Patent number: 11716265Abstract: Systems, methods, and computer-readable media for detecting and reporting anomalies in a network environment for providing network assurance. In some embodiments, a system can determine confidence scores for at least one value of parameters of a network environment defining network events occurring in the network environment. The confidences scores can indicate a frequency that the defined network events have a specific event state. The confidence scores can be monitored to detect an anomaly in the network environment. In response to detecting the anomaly in the network environment, the system can determine a relevant network state of the network environment. The relevant network state of the network environment and the anomaly in the network environment can be presented to a user.Type: GrantFiled: August 13, 2021Date of Patent: August 1, 2023Assignee: Cisco Technology, Inc.Inventors: Shadab Nazar, Pavan Mamillapalli, Azeem Suleman, Jagdev singh Tur, Ayas Pani

Patent number: 11438234Abstract: Systems, methods, and computer-readable media are disclosed for validating endpoint information for nodes in a network. A network assurance appliance is configured to retrieve, from a first leaf node in a network, first endpoint information for a first set of endpoints connected to the first leaf node, wherein the first set of endpoints includes a virtual port channel (VPC) endpoint. The network assurance appliance retrieves second endpoint information from a second node in the network, compares the first endpoint information with the second endpoint information, and identifies an inconsistency when the first endpoint information and the second endpoint information do not match.Type: GrantFiled: December 3, 2020Date of Patent: September 6, 2022Assignee: Cisco Technology, Inc.Inventors: Ayas Pani, Sanchay Harneja, Manali Holankar

Patent number: 11102111Abstract: Systems, methods, and computer-readable media for validating routing table information in a network. A network assurance appliance may be configured to retrieve routing table information from a plurality of nodes in a network fabric. The routing table information includes path information from at least one source node to at least one destination node. A graph representation of the routing table information is constructed with the at least one destination node as a sink vertex for the graph representation. The network assurance appliance determines, for each leaf node in the network fabric, whether the leaf node can reach the sink vertex based on the graph representation and determines that there is a misconfiguration of the network fabric based on whether each leaf node in the fabric can reach the sink vertex.Type: GrantFiled: September 9, 2019Date of Patent: August 24, 2021Assignee: CISCO TECHNOLOGY, INC.Inventors: Ayas Pani, Sanchay Harneja
