Abstract: In one embodiment, a device configures a plurality of subinterfaces for each of a plurality of physical ports of a software defined network (SDN). The device allocates a fixed amount of bandwidth to each of the subinterfaces. The device forms a plurality of midlays for the SDN by assigning subsets of the plurality of subinterfaces to each of the midlays. The device assigns a network slice to one or more of the midlays, based on a bandwidth requirement of the network slice.

Abstract: In one embodiment, a method comprises: receiving, by a switching device in a deterministic network, a first data packet associated with an identified flow of data packets, and queuing the first data packet for deterministic transmission at a deterministic transmit instance to a next-hop device in the deterministic network; detecting, by the switching device, reception of a newest data packet associated with the identified flow and before the deterministic transmission of the first data packet; and prioritizing for the identified flow, by the switching device, the newest data packet based on deterministically transmitting, at the deterministic transmit instance, the newest data packet instead of the first data packet.

Abstract: In one embodiment, a service receives a feature availability report indicative of which telemetry variables are available at a device in a network and resource costs associated with data features that the device could compute from the telemetry variables. The service selects at least a subset of the data features for input to a machine learning model, based on their associated resource costs and on their respective impacts on one or more performance metrics for the machine learning model. The service trains the machine learning model to evaluate the selected data features. The service sends the trained machine learning model to the device. The device computes the selected data features from the telemetry variables available at the device and uses the computed data features as input to the machine learning model.

Abstract: In one embodiment, a method comprises: storing, by a computing device in a non-deterministic data network, a plurality of data packets originated by a source device into a mass storage medium associated with the computing device; receiving, by the computing device, a data request originated by an access point device providing deterministic reachability to a deterministic device in a deterministic data network providing reachability to multiple deterministic devices, the request specifying one or more deterministic constraints associated with reaching the deterministic device; and supplying, by the computing device, a selected one of the data packets to the access point device for delivery of data stored therein to the deterministic device according to the one or more deterministic constraints.

Abstract: In one embodiment, a supervisory device for a software defined networking (SDN) fabric predicts characteristics of a new traffic flow to be admitted to the fabric, based on a set of initial packets of the flow. The supervisory device predicts an impact of admitting the flow to the SDN fabric, using a heatmap-based saturation model for the SDN fabric. The supervisory device admits the flow to the SDN fabric, based on the predicted impact. The supervisory device uses reinforcement learning to adjust one or more call admission control (CAC) parameters of the SDN fabric, based on captured telemetry data regarding the admitted flow.

Abstract: In one embodiment, a method comprises receiving, by a transport layer executed by a processor circuit in an apparatus, an identifiable grouping of data; storing, by the transport layer, the data as transport layer packets in a buffer circuit in the apparatus, the storing including inserting into each transport layer packet a grouping identifier that identifies the transport layer packets as belonging to the identifiable grouping; and causing, by the transport layer, a plurality of transmitting deterministic network interface circuits to deterministically retrieve the transport layer packets from the buffer circuit for deterministic transmission across respective deterministic links, the grouping identifier enabling receiving deterministic network interface circuits to group the received transport layer packets, regardless of deterministic link, into a single processing group for a next receiving transport layer.

Abstract: In one embodiment, a method comprises causing, by an apparatus, establishment of first and second multicast trees within one or more underlay switching fabrics of one or more fat tree topologies, the first and second multicast trees comprising first and second multicast roots for multicast transmission to leaf network devices in the respective first and second multicast trees; causing, by the apparatus, establishment of an overlay tunnel between the first and second multicast roots, the overlay tunnel independent and distinct from the first and second multicast trees; causing the first multicast root to multicast transmit, via the first multicast tree, a data packet having been transmitted to the first multicast root; and causing the first multicast root to unicast transmit the data packet to the second multicast root via the overlay tunnel, for multicast transmission of the data packet by the second multicast root via the second multicast tree.

Abstract: In one embodiment, a supervisory service receives a registration message broadcast by a first vehicle and captured by a RSU in the network of RSUs. The supervisory service registers the first vehicle by validating a signature of the registration message without registering a media access control (MAC) address of the first vehicle and without causing to send a registration response to the first vehicle. The supervisory service receives a message broadcast by a second vehicle addressed to the first vehicle and captured by at least one RSU in the network of RSUs. The supervisory service selects one or more RSUs in the network of RSUs to re-broadcast the message. The supervisory service controls the one or more RSUs to re-broadcast the message.

Abstract: In one embodiment, a first actuator in a network of sensors and actuators executes a walker agent configured to adjust an actuation setting of the first actuator. The actuation setting controls an area of coverage of the first actuator when actuated. The executing agent on the first actuator receives one or more sensor measurements from one or more of the sensors that are in communication range of the first actuator. The executing agent also controls, based on the received one or more sensor measurements, the area of coverage of the first actuator by adjusting its actuation setting, in an attempt to optimize coverage of the sensors in the network by the areas of coverage of the actuators. The first actuator unloads the executing walker agent after adjusting the actuation setting of the first actuator and propagates the agent to another one of the actuators in the network for execution.

Abstract: In one embodiment, a device in a network receives a query walker agent configured to query information from a distributed set of devices in the network based on a query. The device executes the query walker agent to identify the query. The device updates state information of the executing query walker agent using local information from the device and based on the query. The device unloads the executing query walker agent after updating the state information. The device propagates the query walker agent with the updated state information to one or more of the distributed set of devices in the network, when the updated state information does not fully answer the query.
