Embodiment Construction

[0047] The specific implementation of the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0048] see figure 1 , figure 1is a schematic structural diagram of a communication system provided by the present invention, the communication system includes: a terminal 101, a verification module 102 and a server system 103; wherein,

[0049] After the server system 103 receives the file download request sent by the terminal 101, it returns the descriptive information of the file to the terminal 101; the terminal 101 obtains from the server system 103 each component that forms the file to be downloaded according to the file download address provided by the received descriptive information. data block;

[0050] The verification module 102 obtains algorithm parameters from the terminal 101 and the server system 103, and calculates the verification code of each data block according to the preset algorithm; the...

Abstract

The invention provides a communication system, an equalization server and a data verification method. The method comprises the following steps: after a server system receives a file downloading request transmitted by a terminal, the description information of files is returned to the terminal; the terminal obtains each data block forming the files from the server system according to a file downloading address provided by the received description information; and a verification module obtains an algorithm parameter from the terminal and the server system and calculates the verification code ofeach data block according to a preset algorithm. The description information comprises a verification reference code which is used for verifying the effectiveness of each data block; the verificationmodule is used for comparing the verification code with the verification reference code; if the verification code is identical with the verification reference code, the data block is effective, and otherwise, the data block is ineffective. The technical scheme can effectively reduce information quantity carried by the description information, save the transmitting resources and reduce the transmitting cost for checking the files.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a communication system, a balance server and a data verification method. Background technique [0002] Service providers usually provide file services to users based on the network. In some cases, in order to prevent a server from being difficult to handle the centralized download of many users at the same time, the file is often divided into multiple data blocks, and multiple data blocks are deployed on different servers to share the load of the same server. After the user obtains the deployment information, he can download each data block belonging to the same file from the relevant server. [0003] For example, the existing technology is often based on a point-to-point download (BT, BitTorrent) system, which provides file services for many concurrent users at the same time. In the BT system, the terminal realizes the server function of providing file services for other...
