Abstract: In one example embodiment, one or more machine learning models of at least one processor determine an agent of a communication center to receive a communication from a user according to one or more objectives that optimize a corresponding metric from interaction of the user and the agent. Features for training the one or more machine learning models are dynamically selected based on relevance of the features to attaining the one or more objectives. The at least one processor routes the communication to the agent of the communication center.

Abstract: A system and method are provided for communicating security service context within a network. Intermediary nodes located along the path of a data flow apply various security services to the data flow, and keep a record of the security services by generating in-band and out-of-band information. The in-band information is limited, e.g., by the maximum transmission unit (MTU) to short attestations that fit within optional IPv6 extension headers. The out-of-bound information, which is recorded, e.g., in a ledger using an overlay network, provides additional information fully describing the security services. Based on the in-band and out-of-band information (e.g., using the attestations to retrieve the additional information from the ledger), the data flow is either allowed or denied entrance to a particular workload. Applying the security services and generating the in-band and out-of-band information can be performed using data processing units (DPUs) and/or an extended Berkley packet filters (eBPFs).

Abstract: A system and method are provided for adding in-band metadata with a data flow. The in-band metadata can be based on observations by an extended Berkley packet filter (eBPF) of an application running in a datacenter, for example. A processor executes the application to generate data that is encoded in the payloads of packets in a data flow to be transmitted via a network to a destination. The eBPF is also executed on the processor and generates observations of the application (e.g., OSI layer 7 observations). Metadata is generated based on the observations and encoded into headers of the packets of the data flow. The metadata can then be used at the destination to determine the next processing steps for the data flow (e.g., is the data flow trusted and allowed into another workload).

Abstract: In one embodiment, a device obtains quality of experience metrics for an online application whose traffic traverses a particular interface of a router located at a first site in a network. The device identifies a correlation between throughput of the particular interface and the quality of experience metrics for the online application. The device makes a determination that the correlation is a root cause of degradation of the quality of experience metrics for the online application at least in part by determining whether throughput of an interface of a remote router located at a second site in the network is correlated with the quality of experience metrics. The device configures, based on the determination, a priority queue associated with the particular interface for use by traffic of the online application.

Abstract: A method comprises: receiving a query on a topic from a user associated with user attributes indicative of a user comprehension level on the topic; providing the query to an AI model; receiving from the AI model a response to the query that has a response comprehension level on the topic that is less than the user comprehension level; iteratively adding, to the query, topically-relevant user attributes of the user attributes to produce iterative queries that increase in technical detail on the topic; providing the iterative queries to the AI model; responsive to providing the iterative queries, receiving, from the AI model, iterative responses that increase in technical detail on the topic and have response comprehension levels that increase on the topic; and determining, among the iterative responses, a final response having a response comprehension level that most nearly matches the user comprehension level.

Abstract: A mobile network is operative to perform a quota validation procedure in relation to a maximum number of user equipments (UEs) permitted in a network slice. In one illustrative example, a control plane (CP) function of the mobile network may receive, from the UE, a message which indicates a registration request for registration and includes a slice ID of the network slice. The CP function may manage a registration procedure for assigning resources of the network slice to the UE. The CP function may alternatively manage the registration procedure to refrain from assigning the resources of the network slice to the UE, at least for a delay time period, based on identifying that an indication of the UE indicates an expected delay in use of service in the network slice. The indication may be included in the message and indicate the delay time period of the expected delay.
