Abstract
An initial provisioning by a management plane of the SD-WAN is received from a centralized SD-WAN gateway with static path overlay between the network edge device on a local LAN and the centralized SD-WAN gateway. At runtime, intelligent decision are made about which overlay path to select and when for the new flow over a control plane of the SD-WAN, based on the topology of the remote network edge and the local SDWAN policy, and to build the selected overlay path.
