As shown in figure 3, being applied to MAG, the embodiment of the present invention the embodiment of the invention provides another document handling method
In by taking file A as an example, the processing method of alternative document be referred to file A processing method processing, this method comprises:
The file A that step 301, interception client are sent.Execute step 302.
When client needs to access server, client firstly generates the file A for demand file data, and to clothes
It is engaged in can wrap the IP address containing server in device transmission file A, file A, after MAG detects file A, file A can be cut
It takes, server is prevented to receive file A.
Step 302 establishes connection with client.Execute step 303.
Exemplary, after intercepting file A, MAG can be generated the IP address of virtual server, and by the virtual server
IP address is sent to client, and MAG and client is made to establish connection.
Step 303, detect MAG upstream Interface whether congestion.If so, executing step 305.If it is not, executing step 304.
Specifically, MAG can with the data of real-time detection MAG upstream Interface transmit in lost data packet number with it is transmitted
The quantity of data packet calculates the ratio of the quantity of lost data packet number and transmitted data packet in data transmission, obtains net
Packet loss in the transmission of road judges the upstream Interface congestion of MAG when the packet loss in network transmission is greater than default packet loss；
When packet loss is less than or equal to default packet loss in network, the upstream Interface of MAG not congestion is judged.The default packet loss can be with
It is 10%, which must be worth or other numerical value, and it is not limited in the embodiment of the present invention.
Step 304 downloads the corresponding file data of file A by MAG.Execute step 311.
Exemplary, MAG can send file A to server, and server is corresponding by file A according to the file information of file A
File data be sent to MAG, complete the downloading of the corresponding file data of file A.
Whether step 305, detection file A are big file.If so, executing step 306.If it is not, executing step 304.
It should be noted that the data volume of file A can be compared with the first data value, if the data volume of file A
Greater than first data value, then judge file A for big file；If the data volume of file A is less than or equal to first data value,
Judge file A for small documents.First data volume is exemplary for distinguishing big file and small documents, which can be with
For 10M (million), the value of first data volume may be other values, and it is not limited in the embodiment of the present invention.Specifically, when text
Part A be small documents when, need to judge the type of file A, if the data value of the corresponding file data of file A is relatively small, as html,
The file data of the types such as php, js, thens follow the steps 304, if the data value of the corresponding file data of file A is relatively large, such as
The file data of the types such as apk, mp4 then needs during executing step 304 to the biography of the corresponding file data of file A
Defeated rate is limited, it is preferred that the transmission rate that can limit the corresponding file data of file A is no more than 128Kbps (bit
Rate).
File A is divided into the multiple small documents successively arranged by step 306.Execute step 307.
Exemplary, when detecting the upstream Interface congestion of MAG, i.e., packet loss is greater than default packet loss in current network,
File A is then divided into the multiple small documents successively arranged according to the second data value.It should be noted that the big file is file
Data volume be greater than the first data value file.Further, should be divided into according to the second data value successively arrange it is multiple small
In file, the data volume of each small documents is less than or equal to the second data value, and second data value is less than or equal to the first number
According to value.Since second data value is less than or equal to the first data value, so that the data of multiple small documents after big file division
Amount is less than or equal to the first data value, i.e., without big file in the file transmitted in the upstream Interface of MAG after segmentation.
Specifically, multiple small texts when the data volume of the big file is the integral multiple of second data value, after the segmentation
The data volume of each small documents in part is equal to the second data value.For example, when the data volume of the big file is 100M, second number
It is 1M according to value, at this point, the data volume of the big file is the integral multiple of second data value, it can be the big of 100M by the data value
File division is the small documents that 100 data values successively arranged are 1M, i.e., in 100 small documents after the big file segmentation
Each small documents data volume be equal to 1M.When the data volume of the big file is not the integral multiple of second data value, this point
Multiple small texts in multiple small documents after cutting other than the data volume of a small documents is less than the second data value, after other segmentations
The data volume of part is equal to the second data value.For example, second data value is 3M when the data volume of the big file is 100M, at this point,
The data volume of the big file is not the integral multiple of second data value, can be by the data value 100M big file division be according to
34 small documents of secondary arrangement, which is respectively the small documents that 33 data values are 3M and a data value is 1M's
Small documents.In 34 small documents i.e. after the segmentation other than the data volume of a small documents is less than 3M, other 33 segmentations
The data volume of small documents afterwards is equal to 3M.
Step 307 establishes listed files a.Execute step 308.
It successively arranges specifically, being divided into the file A that data volume is greater than the first data value according to the second data value
After multiple small documents, MAG need to establish listed files a, and the file that listed files a is used to record the multiple small documents successively arranged is suitable
Sequence.It is assumed that the data volume of file A is 100M, it is assumed that the second data value is 1M at this time, is 100M by the data value
File A the small documents that 100 data values successively arranging are 1M are divided into according to the second data value, respectively No. 1 file is extremely
No. 100 files.At this point, listed files a need to be established, the numerical value in this document list B is successively arranged, and the corresponding segmentation of each numerical value
A small documents in file A afterwards, as shown in figure 4, exemplary, the file A after the corresponding segmentation of numerical value 1 in listed files a
In No. 1 file, No. 2 files in the file A after the corresponding segmentation of numerical value 2 in listed files a, the numerical value n in listed files a
The n file in file A after corresponding segmentation.
It should be noted that the document order of multiple small documents can also by multiple small documents mark and index into
Row instruction, specifically, after file A is divided into multiple small documents by step 306, it can be small for each of multiple small documents
Then file allocation identification and index establish the file of the mark and index for recording multiple small documents in step 307
List, it is 100M's by the data value that it is assumed that the data volume of file A is 100M, the second data value, which is 1M, at this time
File A is divided into the small documents that 100 data values are 1M, respectively No. 1 file to No. 100 files according to the second data value.Show
Example, the mark of No. 1 file can be that the index of 1, No. 1 file can be 0~1M, and the mark of No. 2 files can be 2, No. 2 texts
The index of part can be 1~2M, and the mark of No. 3 files can be that the index of 3, No. 3 files can be 2~3M.
Step 308, the corresponding file data of the multiple small documents of downloading.Execute step 309.
Specifically, as shown in figure 5, step 308 may include:
It whether there is adjacent equipment in step 3081, the preset range of MAG detection MAG.If so, executing step 3083.If
It is no, execute step 3082.
Exemplary, MAG can detecte in surrounding's preset range of MAG with the presence or absence of nearby device, it should be noted that should
Preset range can be 3m (rice), and the value of the preset range may be other values, and it is not limited in the embodiment of the present invention.It should
Nearby device can be the network access device of platform, or the MAG on other vehicles.
Step 3082 downloads the corresponding file data of multiple small documents by MAG.
It should be noted that when adjacent equipment is not present in the preset range of MAG, after being divided by MAG to file A
Multiple small documents are downloaded.MAG can send multiple small documents to server, and server is according to the texts of multiple small documents
The corresponding file data of multiple small documents is sent to MAG by part information, completes the downloading of the file data of multiple small documents.
Multiple small documents are divided into two groups of files, respectively a group of file and second group of file by step 3083, MAG.
Execute step 3084.
Specifically, if there are an adjacent equipments in the preset range of MAG, it is multiple small after file A being divided
File is divided into a group of file and second group of file, and the corresponding file data of multiple small documents after this document A segmentation is by first
The group corresponding file data of file and the corresponding file data composition of second group of file.The a group of file is downloaded by MAG, this
Two groups of files are downloaded by nearby device.It should be noted that when detect in the preset range of MAG there are multiple nearby devices,
The multiple small documents that file A can be divided are again divided into multiple groups file, wherein the group number of the file after division is equal to
The number of nearby device adds 1, and exemplary, 2 adjacent equipments, then the group number of the file after dividing are 3 if it exists.It is above-mentioned multiple small
The corresponding file data of file can be made of the corresponding file data of multiple groups file, appoint a group of file in the multiple groups file
It can be downloaded by MAG, other group of file is downloaded by multiple nearby devices respectively.Exist when in the preset range of MAG
Multiple nearby devices, the document transmission method of each nearby device can there are a neighbours in the preset range with reference to above-mentioned MAG
The document transmission method of nearly equipment, the embodiment of the present invention do not repeat them here this.
Exemplary, the ratio of the quantity of documents of a group of file and second group of file can be 1 or a group of file
Quantity of documents and second group of file quantity ratio can less than 1, the quantity of documents of a group of file with this second group
The sum of quantity of documents of file is the quantity of documents of multiple small documents after this document A segmentation, it should be noted that this first group
The ratio of the quantity of documents of the quantity of documents of file and second group of file may be other values, and the embodiment of the present invention does not do this
It limits.Preferably, when adjacent equipment existing in the preset range for detect MAG be platform on network access device, due to
The network bandwidth of the network access device of platform is greater than the network bandwidth of MAG, the i.e. speed of the network access device network of the platform
Rate is greater than the rate of MAG network, so the ratio of the quantity of the quantity of documents of a group of file and second group of file is less than 1,
That is quantity of documents of the quantity of documents of a group of file less than second group of file.
Step 3084 downloads the corresponding file data of a group of file by MAG, downloads second group of text by adjacent equipment
The corresponding file data of part.
Preferably, MAG can send a group of file to server, and server is believed according to the file of a group of file
The corresponding file data of a group of file is sent to MAG by breath, completes the downloading of the file data of a group of file.
Wherein, as shown in fig. 6, downloading the corresponding file data of second group of file by adjacent equipment, may include:
Step 30841, MAG send solicited message to adjacent equipment.Execute step 30842.
It should be noted that setting in the preset range for detecting MAG there are after adjacent equipment, MAG can be closed on to this
Preparation send solicited message, which is used to request the upstream interface state information of adjacent equipment, upstream interface state letter
Breath can be congestion and non-congestion.
