A method and a system for network resource management, a network device and a computer-readable storage medium. The method for network resource management may include: acquiring, by a Network Function Virtualization Orchestrator (NFVO) module, a Network Service Descriptor (NSD) and/or a Virtualized Network Function Descriptor (VNFD) from an Operation Support System (OSS) module, wherein the VNFD includes the description of virtual machine resources and container resources; and performing, by a Network Function Management and Orchestration (MANO) system and according to a life cycle deployment policy of an NS or VNF, a life cycle management operation on the NS or VNF in one of a virtual machine mode, a container mode and a hybrid orchestration mode.

In one example, a Network Functions Virtualization Orchestrator (NFVO) obtains a radio service descriptor defining communication parameters for a radio in a virtual Radio Access Network (vRAN). Based on the radio service descriptor, the NFVO determines whether a virtual Distributed Unit (vDU) that is configured in accordance with the communication parameters and a virtual Centralized Unit (vCU) that is configured in accordance with the communication parameters are already instantiated in the vRAN. If it is determined that the vDU or the vCU is not already instantiated, the NFVO automatically instantiates the vDU or the vCU in the vRAN.

There is provided an apparatus comprising at least one processor and at least one memory including a computer program code. The at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to receive from at least one further apparatus information associated with at least two virtual network functions, compare the information associated with the at least two virtual network functions to a determined rule, generate at least one function control based on the comparing, and assign the at least one function control to at least one of the at least two virtual network functions.

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.

Aspects of the subject disclosure may include, for example, storing, in a database, subscriber information associated with a plurality of subscribers of a wireless carrier, the subscriber information comprising first subscriber information associated with a first subscriber of the wireless carrier, the first subscriber information comprising first configuration data for a first router of the first subscriber, the first router being located at a first physical location; wirelessly receiving from a second router of the first subscriber, via a wireless service of the wireless carrier, a first registration request made by the second router, the second router being located at a second physical location; responsive to receiving the first registration request, generating first provisioning information, the first provisioning information being based at least in part upon the first configuration data for the first router that is stored in the database; and wirelessly sending to the second router, via the wireless service of the wireless carrier, the first provisioning information, the first provisioning information enabling the first router and the second router to communicate with one another via the wireless service through a first tunnel mechanism. Other embodiments are disclosed.

There is provided a method for handling the running of software in a network, which is performed by a first node in response to a first request to run software using at least one infrastructure component and at least one function component. Transmission of a second request is initiated towards a second node. The second node manages the at least one infrastructure component. The second request is to deploy the at least one infrastructure component and comprises information indicative of at least one function-as-a-service (FaaS) platform implemented by the at least one infrastructure component to be used to run the software. Transmission of a third request is initiated towards a third node. The third node manages the at least one FaaS platform. The third request is to configure the at least one FaaS platform to run the software.

There is provided a method for network management. Transmission of a request for performance of a management task on the network is initiated towards a second entity (20), which is configured to manage network slices of the network. The request comprises information identifying a first network slice (40) of the network and a first programming construct executable to cause the second entity (20) to identify one or more second network slices of the network that are supporting the first network slice (40) and/or one or more first network nodes (60) of the network supporting the first network slice (40). The request comprises a second programming construct executable to cause the second entity (20) to select the first network slice (40), one or more identified second network slices, and/or one or more identified first network nodes (60), on which to perform the management task.

Embodiments of the present disclosure provides a method and an apparatus for subscribing a notification of a change of a network function. A method for subscribing to notification of a change of a network function may comprise: transmitting (S101) a subscription message to a monitoring network function; and receiving (S102) a notification from the monitoring network function to notify a change from the network function whose status is required to be monitored. The subscription message indicates of the network function. The attribute comprises a serving scope indicating one or more target served area of the network function whose status is required to be monitored. According to embodiments of the present disclosure, a simple and fast implementation for subscribing notification of change of network function may be achieved. Particularly, both the response time and the accuracy of the notification about a change of a subscribed network function may be improved.

Systems and methods are provided for predicting system or network failures, such as a degradation in the services provided by a service provider system or network, a system or network outage, etc. In a discovery phase, failure scenarios that can be accurately predicted based on monitored system events are identified. In an operationalization phase, those failure scenarios can be used to design production run-time machines that can be used to predict, in real-time, a future failure scenario. An early warning signal(s) can be sent in advance of the failure scenario occurring.
