Abstract: A network orchestrator may receive from a branch gateway (BG) an indication that the BG has joined a wide area network (WAN). The network orchestrator may assign, based in part on first load information of a first virtual internet gateway (VIG) and second load information of a second VIG, the first VIG as a primary VIG for the BG. The network orchestrator may also transmit a first redistribution cost to the first VIG. The network orchestrator may also transmit a second redistribution cost that is greater than the first redistribution cost to the second VIG.

Abstract: A system for facilitating efficient multicast traffic distribution in a network comprising a plurality of gateway switches is provided. During operation, the system can receive a join request for a first multicast group. The system can select, based on a source selection mechanism, a first datacenter from a plurality of datacenters as a source of a first multicast flow of the first multicast group. Here, a respective datacenter can provide the first multicast flow. The system can also select, based on a receiver selection mechanism, a first gateway switch from the plurality of gateway switches for receiving the first multicast flow. The system can then send, to the remote gateway switches, a control message comprising information indicating the selection of the source and receiver of the first multicast flow. The control message can notify the first gateway switch to request the first flow from the first datacenter.

Abstract: Systems and methods are provided for optimizing resource consumption by bringing intelligence to the key allocation process for fast roaming. Specifically, embodiments of the disclosed technology use machine learning to predict which AP a wireless client device will migrate to next. In some embodiments, machine learning may also be used to select a subset of top neighbors from a neighborhood list. Thus, instead of allocating keys for each of the APs on the neighborhood list, key allocation may be limited to the predicted next AP, and the subset of top neighbors. In some embodiments, a reinforcement learning model may be used to dynamically adjust the size of the subset in order to optimize resources while satisfying variable client demand.

Abstract: Some examples relate to identifying a dynamic network parameter probe interval in an SD-WAN. In an example, a controller may define a probe profile of an uplink in the SD-WAN. The probe profile of the uplink may include a static probe interval and a probe retry value. The controller may determine the value of the network parameter for the uplink, prior to expiration of a static probe timer interval. If the value of the network parameter is in negative deviation with a baseline value of the network parameter, the controller may identify a dynamic probe interval for each successive determination of the value of the network parameter. The identification of the dynamic probe interval for a given successive determination may depend on at least one previously determined value of the network parameter. The controller may initiate duplicate network traffic on a secondary uplink in the SD-WAN.

Abstract: Some examples relate to managing multicast group traffic. In an example, a switch anchor controller receives a request for a multicast group from an associated network switch in a multicast-capable network. The associated network switch registers to the switch anchor controller in the multicast-capable network. In response to the request, the switch anchor controller selects a non-anchor controller in the multicast-capable network to serve the multicast group to the associated network switch. The switch anchor controller provides the information related to the non-anchor controller to the associated network switch, which in response creates a specific multicast tunnel between the associated network switch and the non-anchor controller to transfer multicast traffic related to the multicast group.

Abstract: An end controller, comprising: a processing resource; and a memory resource storing machine-readable instructions to cause the processing resource to: receive, using internet protocol security (IPSec) messages, a plurality of subnetworks that form a route to a branch device via a branch gateway; transfer the plurality of subnetworks to a layer-2-layer-3 module; transfer the plurality of subnetworks to an open shortest path first (OSPF) module; and publish the plurality of subnetworks that form the route to the branch device to a core router using OSPF link state advertisements (LSAs).

Abstract: An example branch gateway includes processing circuitry, memory including instructions, and a plurality of ports. The branch gateway transmits, from a plurality of ports, a first broadcast message. The branch gateway receives, in response to the first broadcast message, response messages on respective ports. The branch gateway determines, based on a receipt order of the response messages, an identifying address from a first response message. The branch gateway assigns the respective port for each response message to a unique VLAN. The branch gateway determines, for each port assigned to a unique VLAN, a link health parameter. The branch gateway selects a primary port to connect to an activation server of a WAN. The branch gateway selects a secondary port to connect to the activation server.

Abstract: An example network orchestrator of a SD-WAN is configured to classify, based on operating health information, each branch gateway of a cluster in an operating health class of a set of operating health classes. A bucketmap is generated based on the classifications of each branch gateway of the cluster. The bucket map may be transmitted to a leader branch gateway of the cluster. Each branch gateway may be reclassified in an operating health class. An updated bucketmap may be transmitted to a leader branch gateway.

Abstract: In some examples, a network device receives first indicators of performances of a plurality of computing environments, and receives second indicators of performances of a plurality of network paths from the network device to the computing environments. The network device aggregates the first indicators and second indicators to produce aggregate indicators of performances of the network paths. The network device selects, based on the aggregate indicators, a selected network path of the plurality of network paths for communication of data through the network device between a client and a computing environment of the plurality of computing environments.
