    Abstract: An example client device includes processing circuitry and a memory including instructions that, when executed by the processing circuitry, cause the client device to undertake certain actions. Certain instructions cause the device to periodically measure active network performance data for a network, calculate expected rewards for the plurality of entry points, select an expected best entry point based on the expected rewards, route data to the selected entry point, measure passive network performance data for the selected entry point, and update a reinforcement learning algorithm, based in part on the measured passive network performance data.

    Abstract: Example implementations relate to determining whether network invariants are violated by flow rules to be implemented by the data plane of a network. In an example, a verification module implemented on a device receives a flow rule transmitted from an SDN controller to a switch, the flow rule relating to an event. The module determines whether the flow rule matches any of a plurality of network invariants cached in the device. If determined that the flow rule matches one of the plurality of network invariants, the verification module determines whether the flow rule violates the matched network invariant. If determined that the flow rule does not match any of the plurality of network invariants, the verification module (1) reports the event associated with the flow rule to a policy management module, (2) receives a new network invariant related to the event from the policy management module, and (3) determines whether the flow rule violates the new network invariant. The verification module generates an alarm if determined that the flow rule violates any of the network invariants.

    Abstract: Example method includes: receiving a network topology and a plurality of network configurations in an intent-based network; determining a number of spots available for runtime monitoring of an intent-based network policy among a plurality of intent-based policy in the intent-based network; determining a plurality of runtime constraints comprising one or more of time, resource capacity, and bandwidth demand based on the network topology and the plurality of network configurations; based on the plurality of runtime constraints, generating a runtime monitoring schedule that comprises at least a flow, a spot assigned for runtime monitoring of the flow, and a runtime monitoring rule to be applied at the assigned spot; and monitoring the flow based on the runtime monitoring schedule at the assigned spot.

    Abstract: A method for verifying network intents may include decomposing at least one network intent into a plurality of sub-verification tasks, generating a set of normalized configurations for a plurality of network devices in a target network based on a set of current configurations for the plurality of network devices and generating a network graph based on the set of normalized configurations and a topology of the target network. The method may further include analyzing the plurality of sub-verification tasks and the network graph to determine if the set of current configurations for the plurality of network devices satisfies the at least one network intent. If the at least one network intent is not satisfied, a report may be generated indicating that the target network is not in compliance. If the at least one network intent is satisfied, information may be provided indicating that target network is in compliance.

    Abstract: Examples provided herein describe a method for managing virtualized network service bundles. For example, a physical processor may implement machine readable instructions to receive a first data packet in a virtual network, determine a first type of the first data packet, determine a first active virtualized network service bundle instance associated with a first virtualized network service bundle that handles the first type of data packet, and direct the first data packet to the first active virtualized network service bundle instance. In some examples, the first virtualized network service bundle may comprise a first set of virtual network functions, and the first virtualized network service bundle may be associated with a set of active virtualized network service bundles instances, where the set of active virtualized network service bundle instances may comprise the first active virtualized network service bundle instance.
