  • Patent number: 12231312
    Abstract: In one embodiment, a supervisory service for a network obtains quality of experience metrics for application sessions of an online application. The supervisory service maps the application sessions to paths that traverse a plurality of autonomous systems. The supervisory service identifies, based in part on the quality of experience metrics, a particular autonomous system from the plurality of autonomous systems associated with a decreased quality of experience for the online application. The supervisory service causes application traffic for the online application to avoid the particular autonomous system.

  • Patent number: 12231308
    Abstract: Systems, methods, and computer-readable media are provided for generating a unique ID for a sensor in a network. Once the sensor is installed on a component of the network, the sensor can send attributes of the sensor to a control server of the network. The attributes of the sensor can include at least one unique identifier of the sensor or the host component of the sensor. The control server can determine a hash value using a one-way hash function and a secret key, send the hash value to the sensor, and designate the hash value as a sensor ID of the sensor. In response to receiving the sensor ID, the sensor can incorporate the sensor ID in subsequent communication messages. Other components of the network can verify the validity of the sensor using a hash of the at least one unique identifier of the sensor and the secret key.

  • Patent number: 12231345
    Abstract: Techniques are described for providing service level agreement performance in a link aggregation group computer networking environment. A performance measurement data packet such as a bi-directional forwarding detection (BFD) packet is received. The performance measuring data packet can be considered a parent performance measurement data packet is split into multiple child performance measurement data packets which are each different constituent links of a link aggregation database. The performance of each constituent is tested to determine which constituents satisfy service level agreement parameters. Data packets can then be sent to constituents that meet the data packet's service level agreement performance parameters while still allowing link aggregation grouping.

  • Patent number: 12231456
    Abstract: A system and method are provided for generating a cybersecurity behavioral graph from a log files and/or other telemetry data, which can be unstructured or semi-structured data. The log files are applied to a machine learning (ML) model (e.g., a large language model (LLM)) that generates/extract from the log files entities and relationships between said entities. The entities and relationships can be constrained using a cybersecurity ontology or schema to ensure that the results are meaningful to a cybersecurity context. A graph is then generated by mapping the extracted entities to nodes in the graph and the relationships to edges connecting nodes. To more efficiently extract the entities and relationships from the data file, an LLM is used to generate regular expressions for the format of the log files. Once generated, the regular expressions can rapidly parse the log files to extract the entities and relationships.

A first session is established on behalf of a user device associated with the user account based at least in part on the user account performing a first authentication. A posture associated with the user device is determined. The baseline duration is then adjusted to a dynamic duration based at least in part upon the posture associated with the user device. Based at least in part on the dynamic duration the user can be required to re-authenticate.

  • Patent number: 12231987
    Abstract: This technology allows for determining the location of client devices via radio scanning for triggered orthogonal frequency-division multiple access (“OFDMA”) uplinks. Access points (“APs”) are configured for OFDMA transmissions. A first AP transmits a trigger frame on particular channel to stations in the wireless network. Neighboring APs scan channels for trigger frames (“TF”). Upon detection of a TF, neighboring APs associate a station identifier with a frequency allocation, or resource unit, in the TF. The neighboring APs receive an OFDMA uplink from the stations, determine a received signal strength indicator (“RSSI”) value for each frequency allocation in the OFDMA uplink, and transmit the RSSI values with the associated station identifier to the first AP. The first AP determines the location of each station by mapping a distance value to the RSSI values.

  • Patent number: 12224921
    Abstract: Systems, methods, and computer-readable media for managing compromised sensors in multi-tiered virtualized environments. In some embodiments, a system can receive, from a first capturing agent deployed in a virtualization layer of a first device, data reports generated based on traffic captured by the first capturing agent. The system can also receive, from a second capturing agent deployed in a hardware layer of a second device, data reports generated based on traffic captured by the second capturing agent. Based on the data reports, the system can determine characteristics of the traffic captured by the first capturing agent and the second capturing agent. The system can then compare the characteristics to determine a multi-layer difference in traffic characteristics. Based on the multi-layer difference in traffic characteristics, the system can determine that the first capturing agent or the second capturing agent is in a faulty state.
