Description

Buffer capacity adjustment method and device

Technical Field

The present disclosure relates to the field of internet technologies, and in particular, to a method and an apparatus for adjusting a buffer capacity.

Background

With the rapid development of internet technology, the internet technology is closely related to the work and life of people, and a large amount of data transmission is often involved to meet the needs of the work and life of people. Generally, a data transmitting end and a data receiving end have a transmission buffer and a reception buffer when transmitting data. The sending buffer area and the receiving buffer area are used for temporarily buffering data which is not sent or received, and if the data amount buffered in the sending buffer area or the receiving buffer area is greatly changed, the capacity of the sending buffer area or the receiving buffer area needs to be adjusted.

In the prior art, the capacity of the buffer area can be automatically and dynamically adjusted through an operating system; alternatively, the monitoring personnel can estimate the required buffer capacity, and then directly set the buffer capacity by calling the application program interface of the operating system. However, by means of automatic adjustment of the operating system, the monitoring personnel cannot know the adjustment process of the buffer area capacity, that is, cannot manually monitor the change of the buffer area capacity, which may cause that the buffer area capacity cannot adapt to the change of the data amount, and thus some data is missed. In addition, the monitoring personnel manually invokes the application program interface of the system to set, the operating system can directly set the buffer capacity as a fixed value, and simultaneously, the function of automatically adjusting the buffer capacity is closed, that is, the size of the buffer capacity is artificially limited, so that the buffer capacity is fixed, and if the monitoring personnel erroneously estimates the required buffer capacity, the set buffer capacity can not adapt to the change of the data quantity. And thus a simpler and more convenient method for performing buffer capacity adjustment operations or processes is needed.

First, terms related to one or more embodiments of the present specification will be explained.

TCP (Transmission Control Protocol ): is a connection-oriented, reliable Transport layer (Transport layer) communication protocol based on byte streams that performs the functions specified by the fourth Transport layer in the simplified OSI model of computer networks. TCP aims to accommodate a layered protocol hierarchy supporting multiple network applications, relying on TCP to provide reliable communication services between pairs of processes in host computers connected to different but interconnected computer communication networks.

Socket: sockets, which are abstractions of endpoints that perform two-way communication between application processes on different hosts in a network, are one end of a process communication on the network, and provide a mechanism for application layer processes to exchange data using a network protocol. In terms of the position, the socket is connected with the application process in an upper mode, and the socket is connected with the network protocol stack in a lower mode, so that the socket is an interface for the application program to communicate through the network protocol, and is an interface for the application program to interact with the network protocol root.

And (3) a kernel: is the most basic part of an operating system, which is a piece of software that provides many applications with secure access to computer hardware, where access is limited, and the kernel decides how long a program is operating on a piece of hardware. The kernel is a core of an operating system, is a first layer of software expansion based on hardware, provides the most basic function of the operating system, is a basis for the operating system to work, and is responsible for managing the process, the memory and the kernel architecture of the system to determine the performance and the stability of the system.

API (Application Programming Interface, application program interface): is a predefined function or convention that refers to the engagement of various components of a software system to provide a set of routines that an application and developer can access based on certain software or hardware without having to access source code or understand the details of the internal operating mechanism.

Operating System (OS): the system is a computer program for managing computer hardware and software resources, and is an interface between a user and a computer hardware system, and an operating system needs to process basic transactions such as managing and configuring memory, determining the priority of supply and demand of system resources, controlling input equipment and output equipment, operating network, managing file systems and the like. The operating system also provides an operation interface for the user to interact with the system, and the user can quickly, effectively, safely and reliably operate various resources in the computer system by the aid of the operating system so as to process own programs.

In the present specification, a buffer capacity adjustment method is provided, and the present specification relates to a buffer capacity adjustment apparatus, a computing device, and a computer-readable storage medium, which are described in detail one by one in the following embodiments.

Fig. 1 shows a flowchart of a buffer capacity adjustment method according to an embodiment of the present disclosure, which specifically includes the following steps:

step 102: and receiving a first call instruction of the first application program interface, wherein the first call instruction carries the reference capacity of the buffer area.

In practical applications, in order to realize data transmission between end-to-end, many transmission protocols, such as TCP, have been generated for end-to-end data transmission. Since there are 2 spaces, such as a user space and a kernel, in an operating system, the data transmitting end and the data receiving end both include the user space and the kernel. The kernel is the most basic part of the operating system, can control the hardware resources of the computer, and provides an environment for the upper layer application program to run.

When end-to-end data transmission is performed through the TCP protocol, a sending buffer area and a receiving buffer area exist after the TCP socket is connected in the kernel of the data sending end and the kernel of the data receiving end. The data to be pushed can be temporarily cached in the receiving buffer area first, and is waited for the application program to read, if the application program does not read the data in the receiving buffer area all the time, the data to be pushed can be always stored in the data buffer area. If the application program does not read the data in the receiving buffer for a long time, or if the buffered data to be pushed in the receiving buffer is more, the capacity of the receiving buffer needs to be adjusted.

At present, the buffer capacity can be automatically and dynamically adjusted through an operating system, but monitoring staff cannot know the adjusting process of the buffer capacity, namely, the change of the buffer capacity cannot be monitored manually, the buffer capacity can not adapt to the change of the data quantity, and therefore certain data are missed; or, the monitoring personnel can estimate the required buffer capacity, and then directly set the buffer capacity by calling the application program interface of the operating system, but the size of the buffer capacity is artificially limited, so that the buffer capacity is fixed, and if the monitoring personnel erroneously estimates the required buffer capacity, the set buffer capacity can not adapt to the change of the data quantity.

Therefore, in order to facilitate monitoring personnel to monitor the capacity of the buffer zone in real time and ensure that the capacity of the buffer zone can adapt to the change of the data volume in the actual application scene, the specification provides a buffer zone capacity adjusting method, which can receive a first calling instruction of a first application program interface, wherein the first calling instruction carries the reference capacity of the buffer zone; then setting the buffer capacity to the reference capacity; then, according to the data amount cached in the buffer area, whether the reference capacity is adjusted or not can be determined; and displaying the adjustment information of the reference capacity when the adjustment of the reference capacity is detected. Therefore, the buffer zone can be provided with a fixed reference capacity, the set reference capacity can be dynamically adjusted in real time after the buffer zone is provided with the fixed reference capacity, and the adjustment condition of the buffer zone capacity can be displayed, so that monitoring personnel can monitor the buffer zone capacity conveniently, and a coping strategy can be made in real time.

Specifically, the first application program interface is an API interface newly added in the operating system, and is used to set the reference capacity for the buffer. The monitoring personnel can realize the setting of the buffer capacity by calling the first application program interface. The first calling instruction is an instruction triggered by the monitoring personnel through calling the corresponding operation of the API interface, and the operating system can receive the first calling instruction to call the first application program interface, so that the capacity of the buffer area is set. The reference capacity is a capacity of the buffer which is empirically determined in advance in most cases.

In an optional implementation manner of this embodiment, the buffer capacity condition may also be displayed in real time, and the specific implementation process is as follows:

In specific implementation, the kernel source code can be modified to display the capacity of the buffer area. It should be noted that, although the description of the related content showing the capacity of the buffer is described below in step 102, the whole data pushing process, including the subsequent automatic and manual adjustment processes of the capacity of the buffer, may display the capacity of the buffer.

In the specification, after the buffer area is created, the capacity condition of the buffer area can be displayed in real time, so that monitoring personnel can monitor in real time, and further whether the capacity of the buffer area needs to be manually interfered by calling an application program interface or not is determined.

Step 104: the buffer capacity is set to the reference capacity.

Specifically, a first call instruction of a first application program interface is received, and the buffer capacity is further set to be the reference capacity on the basis that the first call instruction carries the reference capacity of the buffer.

It should be noted that, generally, when creating the buffer, there is an initial capacity, which may not be suitable for the data amount in most cases, that is, frequent dynamic adjustment of the capacity of the buffer may be required, and in order to avoid frequent dynamic adjustment of the capacity of the buffer, a reference capacity may be set for the buffer by calling a newly added API interface (i.e., the first application program interface), and the reference capacity may be suitable for the data amount in the conventional cases.

For example, if the initial capacity of the operating system created the buffer is 5, it may happen that the buffer capacity is adjusted in real time based on the amount of data only, the amount of data is first increased by a small fraction, the buffer capacity is adjusted to 7, then the amount of data is increased by a small fraction, the buffer capacity is adjusted to 10, and then the amount of data is increased by a lot, at which time the buffer capacity is adjusted to 15. In most cases, it is basically necessary to adjust the buffer capacity to around 15 at each time. To avoid frequent adjustment of the buffer capacity, the buffer capacity can be set to 15 directly by calling the first application program interface.

According to the method, the monitoring personnel can monitor the size of the buffer zone capacity in real time, and through manually triggering the first calling instruction, the operating system can call the first application program interface under the condition that the first calling instruction is received, the buffer zone capacity is set to be the reference capacity, the buffer zone capacity is prevented from being frequently adjusted, and processing resources of the operating system are saved.

Step 106: and determining whether to adjust the reference capacity according to the data quantity cached in the buffer zone.

Specifically, on the basis of setting the buffer capacity as the reference capacity, further, whether to adjust the reference capacity is determined according to the data amount buffered in the buffer. That is, after a fixed reference capacity is set for the buffer, it is determined whether real-time dynamic adjustment of the set reference capacity is required (i.e., whether real-time dynamic adjustment of the buffer capacity is required).

It should be noted that, the data buffered in the buffer area is not constant, that is, the data amount buffered in the buffer area is increased or decreased continuously, when the data amount buffered is increased, the buffer area needs to be expanded to ensure that each data can be buffered and data cannot be missed; when the amount of data buffered becomes small, the buffer size needs to be reduced in order to save resources and avoid excessive redundancy. Therefore, in the present specification, it can be determined whether the current buffer capacity needs to be enlarged or reduced according to the data amount buffered in the buffer, so as to adapt to the data buffering requirements of different time periods. Since the buffer capacity can be set to the reference capacity through the received first call instruction, it is actually determined whether to adjust the current buffer capacity according to the data amount buffered in the buffer.

In an optional implementation manner of this embodiment, according to the amount of data buffered in the buffer, it is determined whether to adjust the reference capacity, and the specific implementation process may be as follows:

Specifically, the preset period of time is a period of time for calculating the rate of change of the data amount, and the smaller the preset period of time is, the more accurate the calculated rate of change of the data amount is, for example, the preset period of time may be 0.5 seconds, 1 second, 2 seconds, or the like.

In practical application, the capacity of the buffer area is generally expanded when the capacity of the buffer area is insufficient or the capacity of the buffer area is about to be insufficient, and the capacity of the buffer area is reduced when the redundancy of the capacity of the buffer area is relatively large, so that the dynamic adjustment of the capacity of the buffer area is not timely enough. The data volume change rate of the buffer area in a period of time can reflect the increasing or decreasing trend of the subsequent data volume, so that the buffer area capacity requirement can be reflected in advance, and therefore the buffer area capacity can be dynamically adjusted according to the data volume change rate of the buffer area in a preset period of time in the specification, that is, the change trend of the data volume in the buffer area can be predicted through the data volume change rate of the buffer area, and the buffer area capacity can be adjusted in advance.

In an optional implementation manner of this embodiment, the determining the rate of change of the data amount of the buffer area in the preset time period may be implemented as follows:

The data amount at the start time and the end time in the preset time period can be obtained respectively, and the change rate of the data amount can be calculated through the difference of the data amounts. In particular, when determining the first data amount of the buffered data at the start time and the second data amount of the buffered data at the end time of the preset time period, the slope of the line connecting the second data amount and the first data amount may be determined as the data amount change rate of the buffer.

Fig. 2 is a schematic diagram of a change of the data amount of the buffer in a preset time period, as shown in fig. 2, where the preset time period is 1 second, and the current time is assumed to be 8:00 seconds, the starting time of the preset time period is 7:59 seconds, the end time of the preset time period is 8:00 seconds. Suppose 7: the first amount of buffered data at 59 seconds is 5,8: the second data amount of the buffer data is 10 at 00 seconds, the first data amount 5 and the second data amount 10 are connected to form a line segment, the slope of the line segment is 5, and then the change rate of the data amount of the buffer area is 5.

In an optional implementation manner of this embodiment, according to the data volume change rate, it is determined whether to adjust the buffer volume, and the specific implementation process may be as follows:

Specifically, the first change rate threshold and the second change rate threshold may be set in advance, so as to determine a change amplitude of the data amount in the preset time period. The first change rate threshold value and the second change rate threshold value may be the same or different.

Since the data amount change rate is the slope of the line connecting the second data amount and the first data amount, it is described that the data amount change rate is an increasing rate if the data amount change rate is a positive number, and that the data amount change rate is a decreasing rate if the data amount change rate is a negative number. In addition, since the data amount change rate is negative when the data amount change rate is the reduction rate, it is then determined whether the data amount change rate is greater than the second change rate threshold, and the absolute value of the actual data amount change rate is used when the buffer capacity is reduced according to the data amount change rate.

In the specification, if the data amount change rate is an increase rate, it is described that the data amount change rate of the buffer area is in an increase state in a preset time period; if the data volume change rate is the reduction rate, the data volume change rate of the buffer area in the preset time period is indicated to be in a reduction state. When the change rate of the data volume of the buffer area is in an increasing state within a preset time period and the change rate is large, the data volume to be buffered of the subsequent buffer area can be known to be greatly increased, so that the size of the buffer area needs to be expanded to buffer more data; when the change rate of the data volume of the buffer area in the preset time period is in a reduced state and the change rate is large, the data volume required to be buffered in the subsequent buffer area can be known to be greatly reduced, so that the size of the buffer area is required to be reduced, and excessive redundancy of the buffer area is avoided.

In an optional implementation manner of this embodiment, the expanding the buffer capacity according to the data volume change rate may be implemented as follows:

In particular, when it is determined that the rate of change of the data amount is large, only a large change of the data amount in the subsequent buffer area can be predicted, but it is not known how much or how much the buffer area capacity is to be enlarged or reduced, and therefore, in this specification, a correspondence between the rate of change and the capacity adjustment value may be preset, and the relationship between the rate of change and the capacity adjustment value is agreed in advance, so that after the rate of change of the data amount is determined, a corresponding target capacity adjustment value may be determined to adjust the buffer area capacity.

In addition, for the case of increasing the data amount and the case of shrinking, the adjustment of the buffer capacity may be the same or different; that is, a correspondence relationship between a change rate and a capacity adjustment value may be set in advance, and for both the case of increasing the data amount and the case of decreasing the data amount, the corresponding target adjustment value may be determined according to the correspondence relationship, or for the case of increasing and the case of decreasing, the correspondence relationship between a change rate and a capacity adjustment value may be set, respectively, which is not limited in this specification.

For example, the correspondence between the preset change rate and the capacity adjustment value is shown in the following table 1, and assuming that the determined change rate of the data amount is 5 and the first change rate threshold is 3, it is indicated that the change rate of the data amount is an increasing rate and is greater than the first change rate threshold, and the corresponding target capacity adjustment value is determined to be adjusted 10 according to the table 1, and at this time, the current buffer capacity is enlarged by 10; assuming that the determined data volume change rate is-3 and the first change rate threshold is 1, the data volume change rate is indicated to be a reduction rate and is larger than the second change rate threshold, and a corresponding target capacity adjustment value is determined to be an adjustment value 5 according to table 1, and at this time, the current buffer capacity is reduced by 5.

Table 1 correspondence table between change rate and capacity adjustment value

In an optional implementation manner of this embodiment, the first application program interface may be used to set not only the reference capacity for the buffer area, but also an upper limit value of the buffer area capacity, that is, the first call instruction may also carry the upper limit capacity of the buffer area; at this time, after expanding the buffer capacity according to the data amount change rate, the method further includes:

If the buffer area capacity after expansion exceeds the upper limit capacity, the buffer area is likely to be abnormal, and at the moment, an alarm message is generated and displayed to remind that the abnormality is likely to occur. After the monitoring personnel call the first application program interface in the specification, the reference value of the buffer zone capacity can be set, the upper limit value of the buffer zone capacity can be set, and when the buffer zone capacity exceeds the upper limit value, warning information can be generated and displayed to warn, so that the monitoring personnel can timely handle abnormal conditions.

Step 108: and displaying the adjustment information of the reference capacity when the adjustment of the reference capacity is detected.

Specifically, after determining whether to adjust the reference capacity according to the data amount cached in the buffer area, further, when detecting that the adjustment of the reference capacity occurs, displaying adjustment information of the reference capacity.

In practical application, when the reference capacity is detected to be adjusted, that is, the current buffer capacity is changed, the adjustment information of the reference capacity is the adjustment information of the buffer capacity, and the adjustment information of the buffer capacity may include the buffer capacity before adjustment and the buffer capacity after adjustment, and after the buffer capacity is adjusted, the specific condition of adjustment may be displayed, so that a monitoring person may monitor the buffer capacity, thereby immediately making a coping strategy.

It should be noted that, in the present specification, the user may manually set the buffer capacity by calling the first application program interface (i.e. the newly added API interface); and the operating system can also automatically adjust the capacity of the buffer zone according to the data quantity cached in the buffer zone and display the adjustment information of the capacity of the buffer zone. That is, in this specification, the buffer capacity can be automatically adjusted by the operating system in combination with manually invoking an Application Program Interface (API) to adjust the buffer capacity, and the buffer capacity adjustment process is visualized.

In an optional implementation manner of this embodiment, after setting the buffer capacity to the reference capacity, the method further includes:

the buffer capacity is set to the target buffer capacity.

Specifically, the second application program interface is an API interface built in the operating system, and is used to set a fixed capacity for the buffer. The monitoring personnel can realize the setting of the buffer capacity by calling the second application program interface. The second call instruction is an instruction triggered by the monitoring personnel through calling the corresponding operation of the API interface, and the operating system can receive the second call instruction to call the second application program interface, so that the capacity of the buffer area is set. The target buffer capacity is the buffer capacity that needs to be set specifically when a special situation occurs.

It should be noted that, in the present specification, the capacity attribute information of the buffer capacity may be displayed in real time, and the adjustment information of the buffer capacity may be displayed when the buffer capacity is adjusted, so that a monitoring person may monitor the buffer capacity in real time, and when an emergency or a special situation occurs, the monitoring person may call the second application program interface to set the buffer capacity as the target buffer capacity, so as to call an emergency or a special requirement.

The buffer capacity adjustment method provided by the specification can receive a first call instruction of a first application program interface, wherein the first call instruction carries the reference capacity of a buffer; then setting the buffer capacity to the reference capacity; then, according to the data amount cached in the buffer area, whether the reference capacity is adjusted or not can be determined; and displaying the adjustment information of the reference capacity when the adjustment of the reference capacity is detected. In this case, a reference capacity can be set for the buffer area by calling the first application program interface, then the operating system can automatically and dynamically adjust the reference capacity (i.e. the current buffer area capacity) according to the data volume change rate of the buffer area in the actual application scene, and in this process, if an emergency or special situation occurs, the monitoring personnel can call the second application program interface to set the current buffer area capacity as the target buffer area capacity. That is, a fixed reference capacity can be set for the buffer area, and after the fixed reference capacity is set for the buffer area, the set reference capacity can be dynamically adjusted in real time, and the buffer area capacity is not fixed, so that the buffer area capacity can be more suitable for the change of data volume in an actual application scene, and after the buffer area capacity is dynamically adjusted, the adjustment condition of the buffer area capacity can be displayed, so that monitoring personnel can monitor the buffer area capacity conveniently, a coping strategy can be made in real time, the whole buffer area capacity adjustment process can be monitored, set and adjusted, the automatic adjustment of an operating system is combined with the manual control of the monitoring personnel, and the method is simple and easy to implement, and can adapt to most data pushing scenes in the actual scene.

That is, a fixed reference capacity can be set for the buffer area, and after the fixed reference capacity is set for the buffer area, the set reference capacity can be dynamically adjusted in real time, and the buffer area capacity is not fixed, so that the buffer area capacity can be more suitable for the change of data volume in an actual application scene, and after the buffer area capacity is dynamically adjusted, the adjustment condition of the buffer area capacity can be displayed, so that monitoring personnel can monitor the buffer area capacity conveniently, a coping strategy can be made in real time, the whole buffer area capacity adjustment process can be monitored, set and adjusted, the automatic adjustment of an operating system is combined with the manual control of the monitoring personnel, and the method is simple and easy to implement, and can adapt to most data pushing scenes in the actual scene.
