Abstract
The invention provides a distributed file security storage system capable of correcting file transmission error and a method of the system. The method includes that in the process of network data transmission, a data transmitting end computes checksums corresponding to transmission files and transmits the checksums to a target system together when transmitting file content; after receiving the transmission files, the target system computes checksums of the transmission files and compares the checksums with the received file checksums to confirm whether the checksums are identical or not, if yes, transmission is correct, and otherwise, the target system sends out a request for requiring the data transmitting end to retransmit data. By means of correctness verification of file transmission, error files appearing during transmission are discovered in time, and retransmission is performed, so that loss caused by file transmission error is avoided, and high error tolerance of the system is realized.
Description
Technical field
The present invention relates to a kind of distributed document safe storage system and method thereof of correcting file transfer mistake, particularly relate to a kind of be applicable to the correction file transfer mistake of internet intelligent TV distributed document safe storage system and method.
Background technology
At present, Internet user increases fast, and a large amount of user's access is all a huge test to the data throughout of system platform and system concurrency amount.In file interaction process frequently, the mistake caused because of user misoperation or network reason can be there is unavoidably, this fault-tolerance just needing system can provide enough, the operation for this row mistake is carried out correcting and is carried out operation rollback in other words, avoids or alleviate the loss that it causes.
Existing distributed file system focuses on the high-throughput aspect of system mostly, and it is fewer that the Fault-Tolerant Problems for system is considered.
In distributed file system, because number of clients is many, access is frequent, there will be the faulty operation of file unavoidably, and the change of the uploading of such as mistake, mistake or more grave error are deleted, cause accidental change or the loss of file content, cause unexpected loss.In addition, because the file error that Internet Transmission mistake causes also is cause one of unsafe major reason of system file.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of can the distributed document safe storage system of high fault-tolerant correction file transfer mistake and method thereof.
The technical solution used in the present invention is as follows:
Correct a distributed document safe storage system for file transfer mistake, it is characterized in that: comprise
Data sending terminal: the School Affairs calculating its correspondence according to data block contents;
Goal systems: the network data receiving transmission.
Based on the distributed document method for secure storing of above-mentioned correction file transfer mistake, its method step is:
A, in the process of carrying out network data transmission, data sending terminal calculates School Affairs corresponding to this transfer files, and when transfer files content, School Affairs is transferred to goal systems together;
Whether after b, goal systems receive described transfer files, calculating its School Affairs and see with the file verification that receives and comparing identical, is illustrate that transmission correctly, otherwise enter next step;
C, goal systems send request, require that data sending terminal carries out data re-transmission.
As preferably, described step a is identical with the method calculating School Affairs in step b.
As preferably, be all calculate School Affairs corresponding to transfer files according to data block contents in described step a and step b.
As preferably, be all adopt MD5 algorithm to calculate School Affairs corresponding to transfer files in described step a and step b.
Compared with prior art, the invention has the beneficial effects as follows: the present invention, by the verification of correctness to file transfer, occurs the file of mistake, and retransmits in Timeliness coverage transmitting procedure, the loss avoiding file transfer mistake to bring, realizes the high fault tolerance of system.
Accompanying drawing explanation
Fig. 1 is the schematic flow sheet of the present invention's wherein embodiment.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Arbitrary feature disclosed in this specification (comprising any accessory claim, summary and accompanying drawing), unless specifically stated otherwise, all can be replaced by other equivalences or the alternative features with similar object.That is, unless specifically stated otherwise, each feature is an example in a series of equivalence or similar characteristics.
Correct a distributed document safe storage system for file transfer mistake, comprise
Data sending terminal: the School Affairs calculating its correspondence according to data block contents;
Goal systems: the network data receiving transmission.
As shown in Figure 1, in this specific embodiment, based on the distributed document method for secure storing of above-mentioned correction file transfer mistake, its method step is:
A, in the process of carrying out network data transmission, data sending terminal can calculate School Affairs corresponding to this transfer files, and when transfer files content, School Affairs is transferred to goal systems together;
After b, goal systems receive described transfer files, calculate its School Affairs and see whether both are identical with the file verification received with comparing, identical then explanation transfer of data is correct, without the need to passing again, not identical, data transmission fault is described, has needed again to pass again, so enter next step;
C, goal systems send request and represent that file data transfer is wrong, need again to transmit, require that data sending terminal carries out data re-transmission.
In this specific embodiment, by verifying the data correctness of file transfer, there is the file of mistake in Timeliness coverage transmitting procedure, and retransmitting, the loss avoiding file transfer mistake to bring, realize the high fault tolerance of system.
Described step a is identical with the method calculating School Affairs in step b, is convenient to compare, and draws correcting errors of transfer of data.
Be all according to data block contents in described step a and step b, the content of file is audited, calculate the School Affairs that transfer files is corresponding.
Be all adopt MD5 algorithm to calculate School Affairs corresponding to transfer files in described step a and step b, cipher round results is good, and fail safe is high, is not easy to be tampered, and adopts MD5 algorithm highly versatile.
Claims (5)
