Abstract
The present invention relates to a kind of CDN node content authentication method and system, including source station, calibration tool, CDN node, the storage file of source station generates its inspection of document code；CDN node generates the file verification code of simultaneously storage file in cache file simultaneously；Calibration tool is compared by communicating acquisition file verification code with source station and CDN node.Calibration tool is http protocol head response field extension mode with source station and CDN node communication mode.It is using X Verify Tag as the field name of check code that calibration tool, which is http protocol head response field extension mode with source station and CDN node communication mode, and the value of check code is the value of ETag.It is relatively high that the present invention verifies efficiency；It is relatively high to verify accuracy rate；System maintenance operating cost is low.
Description
Technical field
The invention belongs to information technology fields, more particularly to a kind of CDN node content authentication method and system.
Background technology
In CDN distributed systems, there are a large amount of node, each node has cached a large amount of file again.The text of caching
Part content requires consistent with source station file content.When source station, some file content changes, fringe node has delayed
The respective file deposited will first do removing action, and when having waited access, fringe node caches the latest document content of source station again.
Due to the complexity of the framework of CDN distributed systems, over time and continuous file content changes, specific
Occurs abnormal, incorrect 100% removing, it is likely that edge section occur under situation, such as when cleaning fringe node file cache
The file content of point cache and the inconsistent situation of source station file.Since node and content quantity are huge, this file content is not
Unanimously relatively it is difficult to find.
Then, the problem of needs verify specified edge cache file and the comparison of source station file is just produced.
In traditional scheme, a calibration tool is usually write, analog subscriber is accessed and verified.Calibration tool arrives first source station
File download is returned, the MD5 values of file are calculated, the file link (URL) then verified as needed, calibration tool is to often
After the file for downloading corresponding caching on a fringe node, MD5 values are calculated separately, are compared with the MD5 values of source station file, most
The consistent or inconsistent conclusion of each fringe node is obtained afterwards.
The disadvantage of traditional scheme：1, low to specific efficiency.Calibration tool must be to verifying needs on each fringe node
File download gets off, then executes MD5 digest calculating, and the time of download may be very long, often completes primary download, will carry out MD5
It calculates, efficiency is very low, and especially when the file for needing to verify is more and larger, calibration tool is to network bandwidth and stores all
It has higher requirements.2, verification accuracy is difficult to accomplish 100%.Since the link condition of calibration tool to each fringe node differs
Sample, it is possible to download unsuccessful or download imperfect, lead to obtain inaccurate check results.
Invention content
The present invention provides the content authentication method and systems of CDN node more than one, it is therefore intended that improves verification efficiency and verification
Accuracy.
The storage file of this CDN node content authentication system, including source station, calibration tool, CDN node, source station generates
Its inspection of document code；CDN node generates the file verification code of simultaneously storage file in cache file simultaneously；Calibration tool by with source
It stands and CDN node communication obtains file verification code and compared.
Calibration tool is http protocol head response field extension mode with source station and CDN node communication mode.
It is with X- that calibration tool, which is http protocol head response field extension mode with source station and CDN node communication mode,
Verify-Tag is the field name of check code, and the value of check code is the value of ETag.
This CDN node content authentication system, a kind of corresponding CDN node content authentication method, comprises the steps of：
Step 1, source station generate file verification code；
Step 2, CDN node produce cache file check code；
Step 3, calibration tool obtain source station and CDN node check code, not to determining whether file is consistent.
Step 3 calibration tool is http protocol head response field extension mode with source station and CDN node communication mode.
Step 3 calibration tool and source station and CDN node communication mode be http protocol head response field extension mode be with
X-Verify-Tag is the field name of check code, and the value of check code is the value of ETag.
Advantages of the present invention：
It is relatively high to verify efficiency；It is relatively high to verify accuracy rate；System maintenance operating cost is low.
Description of the drawings
Fig. 1 is traditional method of calibration processing mode；
Fig. 2 is the method for calibration processing mode of the present invention.
Specific implementation mode
It elaborates below to the preferred embodiment of the present invention.
This CDN node content authentication system, including source station, calibration tool, CDN node, Fig. 1 show traditional solution party
The mode of case；The storage file of source station generates its inspection of document code in this programme；CDN node is generated and is deposited simultaneously in cache file
Store up the file verification code of file；Calibration tool is compared by communicating acquisition file verification code with source station and CDN node, is such as schemed
Shown in 2.
Calibration tool is http protocol head response field extension mode with source station and CDN node communication mode.
It is with X- that calibration tool, which is http protocol head response field extension mode with source station and CDN node communication mode,
Verify-Tag is the field name of check code, and the value of check code is the value of ETag.
This CDN node content authentication system, a kind of corresponding CDN node content authentication method, comprises the steps of：
Step 1, source station generate file verification code；
Step 2, CDN node produce cache file check code；
Step 3, calibration tool obtain source station and CDN node check code, not to determining whether file is consistent.
Step 3 calibration tool is http protocol head response field extension mode with source station and CDN node communication mode.
Step 3 calibration tool and source station and CDN node communication mode be http protocol head response field extension mode be with
X-Verify-Tag is the field name of check code, and the value of check code is the value of ETag.
Certainly, those skilled in the art are it should be appreciated that above example is intended merely to illustrate the present invention
, and not limitation of the invention, as long as within the scope of the invention to the variation of above example, modification all in the present invention
Protection domain within.
