    Abstract: A network analytics controller in a computer network receives specification of a network analysis task. The controller creates maplets. Each maplet corresponds to an agent executing on a network node in the computer network. Each maplet specifies the network data collection configuration, collected data processing, and processed data reporting to be performed to support the network analysis task at the node executing the corresponding agent. The controller communicates the maplet corresponding to the agent over the computer network to each agent. Each agent receiving a maplet configures its corresponding network node for network data collection, collected data processing, and processed data reporting in accordance with the received maplet. Each agent receiving a maplet collects and processes network data, and reports the processed data to the controller, in accordance with the configuration. The controller aggregates, as the result of the network analysis task, the data reported from each agent.

    Abstract: In a system and method for order-independent stream query processing, one or more input streams of data are received, and the one or more input streams are analyzed to determine data which is older than an already emitted progress indicator. The data which is older than the already emitted progress indicator is partitioned into one or more partitions, and each of the one or more partitions are independently processed using out-of-order processing techniques. A query is received, rewritten and decomposed into one or more sub-queries that produce partial results for each of the one or more partitions, where each of the one or more sub-queries correspond to a partition. A view is also produced that consolidates the partial results for each partition. The partial results are consolidated at a consolidation time specified by the query to produce final results, and the final results are provided.

    Abstract translation: 在用于与秩序无关的流查询处理的系统和方法中，接收一个或多个输入数据流，并且分析一个或多个输入流以确定比已经发射的进度指示符更早的数据。 比已经发射的进度指示符更老的数据被分割成一个或多个分区，并且使用无序处理技术来独立地处理一个或多个分区中的每一个。 查询被接收，重写并分解成一个或多个子查询，其产生针对一个或多个分区中的每个分区的部分结果，其中一个或多个子查询中的每一个对应于分区。 还会生成一个整合每个分区的部分结果的视图。 部分结果在查询指定的合并时间内合并，以生成最终结果，并提供最终结果。

    Abstract: In an embodiment, an improved computer-implemented method of efficiently determining actions to perform based on data from a streaming continuous queries in a distributed computer system comprises, at a central control computer, receiving a streaming continuous query and a rule-set; wherein the rule-set comprises decision data representing decisions based on attributes produced by the query, and action data representing end actions based on the decisions, wherein the attributes comprise data processed by one or more networked computers; separating the streaming continuous query into a sub-query executable at one or more edge computers; categorizing end actions from the set based on decisions requiring attributes available from the sub-query into a set of one or more edge expressions that are configured to be evaluated at an edge agent to cause an action; providing the set of edge expressions and the sub-query to at least one edge computer with instructions to process visible attributes on the edge computer and to evaluate the set of one or more edge expressions independently from the central control computer; wherein the method is performed by one or more computing devices.
