Example Embodiment

[0026] Embodiment 1: A device of the present invention for reducing the amount of communication data between a remote client and a data center is as follows figure 1 As shown, the content request sending module 11, the content information generating module 12, the judgment module 13, the requested content writing module 14 and the requested content reading module 15 are included. The content request sending module 11 is sequentially connected with the content information generating module 12, the judgment module 13 and the requested content reading module 15 in sequence, and the requested content writing module 14 is connected in parallel with the requested content reading module 15.

[0027] The content request sending module 11 is used for the remote client to send content requests to the data center server, and the data center server receives the sent content requests; the content information generating module 12 is used for the data center server to generate content information...

Example Embodiment

[0028] Embodiment 2: A method of the present invention for reducing the amount of communication data between a remote client and a data center is as follows figure 2 As shown, including the following steps:

[0029] Step S201: One or more remote clients in the branch send a content request to the data center server.

[0030] Step S202: The data center server receives the content request, generates corresponding content information according to the requested content, and sends it to the remote client.

[0031] The content information includes a hash value that matches the requested content calculated by using a hash algorithm using all the original content, and the hash value is extremely small compared with the original content. In this example, the hash algorithm preferably adopts the fifth edition MD5 (Message-Digest Algorithm 5) of the message digest algorithm.

[0032] Step S203: The remote client judges whether the requested content is in the local storage device according to t...

Abstract

The invention discloses a method and apparatus for reducing a communication data size between a remote client and a data center. The method comprises the following steps: firstly, the remote client sends a content request to a data center server; secondly, the data center server generates content information according to the contents of the request and sends the content information to the remote client, and the remote client judges whether the contents of the request are in a local storage device according to the content information; and finally the remote client reads the contents of the request from the local storage device. The invention further discloses an apparatus for reducing the communication data size between the remote client and the data center server. The apparatus comprises a content request sending module, a content information generation module, a judging module, a request content writing module and a request content reading module. By adoption of the method and apparatus disclosed by the invention, the problem that when a plurality of remote clients obtain the same content, the occupation rate of the network bandwidth between the remote clients and the data center server is high, is solved.

Description

technical field [0001] The invention relates to the technical field of distributed storage, in particular to a method and a device for reducing the amount of communication data between a remote client and a data center. Background technique [0002] With more and more remote office models, a situation of one headquarters and multiple branches has formed. In order to improve office efficiency, a data center will be established at the headquarters, and multiple branches will share the data. When a remote client in a branch obtains data, it needs to connect to the data center server through a public or private network, and then send a request, and the data center server will transmit the required data to the remote client. When each remote client in the branch office obtains the same data, these processes need to be repeated. If multiple remote clients obtain the same data at the same time, the data center server needs to transmit multiple copies of the same data. This will c...
