For further setting forth the present invention, realize technological means and the effect that predetermined goal of the invention is taked, below in conjunction with accompanying drawing and preferred embodiment, to according to the specific embodiment of the present invention, structure, feature and effect thereof, be described in detail as follows.
The first embodiment
First embodiment of the invention provides a kind of document transmission method, and it can be carried out by a transmitting terminal, for file being sent to a receiving terminal.Above-mentioned transmitting terminal and receiving terminal are for example computer, mobile electronic terminal or other similar arithmetic units.Consult shown in Fig. 1, it is the above-mentioned document transmission method environment schematic diagram while carrying out.Transmitting terminal 110 is connected with receiving terminal 120 by network 10.This network 10 can be internetwork connection mode arbitrarily, such as the Internet (Internet), mobile Internet (2G, the 3G network that provide as telecom operators), local area network (LAN) (wired or wireless) etc.
Below in conjunction with specific embodiment, above-mentioned document transmission method is described in detail as follows:
The flow chart of the document transmission method that Fig. 2 provides for the first embodiment, this document transmission method comprises the following steps:
Step S101, extracts a burst the file to be transmitted to receiving terminal 120;
Step S102, is committed to queue to be transmitted by this burst, and monitors whether transmission success of this burst;
Step S103, if this burst transmission success not judges whether the number of retransmissions of this burst reaches default frequency threshold value;
Step S104 if the number of retransmissions of this burst does not reach this frequency threshold value, re-executes described step S102, and upgrades the number of retransmissions of this burst after waiting for one section of Preset Time.
According to above-mentioned document transmission method, after the single burst bust this of file, to wait for a period of time and retransmit again this burst, once just retransmit at once the mode of burst than traditional bust this, the method can improve the transmission success rate of the single burst of file, and then promotes the transmission success rate of this document.
In some instances, each step of said method to realize details as follows:
File described in step S101 can be picture, document, video etc.In the present embodiment, can from this document, extract burst according to fixing burst size.If transmit first this document, the starting point that the first byte of this document of take is first burst is extracted this first burst, when this first burst is successfully transferred to after this receiving terminal 120, then the starting point of next burst is set according to this fixing burst size, and the rest may be inferred.If again transmit this document after failure, the starting point that the first byte of this document of still take is first burst is extracted this first burst.When this first burst is successfully transferred to after this receiving terminal 120, receive the successfully byte number of this document of reception that this receiving terminal 120 returns, this byte number again receiving terminal 120 being returned is made as the starting point of next burst, to realize, be connected on that success has been transmitted burst is follow-up resumes defeated this document, i.e. " breakpoint transmission ".
In step S102, this transmitting terminal 110 and this receiving terminal 120 can be to connect based on transmission control protocol (Transmission Control Protocol, TCP).Accordingly, described queue to be transmitted can be the output buffer of TCP.A minute sector-meeting that is positioned at this output buffer transfers to operating system to complete the transmission of physical layer.Concrete physical layer process of transmitting is controlled by operating system, does not repeat them here.
In the present embodiment, can also first to this burst and this document, be encrypted, for example use MD5(Message-Digest Algorithm5, Message Digest Algorithm 5) cryptographic algorithm is processed, then the secret value of this burst and secret value and this document is packaged into a packet and is committed to this queue to be transmitted, to guarantee this burst and the file integrality in transmitting procedure.
Whether transmission success can adopt setting not receive the method for the time-out time of return information to monitor this burst.In the time-out time setting, if do not receive the return information that this receiving terminal 120 returns, judge this burst bust this.If receive the return information that this receiving terminal 120 returns in the time-out time setting, according to this return information, judge whether transmission success of this burst.
The number of times that number of retransmissions described in step S103 is transmitted for being again committed to this queue to be transmitted after the each bust this of this burst.When a burst is transmitted first, the number of retransmissions of this burst is initialized as to zero, while again transmitting afterwards, by the number of retransmissions of this burst of accumulative total after this burst bust this.If the number of retransmissions of this burst reaches this frequency threshold value, judge this document bust this, can finish transmission or again transmit this document.
Preset Time described in step S104 extends the increase of the number of retransmissions along with this burst.Extend this Preset Time and can adopt the method for exponential backspace, for example first arrange one fiducial time Ti, suppose that the number of retransmissions of this burst is C, and this Preset Time is T0, the computing formula of this T0 can be: T0=Ti*2^ (C-1).After the bust this first of this burst, wait for this fiducial time and retransmit again after Ti that if bust this again after retransmitting current waits for that the rest may be inferred than retransmitting this burst after the time of this fiducial time of many one times of Ti again again.Owing to returning to normal condition from malfunction under the poor the Internet of network quality, need to spend the more time, after the wait of Preset Time, retransmit this burst, the transmission success rate that can make this burst is higher compared to retransmitting at once this burst after bust this again.
The second embodiment
In order to realize the complete transmission of file, consult shown in Fig. 3, the second embodiment provides a kind of document transmission method, and it further comprises after described step S102 than the document transmission method of the first embodiment:
Step S105, if this burst transmission success checks whether this document is transmitted, if this document is not transmitted, returns to step S101, if this document is transmitted, judges this document transmission success.Particularly, consult shown in Fig. 4, the step whether described inspection this document has been transmitted comprises:
Step S105.1, receives the return information that this receiving terminal 120 returns, and this return information comprises that this receiving terminal 120 has received the summation of all burst sizes of this document.
Step S105.2, judges that this receiving terminal 120 has received the summation of all burst sizes of this document and whether the size of this document equates, if so, judges that this document is transmitted, if not, judges that this document is not transmitted.
Through above-mentioned flow process, can determine whether this document is transmitted, if this document is not transmitted, continues to extract next burst and transmit from this document, until file transfer completes.
The 3rd embodiment
The document transmission method providing according to the first embodiment is transfer files on the internet, is according to fixing burst size, to extract burst from this document to transmit successively.Yet under the network of different quality and bandwidth, when the size of file fragmentation only reaches some values, transmission rate just can reach the maximum under this network.Therefore,, while adopting the burst of fixed size to transmit, if network quality is fine, and the size of burst relatively hour, just may limit transmission rate.Especially in the network bandwidth and the frequent mobile Internet changing of quality, if the size of burst is improper, will make network can not bring into play maximum transmittability, cannot promote the transmission speed of file.
For further addressing the above problem, to consult shown in Fig. 5, third embodiment of the invention provides a kind of document transmission method, and it is than the document transmission method of the first embodiment, and described step S101 further comprises:
Step S201, obtains that in this document, at least one has completed the transformation parameter of the burst of transmission, and this transformation parameter comprises burst size and transmission rate;
Step S202, according to this, at least one has completed the transformation parameter computation rate variability index of the burst of transmission, and this rate variation index characterizes transmission rate with respect to the speed of this burst size variation;
Step S203, judges whether this rate variation index is less than default first threshold, and if so, upgrading current transmission state is a different state;
Step S204, obtain with deserve before coefficient corresponding to transmission state, and the size of setting current burst to be transmitted is in this document, to complete recently the burst size of transmission and the product of this coefficient;
Step S205 intercepts current burst waiting for transmission according to the size of this current burst to be transmitted setting and transmits from this document.
According to above-mentioned document transmission method, according to the transformation parameter size of the current burst to be transmitted of enactment document dynamically that has completed the burst of transmission in file, can make the size of burst to be transmitted before deserving can adapt to the requirement of network quality and bandwidth, thereby promote the effective bandwidth of network when transfer files and the transmission speed of file.
In some instances, each step of said method to realize details as follows:
Size and transmission time that transmission rate described in step S201 can complete the burst of transmission according to each calculate.This transmission time refers to that corresponding burst receives the expression that this receiving terminal 120 replys and receives the time period successful information from sending to.Calculate after this transmission rate, can also use predefined smoothing factor to carry out smoothing processing to this transmission rate.
Rate variation index described in step S202 characterizes transmission rate with respect to the speed of this burst size variation, and at this, at least one has completed in the burst of transmission, when burst size variation, and the corresponding situation of change of transmission rate of burst.When burst size increases with certain growth rate, this transmission rate also has corresponding lifting, illustrates that now the growth rate of burst size can meet the requirement that this transmission rate promotes.And when burst size increases with this growth rate, this transmission rate is corresponding lifting not, illustrate that now the growth rate of burst size can not meet the requirement that transmission rate promotes, need to slow down the growth rate of burst size or keep burst size constant.
Whether the first threshold described in step S203 can meet for defining the growth rate of burst size the requirement that transmission rate promotes.Described current transmission state represents the growth rate of this burst size.In the present embodiment, deserve front transmission state and comprise the first state, the second state and the third state.Each state corresponding one for representing the coefficient of the growth rate of burst size.Wherein, this first state and coefficient corresponding to the second state are greater than 1, and coefficient corresponding to the first state be greater than the coefficient that the second state is corresponding, represent that the growth rate of burst size under the first state will be higher than the growth rate of burst size under the second state.Coefficient corresponding to this third state is 1, represents that under the third state, burst size remains unchanged.
Particularly, step S203 also comprises and determines current transmission state, if this rate variation index is less than this first threshold, and current transmission state is this first state, and upgrading current transmission state is this second state, slows down the growth rate of this burst size.If this rate variation index is less than this first threshold, and current transmission state is this second state, upgrades current transmission state for this third state, further slows down the growth rate of this burst size.
Step S204 obtain with upgrade after deserve before coefficient corresponding to transmission state, and the size of setting current burst to be transmitted completes the burst size of transmission and the product of this coefficient recently for this.If transmission state be the first state or the second state before deserving, at this, complete recently on the basis of burst size of transmission corresponding increase to set the size of burst to be transmitted.If transmission state is the third state before deserving, the size of setting burst to be transmitted is identical with the burst size that this completes transmission recently.
Step S205 intercepts current burst waiting for transmission according to the size of this current burst to be transmitted setting from this document, then carries out described step S102 to transmit this burst.
The 4th embodiment
Consult shown in Fig. 6, fourth embodiment of the invention provides a kind of document transmission method, document transmission method than the 3rd embodiment, update condition to transmission state before deserving has been made further restriction, so that the size of the burst to be transmitted setting adapts to the transmittability of network more, thus the transmission speed of lifting file.
Than the document transmission method of the 3rd embodiment, the document transmission method of the present embodiment further comprises:
Step S200, before carrying out described step S201, judge whether current burst waiting for transmission is the first burst of this document, if the first burst that current burst waiting for transmission is this document, perform step S206, if current burst waiting for transmission is not the first burst of this document, carry out described step S201.
Step S206, the size of setting current burst to be transmitted is the default value of burst size under current network type (the 2G/3G network providing such as telecom operators, WIFI network etc.), and should be updated to this first state by front transmission state, then perform step S205.
Step S207, before carrying out described step S203, determines and deserves whether front transmission state is this first state or the second state.If current state is the first state or the second state, perform step S208.If current state is the third state, perform step S209.
Step S208, at least one has completed in the burst of transmission to judge this, and whether the access times of every kind of burst size reach respectively default Second Threshold (for example 2 times).If the access times of this every kind burst size reach this Second Threshold, carry out described step S203, if the access times of this every kind burst size do not reach this Second Threshold, carry out described step S204.
Step S209, add up this at least one completed the burst of transmission transmission rate exceed continuously the number of times of preset range, and whether the number of times that judgement is added up reaches the 3rd default threshold value.If the number of times of adding up does not reach the 3rd threshold value, carry out described step S204.If the number of times of adding up reaches the 3rd threshold value, carry out described step S206.
It should be noted that, because the size of file part to be sent may be not enough to intercept current burst waiting for transmission according to the size of the current burst to be transmitted setting from this document, or the size at the current burst to be transmitted according to setting intercepts after current burst waiting for transmission from this document, the size of file part to be sent is less, need not again file part to be sent be transmitted as next burst, therefore, described step S204 and step S206 may further include: whether the size that judges this document part to be sent is less than the 4th default threshold value.If the size of this document part to be sent is less than the 4th threshold value, the size of setting current burst to be transmitted is the size of this document part to be sent, and then carries out described step S205.If the size of this document part to be sent is not less than the 4th threshold value, directly carry out this step S205.
According to the document transmission method of this enforcement, the update condition of transmission state before deserving has been made to further restriction, can make the size of the burst to be transmitted that sets more adapt to the transmittability of network, thereby promote the transmission speed of file.

The 6th embodiment
The document transmission method providing according to the first embodiment is transfer files on the internet, is adopt to set the time-out time of not receiving return information to monitor whether transmission success of burst.This time-out time is generally fixed value or the dynamic value estimating according to the average bandwidth of burst size and different the Internets or nearest historical bandwidth measured data.
Yet, because mobile Internet is that non-WIFI network of network mass change is very fast and amplitude is very large especially, the cable network that is far from is so stable, and in the time of the overwhelming majority, the actual bandwidth under a certain mobile Internet all has very large gap with the average bandwidth that statistics obtains.Therefore use the time-out time estimating according to the average bandwidth of burst size and the Internet, in the actual transmissions process of file fragmentation, will be very easy to overtime.And be " discontinuous ", " saltus step " soon and often because the network quality of mobile Internet changes, the bandwidth of the eve measuring according to history is difficult to go to estimate as a foundation bandwidth at rear a moment.Therefore, with setting this time-out time, monitor whether transmission success of burst, easily cause the transmission failure rate of the single burst of file very high.In addition, owing to reaching time-out time, declare after the burst bust this of file, data still can be through the complete transmitting procedure that just can finish this burst of Internet Transmission, causes the flow that the whole process of transmitting of this burst produces all because of the result of bust this, to slattern.
For further addressing the above problem, to consult shown in Fig. 8, sixth embodiment of the invention provides a kind of document transmission method, and it is than the document transmission method of the first embodiment, and described step S102 further comprises:
Step S301 is committed to the burst extracting from this document in this queue to be transmitted in a host process;
Step S302, continues to wait for interrupt signal;
Step S303, whether within a predetermined period of time have upstream volume production raw, if not, send interrupt latency request, and add the information that this host process does not produce upstream data flow within a predetermined period of time in this interrupt latency request if monitoring this host process;
Step S304, if receive the return information that this interrupt latency request or this receiving terminal return, finishes this step S302.
According to the document transmission method of the present embodiment, the duration that adopts monitoring host process not produce upstream data flow judges whether transmission success of burst, than the overtime processing mode of traditional transmission, can adapt to better unsettled network environment as mobile Internet, improve the success rate of burst transmission, and reduce the flow waste causing due to timeout issue in burst transmitting procedure.
In some instances, each step of said method to realize details as follows:
Host process described in step S301 refers to the process that will transmit this burst.For example, the process at a certain file transfer applications place.This burst can be packaged into network packet according to HTML (Hypertext Markup Language) (HyperText Transfer Protocol, HTTP).
Interrupt signal described in step S302 comprises return information that described interrupt latency request or receiving terminal 120 return etc.In addition,, in the process of carrying out at step S302, can also interrupt the execution of host process.
Step S303 can carry out in being different from a new monitoring process of this host process.Described predetermined amount of time is the network timeout period that can allow, and it can be set according to concrete needs, for example, can select 5 seconds.Described upstream data flow is that host process is submitted to this burst after this queue to be transmitted, and this queue to be transmitted transfers to operating system to be gone out and produced by Internet Transmission this burst.
If host process does not produce upstream data flow in this predetermined amount of time, illustrate that host process is passed Internet Transmission without any a byte and goes out in this predetermined amount of time, mean this this burst bust this, therefore need to send this interrupt latency request so that host process stops waiting for interrupt signal.After sending this interrupt latency request, this step S303 finishes.
If host process has upstream volume production raw in this predetermined amount of time, illustrate that host process has data to be passed Internet Transmission and goes out in this predetermined amount of time, mean that this burst is just in process of transmitting.The anxiety producing due to wait for fear of user, if host process has upstream volume production raw in this predetermined amount of time, step S303 can also point out user's this document to send by modes such as animation, words.
In step S304, if owing to receiving this interrupt latency request end step S302, according to this host process additional in this interrupt latency request, do not produce within a predetermined period of time the information of upstream data flow, return to the transmission result of this burst bust this.If owing to receiving the return information that receiving terminal 120 returns and end step S302 judges according to this return information whether this receiving terminal 120 successfully receives this burst.If this burst of the unsuccessful reception of this receiving terminal 120, also returns to the transmission result of this burst bust this.If this receiving terminal 120 successfully receives this burst, return to the transmission result of this burst transmission success.After receiving the return information that this receiving terminal 120 returns, trigger step S303 and finish.
In addition, after step S302, can also there is a monitoring whether Network Abnormal occurs, such as network, connect the step of Network Abnormals such as disconnecting, network connection is restricted.If there is this Network Abnormal, end step S302 and step S303, and return to the transmission result of this burst bust this.
