Abstract: This disclosure describes techniques for monitoring expected behavior of devices in a computing network. Behavior of network devices may include performing various functions associated with transferring data packets through the computing network. Monitoring expected behavior may include sending a probe packet into the computing network, and determining whether network devices behave as expected with respect to the probe packet. In some examples, behaviors such as replicating, forwarding, eliminating, ordering, and/or other functions regarding data packets may be validated using the present techniques. As computing networks and/or operations become more complex, assuring the expected behavior of network devices may become more important for the continued efficient, smooth, successful, and/or timely flow of data traffic.

Abstract: The present disclosure is directed to BIER forwarding over varying BSL domains, the methods including the steps of receiving, at a border node, a packet comprising a BIER header having a BIER bit string with a first bit string length; reading an incoming label of the packet comprising instructions to split the BIER header into a plurality of smaller headers associated with a plurality of smaller bit strings; generating a set of split bit masks; performing a separate bitwise AND operation on each split bit mask and the BIER bit string to generate the plurality of smaller bit strings, each copied to a corresponding smaller header of the plurality of smaller headers; and performing a lookup for each of the plurality of smaller headers on a respective forwarding table to determine one or more egress routers to which to transmit the packet.

Abstract: Systems, methods, and computer-readable media for context-based transfer and access of data include a producer which receives a request from a consumer to access a data block. The producer verifies whether a context associated with the consumer will allow access the data block, by providing a challenge to the consumer and obtaining a response, the response including a certification that the context associated with the consumer will allow the consumer to access the data block. Upon verifying that the context allows the consumer to access the data block, the producer transfers a data capsule, the data capsule including an encrypted version of the data block and a micro agent for monitoring access to the data block. The micro agent can interact with an operating system at the consumer to allow decryption and local access of the data block upon the data capsule being transferred.

Abstract: Failure prediction signaling and cognitive user migration may be provided. A client device may receive at least a portion of failure prediction data. The client device may then analyze the at least the portion of the failure prediction data. The client device may then roam from a first computing device to a second computing device in response to analyzing the at least the portion of the failure prediction data.

Abstract: In one embodiment, an access policy enforcement service receives a user authentication request from an end-user device. The access policy enforcement service identifies a telemetry collection intent from the user authentication request. The access policy enforcement service determines a monitoring policy based on the telemetry collection intent identified from the user authentication request. The access policy enforcement service configures, according to the monitoring policy, one or more telemetry collection agents to collect telemetry for traffic associated with the end-user device.

Abstract: Systems, methods, and computer-readable for multi-spatial scale object detection include generating one or more object trackers for tracking at least one object detected from on one or more images. One or more blobs are generated for the at least one object based on tracking motion associated with the at least one object. One or more tracklets are generated for the at least one object based on associating the one or more object trackers and the one or more blobs, the one or more tracklets including one or more scales of object tracking data for the at least one object. One or more uncertainty metrics are generated using the one or more object trackers and an embedding of the one or more tracklets. A training module for detecting and tracking the at least one object using the embedding and the one or more uncertainty metrics is generated using deep learning techniques.

Abstract: A method of orchestrating one or more radio resources among various services executing within a container. The method includes obtaining, by an orchestration engine executing on a network device, a request, from a first service of a plurality of services, for use of a physical/hardware resource that connects a container running on the network device to a network. The request from the first service has a particular priority. The plurality of services execute within the container. The method further includes determining whether to connect the first service to the network via the physical/hardware resource based on the priority and an availability status of the physical/hardware resource and establishing, at a kernel level, a connection between the first service and the physical/hardware resource based on the determining.
