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.

Abstract: A method for routing in a quantum network is provided. The method may include receiving parameters including a fidelity with coherence decay time and an entanglement generation rate for each quantum node in a mesh quantum network by a controller, the controller being configured to communicate with each quantum node of a plurality of quantum nodes in the mesh quantum network. Each quantum node includes a quantum memory and a processor. The method may also include analyzing the fidelity with coherence decay time and the entanglement generation rate to yield a determination of a path fidelity with a path coherence decay time and a path entanglement generation rate between at least one pair of quantum nodes. The method may further include, based on the determination, selecting a quantum communication path from a source node to a destination node.

Abstract: Correlating devices and clients across addresses may be provided. A first address associated with a client device may be received. When the client device is not connected to a network, first location data associated with the first address may be obtained using a passive technique. A second address and second location data associated with the second address may then be obtained using an active technique. It may then be determined that the first location data and the second location data correlate. In response to determining that the first location data and the second location data correlate, it may be determined that the client device has changed from the first address to the second address.

Abstract: Presented herein are techniques to facilitate extending a multiple access Protocol Data Unit (PDU) session and Access Traffic Steering, Switching, and Splitting Low-Layer (ATSSS-LL) policies to an enterprise network. In one example, a method may include obtaining a request for an ATSSS-LL policy for a user equipment (UE) for establishing a multiple access protocol data unit session for the UE via a wireless wide area access network for an enterprise network; and providing to the UE one or more ATSSS-LL rules for the ATSSS-LL policy, an Internet Protocol (IP) address for the multiple access protocol data unit session for the UE, and an identifier for the multiple access protocol data unit session for the UE in which the IP address is utilized for a wireless local area access network connection for the UE established via a wireless local area access network of the enterprise network.

Abstract: Techniques are described to provide traffic steering and policy combining in a mobile network. In one example, a method includes combining, by a policy function of a network, a user equipment (UE) access policy comprising UE access rules obtained from a UE with a network-based access policy associated with the network to generate a combined access policy, the combined access policy comprising combined access rules; communicating the combined access rules to the UE via a message, wherein the message comprises an indication that indicates that the UE is not allowed to override the combined access rules with the UE access rules; and communicating the combined access rules to a user plane function handling traffic for the UE.

Abstract: Techniques are described for integrating cellular access within an enterprise fabric. In one example, a method includes obtaining, by a cellular termination function via a cellular access point, a request from a client for data plane connectivity via a network, wherein the cellular access point is registered within the network and is in communication with a first switch of the network; obtaining, by the cellular termination function, cellular policy information and enterprise policy information for the client; obtaining, by the cellular termination function, an Internet Protocol (IP) address for the client; and establishing data plane connectivity for the client with the network via the cellular access point, the first switch of the network, and a second switch of the network based, at least in part, on the IP address for the client, wherein the second switch connects the network with one or more data networks.

Abstract: In one example, a control plane entity obtains an indication that a User Equipment (UE) has entered an idle mode. The control plane entity sets a routing locator corresponding to the UE to cause the control plane entity to trigger a paging request toward the UE to prompt the UE to transition from the idle mode when a first network node obtains a downlink packet destined for the UE. The control plane entity obtains a notification that the first network node has obtained the downlink packet and initiates the paging request toward the UE. The control plane entity updates the routing locator corresponding to the UE to cause the first network node to transmit further downlink packets destined for the UE toward a second network node configured to handle traffic on behalf of the UE.

Abstract: Techniques are described to provide to provide service allocation across multi-managed heterogeneous networks. In one example, a method includes determining, by an application network policy controller, service information for an application, wherein the application communicates with an application server. The method may further include identifying one or more network domains of a plurality of network domains to provide network connectivity between the application and the application server based, at least in part, on service qualifiers and context information for the plurality of network domains and the service information for the application; generating an application policy for the application, wherein the application policy identifies, at least in part, the one or more network domains to provide network connectivity between the application and the application server; and communicating the application policy to the one or more identified network domains to provide network connectivity between the application and the application server.
