UCD servers, according to the information of the original document, are the information Chunkdata that each blocks of files generates blocks of files.Specifically, the packet of blocks of files contains：File block identification, blocks of files source（Blocks of files is such as sent to the information of CSP the first UCD servers）, the mark of the original document belonging to blocks of files.Further, the information of blocks of files can also include blocks of files flag, to indicate whether blocks of files or original document after segmentation.Wherein, the information that the packet of blocks of files contains is as shown in table 3：

The information of blocks of files

As an example, when UCD servers pass to the 2nd CSP servers for original document, i.e. UCD not to original document piecemeal when, blocks of files is designated the mark of original document, and blocks of files flag value is 0.When UCD servers pass to the 2nd CSP servers for blocks of files after segmentation when：Blocks of files flag value is 1

Step 206 or 206, the first UCD servers are by uploading block request server

UploadChimkRequest is to the 2nd CSP server up transfer file blocks, wherein the log-on message for uploading blocks of files of the block request bag containing the original document, the file block message of the first UCD servers generation and the user in the first CSP servers.

Specifically, the first UCD servers according to the CSP server identifications in the information of original document to the 2nd CSP server up transfer file blocks.Further, upload in block request and also carry account name and password of the user in the 2nd CSP server registrations.

Step 207 or 207,, the 2nd CSP servers have been received after blocks of files and the corresponding Chunkdata data of blocks of files, account name and password according to uploading in block request are verified to the first UCD servers, and the blocks of files is stored after being verified, and store the file block message and the user in the log-on message mapping of the first CSP servers, and return to the good device UploadChimkResponse message of being engaged in of the server upload block response moon to UCD servers.

When UCD servers have sent different blocks of files and Chunkdata data to the 2nd different CSP servers, and receive after all corresponding return confirmation messages, confirm that the different blocks of files of original document have been stored at the 2nd different CSP servers.

It is used as another optional mode, first UCD servers are before step 206 or 206 is performed, first pass through user and set up the connection with the 2nd CSP servers in the account information of CSP server registrations, then sent by the connection to CSP servers and upload block request above transmitting file block, so as to blocks of files described in the 2nd CSP server storages, and store the file block message and the user in the log-on message mapping of the first CSP servers, and return to server upload block response server UploadChunkResponse message to UCD servers.

It is used as an example, it is assumed that terminal needs the storage file in CSP servers：/ home/test/A, Abbreviation original document A.Sent by UCD clients to the first UCD servers and upload file request message, carried in the upload file request message and user is in UCD server original documents ,/home/test/A, size information.First UCD servers are after the upload file request message that terminal is sent by UCD clients is received, the information for the 3rd CSP servers crossed according to user in the account name inquiry user's registration of UCD server registrations.In this example, the user is registered in CSP server As, CSP server Bs and CSP servers C respectively, then the includes CSP server As, CSP server Bs and CSP servers C in CSP servers.The information for the 3rd CSP servers that UCD server lookup user's registrations are crossed is specially：Respectively to CSP server As, CSP server Bs and CSP servers C send user's available resources inquiry request, and user's available resources inquiry request carries the account name and password of the user that is stored in the first UCD servers in the CSP server registrations.First UCD servers receive CSP server As, and the response that CSP server Bs and CSP servers C are each returned is included in the response：User's maximum file size that available memory space, CSP servers are supported in the CSP servers is further, and connection speed can also be included in the response.First UCD servers are according to the description in step 202, such as according to the information and the size information of original document of the CSP servers of acquisition, it is determined that the CSP of upper transmitting file is to determine the 2nd CSP servers.Assuming that in the present embodiment, the first UCD servers are determined original document ,/home/test/A, CSP server As, CSP server Bs and CSP servers C are arrived in piecemeal storage.Then the 2nd CSP servers include CSP server As, CSP server Bs and CSP servers C.Then, UCD servers are sent to UCD Client uploads file request response, it is allowed to which UCD Client upload original document/home/test/A.After original document/home/test/A that user terminal is uploaded by UCD clients is received, perform step 205, after original document/home/test/A piecemeals, and the blocks of files A1-A3 after piecemeal is sent respectively to by CSP server As, CSP server Bs and CSP servers C by step 206-207.

In another embodiment, an ancient weapon made of bamboo user also needs to upload original document/home/test/ B, abbreviation original document 8.And the first UCD servers are according to original document B size, and each CSP servers got information, selection CSP server As do not carry out block as the 2nd CSP server storages original document to original document B. The original document A and original document B that user is uploaded by UCD clients by the first UCD servers are as shown in Figure 3 in the storage schematic diagram of CSP servers：As shown in figure 3, original document A is divided into after blocks of files A1-A3 via the first UCD servers, CSP server As, CSP server Bs and CSP servers C are respectively stored into.And original document B has only stored CSP server As via the first UCD servers.
