Content disclosed by book is understood other advantages and efficacy of the present invention easily, it is clear that described embodiment is the present invention one
Section Example, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not doing
Every other embodiment obtained under the premise of creative work out, shall fall within the protection scope of the present invention.
The embodiment of the present invention 1 provides a kind of document transmission method, specifically as shown in Figure 1, this method is executed by server,
Include the following steps:
Step 110, user is received to instruct by the fragment that client is sent.
It requests specifically, user passes through client input file first, after server receives file request, calls related
File.User can determine network speed information and file size.If network speed is lower than preset threshold, and file committed memory
It is very big.So, transmission will necessarily be slow, be easy to cause network congestion.At this point, user can send one point by client
Piece instruction, fragment instruction are exactly to be used to indicate server to carry out fragment processing to file to be transmitted, then pass through at least two
Transmission paths transmission.And to again may be by user customized for the quantity of specific transmission path.It is of course also possible to be system
Transmission path quantity is set according to by fragment treated subfile quantity, it is specific to execute operation and sets according to the actual situation
It is fixed, it does not do excessively be limited in a specific example here, include: a server and client side at least two transmission paths
Between the direct transmission path established；And the indirect communication established between at least one client, network node and server
Path.Specifically as shown in figure 3, Fig. 3 illustrates the document transmission system structural schematic diagram comprising at least two transmission paths.
Step 120, it is instructed according to fragment, according to pre-established fragment rule, file to be transmitted is subjected to fragment processing,
Obtain at least two subfiles.
Specifically, fragment rule is mainly to specify the committed memory size of each subfile, such as each subfile is maximum
10M is inside saved as, a file to be transmitted is 96M, then this file to be transmitted will be divided into 10 subfiles, 9 subfiles
It is 10M, a subfile is 6M.Usually executing as preceding 9 subfiles is 10M, the last one subfile is 6M.But it is practical
In, being also possible to first subfile is 6M, and rear 9 files are 10M, or an intermediate subfile is 6M, other
Subfile is 10M.Specific fragment rule can be customized according to the actual situation, here with no restrictions.
Step 130, identification information corresponding with each subfile is set.
Specifically, client can recombinate all subfiles after being transmitted to client for the ease of subfile,
Complete file to be transmitted is constituted, can be corresponded to after carrying out fragment processing to file to be transmitted for the setting of each subfile
Identification information.For example, being numbered for each subfile, first subfile serial number 1, second subfile serial number
2, and so on.At that time, client can be ranked up and recombinate to subfile according to numeric order.
Step 140, all subfiles and identification information corresponding with each subfile are assigned at least two biographies
Defeated path, to be transmitted separately to client.
Specifically, after file to be transmitted carries out fragment processing and the corresponding identification information of setting, so that it may be transmitted
?.In practical implementation, subfile and corresponding identification information can be packing and transmitted together.Guarantee between the two
Connection it is close, without entanglement between file and identification information.It is not each transmission path average mark when transmitting file
Subfile, but parallel transmission subfile simultaneously.If some transmission path prioritised transmission finishes a subfile, press
One subfile of the transmission path is distributed in the subfile that sequence is never transmitted to continue to transmit.So, realize that " energy person is more
Labor ".Transmission path file rate is comparatively faster will to transmit file more, be further ensured that file transfer rate.And client
End can recombinate all subfiles according to identification information after receiving all subfiles, constitute whole file.
Optionally, can be before subfile be transmitted in order to guarantee the safety in document transmission process, subfile
It is encrypted after being packaged with identification information.
It is further alternative, in order to which client is after receiving subfile, the integrality of subfile can be verified, it can be with
Before subfile is transmitted, the MD5 value of each subfile is calculated, by the MD5 value of subfile, with subfile and Ziwen
The corresponding identification information of part is packaged together, is even encrypted after packing, is then forwarded to client.
Optionally, in the above method, since client can own after defaulting preset time period receiving the file moment
File reception is completed.Then file is recombinated according to identification information.Determine that file has missing in regrouping process as crossed, then
The transmission of file can be continued waiting for, perhaps sends whether feedback information confirmation subfile does not distribute or lose to server
The subsequent operations such as mistake.Specific operational means is all the prior art, does not do excessive introduction here.
And in order to client can the more accurate file of stator really whether receive, this method can also include:
The relevant informations such as subfile transmission before, the quantity of memory, subfile that file to be transmitted is occupied, each
The memory and information corresponding at least two transmission paths that subfile occupies are sent to client.At least two transmission paths
Corresponding information can be to which transmission path is client explanation use, such as comprising each at least two transmission paths
The corresponding identification information of a transmission path, such client are also apparent that through which interface and interface pair
The subfile for the transmission path answered.
By this kind of mode, client is after receiving file, so that it may oneself determine whether file receives.If
It receives, then all subfiles is recombinated according to identification information again.Certainly, if encrypted to subfile
Words are decrypted after then recombinating.If further including the MD5 value of subfile in the information of transmission, each Ziwen can be first verified
Then the integrality of part is recombinated again, is decrypted.Specific operating procedure can flexibly be set according to the actual situation, not done here
