20160164719 | FAULT TOLERANCE METHOD FOR DISTRIBUTED STREAM PROCESSING SYSTEM - A fault tolerance method is provided for a distributed stream processing system. The method includes: obtaining, by a working node, information of a failed node, and receiving retransmission data sent by an upstream node, where the retransmission data is originally sent by a source node to the failed node; determining, according to the information of the failed node, whether the failed node is related to the working node; and if the failed node is related to the working node, processing the received retransmission data, and sending the processed retransmission data to a downstream node. In the present application, retransmission data sent by an upstream node is received by a working node, and after it is determined that a failed node is related to the working node, the received retransmission data is processed, so that the retransmission data sent by the upstream node is processed only when the failed node is related to the working node. | 2016-06-09 |
20160164720 | SYSTEM AND METHOD USING RSVP HELLO SUPPRESSION FOR GRACEFUL RESTART CAPABLE NEIGHBORS - A system, method and apparatus adapting one or more routers or nodes in a network to operate in a first mode to exchange hello messages with neighboring nodes to indicate thereby active or live status, and to operate in a second mode to avoid the use of hello messages by opportunistically relying upon service or management protocols to convey active or live status. | 2016-06-09 |
20160164721 | ANOMALY DETECTION IN TIME SERIES DATA USING POST-PROCESSING - Described herein are systems, mediums, and methods for detecting anomalies in a signal by applying two analysis algorithms in parallel to the signal. The results of the two algorithms are combined during a post-processing step. The first analysis algorithm detects a first set of anomalies using amplitude-based anomaly detection method. The first set of anomalies includes large dips/spikes with short duration and large week-by-week variations with long duration. The second analysis algorithm detects a second set of anomalies using statistics-based anomaly detection method. The second set of anomalies includes subtle changes with sharp edges and medium duration. The first set of anomalies and the second set of anomalies are merged in a post-processing step. All spikes and all changes that satisfy a pre-determined criteria are removed from the merged data. Adjacent anomalies are concatenated. The resulting set of anomalies is used to determine service outage at a network server. | 2016-06-09 |
20160164722 | ZERO-DOWNTIME, REVERSIBLE, CLIENT-DRIVEN SERVICE MIGRATION - A computer system may provide zero-downtime, reversible, client-driven service migration to migrate a client from a current service to a new service. The computer system may configure the client to operate in a dual-write, old-read mode in which the client issues write requests to both the current service and the new service and issues read requests only to the current service. The computer system may configure the client to operate in a dual-write, new-read mode in which the client issues write requests to both the current service and the new service and issues read requests only to the new service. | 2016-06-09 |
20160164723 | TYPE-TO-TYPE ANALYSIS FOR CLOUD COMPUTING TECHNICAL COMPONENTS - Cloud computing has emerged as an extremely popular implementation option for a wide range of computing services. However, provisioning services into the cloud is an extremely difficult technical challenge. This is due in part to the regular emergence of new cloud service providers, as well as the routine changing and reconfiguration of the disparate computing platforms, services, assets, supported technical components, and other features offered by the service providers. An analysis architecture determines how to map a particular technical component into the execution environment of any particular service provider. | 2016-06-09 |
20160164724 | INSTALLATION OF NETWORKABLE DEVICES - Embodiments described herein include systems, apparatuses, and methods for attempting to wirelessly communicate with a networkable device with a mobile device to retrieve an identifier for the networkable device; receiving the identifier from the networkable device; storing the identifier in the mobile device; and sending a request to a provisioning server to provision the networkable device. | 2016-06-09 |
20160164725 | Wireless System Package and Communication Method of Wireless System Package and Communication Device - A wireless system package includes a substrate, an external non-volatile memory, a first integrated circuit, and a second integrated circuit. The first integrated circuit includes a System on Chip unit, a bus, a first clock unit, a first terminal, a second terminal, and a third terminal. The second integrated circuit includes a second heterogeneous communication module, a second clock unit, a first terminal, and a second terminal. The first integrated circuit or the second integrated circuit includes a first heterogeneous communication module for providing and processing a first wireless signal. A capacity of the external non-volatile memory is larger than a capacity of the internal non-volatile memory. | 2016-06-09 |
20160164726 | COMMUNICATION AND DATA HANDLING IN A MESH NETWORK USING DUPLEX RADIOS - Wireless-conferencing radios communicate directly with each other without a bases station using a multiple access protocol, such as Time Division Multiple Access (TDMA). Wireless-conferencing radios can be formed into groups and larger mesh networks. Some groups of wireless-conferencing radios use frequencies in a cellular band to communicate. | 2016-06-09 |
