Detailed Description
Referring to the drawings, wherein like reference numbers refer to like elements, the principles of the present application are illustrated as being implemented in a suitable computing environment, and the embodiments described below are only some, but not all, embodiments of the present application. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
Please refer to fig. 1, which is a flow chart illustrating a data transmission method according to an embodiment of the present application, including:
step 101, acquiring bandwidth requirements of data to be transmitted during actual transmission, and selecting at least two target links according to the bandwidth requirements and the bandwidths of all existing links;
in the embodiment of the present invention, the data transmission method is implemented by a data transmission device, and the data transmission device belongs to an electronic device, and may be, for example, a chip, a server, a mobile phone terminal, a tablet computer, and the like. The data transmission device is stored in a readable storage medium of the electronic equipment, and when the data transmission device needs to be used, a processor of the electronic equipment can read and operate the data transmission device.
The data transmission method is suitable for performing cross-device data transmission between two electronic devices, one of the two electronic devices is a sending end, the other electronic device is a receiving end, and a plurality of links are stored between the sending end and the receiving end.
The data transmission method in the application is described from a sending end, and when the sending end has data to be transmitted and needs to send the data to a receiving end, the sending end acquires bandwidth requirements of the data to be transmitted during actual transmission, wherein the bandwidth requirements can be preset in the sending end, or can also be calculated based on a preset bandwidth calculation algorithm, and can be set based on requirements in actual application, and the limitation is not required at this time.
After the sending end obtains the bandwidth requirement, at least two target links are selected according to the bandwidth requirement and the bandwidth of each existing link, wherein a plurality of links are arranged between the sending end and the receiving end, the bandwidths of the plurality of links can be the same or different, and the plurality of links can be selected from the existing links, so that the sum of the bandwidths of the selected target links is greater than or equal to the bandwidth requirement.
102, slicing the data to be transmitted according to the data size of the data to be transmitted and the bandwidth of the target link to obtain first slice data which are sequentially arranged according to a slice sequence;
after a target link is selected, a sending end counts the data size of data to be transmitted, and slices the data to be transmitted by using the data size of the data to be transmitted and the bandwidth of the selected target link to obtain first slice data which are sequentially arranged according to a slicing sequence, wherein the data to be transmitted comprises a plurality of data blocks, the data size of each data block can be the same or different, and the data to be transmitted needs to be restored at a receiving end, so that when the data to be transmitted is divided, the data are sequentially divided according to the sequence of the data blocks in the data to be transmitted, and the first slice data obtained by slicing are also sequentially arranged according to the slicing sequence. It is understood that since the size of the data block cannot be guaranteed to be an integer multiple of the slice size, there may be first slice data having a size smaller than the slice size, and for such data, the requirement for the slice size may be satisfied by way of zero padding.
103, distributing sequence numbers to the first slice data to obtain second slice data;
and step 104, sequentially sending the second slice data to a receiving end through the target link, wherein the receiving end is used for recombining the received second slice data.
In this application, a serial number is assigned to the first slice data, and the first slice data with the serial number is used as the second slice data, where the serial number is usually located at the front end of the second slice data and is carried in a byte manner. Further, the sending end sends the second slice data to the receiving end through the target links, wherein the receiving end allocates a buffer space for each target link, and the target links with large bandwidth transmit more data in the same time relative to the target links with small bandwidth, so that the buffer space allocated by the target links with large bandwidth is correspondingly large at the receiving end. After receiving the second slice data, the receiving end caches the second slice data into the corresponding cache space, and after finishing caching the data to be transmitted, the receiving end reads the second slice data from the cache space corresponding to each target link, and recombines the second slice data based on the sequence relation between the serial number and the cache time, so as to realize the recovery of the data. It can be understood that, when the receiving end reassembles the second sliced data, it is necessary to remove the sequence number in the second sliced data and then reassemble the second sliced data, that is, the data obtained after reassembly does not include a sequence number.
The sending the second slice data to the receiving end through the target link may specifically include: a transmitting end monitors a target link; and if the idle target link is monitored, sending second slice data to the idle target link. For example, if there are three target links, the first three pieces of second slice data are simultaneously sent to the three target links at the initial time, and the three target links are monitored, and if it is monitored that the third target link completes transmission, the fourth piece of second slice data are sent to the third target link, and so on, so that each target link can continuously transmit slice data, and the transmission efficiency is improved.
In the embodiment of the application, by selecting a plurality of target links, parallel transmission of second slice data can be realized by slicing the data to be transmitted, and effective recovery of the second slice data can be realized by recombining the data to be transmitted through the receiving end.
On the basis of the embodiment shown in fig. 1, please refer to fig. 2, which is a schematic flow chart illustrating a step of refining step 102 in the embodiment shown in fig. 1, and includes:
step 201, determining the maximum value and the minimum value of a data block contained in data to be transmitted;
step 202, determining the size of a slice according to the maximum value, the minimum value and the bandwidth of a target link;
and step 203, slicing the data to be transmitted according to the slice size to obtain each piece of first slice data which is sequentially arranged according to the slice sequence.
In this embodiment of the present application, the data to be transmitted includes a plurality of data blocks, the sending end sequentially traverses each data block, and determines the size of each data block to determine the maximum value and the minimum value, and determines the size of the slice according to the maximum value, the minimum value, and the bandwidth of the target link, and in a feasible implementation manner, the manner of determining the size of the slice may be: determining a difference value between the maximum value and the minimum value of the data block, when the difference value is greater than a preset threshold value, determining whether the time required by the minimum value transmitted by the target link with the minimum bandwidth is less than a preset time, if so, determining the minimum value as the size of the slice, and if so, taking the size of data which can be transmitted by the target link with the minimum bandwidth in the preset time as the size of the slice. And when the difference is smaller than a preset threshold value, taking the size of data which can be transmitted in a preset time by the target link with the minimum bandwidth as the slice size.
It can be understood that the preset time duration is set to avoid that the data transmission time after slicing is too long and is not beneficial to parallel transmission, and when the preset time duration is set, the preset time duration when the efficiency of parallel transmission is ensured to be better and the slicing is not too large or too small can be determined through an experimental mode.
It will be appreciated that when the difference is greater than the predetermined threshold, it indicates that the difference between the maximum and minimum values is large, in which case the slice size determination needs to be performed mainly on the minimum value to avoid that the data block cannot be sliced. And when the difference is smaller than the preset threshold, the difference between the maximum value and the minimum value is smaller, the sizes of the data blocks are concentrated, and at the moment, the size of the slice is determined mainly by the transmission capability of the bandwidth.
In the embodiment of the application, the size of the slice is determined by comprehensively considering the data size of the data to be transmitted and the bandwidth of the target link, so that the obtained size of the slice can be matched with the target link, and the transmission efficiency is better.
Referring to fig. 3 based on the embodiment shown in fig. 1, fig. 3 is a schematic diagram of a detailed flow of step 103 in the embodiment shown in fig. 1, which includes:
and 302, sequentially allocating sequence numbers to the first slice data according to the size of the sequence number pool to obtain second slice data.
In the embodiment of the present application, when it is considered that the data size of the data to be transmitted is large, if serial numbers are sequentially allocated according to the number of slices, the data size of the serial numbers may be too large, for example, if the number of slices is 5 ten thousand, serial numbers are sequentially allocated, the largest serial number is 49999, and the data size of the serial number is too large, which results in too much bandwidth being occupied. Therefore, in order to avoid the problem, after the sending end completes slicing, the size of the sequence number pool is also determined according to the bandwidth of the target link, and the size of the sequence number can be effectively controlled by recycling the sequence number in the sequence number pool, so that the influence of increasing the sequence number on the transmission efficiency is reduced.
One possible implementation manner for determining the size of the sequence number pool according to the bandwidth of the target link is as follows:
step A, calculating the transmission time required by each target link for transmitting one piece of second slice data;
step B, acquiring the maximum transmission time of the target link, and determining the quantity of second slice data which can be transmitted by each target link based on the maximum transmission time;
and step C, taking the total number of the second slice data which can be transmitted by each target link as the size of the sequence number pool.
In step a, the size of the piece of second slice data is preferably the slice size determined in step 202. The factors influencing the transmission time include the length of the link and the size of the bandwidth, the transmission time is the same under the condition that the link length and the bandwidth of each target link are the same, the transmission time is different under the condition that the link length or the bandwidth are different, and the delay difference exists between the links. In order to indicate that the delay is different from the storage of the second slice data with the same sequence number at the same time, which causes a problem of a reassembly error, the size of the sequence number pool needs to be determined.
Specifically, the transmission time required for transmitting data of one slice size in a plurality of target links is determined, the maximum transmission time is obtained, and the number of second slices that can be transmitted by each target link is determined based on the maximum transmission time, for example, for link ABC, the transmission time for transmitting data of one slice size in link a is the maximum and is 10s, the number of slices that can be transmitted within 10s for link B and link C is determined, and is 5 slices and 10 slices, respectively, and the total number of the number of second slices that can be transmitted by each target link is used as the size of the sequence number pool. For example, for link ABC, the number of slices that can be transmitted within 10s is 1, 5, 10, respectively, then the size of the sequence number pool can be determined to be 16.
It is to be understood that, in the case of determining the size of the sequence number pool, the initial value may be 0 or 1, for example, if the size of the sequence number pool is 10, the sequence number may be 0 to 9, or 1 to 10.
It is to be understood that, if there is a non-integer number in the determined number of second slice data that can be transmitted by each target link, based on the maximum transmission time, the size of the sequence number pool of one integer may be determined by obtaining the smallest integer. For example, if the number of slices that can be transmitted by the link ACB in 10s is 1, 2.5, 4, respectively, and the total number is 7.5, the size of the sequence number pool can be determined to be 2 times 7.5, that is, 15.
It is understood that, when determining the sequence number pool, and in order that the same retention time of different slices with the same sequence number does not occur, which causes a reassembly error, the size of the sequence number pool may be set to be greater than or equal to the number of target links, and specifically, the step C may be: calculating the total number of the second slice data which can be transmitted by each target link; and if the total number is greater than or equal to the number of the target links, determining the total number as the size of the sequence number pool.
In an application scenario, if the size of the first slice data is 120 slices, the size of the determined sequence number pool is 10, and the sequence numbers are 0 to 9, the first slice data may be first divided into groups according to 10 units, that is, 12 groups, and the sequence numbers are sequentially assigned to each group according to the sequence from 0 to 9, so as to obtain the second slice data with sequence numbers.
In the embodiment of the application, the size of the sequence number pool is determined by using the bandwidth of the target link, so that after the sequence number of the first slice data is allocated, the recombination error caused by the transmission problem can be effectively avoided.
In order to better understand the technical solution in the embodiment of the present application, please refer to fig. 4, which is a schematic diagram of a data transmission method in the embodiment of the present application, as shown in fig. 4, a sending end performs slicing and serial number allocation on data to be transmitted to obtain a plurality of second sliced data, then the sending end sends the obtained plurality of second sliced data to a receiving end through three links, the receiving end performs caching after receiving the second sliced data, and after completing receiving the data to be transmitted, the receiving end obtains the second sliced data transmitted by each link from the caching and performs reassembly to restore the original data.
