Embodiment
Below with reference to accompanying drawings the disclosure is described.It should be noted that following being described in is only explanatory and exemplary in essence, never as any restriction to the disclosure and application or use.Unless stated otherwise, otherwise positioned opposite and numerical expression and the numerical value of the parts of setting forth in an embodiment and step do not limit the scope of the present disclosure.In addition, technology well known by persons skilled in the art, method and apparatus may not be discussed in detail, but are intended to the part becoming specification in appropriate circumstances.
In actual transmissions environment, once interrupt the data traffic V of needs re-transmission (namely, the size of a blocks of files) re-transmission time T change with the difference of transmission rate R, transmission rate R is higher, retransmit the time T needed shorter, such as, 1M data flow traffic may need 2 minutes in 2G transmission environment, but only may need for 1 second in 3G transmission environment, and only may need for 0.1 second in the transmission environment of 4G and WiFi.
The following embodiment of the disclosure is for different file sizes, and the transmission channel of different rates, the wireless transmission environments of different stability, adopt the parameters of user and the breakpoint transmission of server common setups to make efficiency of transmission reach the highest, Consumer's Experience is best.
Fig. 1 is the structural representation of disclosure breakpoint transmission system.
As shown in Figure 1, this system by the parameter setting module of client/browser side, reporting parameters module, blocks of files receiver module and memory, the blocks of files size setting module of server side, file division module, blocks of files sending module, file system composition.The blocks of files maxsize V that this system provides acceptable needs to retransmit for user
maxwith maximum retransmit time T
maxsetting, this parameters reports server by client/browser, and file is split according to corresponding blocks of files size when measuring and calculating efficiency of transmission is the highest according to the parameter reported and real-time Transmission speed by server.Further, in document transmission process, when transmission rate generation marked change, or because of wireless transmission environments, mobile state of terminal change cause interrupting frequently occurring time, server adjusts the size of blocks of files automatically, makes efficiency of transmission the highest.Disclosure embodiment, under the prerequisite meeting user's requirement, can reach best file transmission efficiency.
Fig. 2 is the schematic flow sheet of the method for the breakpoint transmission of a disclosure embodiment.
As shown in Figure 2, this embodiment can comprise the following steps:
S202, receives blocks of files maxsize and the maximum retransmit time of user's setting;
Wherein, user can select according to provided multiple options or arrange blocks of files maxsize and maximum retransmit time according to the demand of oneself.User file block size will cause the different of final delivery flow rate from the different of transmission time.When blocks of files occurring and retransmitting, if expect to produce less delivery flow rate, then less blocks of files maxsize can be set.
S204, determines the size of blocks of files according to current real-time Transmission speed and the blocks of files maxsize received and maximum retransmit time.
In this embodiment, the blocks of files maxsize set by user, maximum retransmit time and real-time Transmission speed has been considered in size process due to the transfer files block determining, larger blocks of files can be transmitted like this when real-time Transmission speed is higher, less blocks of files can be transmitted when real-time Transmission speed is lower, therefore can make the maximise transmission efficiency of file.
In an example, determine that the step of the size of blocks of files can comprise according to current real-time Transmission speed and the blocks of files maxsize received and maximum retransmit time:
The size of blocks of files is gone out according to current real-time Transmission speed and maximum retransmit Time Calculation;
The size of the blocks of files calculated and blocks of files maxsize are compared, if the size of the blocks of files calculated is greater than blocks of files maxsize, then using the size of blocks of files maxsize as determined blocks of files.That is, if current real-time Transmission speed is higher, then transmit with blocks of files maxsize, otherwise, jointly determine blocks of files size according to real-time Transmission speed and maximum retransmit time.
Next, described in detail the size how determining blocks of files by an instantiation.
Usually, user is to blocks of files maxsize V
maxwith maximum retransmit time T
maxhave requirement, the blocks of files maxsize V that user can accept
maxwith maximum retransmit time T
maxbe can be pre-determined, therefore, multiple options for user can be provided to select, such as, (1) 100k and 3 second; (2) 1M and 10 second; (3) 10M and 10 second; (4) 100M and 10 second.
The self-regulating process of routine supporting paper block in different transmission environment is chosen as below with above-mentioned.
(1) in 2G/3G/4G transmission environment, blocks of files maxsize V
maxwith maximum retransmit time T
maxbe respectively 100k and 3s, be expressed as by mathematical expression: [V<=100k, V<=3R], that is, as R<=33.33kbps, T=T
max=3s, V=T*R=3R; As R>33.33kbps, T=100k/R, V=V
max=100k.Under 2G transmission environment, blocks of files size is directly proportional to transmission rate, until reach blocks of files maxsize 100k; R under 3G and 4G transmission environment is substantially at more than 33.33kbps, so blocks of files size is 100k in most cases.
(2) in 2G/3G/4G transmission environment, blocks of files maxsize V
maxwith maximum retransmit time T
maxbe respectively 1M and 10 second, be expressed as by mathematical expression: [V<=1M, V<=10R], that is, as R<=100kbps, T=T
max=10s, V=T*R=10R; As R>100kbps, T=1M/R, V=V
max=1M.Under 2G transmission environment, blocks of files size is directly proportional to transmission rate, until reach blocks of files maxsize 1M; R under 3G and 4G transmission environment is substantially at more than 100kbps, so blocks of files size is 1M in most cases.
(3) in 2G/3G/4G transmission environment, blocks of files maxsize V
maxwith maximum retransmit time T
maxbe respectively 10M and 10 second, be expressed as by mathematical expression: [V<=10M, V<=10R], that is, as R<=1Mbps, T=T
max=10s, V=T*R=10R; As R>1Mbps, T=10M/R, V=V
max=10M.10M blocks of files needs several minutes ability end of transmissions under 2G transmission environment, can not meet the requirement of the maximum retransmit time of general user; Under 3G transmission environment, blocks of files size is directly proportional to transmission rate, until reach blocks of files maxsize 10M; Under 4G transmission environment, transmission rate is mostly at more than 1Mbps, so blocks of files size is 10M in most cases.
(4) in 2G/3G/4G transmission environment, blocks of files maxsize V
maxwith maximum retransmit time T
maxbe respectively 100M and 10 second, be expressed as by mathematical equation: [V<=100M, V<=10R], that is, as R<=10Mbps, T=T
max=10s, V=T*R=10R; As R>10Mbps, T=100M/R, V=V
max=100M.When setting 100M and 10 second, be not suitable for by the so large data of 2G/3G transmission; Under 4G transmission environment, blocks of files size is directly proportional to transmission rate, until reach blocks of files maxsize 100M.
(5) in WiFi transmission environment, access for free WiFi, user is more concerned about maximum retransmit time T
max, therefore, the size of blocks of files depends on the maximum retransmit time T that user sets
maxwith channel transmission rate R, the size of blocks of files equals T*R.For the WiFi access of charge, user's parameters of the size reference 2G/3G/4G of blocks of files.
In another example, in document transmission process, when the rate of change of real-time Transmission speed exceedes setting thresholding, the size of adjustment blocks of files automatically.
Such as, when the rate of change of real-time Transmission speed exceedes setting thresholding, and when real-time Transmission speed is slack-off, reduce the size of blocks of files.When the rate of change of real-time Transmission speed exceedes setting thresholding, and when real-time Transmission speed accelerates, increase the size of blocks of files, until blocks of files maxsize.
Wherein, the size of blocks of files can automatically be adjusted in a stepwise manner.Such as, the lower limit of blocks of files size to this interval of the upper limit of blocks of files size can be divided into multiple sections equably, every section is a stepping.When meeting the adjustment of blocks of files size, the adjusted value of each blocks of files size is a step value.
In an instantiation, transmission rate transmits standard (such as at it, change between minimum-rate 2G/3G/4G) and maximum rate, the renewal to blocks of files size is just triggered when the rate of change of transmission rate exceedes (maximum rate-minimum-rate)/4, can value in a stepping manner to the renewal of blocks of files size, wherein, stepping=(blocks of files maxsize-blocks of files size lower limit)/4.Blocks of files size is value between blocks of files maxsize and blocks of files size lower limit correspondingly, have 5 numerical value: blocks of files size lower limit, the lower limit+stepping of blocks of files size ,+two steppings of blocks of files size lower limit, + three steppings of blocks of files size lower limit, blocks of files maxsize.The section of fixing time is drawn (such as during transmission rate test, 200 milliseconds or other suitable value) mean value, filter out the transmission rate sudden change of moment, avoiding reducing efficiency of transmission because frequently adjusting blocks of files size, increasing the burden of client and server.Set less number of steps, as 4 maximum number of steps, to avoid the size adjusting blocks of files in transmitting procedure too continually.
In a further example, the size of blocks of files automatically can be adjusted according to the interruption number of retransmissions of identical file block.Illustrate, the number of retransmissions of identical file block is more, illustrates that the situation of transmission channel is poorer, and in order to improve efficiency of transmission, now the size of blocks of files just should be less.
Such as, when server retransmits same file block 2 times because Transmission is continuous, the size of the 3rd retransmission file block reduces a stepping automatically, during continuous 3 re-transmission same file blocks, the size of the 4th blocks of files reduces a stepping more automatically, during continuous 4 re-transmission same file blocks, the size of the 5th retransmission file block reduces a stepping more automatically.In addition, if continuous several times (such as, 4 times) retransmit same file block still failed time, user can be pointed out whether to suspend transfer files.
This interruption number of retransmissions according to identical file block adjusts the size of blocks of files automatically, make the transmission of blocks of files in different wireless communications environments, and terminal is in different mobile statuss, still can keeps best efficiency of transmission, reach adaptive object.
Further, after repeatedly retransmitting identical file block, if there is not Transmission in the process transmitting a setting number blocks of files continuously, then show that the situation of transmission channel takes a turn for the better to some extent, the size of blocks of files can be redefined, to improve efficiency of transmission according to current real-time Transmission speed and the blocks of files maxsize received and maximum retransmit time.
Such as, if such as, transmitting continuously in M blocks of files (wherein, M can according to service needed and transmission environment setting, and, M gets 100) process, do not interrupt, again can recalculate the size of blocks of files according to current transmission rate.
In a further example, in the process that Transmission does not occur, in the setting-up time after the size once adjusting blocks of files, no longer adjust the size of blocks of files.That is, the shortest time of enactment document block size adjustment.
Such as, when not there is Transmission, server is once adjusting the N second after blocks of files size (wherein, N can according to service needed and transmission environment setting, such as, N gets 3) in, even if the regularization condition meeting blocks of files size also no longer adjusts the size of blocks of files, to avoid the size adjusting blocks of files in normal transmission process too continually.
Parameter in above-mentioned example and number of times are supposed for convenience, and in example, the setting of various parameter, number of times can be experienced in conjunction with business need and actual user and adjust.
When startup file block adaptive transmits, client/browser is first by the reporting parameters server of user's selection, the parameter of server according to reception and the size of channel transmission rate determination blocks of files, files block sequence number and integrity check value can be attached (such as during the transmission of each blocks of files, Hash digital digest), during transmission first blocks of files, also can simultaneously accompanying document block size information.When server adjustment blocks of files size, when transmitting first blocks of files after adjustment, the blocks of files size information simultaneously after subsidiary upper adjustment, or blocks of files size variation step value.When occurring for some reason to interrupt, there is the blocks of files of interrupting in server re-transmissions, and subsidiary files block size information.
Client/browser is first according to the blocks of files size information log file block sequence number received, and check continuity, then preserves the blocks of files of reception.After client/browser receives all files block of whole file, integrate according to blocks of files sequence number and recover whole file.When occurring for some reason to interrupt, client/browser abandons the blocks of files occurring to interrupt, the blocks of files that reception server resends.
Above-mentioned example makes blocks of files size automatically can adapt to the transmission channel of different rates; Blocks of files size can adapt to the change of wireless transmission environments automatically; Blocks of files size can adapt to the different mobile statuss of terminal automatically; Can efficiency of transmission be improved, the flexibility of selection is provided to user, improve Consumer's Experience.
