Abstract: In one embodiment, a device in a network receives an attack mitigation request regarding traffic in the network. The device causes an assessment of the traffic, in response to the attack mitigation request. The device determines that an attack detector associated with the attack mitigation request incorrectly assessed the traffic, based on the assessment of the traffic. The device causes an update to an attack detection model of the attack detector, in response to determining that the attack detector incorrectly assessed the traffic.

Abstract: A wireless device can achieve higher predictability for its transmissions by inserting a placeholder frame in a transmission queue before RoCE data has been received. In addition, a contention countdown associated with the placeholder frame can start before the RoCE data is ready for transmission. Once the RoCE data is available, the device can insert the data into the payload of the placeholder frame, thereby reducing the wait time before the RoCE data can be transmitted wirelessly. Additionally, the device can improve reliability by transmitting RoCE data using multiple subcarrier RUs in a channel. The data blocks and the duplicative data can be transmitted in parallel using the subcarrier RUs. If a subset of the subcarrier RUs are blocked because of narrowband interference, the receiving device can nonetheless recover the data blocks and reconstruct the RoCe packet from the data transported on the RUs that did not have interference.

Abstract: A Hypervisor hosted on a computer device includes a Fibre Channel (FC) port to communicate with an FC switch in an FC switched fabric. The FC port has a port identifier assigned by the switch device. The Hypervisor solicits from the switch FC priority values available to be allocated as respective local identifiers of virtual machines (VMs). The Hypervisor instantiates a VM with a global VM identifier, and allocates one of the solicited priority values to the instantiated VM such that the allocated priority value and the port identifier together represent a fabric VM identifier. After the allocating, the Hypervisor sends to the FC switch an update frame to indicate the instantiated VM, the global VM identifier, and the fabric VM identifier. During an FC session, the Hypervisor exchanges FC frames with an FC destination port connected to the switched fabric. Each session frame indicates the fabric VM identifier.

Abstract: In one embodiment, a computing device provides a feature vector as input to a random decision forest comprising a plurality of decision trees trained using a training dataset, each decision tree being configured to output a classification label prediction for the input feature vector. For each of the decision trees, the computing device determines a conditional probability of the decision tree based on a true classification label and the classification label prediction from the decision tree for the input feature vector. The computing device generates weightings for the classification label predictions from the decision trees based on the determined conditional probabilities. The computing device applies a final classification label to the feature vector based on the weightings for the classification label predictions from the decision trees.

Abstract: In one embodiment, a device receives data regarding usage of access points in a network by a plurality of clients in the network. The device maintains an access point graph that represents the access points in the network as vertices of the access point graph. The device generates, for each of the plurality of clients, client trajectories as trajectory subgraphs of the access point graph. A particular client trajectory for a particular client comprises a set of edges between a subset of the vertices of the access point graph and represents transitions between access points in the network performed by the particular client. The device identifies a transition pattern from the client trajectories by deconstructing the trajectory subgraphs. The device uses the identified transition pattern to effect a configuration change in the network.

Abstract: A first endpoint device has access to common video data including common video frames and encoded common video data having the common video frames encoded therein. The encoded common video data is downloaded to a second endpoint device. After, or during, the downloading of the encoded common video data, live video frames are played in a play order. The live video frames are encoded in the play order into encoded live video frames. To encode the live video frames, each live video frame is predicted based on a previous live video frame that has been encoded and a common video frame from the common video data that has been downloaded in the encoded common video data. The encoded live video frames include indications of the previous live video frame and the common video frame used to encode each encoded live video frame are transmitted to the second endpoint device.

Abstract: First, an authentication module may receive an identification (ID) linking request, create a secured ID linking request from the ID linking request, and send the secured ID linking request to a packet gateway module located in a packet core of a mobile network. Next, the packet gateway module may insert into the secured ID linking request, an encrypted version of a mobile identifier corresponding to a client device from which the secured ID linking request was received. Next, a mobile video session manager module may receive from the packet gateway module, the secured ID linking request and link a subscriber of a managed video service corresponding to a video identifier to the client device corresponding to the mobile identifier. A policy corresponding to the subscriber of the managed video service may then be applied to flows over the packet core to and from the client device.

Abstract: Techniques for generating a prediction for a location of a mobile device includes a network controller obtaining signal strength information and angle-of-arrival information for mobile devices from a plurality of access points disposed at a location that includes two or more zones. The network controller extracts features from the obtained information. The features indicate whether the mobile devices are more likely in a first zone than in one or more of second zones of the two or more zones.

The network controller uses the software model to generate a prediction indicating that a first mobile device is in one of the two or more zones, and performs an action at the location based on the prediction.

Abstract: In one embodiment, a load-balancer in a computer network receives an end-device request for a particular network-based resource, and determines a popularity of the particular network-based resource being requested in comparison to other network-based resources requested by end devices in the computer network. In response to the particular network-based resource being popularly requested, the load-balancer forwards the end-device request into a Fog network to cause the Fog network to respond to the end-device request with particular network-based resource. Conversely, in response to the particular network-based resource not being popularly requested, the load-balancer forwards the end-device request into a Cloud network to cause the Cloud network to respond to the end-device request with particular network-based resource.

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.
