A method, apparatus, and computer program product provide for updating configuration parameters of a universal integrated circuit card via dedicated network functions in a 5G system. In the context of a method, the method receives an encapsulation request from a unified data management module, the encapsulation request comprising data for at least one configuration parameter associated with a universal integrated circuit card of a user device. The method generates, in response to the encapsulation request, a secure packet comprising the at least one configuration parameter and a secure packet header. The method also provides the secure packet to the unified data management module for delivery to the user device.

A topology design device for an optical transmission network includes a memory; and a processor to determine a bypass target area as an area to which a bypass route is to be added in the network, the area indicating a region surrounded by nodes and edges, based on an area demand, namely a total value of a demand for communication to be performed via an edge, by referencing a topology management database storing information regarding nodes, edges, and areas in the network, and a demand management database storing demands in the network; and exclude a node from nodes constituting the bypass target area and determining a bypass route from the nodes from which the node has been excluded, based on a node demand, namely a total value of a demand for which each node serves as a start or end point of the demand, by referencing the databases.

The Distributed Software Defined Network (dSDN) disclosed herein is an end-to-end architecture that enables secure and flexible programmability across a network with full lifecycle management of services and infrastructure applications (fxDeviceApp). The dSDN also harmonizes application deployment across the network independent of the hardware vendor. As a result, the dSDN simplifies the network deployment lifecycle from concept to design to implementation to decommissioning.

An artificial intelligence enhanced method for optimizing operational deployment of field resources using network Voronoi Tessellations in combination with the aggregation and consideration of numerous data elements. Resources deployed in the field utilize modes of transportation that are represented by a network topology, which can be influenced by external sources of information that pertain to nodes in the network or nodes in other network topologies, which can be used by an artificial intelligence processor to develop optimized routes for deployed field resources in a continuous manner. The incorporation of these sources of information that can influence the topology of the network is utilized to determine the optimal deployment of field resources.

Embodiments of the present disclosure are directed to protocol state transition and/or resource state transition tracker configured to monitor, e.g., via filters, for certain protocol state transitions/changes or host hardware resource transitions/changes when a host processor in the control plane that performs such monitoring functions is unavailable or overloaded. The filters, in some embodiments, are pre-computed/computed by the host processor and transmitted to the protocol state transition and/or resource state transition tracker. The protocol state transition and/or resource state transition tracker may be used to implement a fast upgrade operation as well as load sharing and or load balancing operation with control plane associated components.

Described embodiments provide systems and methods for upgrading user space networking stacks without disruptions to network traffic. A first packet engine can read connection information of existing connections of a second packet engine written to a shared memory region by the second packet engine. The first packet engine can establish one or more virtual connections according to the connection information of existing connections of the second packet engine. Each of the first packet engine and the second packet engine can receive mirrored traffic data. The first packet engine can receive a first packet and determine that the first packet is associated with a virtual connection corresponding to an existing connection of the second packet engine. The first packet engine can drop the first packet responsive to the determination that the first packet is associated with the virtual connection.

A method is implemented by a switch in a software defined networking (SDN) network managed by a controller to achieve hitless resynchronization during a controller upgrade. The method includes installing an upgraded set of flow entries so that a packet processing pipeline of the switch includes both a non-upgraded set of flow entries and the upgraded set of flow entries, processing non-tunneled packets using the non-upgraded set of flow entries, processing tunneled packets that have a tunnel upgrade status indicator set in a tunnel header using the non-upgraded set of flow entries, while processing tunneled packets that do not have a tunnel upgrade status indicator set in a tunnel header using the upgraded set of flow entries, and processing non-tunneled packets using the upgraded set of flow entries after all switches managed by the controller have installed upgraded flow entries.

Systems, methods, and non-transitory computer-readable storage media for stage upgrades in a network. The system generates graph-data structured based representations of devices in the network, wherein respective attributes of the representations is selected based on respective services provided by the devices to tenants in the network and identities of respective tenants serviced by the devices. Next, the system generates a graph showing a distribution of the devices in the network according to the representations, wherein the representations are interconnected in the graph based on service roles of associated devices with respect to tenants in the network and other devices associated with the tenants. The system then schedules an upgrade of devices based on the graph, the upgrade being scheduled in stages, each stage including devices selected for upgrade in that stage, wherein the devices for each stage are selected by identifying devices having respective representations assigned to that specific stage.

The present invention relates to IoT devices existing in a deployed ecosystem. The various computers in the deployed ecosystem are able to respond to requests from a device directly associated with it in a particular hierarchy, or it may seek a response to the request from a high order logic/data source (parent). The logic/data source parent may then repeat the understanding process to either provide the necessary response to the logic/data source child who then replies to the device or it will again ask a parent logic/data sources for the appropriate response. This architecture allows for a single device to make one request to a single known source and potentially get a response back from the entire ecosystem of distributed servers.
