  • Patent number: 10826803
    Abstract: Aspects of the subject technology relate to a system configured to receive, from a stream processing service, a first network snapshot segment. The first network snapshot segment is associated with metadata that is used to determine that at least one additional network snapshot segment associated with the output stream has not been previously received. The system is configured to request, from the stream processing service, the at least one additional network snapshot segment and generate a first network snapshot by compiling the first network snapshot segment and the at least one additional network snapshot segment.

  • Patent number: 10798015
    Abstract: Systems, methods, and computer-readable media for flow stitching network traffic flow segments across middleboxes. A method can include collecting flow records of traffic flow segments at a first middlebox and a second middlebox in a network environment including one or more transaction identifiers assigned to the traffic flow segments. Sources and destinations of the traffic flow segments can be identified with respect to the first middlebox and the second middlebox. Corresponding subsets of the traffic flow segments can be stitched together to from a first stitched traffic flow at the first middlebox and a second stitched traffic flow at the second middlebox. The first and second stitched traffic flows can be stitched together to form a cross-middlebox stitched traffic flow across the first middlebox and the second middlebox. The cross-middlebox stitched traffic flow can be incorporated as part of network traffic data for the network environment.

  • Publication number: 20200296007
    Abstract: Systems and methods provide for enriching flow data to analyze network security, availability, and compliance. A network analytics system can capture flow data and metadata from network elements. The network analytics system can enrich the flow data by in-line association of the flow data and metadata. The network analytics system can generate multiple planes with each plane representing a dimension of enriched flow data. The network analytics system can generate nodes for the planes with each node representing a unique value or set of values for the dimensions represented by planes. The network analytics system can generate edges for the nodes of the planes with each edge representing a flow between endpoints corresponding to the nodes. The network analytics system can update the planes in response to an interaction with the planes or in response to a query.

  • Patent number: 10523541
    Abstract: Systems, methods, and computer-readable media for providing interoperability between nodes in separate networks as part of a federated network. In some embodiments, a system can identify a first cluster of nodes in a first network and a second cluster of nodes in a second network. The system can provide interoperability between the first cluster of nodes and the second cluster of nodes. First analytics for the first cluster of nodes can be generated using first network traffic data gathered based on first network traffic flowing through the first cluster of nodes by a group of sensors implemented in the first network. The second cluster of nodes can access the first analytics for the first cluster of nodes as part of providing the interoperability between the first cluster of nodes in the first network and the second cluster of nodes in the second network.

  • Publication number: 20190238633
    Abstract: Aspects of the disclosed technology provide methods for automatically tuning load-balancer configurations in a network environment. In some implementations, a process of the disclosed technology includes steps for collecting flow records of traffic flow segments at a middle box in a network environment, the traffic flow segments corresponding to one or more traffic flows passing through the middle box, analyzing the flow records to identify one or more traffic patterns in the network environment, and automatically updating a load balancer configuration based on the one or more traffic patterns, wherein updating the load balancer configuration improves at least one traffic flow parameter for at least one of the traffic flows passing through the middle box. Systems and machine-readable media are also provided.

  • Publication number: 20190230127
    Abstract: Aspects of the disclosed technology relate to ways to authenticate customer/subscriber access to a policy update stream. A process of the technology can include steps for instantiating a network monitoring device in response to a request, the request comprising one or more configuration parameters for the network monitoring device, and receiving a first certificate from the network monitoring device, wherein the first certificate is based on the one or more configuration parameters. In some aspects, the steps can further include sending the first certificate to a processing pipeline for authentication, wherein the processing pipeline is configured to authenticate the first certificate based on a second certificate received by the processing pipeline from the network monitoring device. Systems and machine readable media are also provided.
