  • Publication number: 20220094612
    Abstract: A network performance degradation detection system is provided. The system receives Key Performance Indicator (KPI) values for devices of different device types running different software versions. The system determines baseline values of a first device type by averaging the KPI values of the different software versions running on devices of the first device type. The system compares KPI values for a first software version running on devices of the first device type with the determined baseline values to produce a set of comparison results. The system applies the set of comparison results to a classification model to determine whether the first software version running on devices of the first device type causes network performance degradation.

  • Patent number: 11275838
    Abstract: A method and system. A dataset is generated according to a code package. The code package includes an image file associated with a container for a tenant in a cloud environment. The dataset includes general information related to security aspects of the image file. The image file includes two or more image layers. A security indicator of the image file is extracted according to the dataset. A security level of the image file is determined by comparing the extracted security indicator of the image file with a security indicator of an authenticated image file. A vulnerability in the image file is identified based on the determined security level. In response to the vulnerability having been identified, the image file is updated with a patch that fixes the identified vulnerability. The patch includes a new image layer added to the two or more image layers in the updated image file.

  • Patent number: 11270226
    Abstract: Systems and methods for ticket classification and response include labeling tickets with a ticket classifier that assigns a ticket label and an associated confidence score to each ticket. Tickets are clustered according to semantic similarity to form ticket clusters. A template associated with each ticket cluster is determined. Templates and the respective ticket clusters are clustered according to semantic similarity to form one or more ticket super-clusters. Tickets that have below-threshold confidence scores are labeled according to the one or more ticket super-clusters. The tickets are automatically responded to.
