  • Publication number: 20240098535
    Abstract: Systems and methods for managing traffic in a hybrid environment include monitoring traffic load of a local network to determine whether the traffic load exceeds or is likely to exceed a maximum traffic load, where the maximum traffic load is a traffic load for which a service can be provided by the local network, based on a license. An excess traffic load is determined if the traffic load exceeds or is likely to exceed the maximum traffic load. One or more external networks which have a capacity to provide the service to the excess traffic load are determined, to which the excess traffic load is migrated. The local network includes one or more service instances for providing the service for up to the maximum traffic load, and the service to the excess traffic load is provided by one or more additional service instances in the one or more external networks.

  • Patent number: 11870755
    Abstract: Systems and methods provide for provisioning a dynamic intent-based firewall. A network controller can generate a master route table for network segments reachable from edge network devices managed by the controller. The controller can receive zone definition information mapping the network segments into zones and Zone-based Firewall (ZFW) policies to apply to traffic between a source and destination zone specified by each ZFW policy. The controller can evaluate a ZFW policy to determine first edge network devices that can reach first network segments mapped to the source zone specified by the ZFW policy, second edge network devices that can reach second network segments mapped to the destination zone specified by the ZFW policy, and routing information (from the route table) between the first network segments, the first and second edge network devices, and the second network segments. The controller can transmit the routing information to the edge network devices.

  • Patent number: 11870641
    Abstract: An enterprise controller of an enterprise network sends to a service gateway of a service provider network a request for network slice information about network slices provisioned on a data plane of the service provider network. Responsive to the sending, the enterprise controller receives from the service gateway the network slice information including identifiers of and properties associated with the network slices. Responsive to receiving a request for the network slice information from a network device at a border of a forwarding plane of the enterprise network, the enterprise controller sends the network slice information to the network device to cause the network device to perform configuring network traffic in the forwarding plane with identifiers of ones of the network slices that match the network traffic, and to perform forwarding the network traffic configured with the identifiers to the data plane of the service provider network.

  • Patent number: 11696128
    Abstract: Technologies for systems, methods and computer-readable storage media for reducing the time to complete authentication during inter-technology handovers by reusing security context between 5G and Wi-Fi. Assuming, that the administrative domain for Wi-Fi and 5G match (and belongs to an enterprise for instance), using an already established security context in one technology to do fast authentication in the other technology during handover. Specifically, if UE is on Wi-Fi and handing over to 5G, use its Wi-Fi security context to do fast security setup in 5G, which includes a corresponding method for use when the UE goes from 5G to Wi-Fi.

  • Publication number: 20230179598
    Abstract: Cloud delivered access may be provided. A network device may provide a client device with a pre-authentication virtual network and a pre-authentication address. Next, a policy may be received in response to the client device authenticating. The client device may then be moved to a post-authentication virtual network based on the policy. A post-authentication address may then be obtained for the client device in response to moving the client device to a post-authentication virtual network. Traffic for the client device may then be translated to the post-authentication address.

  • Patent number: 11671450
    Abstract: A mapping system, under administrative control of a Wide Area Network (WAN) controller, can track each host, authorized to access a plurality of Local Area Networks (LANs), in one or more mapping databases including a first network address representing an identifier and a second network addressing representing a locator for each host. The mapping system can receive a request for resolution of a first identifier of a host not presently connected to the network. The mapping system can determine the mapping databases exclude a mapping for the first identifier. The mapping system can update the mapping databases with a first mapping including the first identifier and a first locator corresponding to a honeypot network device. The mapping system can transmit, to one or more LANs of the plurality of LANs, routing information to route traffic destined for the first identifier to the honeypot network device.
