Abstract: A method is provided of using a set of servers to provide deferential services that have a pre-negotiated time for notice to release the servers. The method includes defining a virtual checkpoint frame interval that is constrained to a duration of up to half of the pre-negotiated time for notice to release the servers. The method includes, responsive to an end of the interval, (i) writing, to a shared state database, a state of processing of the packets and transactions occurring during the interval that are processed by a current one of the servers, and (ii) releasing the packets and transactions occurring during the interval. The method includes copying the packets and transactions occurring during the interval, and the state, from the current server to another server for subsequent processing, responsive to an indication of an instance loss on the current server.

Abstract: A common infrastructure collects data from a plurality of mobile devices and traditional sensors at Internet scale to respond to natural language queries received at different applications. The infrastructure includes a semantic interpreter to translate the natural language query to a data request specification that is processed by the data collection system. The data collection system includes a phenomenon layer that expresses data and information needs in a declarative fashion and coordinates data collection and processing for queries. An edge layer manages devices, receives collection requirements from the backend layer, configures and instructs devices for data collection, and conducts aggregation and primitive processing of data. This layer contains network edge nodes, such as base stations in a cellular network. Each node manages a set of local data generating networked devices.

Abstract: Embodiments are directed to a computer-implemented method of optimizing performance of a computer network. The method includes receiving a request to transmit data from a first location. For each path in a set of paths, where each path comprises a connection allowing the transmission of data from the location, a set of performance measures for the path is determined. For each path in the set of paths, an incremental cost of transmitting the requested data using the path is determined. Thereafter, the performance measures and incremental cost for each path is used to determine which path to use to transmit data. Data is then transmitted using the determined path using multipath transmission control protocol techniques (MP-TCP).

Abstract: A downstream element in a pipeline processing a network flow receives a first request and executes an indexing function to compute an index into a control block for storing state information associated with the data packet. The downstream element transmits a request to an upstream element to include the index as a tag in one or more subsequent data packets that comprises the plurality of network fields and the associated values. Subsequent data packet may be received at the downstream element with the tag having the index information. The downstream element may process the subsequent data packet based on the tag without having to execute the indexing function on the subsequent data packet.
