Data processing method, device and system

Abstract

The embodiment of the invention provides a data processing method, device and system, and the method is used for an upper server in a data processing system. The data processing system also comprisesat least one lower server for storing the data contents of a corresponding region. The method comprises the steps: receiving a data read / write request transmitted by a target terminal; obtaining the target user identification information carried by the request; determining a target communication identification corresponding to the target user identification information according to the preset mapping relation relative to the user identification information and the communication identifications of all lower servers; enabling the request to be redirected to the target lower server correspondingto the target communication identification, so as to enable the target terminal to read / write the data in the target lower server according to the data read / write request. According to the embodimentof the invention, the method reduces the storage pressure of the upper server and the data access pressure, and prevents the network bandwidth neck of the upper server.

Description

technical field [0001] The present invention relates to the technical field of data storage, in particular to a data processing method, device and system. Background technique [0002] At present, it is often necessary to transfer the data of various counties, such as the data of civil cases, to the urban area for analysis and aggregation. In this case, it is usually necessary to deploy corresponding servers (ie, lower-level servers) in each county to store the data collected in each county and upload the stored data to urban servers (ie, upper-level servers). ); after receiving the data uploaded by each subordinate server, the server in the urban area analyzes and summarizes the data. [0003] However, this method requires high storage capacity of the upper-level server, and when visitors read data from the upper-level server, it will cause too much data access pressure on the upper-level server, which will occupy too much network bandwidth of the upper-level server. It e...

[0003] However, this method has higher requirements on the storage capacity of the upper-level server, and when visitors read data from the upper-level server, it will cause too much data access pressure on the upper-level server, which will occupy too much network bandwidth of the upper-level server. It even causes network bandwidth bottlenecks on the upper-level server
