Abstract
The invention discloses a data transmission method which comprises the following steps: a data transmitting unit carries out sampling identification on a key characteristic of data to be sent to form characteristic information of the data to be sent; the data transmitting unit transmits the characteristic information of the data to be sent to a data receiving unit; the data receiving unit receives the characteristic information of the data to be sent and retrieves data with same characteristic information at local, and if the data is retrieved, the data receiving unit sends a list of the data with the same characteristic information at local to the data transmitting unit; the data transmitting unit receives the list and abandons the data to be sent in the list, and the data receiving unit acquires the data same with the data to be sent in the list at local. By employing a technical scheme of the invention, through a method of intelligent determination of repeated data, a network data flow is reduced, and an effect of a network transmission speed is greatly improved.
Description
Technical field
The present invention relates to the network transmission technology field, relate in particular to a kind of method that transmits data.
Background technology
Along with the arrival of information age, the information interchange between the people is more and more frequent, and content is also more and more, the especially appearance of computer network, and more people's information interchange provides instrument easily.But owing to just be the rising of exponential curve through the data of computer network transmission, the transfer of data pressure of computer network is also increasing.Existing file data transmission is served, and when the transmission data, can't carry out the Intelligent Measurement of repeating data to the data that are transmitted.For example; The user in the GMAIL mailing system, with the file of same 1M as annex give this user a plurality of friends everyone when sending an envelope mail, need all upload this attachment files once for every envelope mail; Each flow that all need consume 1M, not only time-consuming but also take flow.
Summary of the invention
The objective of the invention is to propose a kind of method of transmitting data, can reduce network traffic data, improve network transfer speeds greatly.
For reaching this purpose, the present invention adopts following technical scheme:
A kind of method that transmits data may further comprise the steps:
A, data transmission unit identify the key feature sampling of data to be sent, form the characteristic information of data to be sent;
B, data transmission unit send to the Data Receiving unit with the characteristic information of data to be sent;
After C, Data Receiving unit received the characteristic information of data to be sent, retrieval had the data of same characteristic features information in this locality, if retrieval has, the Data Receiving unit sends to data transmission unit with the tabulation that said this locality has the data of same characteristic features information;
D, data transmission unit receive tabulation, abandon sending the data to be sent in the tabulation, the Data Receiving unit this locality obtain with tabulate in the identical data of data to be sent.
In the steps A, further comprising the steps of:
Data transmission unit is divided into data to be sent and is no less than 2 data cell, with each data cell as data to be sent.
Further comprising the steps of:
If the Data Receiving unit does not retrieve the data with same characteristic features information in this locality; Data transmission unit sends to the Data Receiving unit with data and the characteristic information thereof that said Data Receiving unit does not retrieve in this locality, and the Data Receiving unit obtains data and characteristic information thereof.
The characteristic information of data to be sent comprises MD5 functional value, document creation time and the file name of file size, file.
Adopted technical scheme of the present invention, can reach the minimizing network traffic data, improved the effect of network transfer speeds greatly through the method for intelligent decision repeating data.
Description of drawings
Fig. 1 is the flow chart that transmits data in the specific embodiment of the invention.
Embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and through embodiment.
Fig. 1 is the flow chart that transmits data in the specific embodiment of the invention.As shown in Figure 1, the flow process of these transmission data may further comprise the steps:
For example need send two pictures, can be with each picture as a data unit.
Data transmission unit identifies the key feature sampling of each picture:
The characteristic information of first picture is: " file 1_ length: 1024254bytes; file 1_md5:d41d8cd98f00b204e9800998ecf8427e; file 1_ creation-time: 1999-10-10 12:12:34 122, file 1 name: christmas_gift.jpg ... ".
The characteristic information of second picture is: " file 2_ length: 66444bytes; file 2_md5:2efdabbaa580b0552d78dda96e7bc27e; file 2_ creation-time: 2010-10-10 12:12:34 122, file 2 names: dady_birthday.jpg ... ".
After step 103, Data Receiving unit received the characteristic information of data to be sent, retrieval had the data of same characteristic features information in this locality, if retrieval has, goes to step 104, if do not retrieve, then goes to step 106.
For example the Data Receiving unit find the characteristic information of a file also to be in this locality " file 2_ length: 66444bytes; file 2_md5:2efdabbaa580b0552d78dda96e7bc27e; file 2_ creation-time: 2010-10-10 12:12:34 122; file 2 names: dady_birthday.jpg ... } ", will second picture be put into tabulation and issue data transmission unit.After data transmission unit was received tabulation, with the data of not sending second picture, the Data Receiving unit directly obtained the data of second picture from this locality.
The above; Be merely the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, anyly is familiar with this technological people in the technical scope that the present invention disclosed; The variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
