Abstract: One aspect provides a method and system for managing address resolution requests in a network. During operation, a gateway of the network advertises a route for sending address resolution requests and determines whether a cached entry corresponding to an address resolution request received via the route exists in a neighbor table. In response to determining that the cached entry exists, the gateway responds to the address resolution request based on the cached entry; in response to determining that the cached entry does not exist, the gateway replicates the address resolution request to edge devices in the network, thereby facilitating discovery of a target host corresponding to the address resolution request.

Abstract: The present disclosure relates to methods and apparatus for graphics processing. The present disclosure can calculate a center-edge distance of a first pixel, the center-edge distance of the first pixel equal to a distance from a first pixel center to one or more edges of a first primitive. Additionally, the present disclosure can store the center-edge distance of the first pixel when the first primitive is visible in a scene. The present disclosure can also determine an amount of overlap between the first pixel and the first primitive. Further, the present disclosure can blend a color of the first pixel with a color of a second pixel based on at least one of the center-edge distance of the first pixel or the amount of overlap between the first pixel and the first primitive.

Abstract: A switch that can report unavailability in a label-switched network is provided. During operation, the switch can determine that a label-switched path is unavailable for forwarding a packet. The switch can then generate a notification message for collecting unavailability information at a respective upstream hop of the label-switched path. The notification message includes a depth indicator indicating the depth of collected unavailability information and an ingress label of the packet at the switch. If the switch is an intermediate switch on the label-switched path, the switch can forward the notification message to an upstream switch on the label-switched path, thereby allowing the upstream switch to collect further unavailability information in the notification message.

Abstract: Systems and methods are provided for detecting changes in network activity that are depicted in a routing table. The routing table may be stored as a search tree data structure (e.g., Merkle Patricia Tree) to mimic a standard routing table and reduce the search time to find the desired route by allowing the router to traverse the search tree data structure more efficiently. Additionally, the metadata of the tree may be provided to an unstructured machine learning model (e.g., K-means) to identify new clusters of routes week-over-week and generate an alert with any changes. Changes are identified in near real time and dynamically at the router (not a central device) to reduce the time needed to respond to network changes.

Abstract: A time series forecasting service system is disclosed. The system identifies a set of cross-validation parameters to be used for cross-validating a model to be used for generating a requested forecast. The requested forecast includes a time series dataset and a forecast horizon identifying a number of time steps for which a forecast is to be made using the time series dataset. The system identifies an objective function to be minimized for determining optimal values for the set of cross-validation parameters and identifies constraints for the cross-validation parameters. The system uses an optimization technique to determine the optimal values for the cross-validation parameters. The optimization technique performs processing that determines the optimal values by minimizing the objective function while satisfying the set of constraints. The system uses the optimal values for the cross-validation parameters to perform cross-validation of the model to be used for making the requested forecast.

Abstract: Features are disclosed for managing multiple hosts that stream sequential data to nodes for propagation. The hosts can include a primary host and a failover host that each store a replica of the sequential data. A computing device can monitor the hosts and identify the occurrence of a failover event for the primary host. For example, the computing device may determine the schema has been modified. The computing device can further determine to failover to the failover host based on the failover event. The computing device can insert a flip task into the stream of sequential data for the primary host. The insertion of the flip task may be automatic. Further, each node reading from the stream of sequential data for the primary host may encounter the flip task and failover to the failover host at the same logical position but a different absolute position.

Abstract: A system and method for performing visual localization is disclosed. In aspects, the system implements methods to generate a global point cloud, the global point cloud representing a plurality of point clouds. The global point cloud can be mapped to a prior map information to locate a position of an autonomous vehicle, the prior map information representing pre-built geographic maps. The position of the autonomous vehicle can be estimated based on applying sensor information obtained from sensors and software of the autonomous vehicle to the mapped global point cloud.

Abstract: In some aspects, the disclosure is directed to methods and systems for machine learning-based data extraction using multiple string searching models. String extraction logic may differ depending on the type of document received. For documents identified to contain line item structures, broader searching models are applied to the document to account for the increased variability of data in the document inherent in data organized in line item structures. For documents identifier to contain non-line item structures, stricter searching models are applied to the document to account for predictable data in the document associated with data organized in non-line item structures.

An integrated analytics layer performs one or more analytical operations on the flow behavior information to obtain network insights. A presentation layer filters and plots information obtained from the data layer, the inline heuristics layer, and the integrated analytics layer, based on a user input.

Abstract: A security client can efficiently authenticate an application during I/O request handling by maintaining a white list that identifies processes that have been created for authenticated applications. The security client can register to be notified when a process is being created. When such a notification is received, the security client can authenticate the application for which the process is being created and then add an entry to the white list that includes the process identifier of the process being created. Then, when the process subsequently generates I/O requests, the security client can use the white list to quickly determine that the process pertains to an authenticated application and allow the I/O requests to modify protected artifacts.
