Abstract: Embodiments herein describe using transmission codes for ambient power stations (AMP STAs) so multiple AMP STAs can transmit in parallel to a Wi-Fi access point (AP). In order for the AMP STAs to transmit in parallel, the STAs use different codes. In one embodiment, the AMP STAs can use random timers to determine when they transmit and select a code to use during transmission. Before the timer expires, the AMP STAs can listen to see whether other AMP STAs are using the same code (e.g., a collision), and if so, select a different code. However, some AMP STAs may not have the ability to detect a collision. In that case, the AP can determine collisions for the AMP STAs and instruct the AMP STAs to select different codes.

Abstract: Systems and techniques for dynamically assigning virtual access points (VAPs) to multiple basic service set identifier (MBSSID) sets are described. An example technique includes generating a set of VAPs, where each VAP of the set of VAPs has a non-configured state. A first VAP configuration is received and includes an indication of a physical (PHY) mode associated with the first VAP configuration. A first VAP of the set of VAPs is assigned to a first MBSSID set, based at least in part on the PHY mode. The first VAP is configured according to the first VAP configuration.

Abstract: The disclosed technology relates to a process for optimizing data flow within a computer network. The technology utilizes shared memory and machine learning logic to improve the efficiency of how computing resources are used during a transmission of data packets in the computer network. The shared memory is implemented during the transmission of data packets between the data plane and the service plane so that the copying of data packets after the data packets have been received and processed by an application is not necessary. The machine learning logic is implemented during the processing of the data packets in order to adjust a frequency or extent that the data packets (and corresponding source of the data packets) need to be evaluated to ensure that malicious content is not being transmitted across the computer network.

Abstract: In one embodiment, a method includes evaluating, by a device while traversing a plurality of ordered telemetry spans of a given trace message, whether any of the plurality of ordered telemetry spans are starting point spans of an application transaction and reporting, by the device, metrics corresponding to a particular application transaction based on a corresponding starting point span. The method further includes reporting, by the device, additional metrics from subsequent spans of the plurality of ordered telemetry spans following the corresponding starting point span within a context of the particular application transaction.

Abstract: In one embodiment, a method comprises: evaluating, by a device while traversing a plurality of ordered telemetry spans of a given telemetry trace, whether any of the plurality of ordered telemetry spans are starting points for a respective endpoint flow that represents a possible path taken within a particular application flow; determining, by the device and based on evaluating, one or more particular endpoint flows to be included within a particular application transaction reporting structure associated with the particular application flow; and reporting, by the device, metrics corresponding to the one or more particular endpoint flows within a context of the particular application transaction reporting structure.

Abstract: In one embodiment, a method to authenticate a hardware component, by a system, includes performing a verification process to determine whether the hardware component is authorized to run on the system. The hardware component comprises an electronic fuse storing a hash of a data package and a memory storing the data package, wherein the electronic fuse is configured to provide the hash to the memory. The verification process comprises transmitting a random value (K) to the hardware component to prompt the hardware component to sign a response. The verification process further comprises receiving a signed response containing the random value (K) and the data package, wherein the data package comprises a first serial number associated with the hardware component and a first system number associated with the system. The verification process further comprises decrypting the signed response to verify a value of the random value (K).

Abstract: A method of generating metrics data associated with a microservices-based application comprises ingesting a plurality of spans and mapping an ingested span of the plurality of spans to a span identity, wherein the span identity comprises a tuple of information identifying a type of span associated with the span identity, wherein the tuple of information comprises user-configured dimensions. The method further comprises grouping the ingested span by the span identity, wherein the ingested span is grouped with other spans from the plurality of spans comprising a same span identity. The method also comprises computing metrics associated with the span identity and using the metrics to generate a stream of metric data associated with the span identity.

Abstract: The present disclosure provides systems, methods, and computer-readable media for implementing security polices at software call stack level. In one example, a method includes generating a call stack classification scheme for an application, detecting a call stack during deployment of the application; using the call stack classification scheme during runtime of the application, classifying the detected call stack as one of an authorized call stack or an unauthorized call stack to yield a classification; and applying a security policy based on the classification.

Abstract: Devices, networks, systems, methods, and processes for determining a dynamic bias associated with a network device are described herein. A communication network may include multiple network devices and multiple links between the network devices. The communication network may further include a controller that monitors the communication network to determine dynamic changes in a network topology of the communication network. The controller determines the dynamic bias associated with the network device based on the dynamic changes. The controller generates and transmits a control signal based on the dynamic bias. The network device receives the control signal and switches an operation state of the network device, or an operation state of the links connected to the network device, based on the control signal. The controller can thereby achieve reduction in power consumption of the communication network by switching off the network device without affecting reliability and availability of the communication network.
