Exemplary embodiments include methods and/or procedures for handling messages from one or more data-plane nodes (DPNs) to a plurality of controller nodes configured in a cluster, comprising: receiving a message from a DPN; tagging the message with an incarnation identifier (IID) associated with the DPN; and performing HD handling of the tagged message, which includes comparing a value of the IID of the tagged message with a value of a global IID associated with the DPN, discarding the tagged message if the value of the IID of the tagged message is less than the value of the global IID, and processing the tagged message if the value of the IID of the tagged message is not less than the value of the global IID. Exemplary embodiments also include controller nodes, controller clusters, and computer-readable media embodying operations of the exemplary methods and/or procedures.

A method is disclosed for out-of-band data communication with a base station in a wireless network, the method comprising: determining, at a base station in a cellular access network, the base station configured to use a coordination server and to a first core network for providing network access to user equipments (UEs), an occurrence of an event regarding a communication problem related to the base station; sending an out-of-band message, via an embedded UE module coupled to the base station attached to a second core network, to the coordination server, based on the occurrence of the event at the base station; updating, at the coordination server, a stored status for the base station, thereby enabling a status of the base station to be updated at the coordination server via an out-of-band message.

A mechanism is disclosed operating a transport network function (TNF) as part of a fifth generation wireless (5G) virtualized control plane. The mechanism includes receiving a request to compute a traffic engineering (TE) path in a 5G transport network for a packet data unit (PDU) session, the request received from a 5G virtualized control plane function via a service based interface (SBI) bus. Network topology information for the 5G transport network is obtained via a northbound interface (Nn). A TE path across the 5G transport network is computed for the PDU session based on the network topology information. A TE path identifier for the TE path computed for the PDU session is returned via the SBI bus.

A method of deploying a network service across a plurality of data centers, includes the steps of: in response to a request for or relating to a network service, identifying virtual network functions associated with the network service and determining network connectivity requirements of the virtual network functions, issuing commands to provision a first virtual link between at least two of the data centers in which the virtual network functions are to be deployed, and issuing commands to provision a second virtual link to one of the data centers in which the virtual network functions are to be deployed.

Described herein are systems and methods for fault tolerance in a network cloud environment. In accordance with various embodiments, the present disclosure provides an improved fault tolerance solution, and improvement in the fault tolerance of systems, by way of failure prediction, or prediction of when an underlying infrastructure will fail, and using the predictions to counteract the failure by spinning up or otherwise providing new component pieces to compensate for the failure.

Techniques are described for enabling users of a cloud provider network to define and use custom “virtual regions” comprised of selected sets of cloud provider network infrastructure locations. A cloud provider network enables users to obtain information about available infrastructure locations and to identify locations that satisfy a set of performance characteristics and other parameters. Once a set of desirable infrastructure locations have been identified, users can request the creation of a virtual region to be associated with their user account, where the request specifies a set of infrastructure locations to comprise the virtual region. Once a virtual region is created, users can cause computing resources to be launched into or otherwise associated with the virtual region in a manner similar to the use of existing regions and availability zones.

Provided are a network operation method and apparatus, a device, and a storage medium. The network operation method includes that a management node receives virtualized network function information carrying at least one dynamic network change flag, where the at least one dynamic network change flag is used for indicating whether a dynamic network change is supported; and that the management node operates on a first-type network according to the virtualized network function information.

A computer implemented method includes granting a tenant administrator client machine access to a cloud hosted tenant service joined to a directory service. A bulk token for the tenant is obtained in response to a request received from the tenant administrator client machine. An identifier of an authorized tenant client to the cloud hosted tenant service is received and results in the provisioning of a tenant client virtual machine in a cloud service for the authorized tenant client in accordance with a specified provisioning package associated with the bulk token. The tenant client virtual machine is then joined to the directory service. On receipt of an authorized client token at the cloud hosted tenant service from a tenant client machine, the tenant client machine is provided a connection to the tenant client virtual machine.

A computer implemented method includes granting a subscriber client access to a cloud service-based resource group within a subscriber controlled computing environment. The subscriber controlled computing environment has a virtual network. A direct network connection is established via the virtual network to a domain controller in the subscriber controlled computing environment. The virtual network is extended to a subscriber client virtual machine in a producer cloud service. The subscriber client virtual machine is then joined with the virtual network. Access to the subscriber client virtual machine is provided via the subscriber controlled computing environment and virtual network.

Described are examples for providing management of a virtual wide area network (vWAN) based on operator policies. A network orchestrator presents, to a network operator, a representation of the vWAN including virtual network entities associated with respective geographic locations and virtual connections between the virtual network entities. The network orchestrator receives a policy for the virtual wide area network from the network operator via the representation, the policy to be implemented at one or more of the virtual connections. The network orchestrator translates the policy for the virtual wide area network into a configuration of an underlying wide area network (WAN). The underlying WAN a plurality of geographically distributed physical computing resources in geographic regions corresponding to the virtual network entities and connections there between.
