Step 201, the first UCD server obtain the information for the CSP server that the user's registration is crossed.

Specifically, the first UCD server stores registration information of the user at the 3rd CSP server.As described above, this The CSP server registered customers as in inventive embodiments is referred to as the 3rd CSP server.The user services in the 3rd CSP Registration information at device includes the mark (such as link address of the 3rd CSP server) of the 3rd CSP server, user in third The account name and password of CSP server registration.Registration of the first UCD server according to the user at the 3rd CSP server Information, obtains the information of the 3rd CSP server from the 3rd CSP server, and the information of the 3rd CSP server includes User is in the free memory of the CSP server, the maximum file size and/or the 3rd CSP of the support of the 3rd CSP server The connection speed of server.

In the present embodiment, it is assumed that user registers at CSP server A and CSP server B respectively, therefore, the first UCD clothes Business device stores user in CSP server A and CSP server B, the registration information of CSP server C, and respectively to CSP server The information of CSP server A and CSP server B is obtained at A and CSP server B.CSP server A, CSP server C and CSP clothes Business device B is referred to as the 3rd CSP server.

Step 202, the first UCD server are according to the information of the 3rd CSP server and the size information of original document Determine the 2nd CSP server for uploading the blocks of files of the original document.

The upload file request response that step 203, the first UCD server are sent to second terminal.

Step 204, second terminal upload original document to UCD server.

Step 205, the first UCD server divides original document, i.e., to original document piecemeal.

After the completion of file upload, the first UCD server is according to the information of the 2nd determining CSP server, to original text Part carries out piecemeal, and generates the information of original document, such as the Metadata of original document, and the information preservation of original document is existed At first UCD server.

As an example, the information of the 3rd CSP server includes that the user services in the 3rd CSP The size for the maximum file that the free memory of device and the 3rd CSP server are supported;

It is described to be determined according to the information of the 3rd CSP server and the size information of original document for uploading original text 2nd CSP server of the blocks of files of part specifically: determine that the free memory is greater than the size of the original document, and The 3rd CSP server that the size for the maximum file that the 3rd CSP server is supported is greater than the size of the original document is made For the 2nd CSP server for uploading blocks of files;It is described that blocks of files is uploaded to the 2nd CSP server specifically: will Original document is uploaded to the 2nd CSP server as blocks of files;Or, the information according to the 3rd CSP server And the size information of original document determines the 2nd CSP server for uploading the blocks of files of the original document specifically: really Determine at least two threeth CSPs service of the free memory greater than the size for the maximum file that the 3rd CSP server is supported Device is supported as the 2nd CSP server for uploading blocks of files according to determining at least two the 2nd CSP server The original document is divided at least two blocks of files by the size of maximum file, and by least two blocks of files respectively on At least two the 2nd CSP server is passed to, the size of the blocks of files is less than the maximum that the 2nd CSP server is supported The size of file.

For example, in the present embodiment, the first UCD server determines three CSP server (i.e. thirds that user's registration is crossed CSP server) in CSP server A and CSP server as storage file block the 2nd CSP server, then by original document Few two blocks of files are divided into, the size of each file is less than the size of the maximum file of the support of CSP server A or is less than The size for the maximum file that CSP server B is supported.Certainly, UCD can also divide original document according to other strategies Block, the embodiment of the present invention is it is not limited here.

Further, the information of UCD server storage original document may include: to store the information of the original document, The information of the original document includes: the mark of original document, the divided file number of blocks of original document and each blocks of files File block identification, and storage each blocks of files the 2nd CSP server mark and each blocks of files original Order in file.

Optionally, the information of the original document of the first UCD server storage can also include the size and original of original document The time that beginning file is modified.It is worth noting that original document refers to that second end is serviced to the first UCD in the embodiment of the present invention The file that device is sent.

Specifically, the information of original document is as shown in table 1:

The information of 1 original document of table

Each file block message ChunkInfo for including in the information of original document includes: that file block identification (can unique identification The mark of blocks of files), the CSP information (title of such as CSP or the address of CSP) of storage file block and blocks of files be in original document In order.Further, file block message can also be comprising file block size and other file block messages, such as blocks of files The embodiment of the present invention such as title are it is not limited here.In addition, to file block identification, if the first UCD server is not to original File carries out piecemeal, and file block identification is also possible to the mark of original document.Specifically, file block message can be as shown in table 2:

Table 2, file block message

UCD server generates the information of blocks of files for each blocks of files according to the information of the original document Chunkdata.Specifically, the information of blocks of files includes: file block identification, blocks of files source are (as sent blocks of files to the of CSP The information of one UCD server), the mark of original document belonging to blocks of files.Further, the information of blocks of files can also include Blocks of files marker, to indicate whether blocks of files or original document after dividing.Wherein, the information of blocks of files includes Information is as shown in table 3:

The information of 3 blocks of files of table

It as an example, is original document when UCD server passes to the 2nd CSP server, i.e. UCD is not to original When beginning file block, blocks of files is identified as the mark of original document, and blocks of files marker value is 0.When UCD server passes to When 2nd CSP server is the blocks of files after segmentation: blocks of files marker value is 1

Step 206 or 206 ', the first UCD server is by uploading block request server UploadChunkRequest to the Two CSP server up transfer file blocks, wherein described upload blocks of files of the block request comprising the original document, the first UCD Server generate file block message and the user the first CSP server registration information.

Specifically, the first UCD server is serviced according to the CSP server identification in the information of original document to the 2nd CSP Device uploads blocks of files.Further, it uploads and also carries user in block request in the account name of the 2nd CSP server registration and close Code.

After step 207 or the 207 ', the 2nd CSP server have received blocks of files and the corresponding Chunkdata data of blocks of files, The first UCD server is verified according to the account name and password that upload in block request, and after being verified described in storage Blocks of files, and by the file block message and the user the first CSP server registration information mapping storage, And server is returned to UCD server and uploads block response server UploadChunkResponse message.

When UCD server has sent different blocks of files and Chunkdata data to the 2nd different CSP servers, and After receiving all corresponding return confirmation messages, confirm that the different blocks of files of original document have been stored difference The 2nd CSP server at.

As another optional way, the first UCD server first passes through user and exists before executing step 206 or 206 The account information of CSP server registration establishes the connection with the 2nd CSP server, is then sent out by the connection to CSP server It serves and passes block and request above transmitting file block, so that the 2nd CSP server stores the blocks of files, and by the file block message And the user returns to server upload in the registration information mapping storage of the first CSP server, and to UCD server Block response server UploadChunkResponse message.

As an example, it is assumed that terminal needs the storage file in CSP server :/home/test/A, referred to as original File A.It is sent by UCD client to the first UCD server and uploads file request message, in the upload file request message Carry and user be in UCD server original document ,/home/test/A, size information.First UCD server is receiving end After holding the upload file request message sent by UCD client, is inquired and used in the account name of UCD server registration according to user The information of the 3rd registered CSP server of family.In this example, the user is respectively in CSP server A, CSP server B and CSP server C is registered, then the includes CSP server A, CSP server B and CSP server C in CSP server.UCD The information of the 3rd CSP server that server inquiry user's registration is crossed specifically: respectively to CSP server A, CSP server B and CSP server C sends user's available resources inquiry request, and user's available resources inquiry request carries the first UCD server Account name and password of the user of middle storage in the CSP server registration.First UCD server receives CSP server A, CSP clothes The response that respectively returns of business device B and CSP server C includes: user's available storage in the CSP server in the response The maximum file size that space, CSP server are supported is further, can also include connection speed in the response.First UCD clothes Device be engaged according to the description in step 202, such as according to the information of the CSP server of acquisition and the size information of original document, really Surely the CSP of upper transmitting file determines the 2nd CSP server.Assuming that the first UCD server is determined original text in the present embodiment Part ,/home/test/A, piecemeal storage to CSP server A, CSP server B and CSP server C.Then the 2nd CSP server packet Server A containing CSP, CSP server B and CSP server C.Then, UCD server transmitting file in UCD Client transmission is asked Response is asked, UCD Client is allowed to upload original document/home/test/A.Pass through in UCD client receiving user terminal After original document/home/test/A of biography, step 205 is executed, after original document/home/test/A piecemeal, and passes through step Blocks of files A1-A3 after piecemeal is sent respectively to CSP server A, CSP server B and CSP server C by rapid 206-207.

In another embodiment, it is assumed that the user also needs to upload original document/home/test/B, referred to as original text Part B.And the first UCD server is according to the size of original document B, and the information of each CSP server got, selects CSP clothes Device A be engaged in as the 2nd CSP server and stores the original document, block is not carried out to original document B.

The original document A and original document B that user is uploaded by UCD client by the first UCD server are serviced in CSP The storage schematic diagram of device is as shown in Figure 3: as shown in figure 3, original document A is divided into blocks of files A1-A3 via the first UCD server Afterwards, CSP server A, CSP server B and CSP server C are respectively stored into.And original document B is via the first UCD server CSP server A is stored.

Fig. 4 is CSP server provided in an embodiment of the present invention after user is logged in by terminal, provides service for terminal In the process, the flow chart that terminal acquisition user is stored in each CSP server file information includes the following steps:

Step 400, first terminal log in CSP server B in the registration information of CSP server B by user, and receive During CSP server B provides service, file query requests QueryRequest is sent to CSP server B, checks user In the file information of CSP server B storage.

It is worth noting that the terminal in this process can be the terminal comprising UCD client, it is also possible to not include The terminal of UCD client.For convenience of description, the terminal for connecting CSP server is known as first terminal by the present embodiment.By The CSP server of one terminal connection is known as the first CSP server.

Step 401 obtains the user described the in the registration information of the first CSP server according to the user The file block message of one CSP server storage;

Specifically, each file that CSP server B is stored according to user in the registration information inquiry user of CSP server B Whether corresponding Chunkdata data include original document segmentation mark;

When in Chunkdata information not comprising original document divide identify, as ChunkBit be 0 when, show The corresponding file content of Chunkdata information is complete file, then directly executes step 406.When Chunkdata information includes original When beginning file division mark such as ChunkBit is 1, show that the corresponding file content of Chunkdata information is a certain file Blocks of files then obtains the mark according to the UCD server in the Source information in Chunkdata information (as sent file Block to CSP server B the first UCD server mark, such as the address of the first UCD server) and blocks of files as described in original The mark of beginning file, and execute step 402.

Step 402 sends blocks of files inquiry request to the first UCD server according to the mark of the first UCD server QueryChunkRequest, the mark comprising original document belonging to the blocks of files in the blocks of files inquiry request.

Step 403, the first UCD server obtain the storage of the first UCD server according to the mark of the original document received Original document information.The information of original document includes: the title of original document, the mark of original document and the first UCD clothes The mark and the divided file number of blocks of original document of business device.Optionally, the original document that the first UCD server stores Information can also include the size of original document and the time that original document is modified.First UCD server simultaneously passes through blocks of files The information Metadata information of original document is sent to the server of CSP B by inquiry response QueryChunkResponse.

The mark of the title of the original document and the original document is sent to the first terminal by step 404, and Store the information of the original document of the return;Or the information of the original document is sent to the first terminal.

Alternatively, CSP server B can also generate unified according to the information of the original document received View, and the information of original document is sent to terminal in the form of unified view.

Certainly, the CSP in this process do not have to inquiry ChunkData information in ChunkBit information, but according to Source information in Chunkdata directly obtains the information of original document from UCD server.

As an example, it is assumed that first terminal, which logs on to, sends inquiry request to CSP server A after CSP server A QueryRequest such as can click inquiry button at the interface that CSP server provides.Specifically, user terminal is serviced to CSP It is the prior art that device A, which sends inquiry request, and this will not be detailed here for the embodiment of the present invention.CSP server A is believed according to the registration of user Breath obtains the file block message that CSP server A is stored with the file A1, B of the user such as the account name of user.And pass through storage File A1 information obtain the corresponding Chunkdata of A1 ChunkBit be 1, that is, determine the blocks of files marker be it is original File division mark shows that A1 is to the blocks of files after original document segmentation.CSP server A is according to the letter of the file A1 of storage Breath obtains the mark of original document belonging to the mark and blocks of files for uploading the first UCD server, and passes through the first clothes The mark of business deviceHttp:// ucd server .com/cloudstorageBlocks of files inquiry request is sent to the first UCD server. Wherein, blocks of files inquiry request carries the mark MetadataID:df345gf56 of original document.UCD server is receiving file After block inquiry request, according to the mark MetadataID:df345gf56 of the original document of carrying, obtain corresponding with df345gf56 Metadata information, and the information of Metadata (Filename, ModifiedTime, Size, ChunkNum) is returned to CSP server A.In addition, CSP server A further obtains the information of file B also according to the account name of user, and obtain file B File block message in ChunkBit be 0, it is determined that CSP server storage file B be original document.CSP server root Unified view is generated according to the information of the original document A of acquisition and the file block message of original document B, is supplied to terminal.

Specifically, in the present embodiment, Fig. 5 is stored in the CSP server for the user that CSP server is supplied to user File schematic diagram.As shown in figure 5, be divided into two parts, the listed files information directly uploaded by CSP, and pass through the The file information that one UCD server uploads, the file information for passing through the upload of the first UCD server includes: original document Title, the mark of original document and the first UCD server identification (such as the first UCD server address).It further, if should User leads to multiple first UCD server up transfer file, then can individually list for each first UCD server.Herein no longer It is described in detail.Alternatively, CSP can not also inquire text before obtaining the information of the original document of file of storage ChunkBit information in the information of part block, but directly serviced according to the information of blocks of files source Source to corresponding UCD Device requests Metadata information.

Fig. 6 is the method flow diagram of the file provided in an embodiment of the present invention for obtaining and being uploaded by UCD server, such as Fig. 6 It is shown comprising the steps of:

Step 600, first terminal log in CSP server B by the account information registered in CSP server B, and obtain use Family is stored in the information of the file of the CSP server, after Fig. 5, sends file download request to CSP server B.The file The mark of original document and the title of/original document are carried in downloading request.Further, it can also be wrapped in file download request The information such as the mark and original document modification time of number of blocks containing file (ChunkNum information) and/or the first UCD server.

Step 601, CSP server B determine the corresponding original text of mark of the original document according to the mark of original document Whether part is divided into blocks of files.

Specifically, if contain blocks of files quantity information in file download request, and file number of blocks is less than or equal to 1 When, show that the corresponding original document of the mark of original document is not divided into blocks of files, user can be by terminal directly under CSP Load file corresponding with the mark of original document, and the step of no longer executing below.Alternatively, if under file It carries in request and contains blocks of files quantity information, and when file number of blocks is greater than 1, can be further included in file download request The mark of first UCD server, and execute step 602.

As another optional way, CSP server B according to the original document mark obtain storage with the original The information of the corresponding original document of mark of beginning file, the information of the original document includes: the mark of original document and first The divided file number of blocks of the mark and original document of UCD server;The first CSP server determines the original text The divided file number of blocks of part is greater than 1, and the mark of the first UCD server is obtained from the information of the original document Know.Then step 602. is executed

Step 602 is asked according to the mark of the first UCD server to the first UCD server transmission file acquisition It asks, the file acquisition request carries the mark of the original document.The file acquisition request is used to indicate the first UCD Server obtains the information of the original document of storage according to the mark of the original document, and according to the information of the original document The mark of 2nd CSP server of middle storage file block, from the 2nd CSP service of the mark instruction of the 2nd CSP server Device obtains blocks of files, and the blocks of files of the acquisition is synthesized original document.

Further, the first UCD server obtains according to the mark of the original document received and is stored in UCD server Original document information, the information of the original document includes the mark of the 2nd CSP server of storage file block, second Order of the file block identification and the blocks of files of CSP server storage in original document.

Step 603 or step 603 ', according to the mark of the 2nd CSP server, taken to the 2nd CSP of storage file block Device transmission blocks of files of being engaged in downloads request, carries ChunkID in blocks of files downloading request.

Step 604 or step 604 ', after the 2nd CSP server receives blocks of files downloading request, sent out to the first UCD server Blocks of files corresponding with ChunkID is sent, and sends blocks of files downloading response to the first UCD server.

Alternatively, blocks of files can be sent to the first UCD server in blocks of files downloading response carrying.

Step 605, the first UCD server are according to the blocks of files obtained from the 2nd CSP server in original text Each blocks of files obtained from the 2nd CSP server is merged into the original document by the order in part.

By sending file acquisition response to CSP server B, the file acquisition is rung for step 606, the first UCD server Carrying is answered to position storage address of the file (i.e. original document) on the first UCD server after merging, such as unified resource Symbol: Uniform Resource Locator, URL.

Step 607, CSP server send file download response to terminal, are carried after merging in the file download response Storage address of the file (i.e. original document) on the first UCD server.

Step 608, terminal obtain file from the first UCD server by the URL.

It is worth noting that: the original text that the first UCD server can also in step 606 directly merge step 605 Part is sent to CSP server B, in order to which original document is sent to terminal in step 607 by CSP server B.To not hold Row step 608.

As an example, after terminal logs on to CSP server B by the account information registered, according to the signal of acquisition Figure, user click the corresponding download button " Download " of file/home/test/A, send file download to CSP server A Request.Original document/home/test/A mark and/or file number of blocks are carried in request in the file download request (ChunkNum information).This CSP server B is determined greater than 1, CSP server B since file laxative remedy carries the ChunkNum in request The file of storage is blocked file, then according to the mark for the first UCD server for including in file download request, to http: // Ucd server .com/cloudstorage sends file acquisition request.Carry original document A's in the file acquisition request Identify MetadataID:df345gf56.UCD server can get the corresponding with df345gf56 former of storage according to MetadataID The information of beginning file.UCD server determines that original document A is divided into 3 files according to the information of the original document of storage Block is respectively stored in CSP server A, CSP server B, CSP server C, then according to the ChunkID of each blocks of files, to right The CSP server answered sends blocks of files downloading request, to download blocks of files A1, A2, A3 from these three CSP respectively.It is receiving Blocks of files A1, A2, A3, correspond to order information according to each blocks of files, these three blocks of files are merged into original document.Further according to The storage location of complete file after merging generates download link, is sent to CSP server A, and be transmitted to by CSP server A Terminal.Terminal directly downloads file according to link, can be obtained file/home/test/A.
