Abstract: Systems, methods, and computer-readable media for policy splitting in multi-cloud fabrics. In some examples, a method can include discovering a path from a first endpoint in a first cloud to a second endpoint in a second cloud; determining runtime policy table capacities associated with nodes in the path; determining policy distribution and enforcement for traffic from the first endpoint to the second endpoint based on the runtime policy table capacities; based on the policy distribution and enforcement, installing a set of policies for traffic from the first endpoint to the second endpoint across a set of nodes in the path; and applying the set of policies to traffic from the first endpoint in the first cloud to the second endpoint in the second cloud.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: Systems, methods, and computer-readable media for improving debugging and troubleshooting of datacenter networks, and more particularly improving the speed of forwarding/data path related problems without going into ASIC level debugging. A switch could, for example, have a processor which communicates with an ASIC. The processor can receive flow information and a notification from the ASIC, the notification indicating a predefined error condition has been identified in a packet. The processor can modify the ASIC programming based on the notification, such that the ASIC records additional, more-detailed, flow information for the switch. The processor can then receive, from the modified ASIC, the additional flow information. The additional flow information can then be used (either by the processor or by an operator) to identify the exact reason for the errors in the flow path.
