Abstract: This disclosure describes techniques for providing notifications about events that occur during an online meeting. For instance, a system may establish an online meeting, such as a video conferencing meeting, for users. While in the meeting, a first user may view video of a second user and determine that the second user is experiencing an emergency event. As such, a user device of the first user may receive an input indicating that the emergency event is occurring with the second user. The system may receive the indication from the user device and verify that the emergency event is occurring. Additionally, the system may then send a notification to emergency personnel that indicates at least that the emergency event is occurring and a location of the second user. Furthermore, the system may send notification(s) to contact(s) associated with the second user that indicate at least that the emergency event is occurring.

Abstract: A computer executed process can be configured to identify a network traffic flow of a source network device. The process can select a traffic fidelity rate from a plurality of traffic fidelity rates for sending information regarding the network traffic flow to a digital twin device corresponding to the source network device. The process can transmit the information regarding the network traffic flow to the digital twin device according to the traffic fidelity rate. The digital twin device can be configured to replicate at least one operation of the source network device with respect to the network traffic flow.

Abstract: In one embodiment, an issue analysis service determines that an issue exists with a device in a network. The service searches a decision tree for a solution to the issue, wherein branch nodes of the decision tree comprise diagnostic checks. The service clusters, based on a determination that a solution to the issue does not exist in the decision tree, telemetry for the device with telemetry for one or more other devices that also experienced the issue. The service uses a neural network to identify a difference between the clustered telemetry and telemetry from one or more devices for which the issue was resolved. The service adds a leaf node to the decision tree with the identified difference as a solution to the issue.

Abstract: Aspects of the disclosed technology address the problems of manually identifying and optimizing service chain (SC) performance bottlenecks by providing solutions for automatically identifying and tuning various SC parameters. In some aspects, a SC optimization process of the disclosed technology includes the replication or cloning of a SC for which traffic flow is to be optimized. Traffic flows for the production chain can then be simulated over one or more SC clones to identify and tune individual system parameters, for example, to determine if the simulated changes produce a positive, negative, or neutral change in flow performance. Systems and machine-readable media are also provided.

Abstract: Consumption-based licensing of network features based on blockchained transactions includes receiving, at a server having connectivity to a network including a plurality of network devices, a request from a particular network device of the plurality of network devices for a feature that is licensed in the network on a per-use basis. Feature-specific key blockchain elements and a feature-specific template are generated for the feature and at least one message that includes the feature-specific key blockchain elements and the feature-specific template is sent to the particular network device. The message enables the plurality of network devices to generate one or more blockchain transactions related to consumption of the feature when a usage interval associated with the feature expires.

Abstract: A computer-implemented method is provided for a network controller to implement an update on network elements with minimal disruption. The network controller receives a request to install the update on a number of network elements in one or more networks. Installing the update in each respective network element removes it from operation for an outage duration of time. The network controller determines how network flows will be distributed in the networks due to the outage from installing the update, and generates an update plan that includes timing for installing the update on each network element. The timing is based on how the network flows will be distributed in the networks. The network controller installs the update in each network element according to the timing of the update plan.

Abstract: A testing server tests new code modules, or re-tests previously tested code modules, using individualized sets of test data. The testing server receives test datasets from an execution engine, which runs tested code modules to process operational datasets of computing devices. The testing server receives an untested code module from a user, and obtains test dataset parameters applicable to the untested code module. The testing server generates an individualized set of test datasets based on the test dataset parameters. The testing server tests the untested code module by processing each test dataset in the individualized set of test datasets to produce test results.

Abstract: Systems and methods are described herein for logging system events within an electronic machine using an event log structured as a collection of tree-like cause and effect graphs. An event to be logged may be received. A new event node may be created within the event log for the received event. One or more existing event nodes within the event log may be identified as having possibly caused the received event. One or more causal links may be created within the event log between the new event node and the one or more identified existing event nodes. The new event node may be stored as an unattached root node in response to not identifying an existing event node that may have caused the received event.

Abstract: A client application of a device queries/interrogates a secure device identity module of the device to obtain a device identifier of the device and a signed string generated by the security device identity module using a private key unique to the device. The client application of the device sends to an authorization server a request containing the device identifier and the signed string. Depending on an authentication result obtained for the device based on the device identity, the authorization server sends to the device an access token that enables the client application to access a resource.
