Abstract: A network device may receive a request for a service from an endpoint device located in a first region, and may determine whether destination addresses are identified for the service and the first region. The network device may determine whether the service and the first region are identified in a lookup table, and may receive performance metrics associated with multiple paths in the first region to the destination addresses, based on the service and the first region not being identified in the lookup table. The network device may generate a performance metrics matrix based on the performance metrics, and may identify a best destination and a best path for the service in the first region based on the performance metrics matrix, and may cause, for the endpoint device, a connection to the service to be established via the best destination and the best path for the first region.

Abstract: Example network devices, systems, and methods are disclosed. In an example, a network device includes memory configured to store information associated with one or more service level agreements (SLAs) for applications in a software-defined wide area network (SD-WAN) and an application-based multipath routing (AMR) module including processing circuitry. The AMR module is configured to identify, based on criteria, one or more of the applications for AMR, wherein each criterion of the criteria is associated with a corresponding property of an application. The AMR module is configured to determine a breach of one of the SLAs on each WAN link associated with a first application of the identified one or more applications. The AMR module is configured to apply, in response to determining the breach, AMR for the first application.

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. In response to receiving the application data packet, the network device determines whether a packet size of the application data packet is represented in a reference data store. In response to determining that the packet size is not represented in the reference data store, the network device predicts, based on the reference data store, flow metrics for the packet size for each of a plurality of Wide Area Network (WAN) links. The network device selects a WAN link on which to send the application data packet based on the predicted flow metrics.

Abstract: In some implementations, a proxy device may intercept a client session associated with a client device and a destination device. The proxy device may allocate a first port of the proxy device as a source port of a proxy session for the client session. The proxy device may determine, based on allocating the first port, whether session information associated with the proxy session would match session information associated with another proxy session. The proxy device may initiate the proxy session. A source port of the proxy session is the first port of the proxy device based on a determination that the session information associated with the proxy session would not match session information associated with another proxy session, or is a second port of the proxy device based on a determination that the session information associated with the proxy session would match session information associated with another proxy session.

Abstract: Techniques are disclosed for management of communication sessions of network traffic between client devices and the use of an up-to-date session state to enable seamless failovers between routers. One example technique may prepare each backup router to resume sessions of the active router in event of a failover and cause a redirection of the network traffic to complete the failover to a backup router. In a hot-switchover example, a network device known as a session controller synchronizes the session state information to backup router prior to failure and then, causes the network traffic to be redirected to backup router in response to the active router failure. In a warm-switchover example, the same session controller selects a backup router dynamically after detecting failure to active router, synchronizes session state information to backup router, and trigger routing updates, causing the network traffic to be redirected to the backup router.
