  • Packet flow classification in spine-leaf networks using machine learning based overlay distributed decision trees
    Patent number: 11206218
    Abstract: Techniques for generating a multi-layer network topology on a managed network are described herein. An example method includes receiving, from an internetworking device in a network, one or more encrypted packets in a flow; generating a classification decision corresponding to the flow by traversing one or more decision trees; and providing the classification decision to a controller of the network.
    Type: Grant
    Filed: April 27, 2020
    Date of Patent: December 21, 2021
    Assignee: Cisco Technology, Inc.

  • Packet flow classification in spine-leaf networks using machine learning based overlay distributed decision trees
    Patent number: 10673765
    Abstract: Techniques for generating a multi-layer network topology on a managed network are described herein. In an embodiment, data that was collected from a plurality of network devices within a managed network is received and analyzed within a multi-layered plurality of decision trees. The plurality of decision trees include a plurality of nodes, one overlay decision tree, and at least one underlay decision tree. The plurality of nodes include a set of logic nodes that communicatively couples the at least one underlay tree to one of the logic nodes on the overlay tree. The received data is then classified by the plurality of multi-layered decision trees.
