Fig. 1 is a schematic flow chart of a bandwidth detection method provided by an embodiment of the present disclosure, where the embodiment of the present disclosure is applicable to detecting a bandwidth in network congestion control, the method may be performed by a bandwidth detection apparatus, and the apparatus may be implemented in a form of software and/or hardware, and optionally, implemented by an electronic device, where the electronic device may be a mobile terminal, a PC side, a server, or the like.
As shown in fig. 1, the bandwidth detection method specifically includes the following steps:
s110, responding to the current bandwidth detection stage as a bandwidth up detection stage, and acquiring a current detection result corresponding to a current detection point in the current bandwidth detection stage, wherein the bandwidth up detection stage refers to that the detection bandwidth in the current bandwidth detection stage is larger than the detection bandwidth in the last bandwidth detection stage.
The bandwidth detection is based on the estimated bandwidth determined by the bandwidth estimation algorithm in network congestion control every time. Since bandwidth estimation is performed once at intervals, bandwidth probing is also performed correspondingly once at intervals, each time a bandwidth probing process is performed corresponds to one bandwidth probing phase, that is, each bandwidth probing phase. The current bandwidth probing phase refers to the bandwidth probing phase in which the current probing is performed. The bandwidth probing phase may include a bandwidth up-probing phase, a bandwidth down-probing phase, and a bandwidth hold phase. The bandwidth up-probing stage refers to that the probing bandwidth used at the time is larger than the probing bandwidth used at the last time. The bandwidth downsampling stage refers to that the detection bandwidth used at the time is smaller than the detection bandwidth used last time. The wide hold phase refers to the detection bandwidth that is currently used being equal to the detection bandwidth that was last used. Since each probe needs to be maintained for a period of time, there may be multiple probe points (i.e., sampling points) in each bandwidth probing phase, each probe point may correspond to the same probing bandwidth. For example, referring to fig. 2, each bandwidth detection stage may include 3 detection points, such as a first bandwidth detection stage may include a 1 st detection point a followed by a 2 nd detection point and a 3 rd detection point. The second bandwidth detection phase (i.e., the phase consisting of the 4 th detection point, the 5 th detection point, and the 6 th detection point) is a bandwidth up detection phase with respect to the first bandwidth detection phase. The third bandwidth detection phase (i.e., the phase consisting of the 7 th detection point, the 8 th detection point, and the 9 th detection point) is a bandwidth down detection phase with respect to the second bandwidth detection phase. The current detection result corresponding to the current detection point may refer to a packet receiving condition sent by the current detection point based on the current detection bandwidth.
Specifically, whether the detected bandwidth used in the current bandwidth detection stage is larger than the detected bandwidth in the previous bandwidth detection stage is detected, if yes, the current bandwidth detection stage is determined to be a bandwidth up detection stage, and if not, the current bandwidth detection stage is determined to be a non-bandwidth up detection stage, such as a bandwidth down detection stage or a bandwidth holding stage. When the current bandwidth detection stage is a bandwidth up detection stage, it indicates that there may be a need to continue up detection in the current bandwidth detection stage, and at this time, a current detection result corresponding to a current detection point in the current bandwidth detection stage may be obtained. For example, the bandwidth probing process corresponding to the current probing point is: and taking the current detection bandwidth corresponding to the current detection point as the current sending code rate to send the data packet, and taking the receiving condition of the data packet as the current detection result corresponding to the current detection point.
It should be noted that, if the current bandwidth detection stage is a non-bandwidth up detection stage, it indicates that there is no up detection requirement in the current bandwidth detection stage, and at this time, bandwidth detection may be performed according to the original detection logic, for example, the current detection bandwidth is maintained for a period of time for detection, and then the next bandwidth estimation and detection are performed based on the detection result of the period of time.
S120, determining the current network state corresponding to the current detection point based on the current detection result and the historical detection result corresponding to the historical detection point.
The historical detection point may refer to a detection point before the current detection point. The historical probe points may refer to probe points within a preset historical period of time that is closest to the current time. For example, the history probe may be a history probe within the last 1 minute. The history probe may also refer to a history probe within a preset number of history bandwidth probe phases closest to the current time, which does not include the history probe within the current bandwidth probe phase, e.g., the history probe may refer to a history probe within a previous bandwidth probe phase. The current network state may be a network state in which the current probe point is located relative to a network of historical probe points. For example, the current network state may include a strong network state or a weak network state. The strong network state means that the current probe point has better network conditions than the historical probe point, that is, the current probe bandwidth used by the current probe point is smaller than the actual network bandwidth. The weak network state refers to that the network condition of the current detected network condition point is about the same as the historical detection point or the network condition of the current detection point is worse than the historical detection point, that is, the current detection bandwidth used by the current detection point is larger than the actual network bandwidth.
Specifically, the current detection result is compared with the historical detection result corresponding to the historical detection point, and whether the current network state of the current detection point is in a strong network state or a weak network state is determined based on the comparison result, so that whether the current detection point meets the condition of continuous upward detection is determined.
And S130, responding to the current network state as the strong network state, performing upward detection processing on the current detection bandwidth corresponding to the current detection point, determining the target detection bandwidth corresponding to the next detection point, and performing bandwidth detection on the next detection point based on the target detection bandwidth.
The upward sounding process may refer to a process of increasing bandwidth. The target detection bandwidth corresponding to the next detection point is larger than the current detection bandwidth corresponding to the current detection point.
Specifically, when the current network state corresponding to the current detection point is a strong network state, the current network of the current detection point is indicated to be a strong network, the condition of continuously probing is met, the current detection bandwidth can be directly subjected to probing processing to obtain a target detection bandwidth which is larger than the current detection bandwidth, the target detection bandwidth is used as a sending code rate of the next detection point to send a data packet, and the bandwidth detection of the next detection point is completed, so that the next detection point can directly probe to a larger bandwidth for detection without maintaining the current detection bandwidth unchanged. The next detection point can be used as the current detection point to execute the operation of the steps S110-S130 to continue the upward detection, so that the continuous upward detection of the detection bandwidth can be realized in the strong network state, the time spent by increasing the detection bandwidth to the reasonable range of the strong network bandwidth is shortened, and the bandwidth upward detection speed is improved.
Illustratively, "performing the upward detection process on the current detection bandwidth corresponding to the current detection point" in S130, determining the target detection bandwidth corresponding to the next detection point may include: and adding the current detection bandwidth corresponding to the current detection point with the preset upper detection interval bandwidth to obtain the target detection bandwidth corresponding to the next detection point.
The preset sounding interval bandwidth may be a preset bandwidth increased by sounding each time, that is, a bandwidth sounding step size. Specifically, bandwidth probing is performed by directly increasing the preset probing interval bandwidth on the basis of the current probing bandwidth, bandwidth estimation is not needed, and the bandwidth probing speed is further improved.
Illustratively, referring to fig. 2, each probe point in the bandwidth probing phase of the AB range is in a weak network state, so that the condition of continuous probing is not triggered, but the original bandwidth probing process is maintained. When the detection point B is detected, the system is converted into a strong network state, and the bandwidth can be directly detected (see the solid line part), and the detection bandwidth corresponding to the detection point B is not required to be maintained (see the dotted line part). Each detection point after the detection point B corresponds to a strong network state, so that continuous upward detection is performed after the detection point B until the upward detection is within a reasonable range of the strong network bandwidth, namely the detection point C. The actual network bandwidth after the detection point C is unchanged, and bandwidth estimation is not triggered, so that the detection bandwidth corresponding to the detection point C can be maintained to transmit data packets. The existing bandwidth detection mode is shown in a dotted line part, and the bandwidth is detected to be within a reasonable range of the bandwidth of the strong network only when the point D is detected. Therefore, the bandwidth detection mode of the present disclosure takes a much shorter time period (i.e., the time period corresponding to BC) than the existing bandwidth detection mode (i.e., the time period corresponding to BD), so that the bandwidth detection mode of the present disclosure can greatly shorten the bandwidth detection time and increase the bandwidth detection speed.
According to the technical scheme, the current detection result corresponding to the current detection point in the current bandwidth detection stage is obtained by responding to the current bandwidth detection stage as the bandwidth up detection stage, the current network state corresponding to the current detection point is determined based on the current detection result and the history detection result corresponding to the history detection point, the current detection bandwidth corresponding to the current detection point is directly subjected to up detection processing in response to the current network state being a strong network state, the target detection bandwidth corresponding to the next detection point is determined, and the next detection point is subjected to bandwidth detection based on the target detection bandwidth, so that the next detection point is subjected to width up detection directly without maintaining the current detection bandwidth for a period of time, continuous up detection of the detection bandwidth is realized in the bandwidth up detection stage, the bandwidth up detection speed is improved, and further the audio and video experience of real-time communication is improved.
Based on the technical scheme, the method further comprises the following steps: determining a weak network state duration in a current bandwidth detection stage in response to the current network state being a weak network state; and comparing the weak network state duration with a preset duration, and detecting the bandwidth of the next detection point based on the comparison result.
The weak network state duration may refer to a duration in which the detection bandwidth in the current bandwidth detection phase is continuously maintained. The preset duration may refer to a preset maximum duration for which the probe bandwidth remains unchanged.
Specifically, in the current bandwidth detection stage, that is, in the bandwidth probing stage, if the current network state corresponding to the current detection point is detected to be the weak network state, it indicates that the condition of continuing probing is not met currently, and at this time, the probing bandwidth can be maintained for a period of time. By comparing the duration of the weak network state in the current bandwidth detection phase with the preset duration, whether to continue to maintain the detection bandwidth unchanged or end the current bandwidth detection phase can be determined, so that the next bandwidth detection phase can be entered based on the re-estimated bandwidth, and the original bandwidth detection logic can be compatible on the basis of realizing continuous bandwidth up-detection.
Illustratively, performing bandwidth detection on the next detection point based on the comparison result may include: if the duration of the weak network state is smaller than the preset duration, taking the current detection bandwidth corresponding to the current detection point as a target detection bandwidth, and carrying out bandwidth detection on the next detection point; if the duration of the weak network state is longer than or equal to the preset duration, the current bandwidth detection stage is determined to be ended.
Specifically, when the duration of the weak network state is smaller than the preset duration, it indicates that the current detection bandwidth can be continuously maintained for detection, and at this time, the current detection bandwidth corresponding to the current detection point is used as the target detection bandwidth, that is, the sending code rate of the next detection point is used for sending a data packet, so that the sending code rate is maintained unchanged for detecting the bandwidth of the next detection point. The operation of performing the above steps S110 to S130 may be performed in a manner that the next detection point is regarded as the current detection point, and the detection may be looped until the end of the current bandwidth detection phase, if the upward detection process is possible at the next detection point. When the duration of the weak network state is longer than or equal to the preset duration, the current detection bandwidth is not required to be maintained for detection, and the end of the current bandwidth detection stage can be determined at the moment, so that the detection operation in the current bandwidth detection stage is ended, the next bandwidth detection stage is started based on the re-estimated bandwidth, and the original bandwidth detection logic can be compatible on the basis of realizing continuous upper detection of the bandwidth.
Fig. 3 is a flowchart of another bandwidth detection method provided by an embodiment of the present disclosure, where a process of determining a current network state corresponding to a current detection point is described in detail based on the above embodiment of the present disclosure. Wherein the same or corresponding terms as those of the above-described embodiments are not explained in detail herein.
As shown in fig. 3, the bandwidth detection method specifically includes the following steps:
s310, responding to the current bandwidth detection stage as a bandwidth up detection stage, and acquiring a current detection result corresponding to a current detection point in the current bandwidth detection stage.
S320, determining the transmittance of the current code rate corresponding to the current detection point based on the current sending code rate and the current receiving code rate in the current detection result.
The current code rate transmittance can be used for representing the network strength corresponding to the current detection point. The larger the current code rate transmittance is, the stronger the network corresponding to the current detection point is, that is, the larger the current actual network bandwidth is than the current detection bandwidth.
Specifically, dividing the current receiving code rate corresponding to the current detection point by the current sending code rate to obtain the current code rate transmittance corresponding to the current detection point.
S330, determining the reference code rate transmittance corresponding to the historical detection point based on the historical sending code rate and the historical receiving code rate in the historical detection result corresponding to the historical detection point.
Wherein the number of history detection points is a plurality. The reference code rate transmittance can be used for representing the network strength of the whole historical detection point. The larger the reference code rate transmittance is, the stronger the network of the whole historical detection point is, that is, the larger the historical actual network bandwidth is than the historical detection bandwidth.
Specifically, statistical processing is performed based on the historical sending code rate and the historical receiving code rate corresponding to all the historical detection points, and the reference code rate transmittance corresponding to all the historical detection points is determined.
Illustratively, S330 may include: determining the transmission rate of the historical code rate corresponding to each historical detection point based on the historical transmission rate and the historical reception rate in the historical detection result corresponding to each historical detection point; and carrying out average processing on all the historical code rate transmittance, and determining the reference code rate transmittance corresponding to the historical detection point.
Specifically, dividing the historical receiving code rate corresponding to each historical detection point by the corresponding historical sending code rate to obtain the historical code rate transmittance corresponding to each historical detection point. And carrying out average processing on all the historical code rate transmittance, and determining the obtained average historical code rate transmittance as the reference code rate transmittance corresponding to the historical detection point.
S340, determining the current network state corresponding to the current detection point based on the current code rate transmittance and the reference code rate transmittance.
Specifically, the current code rate transmittance is compared with the reference code rate transmittance, so that the current network state corresponding to the current detection point can be accurately determined, and further the accuracy of continuous bandwidth probing is ensured. For example, determining a ratio between the transmittance of the current code rate and the transmittance of the reference code rate, comparing the ratio with a preset ratio, if the ratio is greater than or equal to the preset ratio, determining that the current network state corresponding to the current detection point is a strong network state, otherwise, determining that the current network state is a weak network state. The preset ratio may be a preset ratio threshold that allows the upward detection to be continued, where the ratio threshold is a value greater than 1.
Illustratively, S340 may include: determining a ratio between the transmittance of the current code rate and the transmittance of the reference code rate, and comparing the ratio with a preset ratio to obtain a first comparison result; comparing the reference code rate transmittance with a preset transmittance to obtain a second comparison result; and determining the current network state corresponding to the current detection point based on the first comparison result and the second comparison result.
The preset transmittance may be a preset maximum historical transmittance that allows the continuous upward probing. Specifically, by integrating the first comparison result and the second comparison result, the current network state corresponding to the current detection point can be more accurately determined, and the accuracy of continuous bandwidth detection is further improved.
Illustratively, determining the current network state corresponding to the current probe point based on the first comparison result and the second comparison result may include: if the ratio is greater than or equal to the preset ratio and the reference code rate transmittance is greater than or equal to the preset transmittance, determining that the current network state corresponding to the current detection point is a strong network state; if the ratio is smaller than the preset ratio or the reference code rate transmittance is smaller than the preset transmittance, determining that the current network state corresponding to the current detection point is a weak network state.
Specifically, if the reference code rate transmittance is greater than or equal to the preset transmittance, it indicates that the network in the recent historical time period may be a strong network, and the current detection point is accurately detected, and when the ratio corresponding to the current detection point is detected to be greater than or equal to the preset ratio, it indicates that enough space exists currently for continuous detection, and the current network state corresponding to the current detection point is determined to be a strong network state, so that the detection can be continued on the basis of the current detection point.
If the ratio corresponding to the current detection point is smaller than the preset ratio, the fact that enough space does not exist at present for continuous upward detection is indicated, and at the moment, the current network state can be directly determined to be the weak network state. Or if the reference code rate transmittance is smaller than the preset transmittance, the network in the latest historical time period is indicated to be a weak network, the current detection point is inaccurately detected, and the current network state can be directly determined to be a weak network state at the moment, so that continuous bandwidth detection is avoided, and the accuracy of bandwidth detection is ensured.
And S350, responding to the current network state as the strong network state, performing upward detection processing on the current detection bandwidth corresponding to the current detection point, determining the target detection bandwidth corresponding to the next detection point, and performing bandwidth detection on the next detection point based on the target detection bandwidth.
According to the technical scheme, the current code rate transmittance corresponding to the current detection point is determined based on the current sending code rate and the current receiving code rate in the current detection result, the reference code rate transmittance corresponding to the historical detection point is determined based on the historical sending code rate and the historical receiving code rate in the historical detection result corresponding to the historical detection point, and the current network state corresponding to the current detection point can be accurately determined based on the current code rate transmittance and the reference code rate transmittance, so that the accuracy of continuous bandwidth probing is guaranteed.
