  • Patent number: 10298542
    Abstract: In one embodiment, a networking device in a local area network (LAN) establishes a virtual network overlay in the LAN to redirect traffic associated with a particular node in the LAN to a server for analysis. The networking device receives an indication from the server that at least a portion of the traffic associated with the particular node is trusted for local sending within the LAN and adjusts the virtual network overlay to locally send the trusted portion of the traffic associated with the particular node to one or more other nodes in the LAN without redirection to the server. The networking device collects characteristic information regarding the trusted portion of the traffic sent locally within the LAN via the adjusted virtual network overlay and sends the collected characteristic information to the server for analysis.

  • Patent number: 10299265
    Abstract: In one embodiment, a network of nodes is configured to communicate according to a configuration of a vertical ladder topology as well as monitoring communication in the network, and/or selectively controls whether or not provisioned particular links will be used. One embodiment colors nodes of the network (e.g., a wireless deterministic network) along different paths through the network and marks packets with the color of each traversed node to track a path taken by a packet. One embodiment sends a particular packet through the network and marks over which links the packet traverses and aggregates these traversed links of other copies of the particular packet. One embodiment controls whether or not the provisioned time slots are used based on flooding a control packet through the network with enable or disable information for each of these links.

  • Publication number: 20190141540
    Abstract: In one embodiment, a first actuator in a network of sensors and actuators executes a walker agent configured to adjust an actuation setting of the first actuator. The actuation setting controls an area of coverage of the first actuator when actuated. The executing agent on the first actuator receives one or more sensor measurements from one or more of the sensors that are in communication range of the first actuator. The executing agent also controls, based on the received one or more sensor measurements, the area of coverage of the first actuator by adjusting its actuation setting, in an attempt to optimize coverage of the sensors in the network by the areas of coverage of the actuators. The first actuator unloads the executing walker agent after adjusting the actuation setting of the first actuator and propagates the agent to another one of the actuators in the network for execution.

  • Publication number: 20190116485
    Abstract: In one embodiment, a service receives data indicative of roaming failures along mobility paths in a network. The mobility paths represent ordered series of wireless access points via which wireless clients have accessed the network over time. The service uses, based on the data indicative of the roaming failures, a machine learning-based model to associate mobility path failure metrics with portions of the mobility paths. The service identifies, for a first mobility path, an alternate mobility path that has a lower mobility path failure metric than that of the first mobility path. The service triggers a mobility path reroute for a particular client device in the network on the first mobility path to the alternate mobility path.

  • Publication number: 20190114245
    Abstract: In one embodiment, a node in a network reports, to a supervisory service, histograms of application-specific throughput metrics measured from the network. The node receives, from the supervisory service, a merged histogram of application-specific throughput metrics. The supervisory service generated the merged histogram based on a plurality of histograms reported to the supervisory service by a plurality of nodes. The node performs, using the merged histogram, application throughput anomaly detection on traffic in the network. The node causes performance of a mitigation action in the network when an application throughput anomaly is detected. The node adjusts, based on a control command sent by the supervisory service, a histogram reporting strategy used by the node to report the histograms of application-specific throughput metrics to the supervisory service.

  • Patent number: 10225789
    Abstract: In one embodiment, a supervisory device in a network receives from a plurality of access points (APs) in the network data regarding a network availability request broadcast by a node seeking to access the network and received by the APs in the plurality. The supervisory device uniquely associates the node with a virtual access point (VAP) for the node and forms a VAP mapping between the VAP for the node and a set of the APs in the plurality selected based on the received data regarding the network availability request. One of the APs in the mapping is designated as a primary access point for the node. The supervisory device instructs the primary AP to send a network availability response to the node that includes information for the VAP. The node uses the information for the VAP to access the network via the set of APs in the VAP mapping.
