As described herein, a system, method, and computer program are provided for orchestrating re-provisioning of network subscriber dedicated network slices. A request is received from an entity for use of a network. Network slice information indicating a plurality of slices of the network dedicated to a plurality of network subscribers is accessed. Provisioning of one of more slices of the plurality of slices to the entity is orchestrated, according to the request.

A method for operation of a broadband access network of a telecommunications network includes: in a first step, a program or configuration information is provided to or received by an orchestrator node or functionality; in a second step, subsequent to the first step, at least one piece of program or control information is provided or transmitted to at least one programmable network node; and in a third step, subsequent to the second step, the at least one piece of program or control information is activated to be executed by the at least one programmable network node.

Some embodiments of the invention provide a forwarding element that can be configured through in-band data-plane messages from a remote controller that is a physically separate machine from the forwarding element. The forwarding element of some embodiments has data plane circuits that include several configurable message-processing stages, several storage queues, and a data-plane configurator. A set of one or more message-processing stages of the data plane are configured (1) to process configuration messages received by the data plane from the remote controller and (2) to store the configuration messages in a set of one or more storage queues. The data-plane configurator receives the configuration messages stored in the set of storage queues and configures one or more of the configurable message-processing stages based on configuration data in the configuration messages.

The present disclosure provides a proxy communication method, a proxy communication device and a network device. The proxy communication method includes transmitting a management request to an NRF entity, and the management request includes at least one of a registration request, a profile update request or a de-registration request.

Various embodiments herein provide techniques for management data analytics (MDA) for a wireless cellular network. The MDAS producer receives the raw data, classifies and analyses the raw data to generate the analytics output. The MDA process may be supported by machine learning techniques, and performed by a MDA service producer and assisted by a MDA service consumer. For example, the MDA service producer may receive training data from the MDA service consumer, and train a machine learning model based on the training data. The MDA service producer may apply the trained machine learning model to the raw data that are associated with network functions (e.g., self-organizing network (SON) functions) to generate output data that indicates a conflict between the network functions and a recommended action to address the conflict. Other embodiments may be described and claimed.

Techniques discussed herein can facilitate edge computing in connection with a variety of deployment scenarios. Various embodiments can facilitate one or more of: deploying UPF(s) (User Plane Function(s)) to support edge computing; removing UPF(s) not needed for edge computing; deploying local DN(s) (Data Network(s)); E2E (Edge-to-Edge) OSS (Operations Support System) deployment scenarios; and providing RAN (Radio Access Network) condition data to support various applications (e.g., autonomous driving).

A method of assigning master controllers is disclosed. The method of assigning master controllers may be performed by any one of a plurality of controllers included in a software-defined network system and may include: establishing an objective function in which the number of flows passing through switches having different master controllers from among the flows entering during a unit duration of time is a decision variable; establishing at least one constraints; and finding a solution that minimizes the decision variable while satisfying the constraints.

A network element (101-104) of a software-defined network is adapted to construct a configuration system on the basis of configuration data received from a controller (105, 106) of the software-defined network. The network element is arranged to transmit, in response to an event indicating a need to verify the configuration system, status information to the controller. The event may include for example a loss and a subsequent reestablishment of a connection between the network element and the controller. The status information indicates a first portion of the configuration data which has been implemented in the configuration system prior to the event. After receiving the status information, the controller is able transmit an appropriate second portion of the configuration data to the network element so as to enable verification of an appropriate portion of the configuration system. Thus, there is no need to verify the whole configuration system after the event.

A system and method are provided to derive Virtual Network Function (VNF) infrastructure and networking requirements from the virtual network function descriptor and network services descriptor definitions (extended). This results in a fully automated system for VIM creation and VNF onboarding in order to prepare the infrastructure for VNF instantiation.
