Abstract
A health check is generated for at least two member paths between the local SDWAN controller and a remote SDWAN controller, with a set health check probe packets for transmission by the network interface to remote SDWAN controllers. A link cost is determined for each member path from a set of health check response packets received by the network interface. SDWAN network traffic is prioritized for each member path between the local SDWAN controller and the remote SDWAN controller based at least in part on the link cost.
