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: A network node may receive a packet having an inner internet protocol (IP) header and an outer IP header. The inner IP header may be encrypted. A loose source routing (LSR) field of the outer IP header may identify a recipient address. The network node may determine, based on the recipient address identified in the LSR field, a tunnel endpoint associated with a receiving network node. The network node may update the outer IP header of the packet to obtain an updated packet with an updated outer IP header. A source address of the updated outer IP header may be updated to a tunnel endpoint associated with the network node, and the destination address of the updated outer IP header may be updated to a tunnel endpoint associated with the receiving network node. The network node may route the updated packet according to the updated outer IP header.
