Embodiment
Further to illustrate that the present invention is to realize technological means and effect that predetermined goal of the invention is taken, below in conjunction with Accompanying drawing and preferred embodiment, to embodiment, structure, feature and its effect according to the present invention, are described in detail as after.
First embodiment
First embodiment of the invention provides a kind of document transmission method, and it can be performed by a transmitting terminal, for file to be sent out Deliver in a receiving terminal.Above-mentioned transmitting terminal and receiving terminal are, for example, computer, mobile electronic terminal or other are similar Arithmetic unit.As shown in fig.1, environment schematic when it is performed for above-mentioned document transmission method.Transmitting terminal 110 passes through net Network 10 is connected with receiving terminal 120.The network 10 can be arbitrary internetwork connection mode, such as internet（Internet）, it is mobile Internet（2G, the 3G network provided such as telecom operators）, LAN（It is wired or wireless）Deng.
Above-mentioned document transmission method is described in detail as follows below in conjunction with specific embodiment：
The flow chart for the document transmission method that Fig. 2 provides for first embodiment, this document transmission method comprises the following steps：
Step S101, extracts a burst from the file to be passed for transporting to receiving terminal 120；
Step S102, queue to be transmitted is committed to by the burst, and monitor the burst whether transmission success；
Step S103, if the non-transmission success of the burst, judges whether the number of retransmissions of the burst reaches default number of times Threshold value；
Step S104, if the number of retransmissions of the burst is not up to the frequency threshold value, the weight after one section of preset time is waited The step S102 is newly performed, and updates the number of retransmissions of the burst.
According to above-mentioned document transmission method, after the single sliced transmission failure of file, it will wait for a period of time and weigh again The burst is passed, compared to traditional mode for retransmitting burst at once once bust this, this method can improve the list of file The transmission success rate of individual burst, and then lift the transmission success rate of this document.
In some instances, each step of the above method realizes that details is as follows：
File described in step S101 can be picture, document, video etc..In the present embodiment, can be according to fixed Burst size extracts burst from this document.If transmitting this document first, then using the first byte of this document as first burst Starting point extracts the first burst, after the first burst is successfully transferred to receiving terminal 120, further according to the burst size of the fixation The starting point of next burst is set, and the rest may be inferred.If failure after transmit this document again, then still using the first byte of this document as The starting point of first burst extracts the first burst.After the first burst is successfully transferred to receiving terminal 120, the receiving terminal is received The byte number of 120 this documents being properly received returned, then the byte number that receiving terminal 120 is returned is set to next burst " breakpoint transmission " starting point, resume defeated this document, i.e., to realize that the burst for being connected on Successful transmissions is follow-up.
In step S102, the transmitting terminal 110 and the receiving terminal 120 can be based on transmission control protocol （Transmission Control Protocol, TCP）Connection.Accordingly, described queue to be transmitted can be TCP Output buffer.Burst in the output buffer can transfer to the transmission of operating system completion physical layer.Specific physics Layer transmission process is controlled by operating system, will not be repeated here.
In the present embodiment, first the burst and this document can also be encrypted, such as using MD5 （Message-Digest Algorithm5, Message Digest Algorithm 5）AES processing, then by the burst and its add The secret value of close value and this document is packaged into a packet and is committed to the queue to be transmitted, to ensure the burst and file in biography Integrality during defeated.
Monitoring the burst, whether transmission success can use the method for setting the time-out time that do not receive return information.Institute In the time-out time of setting, if not receiving the return information of the receiving terminal 120 return, judge that the sliced transmission fails.If The return information of the receiving terminal 120 return is received in set time-out time, then judges that the burst is according to the return information No transmission success.
Number of retransmissions described in step S103 is to be committed to the queue to be transmitted again after each bust this of the burst The number of times being transmitted.When a burst is transmitted first, the number of retransmissions of the burst is initialized as zero, afterwards whenever this When being transmitted again after sliced transmission failure, the number of retransmissions of the burst will be added up.If the number of retransmissions of the burst reaches this Frequency threshold value, then judge this document bust this, can terminate to transmit or transmit again this document.
Preset time described in step S104 will extend with the increase of the number of retransmissions of the burst.Extend this it is default when Between can using index retract method, for example first set a fiducial time Ti, it is assumed that the number of retransmissions of the burst be C, and The preset time is T0, then the calculation formula of the T0 can be：T0=Ti*2^(C-1).After burst bust this first etc. Retransmitted again after after fiducial time Ti, if bust this again after current re-transmission, then one times would be waited more than fiducial time Ti Time after retransmit the burst again, the rest may be inferred.Due to being returned to just from malfunction under the poor internet of network quality Normal state needs to spend the more time, retransmits the burst again after the wait of preset time, can make the transmission of the burst Success rate is higher compared to the burst is retransmitted after bust this at once.
Second embodiment
In order to realize the complete transmission of file, as shown in fig.3, second embodiment provides a kind of document transmission method, its Compared to the document transmission method of first embodiment, further comprise after the step S102：
Step S105, if sliced transmission success, checks whether this document has been transmitted, if this document is not transferred Into then return to step S101, if this document has been transmitted, judges this document transmission success.Specifically, refering to Fig. 4 institutes Show, the step of whether described inspection this document has been transmitted includes：
Step S105.1, receives the return information of the receiving terminal 120 return, and the return information has included the receiving terminal 120 Receive the summation of all burst sizes of this document.
Step S105.2, judge the receiving terminal 120 received all burst sizes of this document summation and this document it is big It is small whether equal, if so, then judging that this document has been transmitted, if it is not, then judging that this document is not transmitted.
By above-mentioned flow, it may be determined that whether this document is transmitted, if this document is not transmitted, continue from this Extract next burst in file to be transmitted, until file is transmitted.
3rd embodiment
The document transmission method provided according to first embodiment transmits file on the internet, is big according to fixed burst The small burst that extracted from this document is transmitted successively.But under different quality and the network of bandwidth, the size of file fragmentation When only reaching some value, transmission rate can be only achieved the maximum under the network.Therefore, entered using the burst of fixed size Row transmission when, if network quality very well, and the size of burst it is relatively small when, it is possible to transmission rate can be limited.Especially In the mobile Internet that the network bandwidth and quality often change, if the size of burst is improper, network will be prevented from sending out Wave the transmittability of maximum, it is impossible to lift the transmission speed of file.
Further to solve the above problems, as shown in fig.5, third embodiment of the invention provides a kind of file transmission side Method, it is compared to the document transmission method of first embodiment, and described step S101 further comprises：
Step S201, obtains the configured transmission that at least one in this document has completed the burst of transmission, the configured transmission Including burst size and transmission rate；
Step S202, configured transmission computation rate variability index of at least one burst for having completed transmission according to this, The speed variability index characterizes speed of the transmission rate relative to the burst size variation；
Step S203, judges whether the speed variability index is less than default first threshold, if so, then updating current transmission State is a different state；
Step S204, obtains corresponding with present transmission state coefficient, and set the size of currently burst to be transmitted as The burst size of transmission and the product of the coefficient are recently completed in this document；
Step S205, is intercepted current waiting for transmission according to the size of the set current burst to be transmitted from this document Burst is transmitted.
According to above-mentioned document transmission method, dynamically set according to the configured transmission for the burst that transmission has been completed in file The size of the current burst to be transmitted of file, can make burst to be transmitted before deserving be sized to adapt to network quality and bandwidth It is required that, so as to lift the transmission speed of effective bandwidth and file of the network when transmitting file.
In some instances, each step of the above method realizes that details is as follows：
Transmission rate described in step S201 can be according to the size and transmission time of the burst for each having completed transmission Calculate.The transmission time refers to that the expression that the receiving terminal 120 is replied from sending to receiving of corresponding burst is received into Period between the information of work(.Calculate after the transmission rate, the transmission rate can also be used set in advance smooth The factor is smoothed.
Speed variability index described in step S202 characterizes transmission rate relative to the speed of the burst size variation, that is, exists This at least one completed in the burst of transmission, when burst size variation, the corresponding situation of change of transmission rate of burst. When burst size is increased with certain growth rate, the transmission rate also has corresponding lifting, then illustrates now burst size Growth rate can meet the transmission rate lifting requirement.And when burst size is increased with the growth rate, transmission speed Rate is not lifted accordingly, then illustrates the growth rate of now burst size and can not meet the requirement of transmission rate lifting, need Slow down the growth rate of burst size or keep burst size constant.
Whether the growth rate that the first threshold described in step S203 is used to define burst size disclosure satisfy that transmission rate The requirement of lifting.Described present transmission state is the growth rate for representing the burst size.In the present embodiment, forward pass is deserved Defeated state includes first state, the second state and the third state.Each state correspondence one is used for the growth for representing burst size The coefficient of speed.Wherein, the first state and the corresponding coefficient of the second state are more than 1, and the corresponding coefficient of first state is big In the corresponding coefficient of the second state, represent that the growth rate of burst size under first state is higher than burst size under the second state Growth rate.The corresponding coefficient of the third state is 1, represents that burst size keeps constant under the third state.
Specifically, step S203 also includes determining when preceding transmission state, if the speed variability index is less than first threshold Value, and present transmission state is the first state, then it is second state to update present transmission state, that is, slows down the burst size Growth rate.If the speed variability index is less than the first threshold, and present transmission state is second state, then updates and work as Preceding transmission state is the third state, i.e., further slow down the growth rate of the burst size.
Step S204 obtains coefficient corresponding with the present transmission state after renewal, and sets current burst to be transmitted Size is recently completed product of the burst size with the coefficient of transmission for this.If the present transmission state is first state or second State is then corresponding on the basis of this is recently completed the burst size of transmission to increase to set the size of burst to be transmitted.If should Present transmission state is the third state, then the size for setting burst to be transmitted is identical with the burst size that this is recently completed transmission.
Step S205 intercepts current waiting for transmission according to the size of the set current burst to be transmitted from this document Burst, then perform the step S102 to transmit the burst.
Fourth embodiment
As shown in fig.6, fourth embodiment of the invention provides a kind of document transmission method, compared to the text of 3rd embodiment Part transmission method, the update condition to the present transmission state has made further restriction, so that set burst to be transmitted Size more adapt to the transmittability of network, so as to lift the transmission speed of file.
Compared to the document transmission method of 3rd embodiment, the document transmission method of the present embodiment further comprises：
Step S200, before the step S201 is performed, judges whether current burst waiting for transmission is the first of this document Burst, if current burst waiting for transmission is the first burst of this document, performs step S206, if current burst waiting for transmission is not For the first burst of this document, then the step S201 is performed.
Step S206, sets the size of current burst to be transmitted as current network type（For example telecom operators provide 2G/3G networks, WIFI network etc.）The default value of lower burst size, and the present transmission state is updated to the first state, so Step S205 is performed afterwards.
Step S207, before the step S203 is performed, determine the present transmission state whether be the first state or Second state.If current state is first state or the second state, step S208 is performed.If current state is the third state, Then perform step S209.
Step S208, judging this, at least one has been completed in the burst of transmission, and the access times of every kind of burst size are It is no to respectively reach default Second Threshold（Such as 2 times）.If the access times of every kind of burst size reach the Second Threshold, The step S203 is performed, if the access times of every kind of burst size are not up to the Second Threshold, the step is performed S204。
Step S209, the transmission rate for counting at least one burst for having completed transmission continuously exceeds preset range Number of times, and judge whether counted number of times reaches default 3rd threshold value.If the number of times counted is not up to the 3rd threshold value, Then perform the step S204.If the number of times counted reaches the 3rd threshold value, the step S206 is performed.
Significantly, since the size of file part to be sent may be not enough to according to set current to be transmitted The size of burst intercepts current burst waiting for transmission from this document, or according to the big of set current burst to be transmitted Small to be intercepted from this document after current burst waiting for transmission, the size of file part to be sent is smaller, again need not treat file Transmitting portion is transmitted as next burst, therefore, and the step S204 and step S206 may further include：Judge Whether the size of this document part to be sent is less than default 4th threshold value.If the size of this document part to be sent be less than this Four threshold values, then set the size of current burst to be transmitted as the size of this document part to be sent, the step then performed again S205.If the size of this document part to be sent is not less than the 4th threshold value, step S205 is directly performed.
According to the document transmission method of this implementation, the update condition to the present transmission state has made further restriction, The size of set burst to be transmitted can be made more to adapt to the transmittability of network, so as to lift the transmission speed of file.
5th embodiment
As shown in fig.7, fifth embodiment of the invention provides a kind of document transmission method, it is compared to fourth embodiment Document transmission method, further proposes a kind of concrete implementation scheme to the step S101.First set in acquired this document At least one configured transmission for having completed the burst of transmission includes：The size S of the first burst of this document1, it is big in the burst Small S1Under transmission rate smooth value V1, it is recently completed the burst size S of transmissionn, in burst size SnUnder transmission rate Smooth value Vs, with burst size SnIt is different and in burst size SnThe burst size S transmitted recently before0, in the burst Size S0Under transmission rate smooth value V0.If the size of the current burst to be transmitted is Sn+1, then the present embodiment is compared to The document transmission method of four embodiments, the step S101 further comprises：
Step S11, judges the SnWhether it is 0.If SnIt is not 0, then it is not the head of this document to illustrate current burst waiting for transmission Individual burst, into step S12.If SnFor 0, then illustrate the first burst that current burst waiting for transmission is this document, into step S25。
Step S12, updates the SnAccess times N.
Step S13, according to the acquired S1、V1、Sn、Vs、S0And V0Calculate speed variability index S.Calculate the public affairs of the S Formula is：S=[(Vs-V0)/V1]/[(Sn-S0)/S1]。

Step S20, sets Sn+1For the corresponding coefficient B of the second state and SnProduct, subsequently into step S27.
Step S21, judges VsWith the reference speed rate V under the third statestableBetween difference whether be less than the default 3rd Threshold value.If it is not, illustrating that this is recently completed the transmission rate of the burst of transmission beyond the preset range, then into step S22.If It is to illustrate that this is recently completed the transmission rate of the burst of transmission without departing from the preset range, then into step S23.3rd threshold Value can be reference speed rate VstableWith certain percentage constant D product.
Step S22, the transmission rate for updating the burst for being recently completed transmission exceeds the number of times M of the preset range, that is, exists Jia 1 on the basis of the M.
Step S23, the number of times M by the transmission rate of the burst for being recently completed transmission beyond the preset range is reset.
Step S24, judges that this is recently completed whether the transmission rate of the burst of transmission reaches beyond the number of times M of the preset range To default 4th threshold value Mmax.If so, then entering step S25.If it is not, then entering step S26.

Sixth embodiment
The document transmission method provided according to first embodiment transmits file on the internet, is not received back using setting The time-out time of complex information come monitor burst whether transmission success.The time-out time be usually according to burst size with it is difference mutual A fixed value or dynamic value that the average bandwidth of networking or nearest history bandwidth measured data are estimated.
However, due to mobile Internet be especially non-WIFI network network quality change is very fast and amplitude very greatly, far Stablize not as cable network, in the overwhelming majority, a certain mobile interchange actual bandwidth off the net is all obtained with statistics Average bandwidth have very big gap.When therefore using the time-out estimated according to the average bandwidth of burst size and internet Between, by very easy time-out during the actual transmissions of file fragmentation.And because the network quality change of mobile Internet is fast And often " discontinuous ", " saltus step ", the bandwidth of the eve obtained according to history measurement is difficult to be gone as a foundation The bandwidth at a moment after estimation.Therefore, using set the time-out time come monitor burst whether transmission success, be easily caused file list The transmission failure rate of individual burst is very high.Further, since after reaching time-out time and declaring that the sliced transmission of file fails, data are also It is that can be finished through network transmission and can just terminate the transmitting procedure of the burst, produced by causing the whole transmission process of this burst Flow is all slatterned because of the result of bust this.
Further to solve the above problems, as shown in fig.8, sixth embodiment of the invention provides a kind of file transmission side Method, it is compared to the document transmission method of first embodiment, and described step S102 further comprises：
The burst extracted from this document, is committed in the queue to be transmitted by step S301 in a host process；
Step S302, persistently waits interrupt signal；
Step S303, monitors whether the host process has the generation of upstream amount within a predetermined period of time, if it is not, then sending Interrupt latency is asked, and the additional host process does not produce upstream data flow within a predetermined period of time in interrupt latency request Information；
Step S304, if receiving the return information that interrupt latency request or the receiving terminal are returned, terminates the step Rapid S302.
According to the document transmission method of the present embodiment, the duration of upstream data flow is not produced using monitoring host process Come judge burst whether transmission success, compared to the processing mode of traditional transmission time-out, can better adapt to unstable Network environment such as mobile Internet, improves the success rate of sliced transmission, and reduce during sliced transmission due to timeout issue Caused flow is wasted.
In some instances, each step of the above method realizes that details is as follows：
Host process described in step S301 refers to transmit the process of the burst.For example, a certain file transfer applications institute Process.The burst can be according to HTTP（HyperText Transfer Protocol, HTTP）It is packaged into Network packet.
Interrupt signal described in step S302 includes the reply letter that described interrupt latency request or receiving terminal 120 are returned Breath etc..In addition, during step S302 is performed, the execution of host process can also be interrupted.
Step S303 can be performed in different from the new monitoring process of the host process.Described predetermined amount of time It it is the network timeout period that can allow, it be able to can for example be selected 5 seconds according to being set the need for specific.Described is upper Row data traffic is that host process submits to the burst after the queue to be transmitted, and the burst is transferred to operation system by the queue to be transmitted System is gone out and produced by network transmission.
If host process does not produce upstream data flow in the predetermined amount of time, illustrate host process in the predetermined amount of time Interior none of byte is gone out by network transmission, it is meant that this sliced transmission fails, it is therefore desirable to send this Interrupt latency request is so that host process stops waiting interrupt signal.After interrupt latency request is sent, step S303 terminates.
If host process has the generation of upstream amount in the predetermined amount of time, illustrate host process in the predetermined amount of time Inside there are data to be gone out by network transmission, it is meant that the burst is just in transmission process.In order to avoid user is due to wait The anxiety of generation, if host process has the generation of upstream amount in the predetermined amount of time, step S303 can also pass through The modes such as animation, word point out user's this document to send.
In step S304, if being due to receive the interrupt latency request and end step S302, according to the interruption etc. Wait that the host process added in asking does not produce the information of upstream data flow within a predetermined period of time, return to sliced transmission mistake The transmission result lost.If be due to receive receiving terminal 120 return return information and end step S302, according to the reply Information judges whether the receiving terminal 120 is properly received the burst.If the receiving terminal 120 is not successfully received the burst, this is also returned to The transmission result of sliced transmission failure.If the receiving terminal 120 has been properly received the burst, returns to the sliced transmission and successfully pass Defeated result.After the return information of the receiving terminal 120 return is received, triggering step S303 terminates.
In addition, after step S302, can also there is one to monitor whether occur Network Abnormal, such as network connection disconnection, The step of network connection such as is restricted at the Network Abnormal.If occurring the Network Abnormal, end step S302 and step S303, and return Return the transmission result of sliced transmission failure.
7th embodiment
As shown in fig.9, seventh embodiment of the invention provides a kind of document transmission method, it is compared to sixth embodiment Document transmission method, further proposes a kind of implementation to the step S303：By periodically monitoring the host process Upstream data flow come judge host process whether have within a predetermined period of time upstream amount generation.Specifically, the step S303 includes：
