Abstract: Network slicing can provide logical network partitioning. This introduces a high degree of flexibility to support devices with different requirements in terms of quality of service, as well as to optimize the network usage. However, each one of these networks can be used for distinct business purposes. Thus, individual slice surveillance statistics, including failure messages, can be utilized to alert other slices that share the same infrastructure. Thus, an early recovery action can be prompted based on a single slice's anomalies being shared with other slices.

Abstract: The concepts and technologies disclosed herein are directed, in part, to a system that can monitor traffic traversing a virtualized network that includes a plurality of virtual network functions (“VNFs”) that provide, at least in part, a service. The system can capture an event from the traffic. The event can involve at least one VNF, and can negatively affect at least one operational aspect of the virtualized network in providing the service. The system can create snapshot that represents a network state of the virtualized network during the event. The system can create, based upon the snapshot, a shadow network. The shadow network can include a network emulation of the network state of the virtualized network during the event. The system can determine, from the shadow network, at least one modification to at least a portion of the virtualized network that would at least mitigate negative effects of the event.

Abstract: Aspects of the subject disclosure may include, for example, receiving workload requests for tenant devices providing services to user devices; partitioning node resources to facilitate network slicing in a software defined network to provide the services; determining that the workload requests exceed available resources of the node; and outsourcing a portion of a load to one or more neighboring nodes, where the outsourcing is performed in coordination with a regional orchestrator and a SDN intelligence module. Other embodiments are disclosed.

Abstract: A processing system of a cellular network may receive at least a first measurement of at least one network performance indicator associated with the cellular network from at least one of: at least a first channel sounding measurement record from at least a first autonomous vehicle (AV), or a communication from at least one mobile endpoint device or at least one component of the cellular network. The processing system may next identify at a condition of a location based upon the first measurement and may direct at least one of: the first AV or a second AV to the location to capture at least a second channel sounding measurement record. The processing system may then obtain from the first AV or the second AV the at least the second channel sounding measurement record, and may adjust at least one aspect of the cellular network in response.

Abstract: Facilitating radio access network on-demand dynamic bandwidth allocation in advanced networks is provided herein. Operations of a system include determining that a group of network slice resources associated with network equipment fail to satisfy a specification applicable to a user equipment. The operations can also include extracting a first group of resource blocks from a first network slice resource of the group of network slice resources. Further, the operations can include reallocating the first group of resource blocks to a second network slice resource of the group of network slice resources. A combination of the first group of resource blocks and a second group of resource blocks of the second network slice resource is determined to satisfy the specification applicable to the user equipment.
