Patent number: 11750464Abstract: Devices, systems, and techniques for global network state management are described herein. In one example, the present disclosure describes an example method performed by a software-defined network (SDN) controller that manages a network of a plurality of devices. The method include maintaining, by processing circuitry of the SDN controller, global network state information, configuring, by the processing circuitry, a notification service with a subscription for updates to a portion of the global network state information, wherein the notification service is configured to arrange the updates to the portion of the global network state information into a plurality of events, and distributing, by the notification service and via a plurality of interfaces, the plurality of events as event notifications to a plurality of subscriber micro-services of the SDN controller.Type: GrantFiled: March 6, 2021Date of Patent: September 5, 2023Assignee: Juniper Networks, Inc.Inventors: Shivaprasad Gali, Sri Sampath Mallipudi

Patent number: 11665050Abstract: A centralized configuration management system (CCM) may receive, from an NMS device, a request concerning a configuration for a microservice associated with the NMS device. The CCM may identify, based on the request, a first data model associated with default configuration information. The CCM may identify, based on the request, a second data model associated with customized configuration information. The CCM may generate, based on the first data model and the second data model, a response that includes at least one configuration parameter. The CCM may send the response to the NMS device to allow the microservice to be configured based on the at least one configuration parameter.Type: GrantFiled: January 27, 2022Date of Patent: May 30, 2023Assignee: Juniper Networks, Inc.Inventors: Chandrasekhar A, Patricio Giecco, Sri Sampath Mallipudi

Patent number: 11528190Abstract: Techniques are described for in-service configuration data migration for distributed micro service-based applications. In one example, a network device comprises a plurality of legacy data repositories comprising configuration data in key-value pair format that specifies a plurality of parameters and corresponding values for operation of the network device, and a hierarchical configuration data model having a plurality of nodes arranged in a hierarchical organization having a root node and a plurality of leaf nodes. Each of the nodes of the configuration data model is configured to store a set of configuration data parameters for the network device. One or more of the nodes includes a plurality of external references to respective parameters of the plurality of parameters stored within the plurality of legacy data repositories. Process circuitry is configured to perform a migration of the configuration data from the legacy data repositories to the hierarchical data model.Type: GrantFiled: December 31, 2020Date of Patent: December 13, 2022Assignee: Juniper Networks, Inc.Inventors: Sri Sampath Mallipudi, Shivaprasad Gali, Chandrasekhar A
