A snapshot of the data of a block storage resource is taken and made available over a network via iSCSI. The snapshot can be either read-only or read-write.

The invention provides a method and a routing device for realizing network authentication through Bluetooth matching. A Bluetooth function is added to a router, a Bluetooth signal is set in a specified range, the concrete distance can be adjusted according to the magnitude of Bluetooth power, and the distance is used for replacing password authentication. When a mobile phone enters a signal range of the Bluetooth of the router, the MAC (media access control) address of a wireless network card of the mobile phone is transmitted to the router through the Bluetooth by the Bluetooth function of the mobile phone, and after the routing device receives the MAC address, the MAC address of the mobile terminal is used as a client side capable of being accessed to network authority, and is stored on storing equipment. Through the method and the routing device, a user in a limited region can conveniently access a WiFi (wireless fidelity) network, and the working efficiency is improved.

Disclosed is a context modeller (103) used in decoding data (202) encoded using Context Adaptive Binary Arithmetic Coding, said context modeler (103) comprising a Read Only Memory (1001) for storing uninitialized context model values, said uninitialized context model values being stored in the Read Only Memory (1001) in a manner that enables a plurality of uninitialized context model values to be read from the Read Only Memory (1001) in a single clock cycle, an Arithmetic Logic Module (1003) comprising a plurality of parallel processing paths (2202-2207), each said processing path comprising a plurality of pipeline stages, a Random Access Memory (1005) and a memory controller (1008) for determining, using the Arithmetic Logic Module (1005) operating on said plurality of uninitialized context model values read from the Read Only Memory (1001) in each clock cycle, initialized context model values for storage in the Random Access Memory (1001) based upon header information in said incoming encoded data (202).

The invention discloses an alternating-direct current series-parallel port distribution network and a comprehensive dispatching control method thereof, and belongs to the field of port distribution power and distribution network automation. The distribution network comprises a general step-down station, a branch substation or a switch-on / switch-off station and various distribution subsystems; a multi-channel feeder of the general step-down station provides alternating current power for the various distribution subsystems through the branch substation or the switch-on / switch-off station; each distribution subsystem comprises a shore electronic system, a shore bridge subsystem, a field bridge subsystem, a power charging and converting station subsystem for electric port trailers, a new energy subsystem and a production life subsystem; each distribution subsystem utilizes an alternating current distribution transformer and an AC / DC converter to construct a direct current bus of the distribution subsystem, and the direct current buses of the distribution subsystems are in direct current interconnection through direct current interconnection protection switches; each distribution subsystem is internally provided with multiple sections of direct current buses, and the multiple sections of direct current buses are in direct current interconnection through direct current interconnection protection switches. According to the alternating-direct current series-parallel port distribution network and the comprehensive dispatching control method thereof, the optimal power supply and comprehensive dispatching control of the port distribution network can be achieved.

An embodiment of the invention provides a data permission control method and device for application system clusters. The method includes: receiving an access request which a user submits in an application system cluster; when the fact that the user has data permissions is determined according to the access request, acquiring a data permission set corresponding to the user, to be specific, searching for one or multiple characters corresponding to the user, searching for one or multiple standard functions corresponding to the one or multiple characters and searching for one or multiple dimensions corresponding to the one or multiple standard functions; acquiring a current data permission set of the user according to the one or multiple dimensions. The data permission set includes standard data permission sets. The data permission control method and device for application system clusters according to the embodiment has the advantages that parameter-based fine-grained permission control is achieved, few modifications are made to the application system clusters, few invasions are caused to the application system clusters, and accessing is simple.

In light emitting diode (LED) control, a plurality of duty cycle signals corresponding to a plurality of LEDs are stored in a dual-port memory by memory mapping. By sampling, the stored duty cycle signals are outputted to generate a plurality of parallel single-bit data each having one single bit. After the single-bit data are converted by a data transmission module, each bit of the single-bit data is serially outputted to a drive module to drive the LEDs. Thus, the ON duty cycles of the LEDs are modulated by pulse width modulation (PWM), light emitted from the LEDs are mixed in time-domain, and the brightness of the LEDs can be controlled.
