  • Publication number: 20220116806
    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: 11277282
    Abstract: Secure network segmentation using logical subnet segments is described. A single network segment or subnet provided by a third party is mapped into multiple layer-3 virtual or logical segments without requiring separate subnets. This mapping is accomplished by using virtual routing functions (VRFs) per logical subnet segment while retaining a single subnet across the segments. The logical subnet segments interact with the single network segment provided by the third party (ISP). The layer-3 VRF instances are created without the need for separate IP subnet pools per layer-3 segment. Each VRF instance for the various logical subnet segments is mapped to a Virtual Network Identifier (VNI) and Scalable Group Tag (SGT).

  • Publication number: 20220052984
    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.
