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.

Abstract: Techniques are described for performing subscriber aware two-way active measurement protocol (TWAMP) data session provisioning between two endpoints in a computer network. For example, the disclosed techniques include extending TWAMP control messaging to include a communication mode for negotiating subscriber-aware TWAMP data monitoring. If the communication mode is supported by both endpoints, a subscriber identifier is specified when a TWAMP data session is provisioned (negotiated) over the control session. The disclosed techniques further include extending TWAMP data messaging to include the subscriber identifier in each test packet for the data session. In this way, each of the endpoints may identify a subscriber corresponding to one or more received TWAMP test packets based on the subscriber identifier included in the received TWAMP test packets.

Abstract: In general, the disclosure describes techniques for assigning traffic originating from an unknown application to a link based on known application quality of experience metrics. For instance, a network device may receive an application data packet of a data flow for an application and determine an application signature of the application data packet. The network device may determine whether the application signature matches an entry in an application signature database, and if the application signature does not match, the network device may identify a class of the application based on one or more characteristics of the application data packet. The network device may then assign the application data packet of the data flow to a first link of a plurality of links based on the class of the application and quality of experience (QoE) metrics for each link.
