Patent number: 11888603Abstract: In some examples, a system creates a requirement including EPG selectors representing EPG pairs, a traffic selector, and a communication operator; determines that EPGs in distinct pairs are associated with different network contexts and, for each pair, which network context(s) contains associated policies; creates first data representing the pair, operator, and traffic selector; when only one network context contains the associated policies, creates second data representing a network model portion associated with the only network context and determines whether the first data is contained in the second data to yield a first check; when both network contexts contain the associated policies, also creates third data representing a network model portion associated with a second network context, and determines whether the first data is contained in the second and/or third data to yield a second check; and determines whether policies for the pairs comply with the requirement based on the checks.Type: GrantFiled: January 25, 2021Date of Patent: January 30, 2024Assignee: Cisco Technology, Inc.Inventors: Advait Dixit, Navneet Yadav, Navjyoti Sharma, Ramana Rao Kompella, Kartik Mohanram

Patent number: 11218508Abstract: Systems, methods, and computer-readable media for assurance of rules in a network. An example method can include creating a compliance requirement including a first endpoint group (EPG) selector, a second EPG selector, a traffic selector, and a communication operator, the first and second EPG selectors representing sets of EPGs and the communication operator defining a communication condition for traffic associated with the first and second EPG selectors and the traffic selector. The method can include creating, for each distinct pair of EPGs, a first respective data structure representing the distinct pair of EPGs, the communication operator, and the traffic selector; creating a second respective data structure representing a logical model of the network; determining whether the first respective data structure is contained in the second respective data structure to yield a containment check; and determining whether policies on the network comply with the compliance requirement based on the containment check.Type: GrantFiled: December 12, 2018Date of Patent: January 4, 2022Assignee: CISCO TECHNOLOGY, INC.Inventors: Advait Dixit, Navneet Yadav, Navjyoti Sharma, Ramana Rao Kompella, Kartik Mohanram

Patent number: 11150973Abstract: Aspects of the technology provide methods for aggregating error log data between multiple devices in a network monitoring appliance. A method of the technology can include steps for identifying a plurality of operators running in a network monitoring appliance, instantiating a plurality of sensors, wherein each of the plurality of sensors is associated with a respective one of the plurality of operators, and wherein each sensor is configured to capture error log data of its corresponding operator. In some aspects, the method can further include steps for aggregating error log data from two or more of the plurality of sensors. Systems and machine-readable media are also provided.Type: GrantFiled: October 23, 2017Date of Patent: October 19, 2021Assignee: CISCO TECHNOLOGY, INC.Inventors: Pavan Mamillapalli, Shadab Nazar, Chetan Narsude, Gaurav Gupta, Azeem Suleman, Jagdev Singh Tur, Navjyoti Sharma

Patent number: 10554477Abstract: Systems, methods, and computer-readable media for aggregating and presenting network events in a network environment. In some embodiments, a system can maintain event correlation rules for aggregating \network events occurring in a network based on characteristics of previously occurring network events. Network events occurring in the specific network environment can be identified. The network events can be aggregated to form an aggregated network event using the event correlation rules maintained based on the characteristics of previously occurring network events. The aggregated network event can subsequently be presented to a user.Type: GrantFiled: September 13, 2017Date of Patent: February 4, 2020Assignee: CISCO TECHNOLOGY, INC.Inventors: Shadab Nazar, Navneet Yadav, Azeem Suleman, Pavan Mamillapalli, John Thomas Monk, Chetan Narsude, Navjyoti Sharma, Gaurav Gupta
