Patent attributes
The present invention relates to a software defined networking in a wide area network (SD-WAN) device, comprising a network monitor which observes and gathers network parameters reflecting network conditions and stores them to a database; a metrics collector which receives and gathers node parameters reflecting node status stores them to the database, a traffic manager which performs a traffic evaluation on the network parameters or node parameters to identify if a network traffic level is within a performance range, and a policy engine which performs a mitigation evaluation on the analysis done by the traffic manager to determine if a mitigation strategy must be initiated. If a mitigation strategy must be initiated, the policy engine determines a target node to receive the mitigation strategy and translates the mitigation strategy into a format understandable to the target node and pushes a mitigation command containing the mitigation strategy to the target node.
