In correlation technique, the abundant while of information also makes network load larger.A solution is to adopt content distributing network (Content Distribution Network, CDN), CDN node is set in network, and a CDN node can be a server farm, shares transmission pressure by the quantity that increases server.But this scheme is larger to the quantity demand of server, has increased equipment cost.Another kind of solution be by terminal as distribution node, terminal is also responsible for uploading data in downloading data.That is to say that terminal can, from end downloading data, alleviate network pressure.But this scheme is a kind of transmission plan of file-level, all data in file must be common data just can adopt this scheme.If the private data that some data in file are user, cannot adopt this scheme.For addressing the above problem, the present embodiment segments the data attribute in file, shares attribute field for each data cell increases.The value of this shared attribute field is common data or private data for flag data unit.If common data, can be near terminal downloads, if private data can be downloaded from server.The present embodiment has been realized the contents distribution of data level, has both improved efficiency of transmission, has ensured again the safety of private data.And because not every data all derive from server, therefore reduce the pressure of server, thereby reduced the demand of number of servers.
Fig. 1 is according to the flow chart of a kind of method of transmitting data shown in an exemplary embodiment, and as shown in Figure 1, the method can be realized by mobile terminal, comprises the following steps:
In step 101, the structured data from server download file.
In step 102, from described structured data, parse the value of the shared attribute field of each data cell in described file.
In one embodiment, the value of the shared attribute field of data cell can be configured by user or data content provider.Also configuration automatically after can identifying by means such as semantic analyses.For example, the data of news content are common data, and the data in individual subscriber cyberspace are private data etc.
In step 103, in the time that the value of shared attribute field that has data cell is common value, in WLAN (wireless local area network), broadcast the first mark of the data cell that common value is corresponding.
In step 104, receive the response for described broadcast that in WLAN (wireless local area network), terminal sends.
In step 105, from send the terminal of described response, download the data cell that common value is corresponding.
The present embodiment has been realized the contents distribution of data level, and the different pieces of information unit in a file can be downloaded from distinct device.Can download near end for the data cell that common value is corresponding, alleviate the pressure of the webserver, save number of servers.And multi-source is downloaded can improve download efficiency.
The general act that file in the present embodiment can be made up of multiple subfiles, a data cell can be a subfile.Structured data is structured file, and for example the file of .xml form is structured file.
Taking web page news as example, terminal may need to download the file that multiple webpages form, and has many news in each webpage, and every news may comprise news picture and news content.News picture or news item content are a data cell.News picture is a subfile.
For example, it is " Today's news " that terminal 1 needs the data of downloading, and " Today's news " comprise 5 news, and every news includes news picture and news content, altogether 10 data cells.First terminal 1 downloads the structured data of " Today's news " from server, known and had 10 data cells by analytic structure data, can also obtain the first mark of each data cell and the value of shared attribute field.For example, the example of one first mark is: http-cache: //www.xxx1.com/yy1, this mark is as example, can also adopt the mark of other form taking URL (unified resource location), is all applicable to the present embodiment.Wherein " cache " represents that the value of shared attribute field is common value, if do not comprise " cache ", that is to say that shared attribute field is default, be worth for sky, the value that represents shared attribute field is privately owned value, and for example the example of one first mark is: http://www.xxx1.com/yy1.
Then terminal 1 can be broadcasted the first mark of the data cell that common value is corresponding in WLAN (wireless local area network).For example 10 data cells are common data, and terminal 1 can be broadcasted 10 data cells first and identifies, as broadcast the first mark 1-first and identify 10.In the present embodiment, WLAN (wireless local area network) comprises the network that various short-distance wireless connect and compose, short-distance wireless connect as: infrared connection, bluetooth connect, WiFi connects, NFC connects etc.
For example in WLAN (wireless local area network), also has terminal 2-terminal 5.Terminal 2-terminal 5 receives that obtaining the first mark 1-first after broadcast identifies 10, checks the local data cell that whether has the first mark 1-first and identify 10 correspondences.For example terminal 2 has the first mark 1-first and identifies 3, and terminal 4 has the first mark 3-first and identifies 7, and terminal 3 and terminal 5 do not have the first mark 1-first and identify the data cell of 10 correspondences.Terminal 2 and terminal 4 send response to terminal 1, and the response of terminal 2 comprises that the first mark 1-first identifies 3, and the response of terminal 4 comprises that the first mark 3-first identifies 7.Then terminal 1 can be downloaded the first mark 1-first from terminal 2 and identify the data cell of 3 correspondences, and downloads the first mark 3-first from terminal 4 and identify 7 data cell.For the data cell of the first mark 3 correspondences, can respectively download a part from terminal 2 and terminal 4.Identify 10 for the first mark 8-first, can download from server.
In one embodiment, may have multiple websites to report for same news, may there be different names different websites to same news, that is to say that same news may have multiple marks.If can obtain multiple marks of same news, can expand the scope of Data Source, further improve download efficiency.Therefore can be referring to option A.
Option A:
Described response comprises the second mark of described data cell.
After step 104, described method also comprises: steps A 1 and steps A 2.
In steps A 1, in WLAN (wireless local area network), again broadcast the second mark of the data cell that common value is corresponding.
In steps A 2, again receive that terminal in WLAN (wireless local area network) sends for the described response of broadcast again.
In the present embodiment, in step 104 and steps A 2, all can receive response, can be for response downloading data unit from corresponding terminal in step 104 and steps A 2 in step 105.
Continue example above, website xxx1 and website xxx2 have all reported " Today's news ", and news is identical, and 10 data cells are all identical, but are the mark difference of 10 data cell locations.Website xxx1 is that the first mark 1-first that is designated of 10 data cell locations identifies 10, and website xxx2 is that the second mark 1-second that is designated of 10 data cell locations identifies 10.Corresponding the first mark 1 of first data cell and the second mark 1, by that analogy.First mark 1 as: http-cache: //www.xxx1.com/yy1, second mark 1 as: http-cache: //www.xxx2.com/yy1.
Terminal 1 has been downloaded the structured data of " Today's news " from the server of website xxx1, know that the first mark 1-first identifies 10, and the value of the shared attribute field of 10 data cells is common value.Terminal 1 is broadcasted the first mark 1-first and is identified 10 in WLAN (wireless local area network).Terminal 2 checks that there is the first mark 1-first this locality and identifies 3 data cell, and the local record that also has data cell 1 corresponding the second mark 1.The response that terminal 2 sends comprises that the first mark 1-first identifies 3, and comprises the corresponding relation of the first mark 1 and the second mark 1.
Terminal 1 is received after response, again in WLAN (wireless local area network), broadcasts, and the content of broadcast is the second mark 1.Now terminal 5 checks the local data cell 1 that has the second mark 1 correspondence, and sends response to terminal 1, and this response comprises the second mark 1.Terminal 1 can be from terminal 2 and terminal 5 downloading data unit 1.
The Data Source of terminal 1 expands to terminal 2, terminal 4 and terminal 5 from terminal 2 and terminal 4 as can be seen here.Obtain more Data Source by associated identification information, thereby improved download efficiency.
In one embodiment, after terminal downloads data cell, need to store in this locality, in order to reduce repeated storage, can be referring to option b, option b comprises step B1-step B4.
Option b:
In step B1, obtain the fingerprint of the data cell of downloading.
In step B2, check whether this locality has stored described fingerprint.
In step B3, while not storing described fingerprint in this locality, in the default public memory space in this locality, preserve the data cell of downloading.
In step B4, while having stored described fingerprint in this locality, delete the data cell of downloading.
Fingerprint in the present embodiment is to calculate by the content to data cell, can unique identification data content, the algorithm of calculated fingerprint is as Message Digest Algorithm 5 (Message Digest Algorithm, MD5), Secure Hash Algorithm (Secure Hash Algorithm, SHA) etc.
In the present embodiment, behind downloading data unit, calculate the fingerprint of this data cell, check whether this locality has had this fingerprint, if there has been this fingerprint, represent to have stored the data cell that this fingerprint is corresponding, the data cell of download can be deleted, and does not need repeated storage.If there is not this fingerprint, represent there is not the data cell that this fingerprint is corresponding, the data cell of download can be stored.Can reduce like this repeated storage, save memory space.And, the data cell of downloading from end (being common data) is stored in public memory space by the present embodiment, namely common data is concentrated to storage, while being convenient to receive broadcast, check whether this locality has the data that other terminal needs, and be convenient to the maintenance of common data.
For example, terminal 1 was once downloaded data cell 1 from website xxx1, data cell 1 be designated the first mark 1, corresponding fingerprint is 112aaa111.Terminal 1 obtains structured data from website xxx2 now, and parses the second mark 1.Because the second mark 1 is different from the first mark 1, so terminal 1 is determined the local data cell that does not have the second mark 1 correspondence, need to download.Then terminal 1 has been downloaded the data cell 1 of the second mark 1 correspondence from other end.112aaa111 after the fingerprint of the data cell 1 that acquisition is downloaded, terminal 1 is determined this locality storage data units 1, the data cell of download 1 is deleted, and as deleted from buffer memory, does not need in other words the data cell of download 1 to carry out permanent storage.
In one embodiment, in order to reduce repeated downloads data in the future, described method can also be set up the corresponding relation of described fingerprint and described the first mark.
In conjunction with example above, terminal 1 identifies behind 1 downloading data unit 1 by second, determines that by the fingerprint 112aaa111 of data cell 1 this locality has had data cell 1, and terminal 1 can also be set up the corresponding relation of fingerprint 112aaa111 and the second mark 1.When terminal 1 parses the second mark 1 again from structured data, do not need downloading data unit 1, because store this locality.Therefore network traffics have been saved.And in the time that other terminal broadcast second identifies 1, terminal 1 also can provide data for other terminal.Being equivalent to the Data Source that terminal 1 can be used as the first mark 1 and the second mark 1, is also the expansion to Data Source, contributes to improve download efficiency.
In one embodiment, in the time that the value of shared attribute field that has data cell is privately owned value, download the data cell of privately owned value correspondence from server.
For example, user 1 network data comprises individual photo of the user 1 and user 1 and other user's chat record.Individual photo is configured to common data by user 1, and the value of sharing attribute field is common value.Other user can download and check individual photo of the user 1.But user 1 does not wish that other user checks his chat record, therefore chat record is configured to private data, the value of sharing attribute field is privately owned value.
User 2 wishes the network data of download user 1 by terminal 1, and obtains user 1 mandate, can download chat record.Terminal 1 can be from the chat record of server download user 1, and the individual photo of other end download user 1 from WLAN (wireless local area network).
