The data writing method can be writing in by a client through a wired network or a wireless network, and the server monitors the written data in real time to acquire the data writing amount within the preset time. The preset time and the data writing method are not particularly limited in the embodiments of the present invention, and those skilled in the art can determine the preset time and the data writing method according to actual situations.
S12: and when the data writing amount in the preset time is less than or equal to the preset flow threshold value, acquiring the residual buffer space of the buffer.
Illustratively, the preset traffic threshold is 3BP/5min, i.e. 3 cache slices per 5 minutes. The preset flow threshold value is not specifically limited in the embodiment of the present invention, and a person skilled in the art can set the preset flow threshold value according to actual conditions.
After the data write-in quantity within the preset time is obtained, flow early warning is carried out on the obtained data write-in quantity, namely the data write-in quantity within the preset time is compared with a preset flow threshold value, when the data write-in quantity within the preset time is larger than the preset flow threshold value, the data write-in speed is higher at the moment, a large amount of data are written into a cache, an advance burning request is sent to burning equipment (such as an optical disk drive, a hard disk connected with a server and the like) at the moment, the existing cache is released as soon as possible, so that the early warning can be carried out even if an extreme situation of writing in a large amount of flow is encountered, the existing cache is released as soon as possible, the cache is guaranteed not to be fully.
When the data writing amount in the preset time is smaller than or equal to the preset flow threshold, which indicates that the data writing speed is slow at the moment, obtaining the residual cache space of the cache, adjusting the current data writing speed according to the residual cache space of the cache, and obtaining the residual cache space of the cache by calling a related function.
S13: and adjusting the current data writing speed according to the size of the residual cache space.
For example, the adjusting the current data writing speed according to the size of the remaining cache space may specifically be: and when the residual cache space is smaller than a first preset threshold, performing data writing at a first preset speed, wherein the first preset speed is smaller than the current data writing speed.
Illustratively, the first preset threshold may be 20%, and the first preset threshold is not specifically limited in the embodiment of the present invention and may be determined by a person skilled in the art according to the specific situation of the buffer. The first preset speed may be set in advance, for example, 30 MB/S; it can also be dynamically adjusted according to the specific remaining space, for example, when the remaining space is 1%, the current data writing speed is reduced to 3M/S; the method for determining the first preset speed is not particularly limited in the embodiment of the present invention, and may be determined by a person skilled in the art according to actual conditions.
And when the residual cache space is larger than a second preset threshold, performing data writing at a second preset speed, wherein the second preset speed is larger than the current data writing speed, and the second preset threshold is larger than the first preset threshold.

The second preset speed may be set in advance, for example, 80 MB/S; the current data writing speed can also be adjusted dynamically according to the specific remaining space, for example, when the remaining space is 80%, the current data writing speed is adjusted to be 100M/S; the method for determining the second preset speed in the embodiment of the present invention is not particularly limited, and those skilled in the art may determine the second preset speed according to actual situations.
According to the data writing speed determining method provided by the invention, the data writing amount in the preset time is obtained, when the data writing amount in the preset time is smaller than or equal to the preset flow threshold value, the residual cache space of the cache is obtained, and the current data writing speed is adjusted according to the size of the residual cache space. According to the invention, by comparing the data writing amount of the preset time with the preset flow threshold value, when the data writing amount of the preset time is less than or equal to the preset flow threshold value, the current data writing speed is adjusted according to the size of the residual space of the buffer, so that the long-term stable adjustment of the service buffer can be realized, the buffer cannot be fully written, and the server is ensured to be always in an available state.
As an optional implementation manner of the embodiment of the present invention, the step S13 further includes:
firstly, when the residual cache space is greater than or equal to a first preset threshold and the residual cache space is less than or equal to a second preset threshold, obtaining the average value of the writing speeds of the historical data.
For example, since the current recording instantaneous speed cannot be determined, the average value of the historical data writing speed can be used as a reference, and the current data writing speed can be adjusted according to the reference.
The average value of the history data writing speeds may be an average value of data writing speeds of a previous period of time (for example, a previous week) or an average value of data writing speeds of previous times (for example, previous 5 times). The average value of the historical data writing speed is not particularly limited in the embodiment of the present invention, and can be determined by a person skilled in the art according to actual situations.
Taking the example that the average value of the history data writing speed is the average value of the data writing speed of the previous week, a specific determination method of the average value of the history data writing speed is described, namely, the data writing amount of the previous week is obtained, and then the average speed of the data written in the previous week, namely the history data writing speed, is calculated by using an average value calculation formula.
And when the average value of the historical data writing speeds is less than the current data writing speed, adjusting the current data writing speed to be the historical data writing speed. And when the average value of the historical data writing speeds is greater than or equal to the current data writing speed, writing data at the current data writing speed.
According to the embodiment of the invention, by dynamically monitoring the method for limiting the flow, the rapid experience when the residual space is abundant is ensured, and the current writing speed is adjusted according to the average value of the historical data writing speed, so that a user can obtain relatively better use experience when writing and recording equipment, and the use is more stable and efficient.
As an optional implementation manner of the embodiment of the present invention, after the step S13 adjusts the current data writing speed, the data writing speed determining method further includes:
first, a response timing operation.

And secondly, when the time interval reaches a preset duration, repeatedly executing the steps from obtaining the data writing amount in the preset time to determining the data writing speed according to the size of the residual cache space.
The preset time period is exemplarily 10 minutes, and the preset time period is not particularly limited in the embodiment of the present invention and can be determined by a person skilled in the art according to actual situations.
After the current data writing speed is adjusted, the resource occupation condition of the server needs to be monitored in real time, and when the time interval reaches the preset time length, the steps of obtaining the data writing amount in the preset time and determining the data writing speed according to the size of the residual cache space are repeatedly executed to readjust the data writing speed so as to ensure the long-term stable adjustment of the service cache and enable the server to be always in an available state.
