Embodiment
The embodiment of the invention provides the method for shared file in a kind of group, and shared file is pushed to group interior other user terminal, to increase the resource of point-to-point download, improves speed of download, reduces taking of server bandwidth.
As shown in Figure 1, the flow process of propelling movement shared file comprises:
Step S101, user terminal are shared group's file according to user's indication;
Whether step S102, determination strategy server receive the first propelling movement order and the shared shared file information of this user terminal that user terminal sends, if, execution in step S103, if not, process ends;
The information of the shared file that step S103, strategic server share this user terminal is pushed to other user terminals in the group;
Step S104, user terminal obtain each online in group user terminal information after receiving information from strategic server, and online user terminal downloads to shared file in the buffer memory by point-to-point mode from group.
Like this, promptly realized the propelling movement of group's shared file, when terminal is downloaded this shared file according to user's download command, to in the document indexing server of storage file information, select to download equally by the shared file tabulation, but after selecting to download, at first whether user terminal can store the shared file that the user will download in the query caching, if have, then the burst of this shared file is directly copied to from buffer memory in the specified path of user and get final product, if the shared file of storage is imperfect, after then copying to the burst of storing in the buffer memory in the specified path, also need to download by point-to-point mode other bursts of shared file from online user terminal, if the shared file that does not have the user to download in the buffer memory is then directly downloaded the download path of whole bursts of shared file to appointment from online user terminal by point-to-point mode.
In step S102, during the user terminal uploads shared file, the download situation of the historical shared file of this user in the meeting file index server, when the download situation of the historical shared file of this user satisfies condition, send the information of the shared file that pushes instruction and uploaded, wherein, the download situation of this user's historical shared file can be the first average download rate of user's historical shared file, perhaps second of the historical shared file of the affiliated classification of this shared file of the user average download rate, the file that the user uploaded is every to be downloaded once through group member, just adds up the download situation of this user institute shared file again.For example: certain user shared 10 files altogether in group, 4 is the music class, 6 is video class, the download rate of each file is that the number of times that is downloaded of this document is divided by the number of members in this group, the average download rate that the condition that pushes can be set at 10 files surpasses a threshold value, for example can threshold value be set to 60%, the average download rate that also can be the class file under the file of newly uploading surpasses a threshold value, for example, the file of newly uploading is a video, judge then whether the average download rate of 6 videos once uploading surpasses the threshold value of regulation, can also both judge whether the first average download rate surpasses the threshold value of regulation, judge again whether the second average download rate surpasses the threshold value of regulation, when the two all satisfies, push the file of newly uploading again, certainly, except that above-mentioned several determination methods, can also carry out different settings according to different needs.
In step S103, strategic server is pushed to each user terminal with the information of shared file, at this moment, some user terminal may not reached the standard grade, can safeguard that pushes a tabulation by strategic server, information that record is pushed and the corresponding user terminal that does not also push, in case finding has user terminal to reach the standard grade, then search and push in the tabulation whether the shared file information that will be pushed to this user terminal is arranged, if have, push this shared file information and give this user, simultaneously with the deletion from push tabulation of this user terminal.
During user's shared file, can be as the information and the file content of upload file in the prior art, the information of file comprises file name, type, size, source etc., if file has burst, also need upload the size of burst quantity and each burst, can be provided with according to the situation and the needs of reality.
Further, when the file that will share is big, upload the inconvenience that big file brings to the user for eliminating the user, the user also can send the order of only upload file information, make user terminal only with the information uploading of file in document indexing server, and not upload file, other user terminals are downloaded by the user of point-to-point mode from the user that downloaded this document or shared this document.
Further, for preventing that the user from uploading excessive shared file and making troubles for the user, prevent that simultaneously file content server stores pressure and bandwidth pressure are excessive, the limits value that the user uploads the shared file size can be set in user terminal, as be set to 300M, then when uploading, the user can upload the shared file less than 300M, if the shared file that the user will upload is greater than 300M, then do not upload the content of shared file, only with the information uploading of shared file to document indexing server, and prompting user, the file of uploading is excessive, in not uploading onto the server.
In step S104, at a user terminal when other user terminals carry out point-to-point download, also from the file content server, download, flow for further control documents content server, alleviate bandwidth pressure, can control the flow when the file content server is downloaded, the threshold value of a speed of download further can be set, when other user terminals when point-to-point download and speed of download do not reach predefined threshold value, again from the file content server file in download of storage file content.
For further improving the speed of downloading, when user terminal is downloaded, the online situation that can periodically inquire about each user terminal to strategic server, and when having new user terminal to reach the standard grade, foundation is connected with this user terminal, after determining to store required shared file burst in this user terminal, carry out point-to-point download.
The point-to-point downloading mode that the embodiment of the invention adopted is: because when upload file, desire downloaded files and carried out burst according to the big young pathbreaker of file, and identify for each burst, the size of each burst can be 128K or 256K, 512K, 1M etc., minimum burst can be set to 128K, the size of minimum burst also can be set according to actual conditions, when file is big, each burst is also bigger, general each big file all will divide burst more than 10 to guarantee speed of download, for file, then do not need to carry out burst less than minimum burst.So when downloading, the burst situation of file in download at first, get in touch each online user's terminal again, inquire about the storage condition of this shared file in each user terminal, promptly inquire about which burst is all arranged in each user terminal according to the sign of each burst, the inquiry back is according to the storage condition of each user terminal, from different user terminals, download different bursts simultaneously, to guarantee speed of download, when online user's terminal less, or this shared file burst of storing in online user's terminal is less, can not reach comparatively ideal speed of download, then downloads the part burst from the file content server.
Further, each burst can be provided with independently check code, when mistake appears in downloaded files, as long as download the burst of makeing mistakes again, does not need to carry out again a large amount of downloads like this.
When downloading the file that is pushed, for not influencing user's normal use, the speed of download can be regulated at any time according to the situation that takies of user bandwidth.
Buffer memory in the user terminal is that unit divides with minimum burst size generally, when being 128K as minimum burst, the unit of buffer memory also is 128K, each burst that downloads to like this in the buffer memory all takies one or more buffer units, each buffer unit has " using " and " not using " two states, when the burst in the buffer memory is downloaded number of times and is less than setting in a period of time, just the buffer unit setting state that this burst is taken, is not labeled as " using " to download new shared file burst again for " using " after the download.The shared file of downloading when desire is bigger, and when being marked with the insufficient space that has used in the buffer memory, then downloads the part burst of shared file at random.
Further, for satisfying user's different demands, user-friendly, the user can select active push simultaneously after shared file, promptly send active push order indication, the information of the file that user terminal then can be shared according to user's transmission active push order indication transmission second propelling movement order and user is to strategic server, strategic server receives second of user terminal transmission and pushes when ordering, the information of second shared file that the user shared is pushed to other user terminals as selectable shared file information, after other user terminal receives the selectable shared file information of strategic server propelling movement, optionally connected receipts or refusal, when selecting to receive, will select download path simultaneously, during download, be to download shared file from online user terminal in the path of appointment by point-to-point mode equally.
The embodiment of the invention also provides the system of shared file in a kind of group, as shown in Figure 2, comprising:
