The disclosure relates to a method, executed by an NFV-MANO, for providing a requested Service Availability Level (SAL) for a Network Service (NS). The method comprises at each of a plurality of layers of the NFV-MANO, mapping the requested SAL to a SAL that needs to be provided by a lower layer of the NFV-MANO. The method comprises propagating the mapped requested SAL through interfaces between layers of the NFV-MANO, from an NFVO towards a VIM. The method comprises receiving an estimated SAL′ for the NS based on virtual resources (VR) allocated by the VIM for satisfying the requested SAL. The method comprises, upon determining that the estimated SAL′ does not satisfy the requested SAL, taking actions to meet the requested SAL, or upon determining that the estimated SAL′ satisfies the requested SAL taking no further actions.

Improving wireless service subscriber experiences by dynamically managing wireless communication resources using a big data analytic mechanism is presented herein. A method can include receiving, by a system comprising a processor via a software-based interface of a control plane of a communication network, service data corresponding to a request for a wireless communication service; receiving, by the system via the software-based interface of the control plane, contextual data corresponding to a subscription of the wireless communication service; receiving, by the system via the software-based interface of the control plane, network data corresponding to data packet transmissions of a network device within a data plane of the communication network; and configuring, by the system via the software-based interface of the control plane based on a defined set of policies, the service data, the contextual data, and the network data, a resource of the data plane corresponding to the wireless communication service.

Systems, methods, and computer-readable media for on-demand security provisioning using whitelist and blacklist rules. In some examples, a system in a network including a plurality of pods can configure security policies for a first endpoint group (EPG) in a first pod, the security policies including blacklist and whitelist rules defining traffic security enforcement rules for communications between the first EPG and a second EPG in a second pods in the network. The system can assign respective implicit priorities to the one or more security policies based on a respective specificity of each policy, wherein more specific policies are assigned higher priorities than less specific policies. The system can respond to a detected move of a virtual machine associated with the first EPG to a second pod in the network by dynamically provisioning security policies for the first EPG in the second pod and removing security policies from the first pod.

This disclosure describes techniques for configuring and managing scalable global private networks associated with a service provider. Different input mechanisms, such as an API, a UI, or a CLI may be utilized to configure, and manage a global private network that spans across the cloud in different geographic locations and connects to different stand-alone networks. The user may proactively use the input mechanisms to configure and query different network resources to reactively configure settings for reacting to one or more events. The input mechanisms may also be utilized to define the network resources to be modeled within the global private network as well as connections within the global network. A user may configure events/metrics to be monitored, tasks/workflows to be performed, and the like. In some configurations, a network management service (NMS) may perform health monitoring and reachability monitoring to identify possible issues in the global network.

Network management techniques are described. A controller device of this disclosure manages a device group of a network. The controller device includes processing circuitry in communication with the memory, the processing circuitry being configured to receive, using a programmable diagnosis service executed by the processing circuitry, a programming input, to form, using the programmable diagnosis service, based on the programming input, a resource definition graph that models interdependencies between a plurality of resources supported by the device group, to detect, using the programmable diagnosis service, an event affecting a first resource of the plurality of resources, and to identify, using the programmable diagnosis service, based on the interdependencies modeled in the resource definition graph formed based on the programming input, a root cause event that caused the event affecting the first resource, the root cause event occurring at a second resource of the plurality of resources.

Certain aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for a UE to measure sounding reference signal (SRS) transmission from another UE. The measurements results may be used, for example, by a serving cell for interference mitigation purposes. For example, the disclosed techniques may include a first UE receiving a configuration for measuring SRS transmitted by a second UE; determining a first bandwidth part (BWP) associated with the configuration; determining a frequency reference point for the SRS to be measured; determining SRS measurement resources, based on one or more parameters of the configuration and the frequency reference point; and measuring SRS transmitted by the second UE on the determined SRS measurement resources.

A method for establishing message priority in network slices based on quality of service (QoS) parameters includes receiving, by a network slice configuration service provider entity and from a network slice management service provider entity, a network slice creation notification message containing at least a QoS profile corresponding to a created network slice, utilizing the QoS profile to derive a service based interface (SBI) message priority (SMP) associated with the network slice, and providing the SMP to a requesting access and mobility management function (AMF) entity in response to receiving a network slice selection request message from the AMF entity, wherein the AMF entity assigns the SMP level value to network traffic directed to the network slice.

System, methods, and computer-readable media for validating and committing a shared O-RU configuration via a shared O-RU Operator. The shared O-RU Operator validates a partitioned configuration received from a tenant operator, with the ability to indicate to the tenant operator that the partitioned configuration is conformant to agreed-upon sharing rules and then commits the shared configuration to the shared O-RU. The shared O-RU operator shares the outcome of the commit operation to the tenant operator via defined operational-data that can be read by the tenant operator. A single radio in O-RAN is shared by multiple different operators and enables a neutral host to deploy a radio unit and then have that attached to different operators networks.

A method, system, and computer program product for open flow connection between differing software-defined network controllers are provided. The method generates a networking interface between a first networking controller and a second networking controller. Networking information is exchanged between the first networking controller and the second networking controller using the networking interface. A logical switch is generated between the first networking controller and the second networking controller by matching at least a portion of the networking information of the second networking controller at the first networking controller. The method exchanges the matched portion of the networking information from the first networking controller with the second networking controller to create layer two open flow connection between the first networking controller and the second networking controller.
