For let the object of the invention, characteristic, and advantage can be more obviously understandable, hereinafter is special lifts preferred embodiment, and cooperates Fig. 3 to Fig. 5, does detailed explanation.
The method flow diagram of Fig. 3 for quickening file transfer according to the present invention.The present invention belongs to the invention of application layer (Application Layer) in the network osi model (Open System Interconnection ReferenceModel) in order to transmit a plurality of files at intercomputer.In Fig. 3 step S301, method of the present invention provides a plurality of file group, and is example so that three file groups to be provided in the present embodiment, comprise one first file group, one second file group and one the 3rd file group, yet the present invention is not as limit.In step S302; Judge the characteristic of described file; And in the extremely described file of the property sort group according to described file; And the characteristic of described file comprises the size of described file and the type of this document, and the type of wherein said file then can be judged according to the extension name of this document, states after seeing for details.
The mode classification of step S302 sees also the 2nd hurdle among Fig. 4 in the present embodiment; Wherein, This first file group is the set that file size surpasses a particular value file; This particular value is 700MB in present embodiment, is to comprise promptly that with this step the All Files size is classified in this first file group above 700MB person in the described file that tendency to develop is defeated.Moreover this second file group is that file size does not surpass this particular value, and its compression ratio is less than the set of the file of a certain compression.The ratio of the file size after this compression ratio is defined as the preceding file size of compression and compresses:
Compression ratio=(file size before the compression)/(file size after the compression);
And this certain compression is 1.4 in present embodiment; And the extension name of this document promptly can be used as the foundation of its compression ratio; For example, expansion jpg person by name changes very few (compression ratio is much smaller than 1.4) with compressed software commonly used such as WinRAR compression back file size, be with; The jpg shelves are one to have the file type of low compression ratio, and document classification is as shown in Figure 5.Step S302 comprises that again the All Files size is classified in this second file group less than 1.4 above 700MB and compression ratio in the described file that tendency to develop is defeated.At last, the 3rd file group is that file size does not surpass the set that this particular value and compression ratio surpass the file of this certain compression.Likewise; Compression ratio is with above-mentioned definition, and the extension name of this document promptly can be used as the foundation of its compression ratio, for example; Expansion txt person by name changes very huge (compression ratio far surpasses 1.4) with compressed software commonly used such as WinRAR compression back file size; Be to be one to have the file type of high compression ratio with, txt shelves, document classification is as shown in Figure 5.Step S302 comprises that more the All Files size is classified in the 3rd file group above 1.4 above 700MB and compression ratio in the described file that tendency to develop is defeated.
The present invention takes a package processing mode of corresponding this document group respectively to described file group in step S303.In the present embodiment, to one first package processing mode that should the first file group for described file not being encapsulated (packing) or compression (compressing).In the present embodiment, one second package processing mode that should the second file group for the described file in this second file group is encapsulated in a plurality of packages, but is not compressed described file.In the present embodiment, to one the 3rd package processing mode that should the 3rd file group for the described File Compress in the 3rd file group and be encapsulated into a plurality of packages.At last, method of the present invention is transmitted the described file under this document group in step S304.
It should be noted that; Adopt the reason of this first package processing mode to be this first file group last being set forth among the step S303; File in this first file group is big; Added burden between file (overhead) relative file itself comes much for a short time, and it is encapsulated or compresses on the contrary and come consuming timely with respect to direct transmission.And adopt the reason of this second package processing mode to be this second file group among the step S303; File compression rate in this second file group too small (promptly the file size after the compression is still big); To its compress and after decompress spent temporal summation with its encapsulation back transmit time of being consumed many, be needn't it being compressed.Yet, adopt the reason of the 3rd package processing mode to be the 3rd file group among the step S303, the file compression rate in the 3rd file group is big, is worth earlier it being compressed again transmitting.
Method according to prior art experimentizes, and the result is shown in following table ().Wherein the total size of file of transmission is all 11.8GB (9922 of number of files) in each experiment, and its included a plurality of files have various file types.This experiment is transmitted file in experiment 1 respectively totally one by one; In experiment 2, file is encapsulated the back transmission totally, and after transmission, give decapsulation again; And in experiment 3, file being encapsulated and the transmission of compression back totally, and decapsulation and decompression again after transmitting.Can find that from experiment in experiment 1, it need not encapsulate and compression time, is 1 hour 38 minutes 24 seconds but always expend time in, for the longest among the three.Experiment 3 is the action of experiment 2 increase compressed file cases relatively, is to have long encapsulation and compression time, equally also to have long decapsulation and decompression time.
Come again, according to embodiments of the invention, file is classified to each file group after, with the method for corresponding this document group file is transmitted respectively again, shown in following table (two).This is tested with above-mentioned experiment, the file content of transmission identical (the total big or small 11.8GB of file, 9922 of numbers).Therefore the experiment of prior art is adopted in contrast, and the present invention always expends time in and is merely 0 hour 34 minutes 18 seconds, can find that the present invention can save the file transfer time really.
