SD-WAN (Software Defined WAN)Presentation title here—edit on Slide Master is a specific application of software-defined networking (SDN)technology applied to WAN connections, which are used to connectenterprise networks – including branch offices and data centers –over large geographic distances23

DMPO – Dynamic Multipath OptimizationPresentation title here—edit on Slide Master automatic link monitoring, autodetection of provider and auto-configuration of link characteristics, routing andQOS settings Ondemand, Per-packet link steering based on the measured performance metric, intelligent application learning,business priority of the application, and link cost Delivers sub-second protection to improve application availability Remediates link degradation through forward error correction, activating jitter buffering and synthetic packetproduction.24
