Abstract: In operation, packets traverse the packet processing data structure, and the network processing represented by each object in the data structure is applied to each packet. From time to time, the packet processing data structure may need to be updated. Embodiments of the present disclosure provide for lock-free updating of a packet processing data structure by means of epoch-based garbage collection. In embodiments, a particular past packet processing epoch is considered to be no longer referenced by any cores when the sequence numbers recorded in each said memory location are different to the sequence number of that particular past packet processing epoch. The deletion thread checks both whether a past epoch is being referenced by any packets and whether it is being reference by any cores. Thus memory is safely freed without having any impact on any packet processing which may be occurring in parallel to the deletion thread.

Abstract: Embodiments of the present invention provide concepts for tracing a request in a distributed system architecture comprising one or more distributed services. A request is received at a network traffic component on one of a plurality of sockets, which are monitored by a span correlation component. Span data is obtained from the received request and a process identification component is adapted to identify a process associated with the request based on the span data. The span correlation component is adapted to identify a socket connection made by the identified process and correlate the socket connection with the span data, thereby generating span correlation data.

Abstract: A system for railroad directive management is presented. The system can receive a myriad of data related to a directive, track segments, and/or vehicle events on the track and/or track segments. Vehicle- and/or event-specific data can be compared with one or more thresholds, including force thresholds, temporal thresholds, environmental thresholds, and/or event thresholds to determine whether and what kind of directive modification should be instantiated. Specialized algorithms can be implemented to trace vehicle paths along the track to determine whether directive-related segments are traversed, and specialized clustering algorithms can be utilized to cluster data unique to a particular segment on a per-segment basis. The system can be integrated with existing track infrastructure and can further generate alerts to notify coupled systems and/or personnel of directives and/or modification thereof.

Abstract: A system for modeling risk of rail buckling in railroad infrastructure is presented. The system can receive a myriad of data related to railroad tracks and/or railroad operations, and weight the data using specially-designed weighting factors that can be unique to each data type. The weighted data can be transformed via specialized algorithms to generate location scores reflective of a risk isolated to a particular area. The system can further utilize additional specialized algorithms to elucidate how such isolated risk can be extrapolated from one location to another. The system can implement a multilayer approach, formulating one or more layers of risk models and aggregating such models into an overarching risk model that can more-accurately forecast risk of rail buckling in a railroad track.

Abstract: Various systems and methods are disclosed for making and using an anonymized database for an industrial enterprise, such as oilfield operations. Providing statistical performance indicators for groupings of an activity in the oilfield allow for the information in confidential data sets to be shared without compromising the confidentiality of any one data entry. Comparisons may be made between or among oilfields with differing technologies, differing rig configurations, or even different crews when sufficient data are available.

Abstract: Some embodiments support embedding of a notebooks software component in a surrounding host application, thereby promoting consistency of notebook user interfaces and user experiences between different kinds of applications. For instance, the notebook access added to an integrated development environment (IDE) may be aesthetically consistent with the notebook access added to a business analytics tool from the same vendor as the IDE. Departures from the aesthetic are still supported, e.g., a notebook access provided in a video gaming environment to teach gamers programming skills may have the same aesthetic as the simulated world of the video game, rather than an IDE aesthetic or an enterprise software aesthetic. Direct integration or proxied integration architectures may be used. Efficiencies may be gained by distinguishing between notebook viewing, editing, and executing operations, and providing more computationally expensive resources only as needed for the notebook access being performed.

Abstract: A system and method for strategic track and maintenance planning (STAMP) that can provide an organizational and adaptive infrastructure configured to facilitate railroad asset management and capital planning is presented. The system can provide a railroad asset inspector with relevant data for an assigned inspection segment. Location-based functionality can acquire a device's precise location and provide only the data necessary for the inspection of a particular railroad asset by providing step-by-step input prompting based upon the device location. The system provides adaptive thresholding of asset-related criteria to determine whether and when asset maintenance should occur. The system can acquire inspection data for one or more railroad assets, apply a data optimization algorithm to the inspection data, analyze railroad asset-related data (including historical data), and generate an optimized capital plan with a schedule for railroad asset maintenance and replacement.

In addition, upon detection of the presence of multipath error in a signal, a signal bandwidth may be increased to as to include additional position reference symbols (PRS) that are included in a determination of a propagation delay, and in turn, a range. In addition, use of a different number of symbols in a signal based on signal SNR is presented.

Abstract: The techniques disclosed herein improve existing systems by receiving a packet to process and determining an associated packet processing graph for the packet. In response to determining that the associated packet processing graph contains an action comprising a set of rules for modifying the packet processing graph, a table to modify in the packet processing graph is accessed based on a table identifier in the action. The accessed table is modified by inserting one or more table rows into the packet processing graph and for each inserted table row, inserting a set of template actions containing prepopulated fields. The modified table is used to process subsequent packets.

Abstract: Approaches for detecting and/or rejecting fraudulent positioning system signals at one or more positioning system receivers. The receivers may establish a time search window that may be maintained beyond a time in which a fraudulent signal is expected to move away from an authentic signal a sufficient amount so as to fall outside the time search window. Various approaches are described for updating the time signal at the receiver to maintain accuracy without acquiescing to the introduced bias of a fraudulent signal. Also, an approach for evaluation of candidate signals for consistency at one or more stationary receivers is described. Also, approaches for collective evaluation of signals provided from networked receivers are described to provide sentry receivers operative to detect and alert the presence of a fraudulent signal.

Abstract: A process or may reduce start latency of serverless microservices. The processor may detect an incoming request or event to an application in a serverless microservice environment. The incoming request or event may initiate a chain of invocations of one or more microservices of the application. The processor may select an amount of selected microservices from the one or more microservices of the application. The amount of selected microservices may perform a task of the incoming request or event. The task may apply one or more predefined application-specific rules to one or more elements of the incoming request or event to determine the amount of selected microservices. The processor may trigger scaling up activation of the one or more microservices of the application. The processor may invoke the one or more microservices of the application to match the amount of selected microservices.
