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.

摘要： Cloud services are provided by a distributed network including a number of geographically distributed datacenters, to client devices in accordance with data sovereignty requirements. A server within the distributed network may receive a service request and determine whether it complies with the data sovereignty requirements of the client. When the geographic location of the server does not comply with the client's data sovereignty requirements, the server may determine and transmit back to the client device a set of alternative datacenters within the distributed network that comply with the client's data sovereignty requirements. The client device may use network probes to select an alternative datacenter, and the cloud service request of the client device may be migrated from the server to the selected datacenter.

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： The automatic determination of components for Time Sensitive Networking (TSN), and more specifically the automatic determination of the Gate Duration (GD) and Guard Band (GB) for TSN may be provided. To determine the GB and/or GD for a TSN gate, a Time Error (TE) may be determined, and TSN components may be received. An Access Category (AC) and a per-AC Enhanced Distributed Channel Access (EDCA) state may be determined using the TID, wherein the per-AC EDCA includes a Contention Window (CW) minimum. Next, an Arbitration Interframe Space Number (AIFSN) of an upcoming data unit is determined using the using the AC and per-AC EDCA. The GB may be determined based on the AIFSN, the CW minimum, and the TE. The Gate Duration (GD) may be determined based on the TE and calculating a number of symbols in a MAC Protocol Data Unit (MPDU) and the upcoming data unit.

摘要： According to one or more embodiments, a first router receives a latency measurement indicative of latency associated with traffic sent from the first router to a second router. The first router calculates an asymmetrical latency as a difference between the latency measurement and a latency associated with traffic sent from the second router to the first router. The first router determines, based on the asymmetrical latency, a symmetrical latency target. The first router sends, to the second router, an indication of the symmetrical latency target. The first router and the second router adjust their respective de-jitter buffers to achieve the symmetrical latency target between the first router and the second router.

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： Time Sensitive Networking (TSN) in wireless environments may be provided. First, a Radio Frequency (RF) profile associated with a station may be received by a computing device. Next, a number of Transmit Opportunities (TxOPs) to use for transmitting data between an Access Point (AP) and the station based on the received RF profile may be determined. The determined number of TxOPs may then be provided to a wireless controller associated with the AP.

摘要： According to one or more embodiments of the disclosure, a networking device receives a policy for an endpoint in a network. The policy specifies one or more component tags and one or more activity tags that were assigned to the endpoint based on deep packet inspection of traffic associated with the endpoint. The networking device identifies a set of tags for a particular traffic flow in the network associated with the endpoint. The set of tags comprises one or more component tags or activity tags associated with the particular traffic flow. The networking device makes a determination that the particular traffic flow violates the policy based on the set of tags comprising a tag that is not in the policy. The networking device initiates, based on the determination that the particular traffic flow violates the policy, a corrective measure with respect to the particular traffic flow.

摘要： A methodology includes determining a first delay between a first relay and a first label edge router, a second delay between a second relay and a second label edge router, and a third delay of a label-switched path between the first label edge router and the second label edge router. Based on the first, second, and third delays, it is determined whether an end-to-end latency between the first relay and the second relay exceeds an end-to-end latency threshold.
