Embodiment
The method of a kind of multimedia file shared system provided by the present invention and shared multimedia file thereof, for making object of the present invention, technical scheme and advantage clearly, clearly, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
A kind of multimedia file shared system that the embodiment of the present invention provides, as shown in Figure 1, comprise server and some use terminals (use terminal A as shown in Figure 1, use terminal B, use terminal C ...), wherein, described server comprises user management module, index management module and propagation management module, also arranges in addition and is used for the buddy list of storing subscriber information and the index file for storing multimedia.Described use terminal can be the smart machines such as personal computer, palmtop PC, mobile phone, also can be the electronic equipment for consumption that is main purpose with audio-visual amusement, such as player, game machine and all-in-one etc., use at each dedicated memory terminal set up and has for storing multimedia.
Described user management module, is used for the maintenance being responsible for buddy list on the one hand, and is stored by the new friend information using terminal to add, and being used on the other hand provides query interface to use terminal inquiry buddy list info; For example, after user with the addition of new good friend by UI interface, friend information stores by this user management module, when other software modules need inquiry buddy list info, also be the api interface being provided inquiry by this module, the friend information of user is directly maintained in server end but not client.
Described index management module, be used on the one hand managing the concordance list of multimedia file, often complete the transmission of a multimedia file block, Real-Time Monitoring upgrades the index information on concordance list corresponding to this multimedia file block; The renewal of the index information of concordance list comprises: to the cryptographic Hash of multimedia file block, the IP using terminal and multimedia file block in the renewal using the concrete memory location in terminal.
Wherein, index management module is nucleus module, and in the present invention, the corresponding independent concordance list of each multimedia file is stored in the index file of server, and index management module is exactly the module of the concordance list in index file being carried out to operational administrative.
Complete after a complete multimedia file block downloads whenever using terminal, use terminal will send an index upgrade message to index management module, index upgrade message will comprise following critical field content: (binary value of random length is mapped as the less binary value of regular length to the cryptographic Hash of multimedia file block by hash algorithm, this little binary value is called cryptographic Hash), use the IP of terminal, multimedia file block is using the concrete memory location in terminal.
Index management module is after receiving message, upgrade the index file that this multimedia video frequency file is corresponding, in this way, after multimedia file BOB(beginning of block) spreads through the internet and comes, often using in terminal at one downloads successfully, will increase by is corresponding in indexed file record, by this way, the blocks of files distribution of the overall situation on index file real-time servicing the Internet, this is also the data basis that propagation management module does decision-making judgement.
Described propagation management module is used for when using terminal to need upload multimedia file on the one hand, receive the concordance list of the multimedia file that user uploads, and control to use terminal to be published to by multimedia file block in the multiple different use terminal on its buddy list several times in advance in the mode being similar to virus propagation; Be used for when the scope of release monitoring multimedia file block reaches set point on the other hand, control to use terminal to stop the issue of blocks of files.
The propagation management module of embodiment of the present invention server is the decision-making module in whole scheme, mainly bears two pieces work: the propagation of scheduling multimedia file block, and controls the excessive propagation of multimedia file block at suitable time point.
For example, first propagation management module by user management module, inquires the friend information of user, locates the use terminal of these good friends, send instructions to the issue needing the use terminal of upload multimedia file to carry out file subsequently from buddy list; After user uses terminal to receive instruction, first set up network with the online use terminal enlivening good friend to be connected, some multimedia file blocks are selected subsequently the random multimedia file concordance list from establishing before, the data of the multimedia file block these selected send to equally by the use terminal of random choose good friend out, these all operations are all carry out on backstage, because the data volume of blocks of files itself is also little, so whole transfer of data can not have an impact to other operations of user.
When multimedia file block is propagated complete, after index is updated, propagation management module in server is by the index information of concordance list in search index file, can be appreciated that now same multimedia file block has been distributed on different equipment, propagation management module can after a period of time, (object done like this alleviates facility load, avoid data transfer operation too frequently), use terminal to new good friend sends multimedia file block issuing command, the buddy list of the use terminal searching oneself of this new good friend, again repeat aforesaid operating process.
An other critical function of propagation management module controls to propagate, when the use terminal having the blocks of files of this multimedia file in propagation management module monitors to the concordance list at certain multimedia file reaches a predetermined quantity (such as 500 or 1000), stop the propagation of this multimedia file, namely no longer to using terminal to send the instruction of issuing this multimedia file associated documents block.As a rule, when simultaneously online and the use terminal having a blocks of files of multimedia file reaches 500-1000 time be just enough to provide good upload and download service.
Particularly, the propagation parameter that propagation management module installation one is propagated for stopping multimedia file, stops the propagation of this multimedia file when the use terminal of the blocks of files having certain multimedia file reaches the quantity of propagation parameter setting.Because the scale of number of users exists larger impact to the propagation of multimedia file, difference between a use terminal network only having the use terminal network of about 10,000 users and to have about 1,000,000 users is very large, therefore, this propagation parameter dynamically can adjust according to network size, when network size is larger, this propagation parameter can respective settings obtain larger, so that it is faster to make Spreading and diffusion obtain.
As shown in Figure 2, described use terminal comprises transmission module and blocks of files download module in friend information administration module, piecemeal module, reserved area administration module, blocks of files.
Wherein, described friend information administration module for the operation receiving user carry out user's registration and good friend inquiry, add, delete management; For example carry out user's registration and good friend's inquiry, interpolation, deletion etc. by friend information administration module.
Piecemeal module is used for carrying out piecemeal to the multimedia file that need upload by the partitioned mode of fixed size, this multimedia file is formally divided into the multimedia file block that some sizes are identical, and calculate cryptographic Hash corresponding to each multimedia file block, and create for the concordance list after this multimedia file piecemeal, and this concordance list is uploaded onto the server; For example for the scene of upload file, piecemeal module is once cut (not needing actual cutting whole into sections) by the partitioned mode of fixed size by the file uploaded, and corresponding cryptographic Hash is calculated to each blocks of files, then construct an initial concordance list, and this concordance list is uploaded to the index management module of server.In another embodiment, piecemeal module can also adopt pro rata partitioned mode or carry out piecemeal according to the partitioned mode of other related algorithms to the multimedia file that need upload.
Reserved area administration module for setting up the dedicated memory of storing multimedia data and managing this dedicated memory, as depicted in figs. 1 and 2.For example, by reserved area administration module set up special storage area and dedicated memory, and this dedicated memory is managed, such as, detect the size of reserved area remaining space, deleted file block and merge file block etc.
In blocks of files, transmission module is used for the multimedia file block issuing command of reception server, the multimedia file block of correspondence is sent to the use terminal of multiple good friend selected by server end; By transmission module in blocks of files, some multimedia file blocks are sent in the use terminal of multiple good friend selected by server end.
Blocks of files download module for receiving the blocks of files of download instruction downloading multimedia file, and by download blocks of files stored in dedicated memory;
For example, for the scene of automatic download file block, after receiving the download instruction from propagation management module, download corresponding multimedia file block by blocks of files download module, and by it stored in the dedicated memory of marking specially;
For another example, for the scene by using the whole multimedia file of terminal downloads, after reception user downloads the instruction of multimedia video frequency file, then pass through multimedia file block download module with the All Files block of the mode downloading video files of P2P, and be combined into a multimedia video frequency file.
Based on the multimedia file shared system of above-described embodiment, the embodiment of the present invention additionally provides a kind of method that multimedia file shared system shares multimedia file, and as shown in Figure 3, described method mainly comprises the following steps:
Step S100, by use terminal receive user input operational order set up buddy list.
Wherein, this step S100 specifically comprises when implementing: A1, the user login information using terminal to be inputted by user interface reception user, and sends this user login information to server; A2, when described user login information obtains after server authentication passes through, the interface menu of the interpolation good friend using terminal to be provided by it obtains friend information from described server, and is loaded in local buddy list by the friend information of acquisition.
For example, first user when first time uses use terminal of the present invention, the title being inputted oneself by a simple user interface (UI) is registered, and the log-on message of user can upload in the carrier server of network and verify by this interface program.
Can normally log in after being verified, by a special query interface, can inquire about the information of its good friend from this server after user logs in, and join in local buddy list, buddy list directly passes through name identification.What good friend showed user is title, and what be associated with this title is the IP address of user, and just this IP address is sightless for user, is the ID of unique identification user for software.
Step S200, using dedicated memory terminal set up and is used for storing multimedia data; And piecemeal is carried out to the multimedia file that need upload become multiple multimedia file block, and create for the concordance list after this multimedia file piecemeal, and the concordance list of this multimedia file is uploaded onto the server.
For example, in embodiments of the present invention, the use terminal of user constantly can be added new friend information and be entered in this buddy list, when each start or shutdown, use terminal in real time to the up-to-date upper down status of server update self, the last state of every good friend in buddy list can be inquired about simultaneously.
Current use terminal is substantially all built-in memory devices such as hard disk, need hard disk to mark one piece of special dedicated memory, be used for storing the data such as multimedia used, this dedicated memory is the bigger the better in theory.
When simultaneously online use terminal quantity is enough large, these are by the use terminal-specific memory block dividing out specially, have just been made into a huge virtual hard disk space, if Fig. 1 is as the virtual memory space shown by group of networks.
Wherein, piecemeal carried out to the multimedia file that need upload become multiple multimedia file block in this step S200, and create for the concordance list after this multimedia file piecemeal, the concordance list of this multimedia file is uploaded onto the server and comprises the following steps in the specific implementation:
B1, use terminal carry out piecemeal to the multimedia file that this locality that need upload stores by the partitioned mode of fixed size, this multimedia file is formally divided into the multimedia file block that some sizes are identical, and calculates cryptographic Hash corresponding to each multimedia file block;
B2, the cryptographic Hash corresponding according to each multimedia file block calculated, create the concordance list of corresponding multimedia file, the index information content of concordance list comprises the cryptographic Hash of each multimedia file block of this multimedia file, and the IP address of use terminal residing for this multimedia file, and the memory location of this multimedia file block in this use terminal;
The concordance list of the multimedia file of establishment uploads onto the server by B3, use terminal.
Such as when user needs to carry out uploading of multimedia file (as video file), the embodiment of the present invention has been no longer uploaded by whole video file in fact, but first utilize piecemeal module once to cut (not needing actual cutting whole into sections) by the partitioned mode of fixed size local video file, it is divided in form the multimedia file block that some sizes are identical, and each multimedia file block is calculated to the cryptographic Hash of its correspondence, then a concordance list for this video file is constructed, the index information content of concordance list is the cryptographic Hash of each piece of this multimedia file, the IP address of the use terminal residing for this block, and the memory location of this block on this use terminal equipment.
Under initial situation, content in this concordance list, especially IP address and memory location is all be positioned at the local information used in terminal, when this concordance list is uploaded to after on server, upload procedure just ends, operation directly can return to user and control, and with this mode of operation, whole upload procedure can terminate within the very short time, because be uploaded to the concordance list of just this video file of server, instead of video file itself.Effectively can reduce configuration and the maintenance cost of server like this.
Step S300, server receive the concordance list of this multimedia file, and control this use terminal and multimedia file block is published in advance in the multiple different use terminal on its buddy list in the mode being similar to virus and propagating, and often complete the transmission of a multimedia file block, server Real-Time Monitoring upgrades the index on concordance list corresponding to this multimedia file block; When the scope of release monitoring multimedia file block reaches set point, control to use terminal to stop the issue of blocks of files;
This step S300 comprises in the specific implementation:
C1, server receive and the concordance list of storing multimedia, after server receives concordance list, the friend information of meeting inquiring user from the buddy list of the use terminal of this multimedia file of storage, and locate the use terminal of these good friends, multimedia file block issuing command is sent subsequently to the use terminal storing this multimedia file, notify that this use terminal can carry out the issue of multimedia file, enter step C2.
C2, store this multimedia file the multimedia file block issuing command of use terminal reception server after, according to the instruction of server several times, the use terminal of each initiatively online with part good friend is set up network and is connected;
C3, use terminal are selected some multimedia file blocks according to the concordance list of described multimedia file at every turn, and the data of the multimedia file block selected are sent to the use terminal establishing the good friend that network connects.
After server receives index in the present embodiment, the buddy list in terminal being used according to user, locate the use terminal of these good friends, sending instructions subsequently to storing the use terminal of this multimedia file to carry out the issue of file.
After user uses terminal to receive the instruction of server, initiatively use terminal first to set up network with online active good friend to be connected, from the File Index Table established before, select some multimedia file blocks, the data of these multimedia file blocks being sent to is that the select good friend of serviced device uses terminal equally at every turn.Particularly, the use terminal of server controls upload file divides the multimedia file block at every turn selecting 1/m for m time, is sent to the use terminal of the good friend of 1/n by transmission module in blocks of files, and this use terminal is presence.Here m and n can be such as 10, this represents that the blocks of files at every turn choosing 10% sends to the good friend of 10%, exclude blocks of files and the good friend of selected mistake when selecting, this user uses terminal by the way whole multimedia file block to be sent to gradually the use terminal of different good friend.Share agreement according to the relevant of default, these all operations are all carry out on backstage, because the data volume of the multimedia file block after piecemeal itself is also little, so whole transfer of data can not have an impact to other operations of user.When good friend is not enough, the propagation of blocks of files stops, until there is new good friend to add, now propagation can restart until stop.
By this way, the use terminal of user is under connection state, set up network with the several use terminals in buddy list to be connected simultaneously, and transmit specific multimedia file blocks of data, be just stored in after the multimedia file blocks of data received of the use terminal of good friend in advance on hard disk by that dedicated memory of marking.
Often complete the transmission of a multimedia file block, server Real-Time Monitoring upgrades the index on concordance list corresponding to this multimedia file block.Namely, after a complete multimedia file block completes transmission, corresponding concordance list on index file in update server at once, for this multimedia file block, now same cryptographic Hash is by multiple for correspondence different IP value and multiple different memory location.
After index is updated, server has been distributed to multiple different use terminal equipment on to the monitoring consciousness of concordance list to now same multimedia file block by index management module, server can after a period of time, use terminal simultaneously to new good friend sends multimedia file block issuing command, the use terminal of this new good friend can search for the buddy list of oneself, and the multimedia file block received sends in the use terminal of the good friend of the 1/n of oneself again.
In the mode in the multiple different use terminal using terminal to be published to by multimedia file block on its buddy list in advance in the mode being similar to virus and propagating by server controls of the present invention, multimedia file block can on backstage promptly with good friend, the good friend of good friend, this mode of good friend of the good friend of good friend, spread, a same multimedia file block can automatically be distributed in multiple use terminal equipment, the propagation being similar to virus-type is carried out according to buddy list, and propagate at every turn, all by concordance list corresponding for this file on renewal server.Now, if the other side returns the insufficient space of its dedicated memory, then stop transmitting blocks of files in the use terminal of this good friend.
Meanwhile, server real-time servicing and Analytical Index table in the invention process, when there being the use terminal of abundant user distributed enough blocks of files of certain multimedia file, server just can stop above-mentioned propagation.Particularly, server Real-Time Monitoring and Analytical Index table, when the blocks of files of certain video file leaves 500 use terminals in time, because this quantity has been enough to provide good download service, server no longer sends the instruction of this video file of issue to using terminal accordingly, thus stops propagating.
The instruction of the download multimedia file of step S400, use terminal receiving target user input, adopts this multimedia file of P2P mode downloading and playing according to the concordance list of this multimedia file that need download.
Wherein, this targeted customer refers to the user expecting to play or directly download certain multimedia file, it performs the operation of user by using corresponding software program interface in terminal, multimedia file herein refers to the multimedia file having had concordance list in the server, by above-mentioned software program interface, user can know which multimedia file (specifically referring to the concordance list of this multimedia file) is used terminals to upload onto the server by other and middlely to download for user.This step S400 comprises at specific embodiment:
D1, when targeted customer need play or download certain multimedia file time, download concordance list corresponding to this multimedia file from server;
D2, use terminal, according to the information of the index file of concordance list, obtain the blocks of files of this multimedia file one by one;
D3, when certain blocks of files is present in multiple use terminal, to be connected with the plurality of use terminal simultaneously, to send request of data, download this multimedia file data from multiple source simultaneously.
For example, when targeted customer will play or directly download certain video file, directly download index corresponding to this video file from server, user uses terminal according to the information of index file, carry out download to each blocks of files one by one by blocks of files download module to obtain, now, if this video file is through propagating in advance, then same file block is not only present in the use terminal of former uploader, and is present in other by the use terminal that is propagated through.When certain blocks of files is present in multiple use terminal, the use terminal of targeted customer is connected with this multiple use terminal simultaneously, send request of data, by this way, traditional once can only from the pattern of a source downloading data, and becoming once can from downloading data while of multiple source, and the speed of whole download can improve several times, no matter be download or play, whole speed can be strengthened greatly.
Based on above-described embodiment, multimedia file shared system of the present invention, as shown in Figure 4, its propagation management module specifically comprises:
