A kind of file synchronisation method, referring to fig. 4, method flow provided in this embodiment includes:
401, the first seed file that destination server is provided according to source server synchronizes specified text in first network
Part.
Wherein, including at least all information of specified file and first network information etc. in the first seed file.In this reality
It applies in example, specified file is to need synchronous file, and all information of specified file includes the size of specified file, specified file
Fragment rule, the total characteristic value of specified file, each fragment data of specified file and the characteristic value of each fragment data etc.,
The present embodiment does not make specific limit to all information of specified file.First network information include source server IP address,
The IP address etc. of each destination server.
Since the information for including in the first seed file is the key that destination server synchronizes specified file, in mesh
Before marking server sync specified file, need first to obtain the first seed file.The first Ziwen is obtained about destination server
The mode of part, including but not limited to the following two kinds mode:
First way, destination server obtain the first seed file from source server.
Currently used method can be used in complete file resource based on storage, source server, such as raw using BT software
At the second link information and the first seed file.In the present embodiment, the second link information is typically small, usual tens words
Section only includes specified file cryptographic Hash, source server address, may be connected to the first net according to the second link information destination server
In network, the first seed file is much larger than the second link information.Be unfavorable for Internet communication, for improve seed file propagation rate,
Second link information can be sent to each target clothes after generating the second link information and the first seed file by source server
Business device, so as to be connected to after destination server receives the second link information that source server is sent according to the second link information
First network, and then the first subfile is downloaded from source server.
The second way, destination server obtain the first seed file from other servers in first network.
After other servers in first network get the first seed file from source server, destination server
The first seed file that can be got from the server of other in first network.
After getting the first seed file, the first seed file that destination server is provided according to source server, In
In first network when synchronous specified file, including but not limited to: in the synchronizing process to any of specified file fragment data
In, judge the first synchronous duration of fragment data whether more than the first preset duration；If the first synchronous duration is more than first default
Duration, and the first synchronous number of attempt reaches the first preset times, then the server currently synchronized is switched to the first net
Other servers continue to execute synchronizing process in network.
Wherein, the first synchronous duration can be connected to the Connection Time on current sync server for destination server,
The downloading duration of fragment data can be downloaded from the server currently synchronized for destination server.First preset duration can
Think 1 second, 2 seconds, 3 seconds etc., the present embodiment does not make specific limit to the first preset duration.First preset times be 2 times, 3 times,
4 is inferior, and the present embodiment does not equally make specific limit to the first preset times.
In the synchronizing process to any of specified file fragment data, when to any of specified file fragment data
The first synchronous duration be less than the first preset duration, illustrating can be fully synchronized by the fragment data in this synchronizing process
Get off, can directly synchronize the fragment data at this time.When the first synchronous duration to any of specified file fragment data is more than
First preset duration, illustrates that Network status is bad, destination server synchronizes the speed of the fragment data from current server
Relatively slow, synchronizing process takes a long time, and needs to judge whether the first synchronous number of attempt reaches the first preset times at this time, if first
Synchronous number of attempt is not up to the first preset times, can continue to attempt to synchronize the fragment data on current server at this time；
If the first synchronous number of attempt has reached the first preset times, the server currently synchronized can be switched in first network
Other servers continue to execute synchronizing process.For example, setting server in first network as server A, server B, service
Device C, server D and server E, the first preset duration are 2 seconds, and the first preset times are 3 times, the server currently synchronized
For server A, if the first of synchronous fragment data is 1 second a length of when synchronous, due to first synchronous duration 1 second it is default less than first when
It is 2 seconds long, it can get off at this time by the fragment data is fully synchronized；If the first of synchronous fragment data is 3 seconds a length of when synchronous, first is same
Walking number of attempt is 2 times, then continues to synchronize the fragment data on server；If the synchronous duration of the first of synchronous fragment data
It is 3 seconds, the first synchronous number of attempt is 4 times, then can switch to and synchronize the fragment data on server D.
It should be noted that the process of above-mentioned synchronous specified file is only synchronized with a fragment data to specified file is
Example is illustrated, for specified file other fragment datas synchronizing process referring to synchronizing to said one fragment data
Journey, details are not described herein again.In to specified file synchronizing process, for any one fragment data in specified file, if first
Synchronous duration is more than the first preset duration, and the first synchronous number of attempt is more than the first preset times, requires to carry out current
Synchronous server switches to other servers in first network and continues to execute synchronizing process.
For the ease of subsequently through continuing in the process using specified file, when synchronized out of first network specified file it
Afterwards, specified file is also stored in seeder server by destination server.
402, destination server generates the first link information and second seed file according to specified file.
Wherein, the first link information includes partial information and second network information of specified file etc., and the present embodiment is not right
First link information makees specific limit.The partial information of specified file includes the fragment of the size of specified file, specified file
Rule, the total characteristic value of specified file, each fragment data of specified file and the characteristic value of each fragment data etc., this implementation
Example does not make specific limit to the partial information of specified file.Second seed file includes all information and second of specified file
Network information etc., the second network are the P2P network being made of destination server and multiple client.
About destination server according to specified file, the mode of the first link information and second seed file is generated, including
But it is not limited to: Software Create is generated using seed file, the present embodiment does not limit this specifically.
Since the first link information and second seed file will continue to apply in subsequent client synchronous documents,
Destination server is according to specified file, after generating the first link information and second seed file, the first chain that will additionally generate
Information and the storage of second seed file are connect into the seeder server of destination server.
403, the first link information is sent to each client in the second network by destination server.
Resource consumption in order to realize the shared of file resource, while when reducing synchronous documents, destination server is according to finger
Determine file, after generating the first link information, each client for being also sent to the first link information in the second network.
First link information is sent to the mode of each client in the second network about destination server, including but
Be not limited to: the first link information is sent in the second network by destination server by the way of cable network or wireless network
Each client etc..
404, when the first link information for receiving destination server transmission, client is according to the first link information, from target
Second seed file is downloaded on server.
In order to save Internet resources, in the present embodiment, the moment is not in connection to each client in the second network
State is only receiving link information, and when opening link information, just may be connected in the second network.
Since specified file and second seed file are stored in the seeder server of destination server, when even
It is connected to after the second network, each client can download second of Ziwen from the seeder server of destination server
Part.
405, client is according to second seed file, the synchronous specified file in the second network.
Specifically, client is according to second seed file, the synchronous specified file in the second network, including but not limited to:
In the synchronizing process to any of specified file fragment data, judge that the second synchronous duration of fragment data is
It is no more than the second preset duration；
If the second synchronous duration is more than the second preset duration, and the second synchronous number of attempt reaches the second preset times, then
The destination server currently synchronized or client are switched to other destination servers or client in the second network to continue
Execute synchronizing process.
Wherein, the second synchronous duration can be connected to the Connection Time currently synchronized in equipment for client, can also
Think client from the downloading duration for currently synchronizing downloading fragment data in equipment.Second preset duration can be 2 seconds, 3
Second, 3 seconds etc., the present embodiment do not make specific limit to the second preset duration.Second preset times are 3 times, 6 times, it is 8 inferior, this
Embodiment does not equally make specific limit to the second preset times.
In order to improve the synchronizing speed to specified file, method provided in this embodiment is to any of specified file point
Before sheet data synchronizes, the second preset duration will be also set.When same to the second of any of specified file fragment data
Step duration has been less than the second preset duration, illustrates in this synchronizing process to get off the fragment data is fully synchronized,
The fragment data can be directly synchronized at this time.When the second synchronous duration to any of specified file fragment data has been more than second
Preset duration illustrates that Network status is bad, and the speed that destination server synchronizes the fragment data from current server is slower, together
Step process takes a long time, and needs to judge whether the second synchronous number of attempt reaches the second preset times at this time, if second synchronizes and taste
Examination number is not up to the second preset times, can continue to attempt to synchronize the fragment data on original equipment at this time；If first is synchronous
Number of attempt has reached the first preset times, the destination server currently synchronized or client can be switched to second at this time
Other destination servers or client continue to execute synchronizing process in network, e.g., if the equipment that current sync synchronizes is mesh
Server is marked, then destination server can be switched to other clients in the second network and continue to synchronize the fragment data；If current
Synchronizing the equipment synchronized is client, then destination server can be switched to other clients in the second network and continue to synchronize
The fragment data switches the client currently synchronized if other clients, which do not have, needs synchronous fragment data
Continue to synchronize the fragment data on to the destination server in the second network.
For client according to second seed file, the process of synchronous specified file in the second network below will be with Fig. 5
For be described in detail.
Fig. 5 is the second network being made of a destination server and multiple client (peer), destination server by
Tracker server and seeder server composition.When each client in the second network passes through destination server
Tracker server is connected to after the second network, and each client obtains from the seeder server of destination server
Two seed files, and according to second seed file in the second network synchronize specified file each fragment data.In the second net
In network when each fragment data of synchronous specified file, client can synchronize specified from the seeder server of destination server
The fragment data of file can also also synchronize the fragment data of specified file from other clients.Certainly, in order to improve synchronization
Speed reduces the resource consumption of destination server, when a client synchronizes to get off from server and specifies text in the second network
After the fragment data of part, other clients can preferentially synchronize the fragment data of specified file from the client.
It should be noted that the resource consumption of P2P network is different when due to being communicated using different agreements.
When being communicated using http protocol, since the head character of http protocol is more, the information content for needing to carry is larger, therefore,
Network resource consumption is larger.And in the present embodiment, no matter communication or target clothes between source and target server
It is communicated between business device and client all using udp protocol.After being communicated using udp protocol, not only reduces Internet resources and disappear
Consumption, greatly increases the connection number between client.
