  • Patent number: 11956116
    Abstract: Network management techniques are described. A controller device of this disclosure manages a device group of a network. The controller device includes processing circuitry in communication with the memory, the processing circuitry being configured to receive, using a programmable diagnosis service executed by the processing circuitry, a programming input, to form, using the programmable diagnosis service, based on the programming input, a resource definition graph that models interdependencies between a plurality of resources supported by the device group, to detect, using the programmable diagnosis service, an event affecting a first resource of the plurality of resources, and to identify, using the programmable diagnosis service, based on the interdependencies modeled in the resource definition graph formed based on the programming input, a root cause event that caused the event affecting the first resource, the root cause event occurring at a second resource of the plurality of resources.

  • Patent number: 10785109
    Abstract: A device may receive a set of design parameters for a network service. The set of design parameters may include information that identifies one or more network functions associated with the network service. The device may determine attribute information associated with a plurality of virtual network functions (VNFs). A VNF, of the plurality of VNFs, may be configurable to perform at least one network function of the one or more network functions. The device may generate a network service design, associated with providing the network service, based on the set of design parameters and the attribute information. The network service design may include information identifying one or more VNFs, of the plurality of VNFs, that are capable of providing the network service in accordance with the set of design parameters. The device may provide information associated with the network service design.

  • Patent number: 10644943
    Abstract: A device receives network data associated with a network that includes network devices interconnected by links at an Internet protocol (IP) layer and an optical layer of the network. The device receives constraints associated with determining a network plan for the network, and determines multiple potential network plans for the network based on the constraints and the network data. The device generates a multilayer and interactive user interface associated with the multiple potential network plans, and provides the multilayer and interactive user interface to a client device. The device receives, from the client device, information indicating an interaction with the multilayer and interactive user interface, and modifies the multilayer and interactive user interface, based on the information indicating the interaction, to generate a modified multilayer and interactive user interface. The device provides, to the client device, the modified multilayer and interactive user interface.
