Abstract: In an example, a method includes obtaining, for a software-defined wide area network (SD-WAN) system having a plurality of a wide area network (WAN) links for an SD-WAN service, a first service level agreement (SLA) rule that matches a first application, the first SLA rule having a first priority that indicates a priority of the first application; obtaining, for the SD-WAN system, a second SLA rule that matches a second application, the second SLA rule having a second priority that indicates a priority of the second application; assigning, for the SD-WAN system, the first application and the second application to a first WAN link of the plurality of WAN links; and in response to determining that the first WAN link has violated the first SLA rule that matches the first application, assigning, by the SD-WAN system, the second application to a second WAN link of the plurality of WAN links.

Abstract: In general, the disclosure describes techniques for evaluating application quality of experience metrics over a software-defined wide area network. For instance, a network device may receive an application data packet of a data flow for an application and send a first set of probe packets, configured according to an initial probing profile, over each of one or more links. The network device may monitor the data flow to determine one or more characteristics of the data flow and generate an updated probing profile based on the one or more characteristics of the data flow. The network device may then send a second set of one or more probe packets, configured according to the updated probing profile, over each of the one or more links.

Abstract: In general, the disclosure describes techniques for evaluating application quality of experience metrics over a software-defined wide area network. For instance, a network device may receive an application data packet of a data flow for an application. In response to receiving the application data packet, the network device may assign the data flow to a first link of a plurality of links and initiate a probing process for the data flow on the first link to determine one or more quality of experience (QoE) metrics for the first link. The network device may, at a later time, detect that the data flow is no longer being received. In response to detecting that the data flow is no longer being received, the network device may cease the probing process for the data flow on the first link.
