Abstract: Maintaining distributed references to data stored on devices of a computer network is described. For instance, a system includes a request component that can communicate a removal request to network equipment to remove a resource from storage by first storage equipment. The system can further include an indicator component that can receive, from the network equipment, a first indication that the removal request did not cause removal of the resource. The removal request can be determined not to have caused the network equipment to remove the resource based on index information of a resource index, which could have identified that the resource was referenced by a resource stub stored on second storage equipment.

Abstract: A system comprises one or more observation stations. Each observation station of the one or more observation stations comprises a corresponding set of one or more sensors. Additionally, the system comprises one or more physical machines that implement a computation engine configured to receive first observation data from the one or more observation stations. The computation engine may use the first observation data to train a machine learning system. The computation engine may subsequently use the trained machine learning system to provide feedback regarding an additional instance of the observation subject. The computation engine outputs the feedback.

Abstract: The invention relates to a computer-implemented method, a corresponding a computer program product and a corresponding apparatus for distributing cached content in a network, the computer-implemented method comprising: collecting statistics regarding requests made and paths taken by the requests from source nodes to server nodes via intermediate nodes, the source nodes, intermediate nodes, and server nodes interconnected by edges having queues with respective queue sizes associated therewith, the requests including indications of content items to be retrieved; storing the content items at the server nodes; caching, by the intermediate nodes, the content items up to a caching capacity; and performing caching decisions that determine which of the content items are to be cached at which of the intermediate nodes, based upon costs that are monotonic, non-decreasing functions of the sizes of the queues.

Abstract: A method for updating a non-current data model using a current data model. The update exports a first data set which includes a file with a model object for the current data model, another with option group (“OG”) objects, another with rule objects, and another with junction objects that relate a rule to an OG. The update exports a second data set that includes a file with model-to-OG junction objects, and a file with model-to-rule junction objects. The update transports the first, and second data sets from a first data repository to a second data repository. The update imports, to the non-current data model, the first, and second data sets. The update recreates, in the non-current data model, the model-to-option-group junctions and the model-to-rule junctions.

A group may include one or more representations of content. The metadata may include a group element, and the group element may provide a summary of attributes of one or more representations included in the group.

The operations include determining that a mobile device is able to receive data from the monitoring system; and providing, to the mobile device, data indicating the first event and an instruction to transmit the data indicating the first event to a server upon the mobile device being able to communicate with the outside network.

Abstract: Systems and methods for autonomous program management include a device which may transmit data to a client in response to a first request from the client. The data may include a response to the first request and a copy of data available to the device corresponding to the first request or the client. The device may receive a second request including the copy of data from the client. The device may determine that the second request is from an autonomous program rather than a user of the client based on the copy of data from the second request. The device may block at least one subsequent request from the client in response to the determination that the second request is from an autonomous program.

Abstract: A computer-implemented method for domain analysis comprises: obtaining, by a computing device, a domain; and inputting, by the computing device, the obtained domain to a trained detection model to determine if the obtained domain was generated by one or more domain generation algorithms. The detection model comprises a neural network model, a n-gram-based machine learning model, and an ensemble layer. Inputting the obtained domain to the detection model comprises inputting the obtained domain to each of the neural network model and the n-gram-based machine learning model. The neural network model and the n-gram-based machine learning model both output to the ensemble layer. The ensemble layer outputs a probability that the obtained domain was generated by the domain generation algorithms.

Abstract: In response to receiving an ASR message, a VTEP generates a specially modified control plane message advertising the IP-to-MAC binding of the ASR message. The control plane message may be modified to indicate that it is not to be used for MAC learning. The control plane message is advertised over the network. When an intended recipient receives the message, it uses that message just for the IP-to-MAC binding. When an unintended recipient receives the message, it may drop it as invalid.

Abstract: An image-based prediction service of a provider network may receive multivariate time series data (e.g., from different sensors for a machine) from a remote network of the client. The multivariate time series data includes different time series of data that are obtained from different data sources (e.g., sensors) over a time period. The image-based prediction service may transform the multivariate time series data into image data that represents an image. The image-based prediction service may then process the image data using one or more image processing models to generate a prediction (e.g., machine failure within a week). The image-based prediction service may send the prediction to the remote network.

Abstract: A server apparatus transmits information including a hash value of a previous block, data of a current block, and a search range with regard to one blockchain system to a client apparatus in a mining pool. The client apparatus calculates a Nonce value based on the information transmitted from the server apparatus and transmits the calculated Nonce value to the server apparatus. The server apparatus can transmit information regarding a plurality of blockchain systems to the client apparatus. The server apparatus decides one blockchain system based on a predetermined condition, transmits information related to the decided blockchain system to the client apparatus, and causes the client apparatus to perform mining.

Abstract: The present disclosure is directed to associating computing devices with each other based on computer network activity for selection of content items as part of an online content item placement campaign. A first linking factor is identified based on a connection between a first device and the computer network via a first IP address during a first time period, and based on a connection between a second device and the computer network via the first IP address during the first time period. A number of devices that connect with the computer network via the first IP address is determined. A positive match probability is generated. A second and third linking factors are monitored. A negative match probability is determined based on the second and third linking factors. The first device is linked with the second device based on the positive and negative match probabilities.
