Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, not all of the embodiments. The components of the embodiments of the present disclosure, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present disclosure, presented in the figures, is not intended to limit the scope of the claimed disclosure, but is merely representative of selected embodiments of the disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the disclosure without making creative efforts, shall fall within the protection scope of the disclosure.
Research shows that important request data are generally directly released and unimportant request data are intercepted when flow control is performed in the related art, and if the unimportant request data are intercepted for a long time, the corresponding threads can be closed by mistake due to the fact that the threads cannot receive the data, and normal processing of the data is further influenced.
Or when the flow control is carried out, the thread corresponding to the unimportant request is cached in the thread pool for carrying out the delay processing, but in this case, when the delay expires, the request of the delay processing must be processed, and at this time, the problem of long network delay caused by too many requests still can be caused.
Or, when flow control is performed, the application program can accurately calculate the bandwidth required by the read function and the write function of each socket, but because there may be a plurality of requests corresponding to each socket and the current concurrent request cannot be estimated, the total bandwidth required currently cannot be estimated, and thus unified scheduling of a plurality of sockets cannot be realized.
Based on the above research, the present disclosure provides a flow control method, apparatus, computer device, and storage medium, which may determine a first request requiring speed limit processing and a second request not requiring speed limit processing when detecting that a network condition satisfies a preset condition, and may directly respond to or process the second request not requiring speed limit processing; for the first request, the bandwidth limit can be determined based on the required bandwidth corresponding to the second request and the current transmission bandwidth, and the speed limit processing is performed on the first request based on the bandwidth limit, so that the first request can be guaranteed to be processed while the second request can be timely processed, and the second request cannot be influenced by the first request.
The above-mentioned drawbacks are the results of the inventor after practical and careful study, and therefore, the discovery process of the above-mentioned problems and the solutions proposed by the present disclosure to the above-mentioned problems should be the contribution of the inventor in the process of the present disclosure.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
To facilitate understanding of the present embodiment, first, a detailed description is given to a flow control method disclosed in the embodiments of the present disclosure, and an execution subject of the flow control method provided in the embodiments of the present disclosure is generally a terminal device with certain computing capability, for example, a smart phone, a tablet computer, a smart phone, and the like.
Referring to fig. 1, a flow chart of a flow control method provided in the embodiment of the present disclosure is shown, where the method includes steps 101 to 103, where:
And 102, determining a limited bandwidth based on a required bandwidth corresponding to the second request and a current transmission bandwidth, wherein the limited bandwidth is a maximum bandwidth for transmitting the first request.
And 103, carrying out speed limit processing on the first request according to the limited bandwidth.
The following is a detailed description of the above steps.
For step 101,
The network condition meeting the preset condition may mean that the current network condition is poor and the speed limit processing is required. When the network condition does not meet the preset condition, the current network condition is good, and speed limit processing is not needed, in this case, all the requests can be directly processed after being received.
Here, the processing of the request may refer to responding to the request, and for example, the request may be processed through a read function or a write function in a Socket corresponding to the request.
In a possible embodiment, the network condition satisfying the preset condition may include at least one of:
the network type is a preset network type; the network delay exceeds the preset time length; the network transmission speed is less than the preset transmission speed.
For example, the preset network type may be 3G, 4G, 5G, and the like.
Specifically, a network speed measurement module may be deployed on a user side executing the method provided by the present disclosure, and the network speed measurement module may monitor a current network condition in real time.
In one possible embodiment, a request list may be set in advance, and a plurality of requests stored in the request list are requests that do not need to be subjected to speed limit processing. When the network condition is detected to meet the preset condition, all the currently received requests can be intercepted, and a first request needing speed limit processing and a second request needing no speed limit processing in the received requests are determined based on a preset request list.
When the speed limit processing is carried out, the received request comprises a sending request and a receiving request, the sending request is used for sending data, the receiving request is used for receiving data, the bandwidth occupied by the sending request is the broadband in the uplink direction, the bandwidth occupied by the receiving request is the bandwidth in the downlink direction, the general network data transmission direction is full duplex transmission, namely the broadband in the uplink direction and the broadband in the downlink direction are not influenced with each other. Based on this, since the received request includes the sending request and the receiving request, the target speed limiting direction may be determined first, and then the speed limiting process may be performed on the request in the target speed limiting direction.
For example, if the current scene is a main broadcast live scene, more data is pushed stream data, and the data needs to be sent to a server, the target speed limit direction in the scene may be a sending method; if the current scene is a video scene browsed by the user, more data is video data acquired from the server, and the target speed limiting direction in the scene can be a receiving direction.
Specifically, when determining the target speed limiting direction, the following method may be exemplarily used:
method 1,
And receiving a speed limit instruction input by a user, and taking a speed limit direction corresponding to the speed limit instruction as a target speed limit direction.
Specifically, when it is detected that the network condition meets the preset condition, the speed limit prompting information, for example, the prompting information of whether the current network condition is poor and the speed limit is performed or not, can be displayed through the user side, then the speed limit direction input by the user is received, the speed limit instruction is generated, and the speed limit processing is performed based on the speed limit instruction.
Method 2,
And determining the target speed limiting direction based on the number of the requests in different directions in the plurality of currently received requests.
Specifically, a first number of requests whose transmission direction is the sending direction and a second number of requests whose sending direction is the receiving direction in the currently received plurality of requests may be determined, and then the direction with the larger number may be used as the target speed limiting direction.
For example, if the currently received plurality of requests includes 10 sending requests and 2 receiving requests, and the number of requests in the sending direction is large, the sending direction may be the target speed limiting direction.
Method 3,
And determining the target speed limiting direction based on the current service scene.
Specifically, multiple service scenes and speed limiting directions corresponding to different service scenes can be preset, then the current service scene can be determined based on the currently displayed target page, and the target speed limiting direction can be determined based on the current service scene.
After the target speed limiting direction is determined, when a first request which needs speed limiting processing and a second request which does not need speed limiting processing are determined in the plurality of received requests, the first request which needs speed limiting processing and has the transmission direction as the target speed limiting direction and the second request which does not need speed limiting processing can be determined in the plurality of received requests.
Here, the second request that does not need to perform the speed limit process may include a request that the transmission direction is not the target speed limit direction, and a request that the transmission direction is the target speed limit direction but does not need to perform the speed limit process.
In another possible implementation, the speed limit priorities of different requests may be different, and the real-time performance of part of the requests may be lower, so the speed limit priority is higher, based on which the speed limit priorities may be set for various requests in advance.
When determining that the received plurality of requests include a first request which needs speed limit processing and a second request which does not need speed limit processing, determining that the corresponding speed limit priority in the received plurality of requests meets the first request which meets the speed limit condition and has the transmission direction as the target speed limit direction; and determining a second request that the corresponding speed limit priority does not meet the speed limit condition or the transmission direction is not the target speed limit direction.
Here, the condition that the speed limit is satisfied may be, for example, that the priority of the speed limit is higher than a preset level.
With respect to step 102,
In a possible implementation manner, the current transmission bandwidth may be determined by the network speed measurement module. Because the speed limit processing can be performed only on the request in the current application program when the speed limit processing is performed, and only the bandwidth of the current application program can be detected when the bandwidth monitoring is performed, the current transmission bandwidth may refer to the bandwidth corresponding to the current application program. When only one application is currently open, the current transmission bandwidth may refer to the current bandwidth of the entire device, and when multiple applications are currently open, the current transmission bandwidth is smaller than the current bandwidth of the entire device.
In a possible implementation manner, when determining the limitation bandwidth based on the required bandwidth corresponding to the second request and the current transmission bandwidth, the limitation bandwidth may be determined based on the required bandwidth corresponding to the second request whose transmission direction is the target speed limit direction and the current transmission bandwidth.
For example, a bandwidth difference between the current transmission bandwidth and a required bandwidth corresponding to the second request may be calculated, and then the bandwidth difference may be used as a limit bandwidth.
For example, if the current transmission bandwidth is 5M and the required bandwidth corresponding to the second request is 3M, the bandwidth difference is 2M, and the limited bandwidth is also 2M.
Here, the required bandwidth corresponding to the second request may be understood as a sum of required bandwidths of all second requests whose currently received transmission direction is the speed-limiting direction, and the required bandwidth corresponding to each second request may be a minimum bandwidth that ensures normal transmission of the second request, and may be preset.
In another possible implementation manner, if the bandwidth difference between the current transmission bandwidth and the required bandwidth corresponding to the second request is small, in this case, if the rate-limiting processing is performed on the first request, a part of the first request may not be responded in time, and a program may be operated incorrectly.
Therefore, in order to ensure that the first request can be processed normally, after calculating a bandwidth difference between the current transmission bandwidth and the required bandwidth corresponding to the second request, the size between the bandwidth difference and a preset bandwidth may be determined, and when the bandwidth difference is greater than the preset bandwidth, the bandwidth difference is determined as the limited bandwidth; and when the bandwidth difference is not greater than the preset bandwidth, determining the preset bandwidth as the limited bandwidth.
The preset bandwidth is the minimum bandwidth which ensures normal transmission of the first request, and the current transmission bandwidth is the transmission bandwidth in the current target speed limiting direction.
And when the bandwidth difference is not greater than the preset bandwidth, determining the preset bandwidth as the limited bandwidth, so that the speed-limited processing of the first request can be realized and the processing speed of the second request can be increased on the premise that the first request is normally processed.
In a possible case, if the network condition satisfies the predetermined condition, the network delay exceeds the predetermined time, in this case, the delay may not be too long due to too many requests, and even if the speed limit processing is performed on the request, the network delay cannot be reduced, so that before the speed limit processing is performed on the first request, it is required to detect whether the network delay is too long due to too many requests.
Specifically, the total transmission speed of the first request that needs speed limiting processing may be determined first, and then the bandwidth limit may be determined based on the required bandwidth corresponding to the second request and the current transmission bandwidth when the total transmission speed is greater than a preset speed threshold. The preset speed threshold value can be set based on different scenes.
For step 103,
In a possible implementation manner, when performing the speed limiting processing on the first request according to the limited bandwidth, the first request may be processed sequentially through the sockets corresponding to the first requests in the order of receiving the first requests without exceeding the limited bandwidth.
When any first request is processed, if the sum of the bandwidth required by the first request and the bandwidth required by the request processed normally at present exceeds the limit bandwidth, the first request can be processed again in the next calculation period.
For example, if the bandwidth is limited to 1M, when the first request needs to be processed, if the bandwidth required by the first request 1 is 0.5M, and the bandwidth required by the first request 2 is 0.8M, if the time for receiving the first request 1 is earlier than the time for receiving the first request 2, the first request 1 may be processed first, and then the first request 2 may be processed, and when the first request 1 is processed, the remaining bandwidth is 0.5M, and the bandwidth required by the first request 2 cannot be satisfied, then the first request 2 may be re-processed in the next calculation cycle.
In a possible implementation manner, after the speed limiting processing is performed on the first request, the speed limiting effect may be detected after a period of time, and if the speed limiting effect is not obvious after the speed limiting processing is performed, the speed limiting processing may be cancelled.
Specifically, first network delay information before speed-limiting processing is performed on a first request may be determined, then, after a first preset duration after the speed-limiting processing is performed on the first request, current second network delay information may be determined, when it is determined that a delay variation condition satisfies a preset condition based on the first delay information and the second delay information, a required bandwidth corresponding to the second request is increased, a bandwidth limit is determined again, and the first request is processed according to the determined bandwidth limit.
Here, when determining whether the delay variation condition satisfies a preset condition based on the first delay information and the second delay information, a delay difference value may be determined based on the first delay information and the second delay information, and if the delay difference value is greater than a preset delay difference value, the delay variation condition may be determined to satisfy the preset condition.
Or, a delay difference value may be determined based on the first delay information and the second delay information, then a delay improvement ratio may be determined based on the delay difference value and the first delay information, and if the delay improvement ratio is greater than a preset ratio, it may be determined that the delay variation condition satisfies a preset condition.
In a possible implementation manner, when the required bandwidth corresponding to the second request is increased, the required bandwidth corresponding to the second request may be increased according to a preset increased bandwidth or according to a preset increased proportion.
For example, if the preset boost bandwidth is 0.5M, and the required bandwidth corresponding to the second request before the boost is 2M, it may be determined whether the delay variation condition meets the preset condition every first preset time, and if so, 0.5M is added on the basis of the required bandwidth corresponding to the current second request to serve as the required bandwidth corresponding to the boosted second request.
If the preset lifting bandwidth is 10%, determining whether the time delay change condition meets a preset condition every first preset time, and if so, lifting 10% on the basis of the required bandwidth corresponding to the current second request to serve as the required bandwidth corresponding to the lifted second request.
After the speed limiting processing is performed on the first request, if it is determined that the time delay change condition does not meet the preset condition based on the first time delay information and the second time delay information, it is indicated that the current speed limiting processing has no speed limiting effect, and the speed limiting processing on the first request can be cancelled.
After the speed limit processing is performed on the first request, if it is detected that the network condition does not satisfy the preset condition, that is, after it is detected that the current network condition becomes good, the speed limit processing may be stopped.
Alternatively, the speed limit processing may be stopped after the second request currently received is processed.
Or, the fool-proof process may be directly performed, that is, after the speed limit is performed for a certain period of time, in order to prevent the case that the speed limit process cannot be stopped due to the erroneous execution of the program, the speed limit process may be stopped for the first request after a second preset time period after the speed limit process is performed for the first request.
In this case, if the network status still satisfies the preset condition, step 101 to step 103 may be executed again to perform the speed limiting process again.
In practical applications, different steps in the foregoing embodiments may be executed by different modules, and the flow control method provided in the foregoing embodiments will be described below with reference to specific modules, where the modules for executing the method provided by the present disclosure may include a service logic module, a flow control module, and a network measurement and calculation module, and as shown in fig. 2, a flowchart of another flow control method provided in the embodiment of the present disclosure includes the following steps:
step 201, the service logic module obtains network status information from the network measurement and calculation module.
Step 202, after detecting that the network condition meets the preset condition, sending a speed limit instruction to the flow control module.
