The device comprises a receiving module, a routing determination module and a processing module. By the method and the device, expansion of the distributed file system and mass file content storage can be effectively achieved.

The invention provides a load balancing method and apparatus. In a distributed system, when a write operation is performed on an application request, a specific write identifier is allocated for the write operation of the application request; the write operation of the application request is allocated to a corresponding server according to the write identifier, and a preset identifier of the corresponding server is obtained; and a data identifier of the application request is updated according to the preset identifier of the corresponding server, so as to obtain a new data identifier corresponding to the application request. In the method, the new data identifier of each application request is associated with the preset identifier of the corresponding server. Through adoption of the load balancing method, arbitrary change and capacity expansion of the server in the distributed application system are realized, and the application request can be rapidly guided to the corresponding server as long as the preset identifier of the server is known, so that the processing capability of the system is improved, the response time of the system is shortened, the user experience is improved, and the pressure on the system or a database is also relieved.

The invention provides a distributed relational database based on an HDFS metadata server and a construction method, belonging to the field of distributed databases. The construction method partitions the data according to the coverage of the HDFS system, and stores the data in the regional HDFS according to the partition; the regional HDFS generates metadata according to the stored resource data, and sends the metadata to the corresponding child nodes; and The child node corresponding to the area HDFS stores the metadata, generates a unique identifier according to the metadata, and sends the metadata and the unique identifier to the HDFS metadata server; the metadata server stores the unique identifier, and Metadata and unique identifier are sent to the root node, and a user interface is set, through which layer-by-layer feedback of user requests is performed in the database. The invention establishes the relationship between the parent node and the child node through the metadata server, and realizes the distributed relational data storage of cross-region and multi-branch data sources.

The invention discloses an image restoration method based on image segmentation, and a system therefor; the method comprises: firstly, manually selecting and marking the area to be restored in image by a user; then, carrying out image domain decomposition by mean shift algorithm, and dividing the image into a number of areas; finally, carrying out repeated iterative operation on the area to be restored until all pixels in the area to be restored is filled to be full. The method optimizes the calculation of priority in image restoration algorithm, thus effectively preventing the over expansionof the restored image from a high-texture area to a low-texture area; furthermore, matched block searching standard based on the image domain decomposition can be formulated on that basis, so that anerroneous block can be avoided being introduced; compared with the original image restoration method based on the sample, the effect of the method is more in accordance with the visual expectation ofhuman beings; furthermore, at present, the method is successfully applied to large size area restoration of various images with complex texture and structural characteristics as well as the aspects such as wiping off characters, removing target objects and the like.

The invention provides a cloud parking lot management system. The cloud parking lot management system comprises a parking lot system, a parking lot middleware, a cloud parking lot application and a cloud platform middleware, wherein the parking lot middleware transmits parking lot identification and reported data to the corresponding cloud platform middleware based on a https / http protocol after receiving the reported data of the parking lot system; the cloud platform middleware determines a corresponding key value key according to the identification of the parking lot, and transmits the key and the reported data to the cloud parking lot application based on the https / http protocol; the cloud platform middleware is in long connection with the parking lot middleware, wherein after the issued data and the key are received from the cloud parking lot application based on the https / http protocol, a corresponding long connection link is determined according to the key; the long connection link transmits the issued data to the corresponding parking lot middleware; and then the parking lot middleware transfers the issued data to the parking lot system. The cloud parking lot management system is relatively low in building cost and simple in structure.
