Embodiment
With reference to the accompanying drawings the present invention is described more fully, exemplary embodiment of the present invention wherein is described.Exemplary embodiment of the present invention and explanation thereof are used to explain the present invention, but do not constitute improper qualification of the present invention.
With the video file is example, before the method for carrying out teleprocessing file of the present invention, can a plurality of attribute informations on each local video source server be stored into respectively in local database server and the central database server by local WEB server, central WEB server and local video source server.For example, can store by the distributed system shown in Fig. 2.
Fig. 2 is the structural representation of the system of storage file attribute information.
As shown in Figure 2, be that example describes with the video file, but the present invention is not limited to video file, can also be applicable to other forms of data file, for example, dat file or pst file.This distributed system 20 comprises TRACKER server 21, central database server 22, central WEB server 23, a plurality of local WEB server 24, a plurality of local database server 25 and a plurality of local video source server 26.
Wherein, local video source server 26 is used to deposit the video file of uploading, and generate TL (Telecast automatically, radio and television) file, this TL file comprises the information such as IP address that video is deposited path, video name, video size, video code flow, MD5 (Message Digest version 5, eap-message digest 5) sign indicating number and local video source server.Wherein, the MD5 sign indicating number is a global unique identification symbol that is produced at random by the local video source server, and it can be unique cryptographic Hash of f750f1a8a233ccb23ef1a524a5675a8c for example, is used for identifying uniquely this video file.
If the transmission marker position that local WEB server 24 is judged in the local database server 25 is 0, so local WEB server 24 sends request signal to central WEB server 23 and sends data with request, will send the marker position after this signal is sent completely and be set at 1.
The WEB of central authorities server 23 receives the request signal of each local WEB server 24, and the IP address of storing the local WEB server 24 that comprises in this request signal.
Whether the WEB of central authorities server 23 inquiry central database servers 22 are busy, if central database server 22 is busy, then central WEB server 23 enters this request signal in its waiting list; If central database server 22 is not busy, then central database server 22 connects local database server 25, and judge whether the transmission Data Labels position in the local database server 25 is 0, wherein, send the Data Labels position and be used for judging whether the relevant information of this video sent, if be 1 to represent the relevant information of this video to send, if be 0 to represent the relevant information of this video not send, the default value that sends the Data Labels position is 0.
It should be noted that, central database server 22 has been initiated the long-range connection to local database server 25, rather than local database server 25 initiated the long-range connection to central database server 22, guaranteed the fail safe of central database server 22 like this.
If the transmission Data Labels position that central database server 22 is judged in the local database server 25 is 0, then central database server 22 reads the data of this local database server 25, specifically be exactly, read the attribute information relevant (promptly with each local video file, the TL file), read and send the Data Labels position after finishing and be set to 1.
Central authorities' WEB server 23 sends to central database server 22 with the IP address of the corresponding local WEB server 24 stored, and the attribute information (TL file) that the IP address of the corresponding local WEB server 24 that central database server 22 will receive is relevant with the video file that is read is stored explicitly.
TRACKER server 21 reads the relevant attribute information of video file from central database server 22,, reads the information in the TL file that is, and the issue of distributed video has so far been finished in 21 pairs of video registrations of TRACKER server.At this moment, stored on the local database server 25 with local video source server 26 on the relevant attribute information (TL file) of video file of storage, in the IP address of the local WEB server 24 of having stored the attribute information (a plurality of TL file) relevant on the central database server 22 and being associated with it with the video file stored on all local video source servers 26.
After this, when client will be watched video, client links to each other with TRACKER server 21, TRACKER server 21 provides the IP address information of local video source server 26 nearest or that network condition is best to client, and after this client and this local video source server 26 carry out real video flowing transmission.
Need to prove in the entire process process, to have only local video source server 26 to store real video file, the data message on other servers all is the attribute information relevant with each local video file.
After central WEB server etc. has been stored the relevant attribute information of video file, can handle the video file that is stored on the local video source server according to teleprocessing file system provided by the invention.
Fig. 3 is the structural representation of first embodiment of system of the present invention.
