摘要： In one embodiment, a depassivating circuit includes a battery, a resistive load coupled to the battery, and a magnetic field sensor. The magnetic field sensor detects a presence of a magnetic field. The magnetic field sensor depassivates the battery by causing current from the battery to flow through the resistive load, in response to the presence of the magnetic field. The magnetic field sensor detects removal of the magnetic field. The magnetic field sensor ends depassivation of the battery, in response to the removal of the magnetic field.

摘要： In one embodiment, a device obtains path metrics for a network path used to convey application traffic for an online application. The device discretizes the path metrics into labeled states. The device generates state transition visualization data that represents the labeled states as nodes and transitions between the labeled states as edges connecting the nodes. The device provides the state transition visualization data for display.

摘要： In one embodiment, a traffic inspection service executed by an intermediary device obtains, from a monitoring agent executed by an endpoint device, keying information for an encrypted traffic session between the endpoint device and a remote entity. The traffic inspection service provides a notification to the monitoring agent that acknowledges receipt of the keying information. The traffic inspection service uses the keying information to decrypt encrypted traffic from the encrypted traffic session. The traffic inspection service applies a policy to the encrypted traffic session between the endpoint device and the remote entity, based on the decrypted traffic from the session.

摘要： The techniques herein are directed generally to a “zero-knowledge” data management network. Users are able to share verifiable proof of data and/or identity information, and businesses are able to request, consume, and act on the data—all without a data storage server or those businesses ever seeing or having access to the raw sensitive information (where server-stored data is viewable only by the intended recipients, which may even be selected after storage). In one embodiment, source data is encrypted with a source encryption key (e.g., source public key), with a rekeying key being an encrypting combination of a source decryption key (e.g., source private key) and a recipient's public key. Without being able to decrypt the data, the storage server can use the rekeying key to re-encrypt the source data with the recipient's public key, to then be decrypted only by the corresponding recipient using its private key, accordingly.

摘要： In one embodiment, a method comprises: receiving, by a process, an executed function flow of a daisy chained serverless function-as-a-service (FaaS) function, the executed function flow having been injected with a particular trace identifier in response to an initial event trigger and span identifiers having been injected by each service that was executed; generating, by the process, a serverless flow graph associated with the particular trace identifier based on linking a path of serverless functions according to correlation of the span identifiers between the serverless functions; performing, by the process, a trace-based analysis of the serverless flow graph through comparison to a baseline of expectation; detecting, by the process, one or more anomalies in the serverless flow graph according to the trace-based analysis; and mitigating, by the process, the one or more anomalies in the serverless flow graph.

摘要： In one embodiment, a service in a network computes an expected information gain associated with rerouting traffic from a first tunnel onto a backup tunnel in the network. The service initiates, based on the expected information gain, rerouting of the traffic from the first tunnel onto the backup tunnel. The service obtains performance measurements for the traffic rerouted onto the backup tunnel. The service uses the performance measurements to train a machine learning model to predict whether rerouting traffic from the first tunnel onto the backup tunnel will satisfy a service level agreement (SLA) of the traffic.

摘要： In one embodiment, an illustrative method herein may comprise: initiating, by a device, a transaction trace that passes through a plurality of downstream tracers configured to collect a temporarily cached span of telemetry information regarding the transaction trace; receiving, by the device, an indication of a trigger event at a given span along the transaction trace from a particular one of the plurality of downstream tracers; deciding, by the device and based on the trigger event, whether to trigger a sharing of the temporarily cached span of telemetry information regarding the transaction trace from each of the plurality of downstream tracers; and sending, by the device in response to deciding to trigger the sharing, a signal to the plurality of downstream tracers to cause the plurality of downstream tracers to share their temporarily cached span of telemetry information regarding the transaction trace with a telemetry collector.
