Description
Technical Field
The present invention relates to the field of data transmission technologies, and in particular, to a data transmission method, apparatus, system, and computer-readable storage medium.
Background
At present, resources on the network are quite rich, and many users can download resource data on the network to the local or upload local resources to the network through a data transmission tool.
The data transmission speed is usually determined by the network bandwidth of the device to which the data transmission tool belongs and the transmission condition of the resource data itself, and when the available uplink or downlink bandwidth of the data transmission tool is greater than the maximum transmission speed allowed by the transmission condition of the current resource data, the transmission speed of the resource data is the optimal speed, that is, the maximum transmission speed of the resource data. If the device to which the data transfer tool belongs still has spare bandwidth, this part of bandwidth is wasted.
In order to make full use of the bandwidth of the system, when a plurality of tasks exist, the user can select the plurality of tasks to be transmitted simultaneously, so that the plurality of tasks are completed concurrently, and the overall downloading time of all the tasks is saved.
In the existing multi-task simultaneous transmission function, a system defaults (a user can also set) the maximum task number to be transmitted simultaneously, when the total amount of tasks to be transmitted is within the range of the maximum task number, all tasks are downloaded or uploaded simultaneously, namely all tasks are downloaded or uploaded in parallel, and when the total amount of tasks to be transmitted exceeds the range of the maximum task number, the tasks exceeding the maximum task number are queued to wait for transmission.
Because the bandwidth is fully utilized by adjusting the maximum task number transmitted simultaneously, actually, the transmission speed of each task is different, and the speed in the process of transmitting one task fluctuates, the bandwidth occupation situation may be different even if the tasks with the same number are the same, and it cannot be completely ensured that each group of tasks with the maximum task number can fully utilize the system bandwidth.
Therefore, how to ensure that the system bandwidth is fully utilized when performing a data transmission task is a problem that needs to be solved urgently by those skilled in the art.

It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
It should be noted that the description relating to "first", "second", etc. in the present invention is for descriptive purposes only and is not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.
The application provides a data transmission method, a data transmission device, a data transmission system and a computer readable storage medium, which are used for solving the problem that the system bandwidth cannot be fully utilized when a data transmission task is carried out in the prior art.
Referring to fig. 1, fig. 1 is a schematic flow chart according to an embodiment of the invention.
In one embodiment, the method comprises the following steps:
s101, monitoring the speed sum of all currently ongoing data transmission tasks.
In the present scheme, the data transmission task is a data download task or a data upload task, and it can be understood that if the data transmission task in this step is a data download task, the data transmission in the subsequent step is a data download operation, and if the data transmission task in this step is a data upload task, the data transmission in the subsequent step is a data upload operation.
It should be noted that the data transmission speed may also be understood as an uplink bandwidth rate or a downlink bandwidth rate corresponding to data uploading or data downloading, and the bandwidth rate and the occupied bandwidth may be converted with each other. Theoretically, 2M bandwidth, i.e., 2Mb/s, the theoretical rate of the wideband is 256KB/s, and the actual rate is about 103-200 kB/s; 4M bandwidth, i.e. 4Mb/s, the theoretical rate of the wideband is 512KB/s, and the actual rate is about 200-440 kB/s. The reason is caused by the influence of a plurality of factors such as user computer performance, network equipment quality, resource use condition, network peak period, website service capability, line attenuation, signal attenuation and the like.
The sum of the speeds of all the current data uploading tasks can reflect the bandwidth occupied by all the current uploading tasks, and the sum of the speeds of all the current data downloading tasks can reflect the bandwidth occupied by all the current downloading tasks, so that the sum of the speeds is directly utilized to adjust the number of the tasks which are transmitted at the same time.
Specifically, the sum of the speeds of all currently ongoing data transmission tasks is monitored first, and since the speed of data transmission fluctuates normally, real-time monitoring is not necessary, which results in a great waste of computing resources, so that the monitoring operation may be performed once at preset time intervals, for example, once at 30s intervals.
For example, if there are 3 current download tasks, the first speed is 20kb/s, the second speed is 30kb/s, and the third speed is 20kb/s, the sum of the speeds of the current download tasks is 70 kb/s.
S102, if the speed sum is lower than a preset speed threshold value and data transmission tasks waiting for transmission exist, determining at least one newly added data transmission task in the data transmission tasks waiting for transmission and performing data transmission.
In the scheme, a preset speed threshold is determined for all currently available uplink bandwidths or downlink bandwidths of the data transmission tool according to a conversion rule of bandwidth and bandwidth rate, and it can be understood that if the sum of the speeds of all current data transmission tasks reaches the preset speed threshold, it indicates that the current data transmission task has fully utilized the bandwidth corresponding to the preset speed threshold, and otherwise, an idle bandwidth can be utilized.
If the sum of the speeds of all the current data transmission tasks is lower than the preset speed threshold, it is proved that the idle bandwidth can be utilized, so that a new data transmission task is determined from the data transmission tasks waiting for transmission, and the new data transmission task is started to be transmitted, that is, the number of the current data transmission tasks is increased.
Therefore, the method and the device for data transmission are characterized in that the speed sum of all current data transmission tasks is monitored, whether the speed sum is lower than a preset speed threshold value or not is judged, and if yes, a new data transmission task is determined and transmission is started. Because the speed can reflect the bandwidth condition, the sum of the speeds can reflect the bandwidth condition occupied by all the data transmission tasks, and the preset speed threshold can reflect the total quantity of the preset available bandwidth, the current bandwidth can be more fully utilized by adjusting the total quantity of the current data transmission tasks by the speed, and the completion rate of all the data transmission tasks can be more effectively improved.
A specific data transmission method provided in the embodiments of the present application is introduced below, and a data transmission method described below and the embodiments described above may be referred to each other.
Referring to fig. 2, a data transmission method provided in an embodiment of the present application specifically includes:
s201, monitoring the sum of the speeds of all currently ongoing data transmission tasks.
S202, if the sum of the speeds is lower than a preset speed threshold value and a data transmission task waiting for transmission exists, network speed measurement is carried out, and the current actual available speed is determined by using a network speed measurement result.
It should be noted that, because the preset speed threshold is set by the user, the preset speed threshold set by the user may not be in accordance with the actual uplink bandwidth or downlink bandwidth of the current computer; in addition, the network condition of the user may also be unstable, so that when the data transmission speed corresponding to the actual uplink bandwidth and downlink bandwidth is less than the preset speed threshold set by the user, the sum of the speeds is always lower than the preset speed threshold, and at this time, the number of tasks transmitted simultaneously is continuously increased, so that the number of tasks transmitted in parallel is too large, the actually occupied bandwidth is not changed, and the overall completion time is not changed, but the time for completing a single task is longer, which is not in accordance with the actual expectation of the user.
Therefore, in order to avoid such a situation, when the sum of the speeds of all the data transmission tasks is lower than the preset speed threshold, the tasks transmitted simultaneously are not increased, but it is necessary to further determine whether the current preset speed threshold matches the actual network speed.
Specifically, firstly, network speed measurement is performed on the current system, and the actually available speed of the current system is determined.
It should be noted that, in the prior art, network speed measurement has been implemented, and only relevant tools need to be called in the scheme, and the specific speed measurement scheme is not described again.
S203, judging whether the actual available speed is greater than the preset speed threshold value.
After the current actual available speed sum is measured, whether the actual available speed sum is larger than a preset speed threshold value or not can be judged, if yes, S204 is executed again, and a new task is added.
And S204, if so, determining at least one newly added data transmission task in the data transmission tasks waiting for transmission and performing data transmission. In a preferred embodiment, if the sum of the actual available speeds is not greater than the preset speed threshold, the preset threshold may be automatically adjusted to match the current network condition, which is more accurate.
Specifically, when the actual available speed is not greater than the preset speed threshold, the preset speed threshold is adjusted according to the actual available speed.
In a specific embodiment, a function of whether to allow the data transmission tool to automatically adjust the preset speed threshold may be provided for a user, and therefore, before the adjusting the preset speed threshold according to the actual available speed sum, the method further includes:
judging whether the preset speed threshold value has an adjustment authority or not;
if yes, continuing to execute the step of adjusting the preset speed threshold according to the actual available speed.
In this step, if the user selects to allow the data transmission tool to automatically adjust the preset speed threshold, the adjustment permission of the preset speed threshold may be obtained, and the adjustment operation is performed, otherwise, the adjustment operation is not performed.
Therefore, before adding a new task and transmitting data, whether the current actual available speed is greater than a preset speed threshold value needs to be judged, if so, the new task is added, and otherwise, the new task is not added. Therefore, the situation that when the data transmission speed corresponding to the actual bandwidth is smaller than the preset speed threshold set by the user, the number of tasks transmitted simultaneously is continuously increased, the number of tasks transmitted in parallel is excessive, the actual occupied bandwidth is unchanged, the overall completion time is unchanged, the completion time of a single task is longer, and the actual completion time is inconsistent with the actual expectation of the user can be avoided.
A specific data transmission method provided in the embodiments of the present application is introduced below, and a specific data transmission method described below may be mutually referred to any of the embodiments described above.
Referring to fig. 3, a specific data transmission method provided in the embodiment of the present application specifically includes:
s301, the sum of the speeds of all the currently ongoing data transmission tasks is monitored.
S302, if the speed sum is lower than a preset speed threshold value and data transmission tasks waiting for transmission exist, determining at least one newly added data transmission task in the data transmission tasks waiting for transmission and performing data transmission.
S303, detecting whether the speed reduction value of the original data transmission task is larger than a preset threshold value.
It should be noted that, if the data transmission speed corresponding to the actual bandwidth is smaller than the preset speed threshold set by the user, even if a new task is added, the sum of the speeds will not increase any more, and only the speed of each task being transmitted will be reduced, which causes the problem that the completion time of a single task is long, and is not in accordance with the actual expectation of the user.
In order to avoid the situation, the transmission speed of each task can be detected after a new task is added.
Specifically, it is detected whether the speed reduction value of the original data transmission task is greater than a preset threshold, where the preset threshold is used to determine whether the reduction degree of the transmission speed of the original data transmission task exceeds the expectation of a user, and the preset threshold may be set according to an actual situation, and the scheme is not specifically limited.
The original data transmission task is a task which is transmitted before a new data transmission task is determined and transmitted in the tasks waiting for data transmission.
In a specific embodiment, a first average speed of the original data transmission task is determined; the first average speed is the average transmission speed of each original data transmission task within a preset time range after the newly added data transmission task starts to be performed;
determining a second average speed of the original data transmission task; the second average speed is the average value of the transmission speed of each original data transmission task within a preset time range before the newly added data transmission task starts to be carried out;
and judging whether the reduction value of the first average speed compared with the second average speed is greater than a preset threshold value or not.
It should be noted that, because the data transmission speed is not a stable speed, and even the fluctuation is very large, the detection result may not be accurate by using the instantaneous speed, and in order to improve the accuracy of the detection result, the average value of the speed in the unit time is used for the detection in the present scheme.
Specifically, the first average speed corresponds to a newly-added data transmission task and is a speed average value within a first preset time range after the newly-added data transmission task starts to be performed; the second average speed corresponds to the original data transmission task, and is the speed average value of the original data transmission task in a second preset time range before the newly-added data transmission task starts.
The first preset time and the second preset time can be set according to actual conditions, and the scheme is not particularly limited.
And S304, if yes, suspending the newly added data transmission task.
Specifically, if the speed reduction value of the original data transmission task is detected to be larger than the preset threshold value, the newly-added data transmission task is suspended, so that the problem that the completion time of a single task is long and the problem that the completion time is inconsistent with the actual expectation of a user is solved.
Further, the embodiment also discloses a data transmission device.
