Embodiment
The embodiment of the present application provides a kind of file fragmentation transmission method and device, with file division is the subclass file that is adapted at transmission under the multithreading, described subclass file is transmitted simultaneously, assemble then, to reach the purpose of effectively utilizing the system CPU resource.
More than be the application's core concept, understand the application's scheme better in order to make those skilled in the art person.Below in conjunction with the accompanying drawing in the embodiment of the present application, the technical scheme in the embodiment of the present application is clearly and completely described, obviously, described embodiment only is the application's part embodiment, rather than whole embodiment.Based on the embodiment among the application, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all should belong to the scope of the application's protection.
The flow chart of the file fragmentation transmission method that the embodiment of the present application provides comprises as shown in Figure 1:
Step S101: obtain the file that client need be uploaded;
Step S102: above-mentioned file is divided into the fragment file of specifying size;
Step S103: start multithreading with non-obstruction form with above-mentioned fragment file transfer to CPU.
Need to prove:
In the process of transfer files, for specifying the fragment file of size, burst transmits with file division, and the size of each fragment file is no more than 1MB, when transmission, starts multithreading and carries out the transmission of each fragment file with non-obstruction form.Fully effectively utilized the computing capability of multi-core CPU.
In the cutting procedure to file, partition principle is the content according to file, and the content of file inside is carried out segment processing, guarantees the continuity of the content in every segment file, guarantees that the size of file is no more than 1MB when guaranteeing continuity.If the content of file surpasses 1MB on the basis of continuity, then can carry out once more burst and obtain sub-burst content the file that surpasses 1MB, on the file of sub-burst, increase sign, the mode of being docile and obedient preface is transmitted by sign, after receiving sub-slicing files, make up by sign antithetical phrase slicing files; If the sub-slicing files of sequential delivery, the sub-slicing files transmission of front sends failure, then according to its sign, in this complete burst, hold other all sub-burst contents that identify burst and all be in wait state, after the sub-slicing files of bust this resends, make up with other the sub-burst content that is in wait again.
Wherein, take place just to operate in the reality Action Events in the IO operation but non-obstruction is middle CPU, can not lose time and wait for the generation of IO incident, improved the utilance of CPU, Chuan Shu process is a parallel transmission simultaneously, has improved transmitting speed.
One detailed flow chart of the document transmission method that the embodiment of the present application provides for flow process shown in Figure 1, also comprises step S112 as shown in Figure 2 between step S102 and step S103: be the described fragment file allocation check code of specifying size that is divided into.
For the main purpose of fragment file allocation check code is that CPU can utilize checking procedure after the fragment file is sent to CPU, the orderly fragment file to receiving makes up, to obtain the whole file in the transmission course.
The another detail flowchart of the file fragmentation transmission method that the embodiment of the present application provides comprises that also step S104:CPU makes up described fragment file as shown in Figure 3; In conjunction with the process flow diagram that CPU shown in Figure 4 makes up the fragment file, CPU to the detailed process that the fragment file makes up is:
Step S201: request check code;
Step S202: the check code of request and the check code in the fragment file of reception are carried out verification;
Step S203: check results is judged, if verification succeeds, execution in step S204; Otherwise execution in step S205;
Step S204: the fragment file is write official document;
Step S205: illustrate that this fragment file occurs unusually in transmission course, abandon the fragment file of this verification failure, return that S103 transmits this fragment file again in the whole step.
For example: system is in the transfer files process, with the fragment file of file division for the appointment size, size is 512K, be check code of each fragment file allocation, after dividing well, start a plurality of threads, each CPU distributes 5, simultaneously the fragment file is outwards sent, because network transmission lag time ratio is bigger, so the free time that is sending, system can utilize CPU that next fragment file is carried out the Hash verification, after the recipient receives the fragment file, can ask a Hash check code equally, the fragment that receives is carried out verification, if verification succeeds writes the fragment file in the official document, otherwise, abandon this fragment file, again this fragment file is transmitted.
The structural representation of the file fragmentation transmitting device that the embodiment of the present application provides comprises as shown in Figure 5: file acquiring unit 301, file division unit 302 and file transfer unit 303;
Described file acquiring unit 301 is used to obtain the file that client need be uploaded;
Described file division unit 302 is used for the file that file acquiring unit 301 obtains is divided into the fragment file of specifying size;
Described transmitting element 303 is used to start the fragment file that multithreading cuts apart file division unit 302 and transfers to CPU with non-obstruction form.
Wherein file division unit 302 is no more than 1MB with the fragmentate size of file of file division.
The non-obstruction form that transmitting element 303 sends the fragment file is CPU carries out valid function when but the reality Action Events takes place in the IO operation.
One detailed structure schematic diagram of the file fragmentation transmitting device that the embodiment of the present application provides as shown in Figure 6, file division unit 302 comprises check code allocation component 304;
Fragment file allocation check code that check code allocation component 304 is cut apart for described file division unit 302 and the described CPU request of response after described CPU receives the fragment file that described transmitting element 303 sends are that described CPU sends the required check code of verification.
Each embodiment in this specification all adopts the mode of going forward one by one to describe, and identical similar part is mutually referring to getting final product between each embodiment, and each embodiment stresses all is difference with other embodiment.The above only is the application's a embodiment; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the application's principle; can also make some improvements and modifications, these improvements and modifications also should be considered as the application's protection range.
