBR: Application-based load balancing

Security devices support application-based load balancing for advanced policy-based routing (APBR). The APBR achieves load balancing by moving the application traffic in multiple WAN links using user-defined link selection criteria. The link selection criteria for application traffic depends on the link tag and link priority preference settings you defined for the advanced policy-based routing (APBR) interface. The application traffic distribution through the selected links depends on the link weight configuration. This feature improves the application traffic distribution performance for APBR and application quality of experience (AppQoE).
