  • Publication number: 20230421610
    Abstract: Techniques for expressing, communicating, de-conflicting, and enforcing consistent access policies between an IBN architecture and a Cloud-Native architecture. Generally, network administrators and/or users of a Cloud-Native architecture and an IBN architecture express access policies independently for the two different domains or architectures. According to the techniques described herein, a Network Service Endpoint (NSE) of the Cloud-Native architecture may exchange access policies with a network device of the IBN architecture. After exchanging access policies, conflicts between the sets of access policies may be identified, such as differences between allowing or denying communications between microservices and/or applications. The conflicts may be de-conflicted using various types of heuristics or rules, such as always selecting an access policy of the IBN architecture when conflicts arise.

  • Publication number: 20230336402
    Abstract: Data related to operational performance of a plurality of nodes in a system is obtained and a first metric anomaly associated with a node of the plurality of nodes in the system is identified. The first metric anomaly indicates that data associated with a first metric is outside a threshold range. Second metrics related to the first metric are identified and it is determined that one of the second metrics is an anomaly. Third metrics related to the second metric are identified and it is determined whether any third metric is an anomaly. The second metric is identified as a probable cause of the first metric anomaly when it is determined that no third metric is an anomaly. A report including information associated with the probable cause of the first metric anomaly is transmitted to a user device.
