Abstract: Aggregated health information for a managed network may be retrieved and processed in response to changes to the managed network topology, configuration, or software. In response to receiving notification that a change to a component of the managed network has occurred, a change audit analysis engine can retrieve performance indicator information from components along a traceroute including the component which underwent the change. The retrieved performance indicator information can be processed by a memory based neural network to predict an impact of the change on the aggregated health of the managed network. The predicted impact can be compared to network health information retrieved through an ongoing basis and issues can be determined based on a comparison of the predict impact and the retrieved health information.

Abstract: In one embodiment, a device receives data regarding a wireless client attempting to form an association with a particular wireless access point in a network. The device queries a blockchain ledger in a blockchain database for wireless roaming data regarding the wireless client. The device uses, when available from the blockchain ledger, the roaming data regarding the wireless client to complete the association between the wireless client and the particular wireless access point. The device updates the blockchain ledger with data regarding the association between the wireless client and the particular wireless access point.

Abstract: Systems, methods, and computer-readable media for orchestrating cloud to fog interactions. In some examples, a method can involve partitioning an application into software containers, each of the software containers being configured to host a respective component of the application. The method can further involve identifying nodes on respective hierarchical layers of a hierarchical cloud-fog architecture for hosting the software containers on the respective hierarchical layers of the cloud-fog architecture. The hierarchical cloud-fog architecture can include one or more cloud layers and one or more fog layers. The method can also involve deploying the software containers at the nodes on the respective hierarchical layers of the cloud-fog architecture.

Abstract: Presented herein are methodologies to on-board and monitor Internet of Things (IoT) devices on a network. The methodology includes receiving at a server, from a plurality of IoT devices communicating over a network, data representative of external environmental factors being experienced by individual ones of the plurality of IoT devices at a predetermined location; generating, using machine learning, an aggregated model of the external environmental factors at the predetermined location; receiving, at the server, a communication indicative that a new IoT device seeks to join the network at the predetermined location; receiving, from the new IoT device, data representative of external environmental factors being experienced by the new IoT device; determining whether there is a discrepancy between the external environmental factors of the new IoT device and the aggregated model; and when there is such a discrepancy, prohibiting the new IoT device from joining the network.

Abstract: Automatic, adaptive stimulus generation includes receiving, at a network device that is associated with a network or system, analytics data that provides an indication of how the network or system is responding to a set of test stimuli introduced into the network or system to facilitate an analysis operation. The network device analyzes the analytics data based on an intended objective for the analysis operation and generates control settings based on the analyzing. The control settings control creation of a subsequent stimulus to be introduced into the network or system during subsequent execution of the analysis operation.

Abstract: Disclosed is a system and method of providing a segment routing as a service application. The method includes receiving a configuration of an internet protocol environment. The configuration can be a layer 3 configuration of a single cloud environment or even across multiple cloud environments. The configuration defines routing, forwarding, and paths in the environment between different entities such as virtual machines. The method includes receiving a parameter associated with a workload of a tenant. The parameter can be a service level agreement (i.e., a best bandwidth available), a pathway requirement, a parameter associated with specific workload, and so forth. Based on the configuration and the parameter, the method includes generating tenant-defined layer 3 overlay segment routing rules that define how the workload of the tenant will route data in the internet protocol environment using segment routing.
