Abstract: An enterprise controller of an enterprise network sends to a service gateway of a service provider network a request for network slice information about network slices provisioned on a data plane of the service provider network. Responsive to the sending, the enterprise controller receives from the service gateway the network slice information including identifiers of and properties associated with the network slices. Responsive to receiving a request for the network slice information from a network device at a border of a forwarding plane of the enterprise network, the enterprise controller sends the network slice information to the network device to cause the network device to perform configuring network traffic in the forwarding plane with identifiers of ones of the network slices that match the network traffic, and to perform forwarding the network traffic configured with the identifiers to the data plane of the service provider network.

Abstract: In one illustrative example, an interface between a user plane function (UPF) instance of a mobile network and a tunnel router endpoint of an enterprise software-defined wide area network (SD-WAN) fabric is provided. The UPF instance may be part of a network slice that is (uniquely) associated with an enterprise of the enterprise SD-WAN. A plurality of mappings between policies associated with different QoS flows via the UPF instance and SD-WAN policies associated with different virtual private networks (VPNs) of the SD-WAN fabric may be maintained. Each VPN of the SD-WAN fabric may be associated with a different underlying transport mechanism that satisfies characteristics of a specific SD-WAN policy. Communications for user equipment (UE) in the mobile network may be facilitated across the SD-WAN fabric based on the policy mappings.

Abstract: A method, computer system, and computer program product are provided for providing traceability and observability for decentralized applications. A plurality of transaction metadata records are obtained corresponding to a plurality of transactions related to execution of a computing task by a decentralized application, wherein each transaction metadata record includes a same operation record that identifies the computing task, and an actor identifier that indicates an identity of an entity involved in a particular transaction of the plurality of transactions. A longitudinal history of the execution of the computing task is generated that identifies the entity involved in each transaction based on the plurality of transaction metadata records. An operational state of one or more entities is determined based on comparing the longitudinal history of the execution of the computing task to data relating to a different computing task.

Abstract: Presented herein are techniques for verifying data. A method can include obtaining, from an oracle, a first data set associated with a distributed ledger. The method further includes obtaining a plurality of data sets from a plurality of sources. The method further includes generating a confidence level regarding the first data set for validating the first data set, based on comparing the first data set to the plurality of data sets. The method further includes storing the first data set in the distributed ledger based on the confidence level indicating that the plurality of data sets concurs with the first data set. The method further includes taking a remedial action without storing the first data set in the distributed ledger based on the confidence level indicating a discrepancy between the plurality of data sets and the first data set.

Abstract: Presented herein are techniques to facilitate fast roaming between a mobile network operator-public (MNO-public) wireless wide area (WWA) access network and an enterprise private WWA access network. In one example, a method is provided that may include generating, by an authentication node, authentication material for a user equipment (UE) based on the UE being connected to a public WWA access network, wherein the public WWA access network is associated with a mobile network operator, and the authentication node and the UE are associated with an enterprise entity; obtaining, by the authentication node, an indication that the UE is attempting to access a private WWA access network associated with the enterprise entity; and providing, by the authentication node, the authentication material for the UE, wherein the authentication material facilitates connection establishment between the UE and the private WWA access network.
