The invention provides a flow table updating consistency maintaining method based on a software defined network. The flow table updating consistency maintaining method based on the software defined network comprises the following steps that A) a controller analyzes a flow table; B) in initial switches V1, all switches upload data packets which are influenced by a flow table updating process to the controller through a control plane; C) the controller writes a flow table to be newly added into succeeding switches V2; D) after the controller waits for a whole-network end-to-end time delay, the controller writes a flow table to be modified into the succeeding switches and deletes a flow table to be deleted; and E) the controller updates the flow tables in the initial switches V1. The flow table updating consistency maintaining method based on the software defined network has the advantages that the complexity of additional network management is avoided and the load of the control plane is reduced; and at the same time, on the premise that the updating consistency is guaranteed, the entire flow table updating time is shortened.

The embodiment of the invention further discloses a cloud data center and a system. By the adoption of the system mirror image file updating method, the system mirror image file updating time is shortened, and storage space is reduced.

The invention discloses a distributed storage method, which comprises the following steps: when a first block chain node in the block chain network initiates a transaction request, the first block chain node performs a consensus operation on the blocks carrying the transaction request, and broadcasts the blocks after the consensus operation to other block chain nodes in the block chain network; The remaining block chain nodes obtain transaction request data from the blocks after the common operation, and issues a creation, insertion or table query request through the intelligent contract initiation table to invoke the key-value pair interface and the storage engine to transmit the transaction request to the AMDB data proxy; The remaining block chain nodes execute corresponding database operation on the database according to the transaction request data through the AMDB data agent. The invention also discloses a distributed storage system and a device. The invention can improve the datastorage efficiency in the block chain and reduce the data update time.

Project schedules do not include tasks for Globalization. This method defines and automatically creates globalization tasks that are to be performed during the development of an international product. In this method, a table is created containing various volumes of data and the amount of time required to translate each volume of data. For each volume of data, there is a corresponding translation productivity rate. When a globalization schedule is desired, a user inputs to the method of the present invention, a start date for the Globalization test effort and the date of the product release to manufacturing date. A user then moves the pointer of the constant representing a defined volume of data to the cell in the volume of data table to the volume that corresponds to their current volume for their product. The method then determines the amount of time needed to perform the globalization translation of the volume of data. The method then generates a globalization task schedule within a product development project. In addition, the present invention automatically creates an overall schedule and status report of milestones suitable for team and managerial distribution.

A lossless handover method in vehicular wireless networks is disclosed which is capable of reducing a handover delay and reducing overhead caused by duplicate address detection (DAD) for a new Care-of-Address (CoA) by dividing a handover process into handover at road-sections and handover at intersections. In the handover method, a vehicle continues to use an original CoA configured at an original access router at road-sections even though an AR is changed, thereby reducing a handover delay. A new CoA is configured only at intersections to reduce a binding update time of a home agent which is remotely present in an external network at road-sections. When performing the DAD for a new CoA at intersections, since the vehicle performs the DAD as a background process while performing communication using an original CoA, overhead caused by the DAD can be reduced.

A memory updating system for a field device involves a fieldbus, one or more field devices that incorporate a nonvolatile memory and are connected to the fieldbus, a host system that is directly or indirectly connected to the fieldbus and transmits an updating instruction and updating data to one of the field devices in order to update the nonvolatile memory of the field device, and a current control circuit that controls a current provided from the fieldbus. The current control circuit increases the current provided from the fieldbus to a value greater than a normal value before the field device erases data stored in the nonvolatile memory, and returns the current provided from the fieldbus to the normal value after the field device completes the erasing of the data stored in the nonvolatile memory.
