摘要： Time Sensitive Network (TSN) Quality of Service (QoS) management may be provided. A number of Transmit Opportunities (TxOPs) to use for transmitting data between an Access Point (AP) and a client device over a wireless link may be received. An initial gate configuration to the AP for transmitting data between the AP and the client device over the wireless link for a transmit period of each cycle of a number of cycles may be provided based on the number of TxOPs. A change in a network condition of the wireless link may be detected. The initial gate configuration for the transmit period in a current cycle of the number of cycles may be adjusted in response detecting the change in the network condition of the wireless link.

摘要： The disclosed technology provides solutions that enable scalable and secure data retrieval between microservices by using microservice attributes to encrypt container based data stores. A process of the technology can include steps for: instantiating a first microservice and a second microservice in a cloud environment, wherein the first microservice is associated with a first attribute label and the second microservice is associated with a second attribute label, generating a first key based on the first attribute label and a second key based on the second attribute label, associating a first data store with the first microservice, wherein the first data store is encrypted using the first key, and associating a second data store with the second microservice, wherein the second data store is encrypted using the second key. Systems and machine readable media are also provided.

摘要： Ranging and timing may be provided. A station may send an action frame. The action frame may include an Identifier (ID) associated with an upcoming Timing Measurement (TM)/Fine Timing Measurement (FTM) session. The action frame may indicate a purpose of the upcoming TM/FTM session. Next, the station may send, subsequent to sending the action frame, a TM/FTM session request associated with the action frame. The station may then perform the purpose indicated by the action frame.

摘要： Methods are provided in which a user device connects a participant to a collaboration session in which the participant communicates with at least one other participant using audio and/or video, which is distributed in a media stream to the at least one other participant via a respective user device. In these methods, the user device detects at least one of an object within a space that is included in the video and an audio signal and selectively filters the media stream to exclude the object or a portion of the audio signal based on at least one of participant list information, learned background information, or learned voices of participants of the collaboration session.

摘要： A network controller automatically adjusts a computer network based on the operational information of an industrial device. The network controller receives a notification from a network element in the computer network that the industrial device attached to the network element has an administrative shell. The administrative shell includes operational information describing the operation of the industrial device. The network controller retrieves the administrative shell from the industrial device. The network controller parses the operational information in the administrative shell to determine an intent for the industrial device, and adjusts the computer network based on the intent of the industrial device.

摘要： According to one or more embodiments of the disclosure, a device in a network identifies a packet sent via the network towards an endpoint as being a control packet for the endpoint. The device extracts one or more control parameter values from the control packet. The device compares the one or more control parameter values to a policy associated with the endpoint. The device initiates a corrective measure, based on a determination that the one or more control parameter values violate the policy associated with the endpoint.

摘要： In one embodiment, a network policy engine obtains a substation configuration description for a substation, indicative of intelligent electronic devices (IEDs), associated network communication devices, and related communication configuration information. The network policy engine then creates a mapping of the IEDs and the associated network communication devices based on the substation configuration description, associating each of the IEDs to a corresponding network port of the associated network communication devices. The network policy engine may then further create network control parameters based on the substation configuration description, which comprise defined communication flows for the IEDs and associated security group tags (SGTs) for the defined communication flows. The techniques herein may then cause the SGTs to be imposed at mapped network ports of the network communication devices for the IEDs according to security group access (SGA)-based network control to thereby establish secure network communication for the IEDs within the particular substation.

摘要： A method for teleprotection over a segment routed network comprises receiving network requirements for communication between a first teleprotection relay and a second teleprotection relay, the first teleprotection relay associated with a first router of the segment routed network, and the second teleprotection relay associated with a second router of the segment routed network, identifying a primary path from the first router to the second router satisfying the network requirements, determining a congruent reverse of the primary path satisfies the network requirements, sending, to the first router, the primary path, the first router routing traffic from the first teleprotection relay to the second teleprotection relay using the primary path, and sending, to the second router, the congruent reverse of the primary path, the second router routing traffic from the second teleprotection relay to the first teleprotection relay using the congruent reverse of the primary path.

摘要： According to one or more embodiments of the disclosure, a device obtains one or more System Configuration Description Language files regarding a power utility automation network. The device also obtains traffic data regarding traffic in the power utility automation network. The device trains, using the one or more System Configuration Description Language files and the traffic data, a behavioral model for the power utility automation network that models traffic in the power utility automation network. The device initiates use of the behavioral model in the power utility automation network to identify anomalous traffic behavior in the power utility automation network.
