20130272162 | Virtualized Wireless Communication System and Establishing Method thereof - The present application discloses a virtualized wireless communication network and an establishing method thereof. The virtualized wireless communication network system includes a plurality of virtual nodes, the plurality of virtual nodes being divided into multiple virtual node cliques according to interference relations among the plurality of virtual nodes, wherein, each virtual node represents a wireless communication node; and a plurality of clique communication management modules that are one-to-one associated with the multiple virtual node cliques, wherein, each clique communication management module is configured to manage data exchange between an associated virtual node clique and other virtual node cliques, so as to emulate communication behavior of the wireless communication node. The present invention has many advantages such as high flexibility, good scalability, low cost and the like. Compared with a centralized virtualization solution, this solution can significantly reduce management data overhead and thus enhance the real-time behavior of the whole system. | 10-17-2013 |
20150120221 | METHOD AND SYSTEM FOR DETECTING ISLANDING EFFECT IN POWER ELECTRICAL NETWORK TOPOLOGY - In an approach for detecting islanding effect in a power electrical network topology, a computer processor finds, in the power electrical network topology, a point of common coupling between a load and a distributed generation with potential islanding effect as well as a substation supplying power to said point of common coupling; collects operating parameters of the power grid in vicinity of said point of common coupling as well as in vicinity of said substation; determines whether islanding effect exists in said distributed generation and the load in accordance with a variation characteristic of the operating parameters of the power grid in vicinity of said point of common coupling and the operating parameters of the power grid in vicinity of said substation. Higher degree of accuracy and sensitivity of detecting islanding effect is achieved without compromising the energy quality on user side according to embodiments of the present invention. | 04-30-2015 |

20150378835 | MANAGING DATA STORAGE SYSTEM - In one embodiment, a method for managing a data storage system includes: in response to receiving a data object, sorting data records in the data object on the basis of a first query so as to form a first backup; causing the first backup to be stored in the data storage system; and cause to be stored, in an index of the data storage system, the first query and a first address of the first backup in the data storage system. | 12-31-2015 |
20150379024 | FILE STORAGE PROCESSING IN HDFS - A method and system for processing file storage is provided. The method includes receiving a file storage request and determining a file size of a file which is requested to be stored. In response to determining that the file is a small file, a request is sent to an HBase to store the file into the HBase. In response to determining that the file is a large file, a request is sent to a HDFS to store the file into the HDFS. Information associated with the file is stored in a record. | 12-31-2015 |
