Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a method for controlling a traffic transmission speed according to an embodiment of the present application. As shown in fig. 1, in the present embodiment, the method includes:
s11: and determining the current flow reference speed based on the flow transmission speed of the client and the server for executing the tasks according to the historical set time length and the flow transmission speed of the client and the server for executing the tasks currently.
Referring to fig. 2, fig. 2 is a flowchart illustrating an embodiment of step S11 in fig. 1. As shown in fig. 2, in the present embodiment, the step of determining the current traffic reference speed based on the traffic transmission speed of the client and the server for performing the task in the historical set time length and the traffic transmission speed of the client and the server for currently performing the task specifically includes:
s21: and determining an initial flow reference speed based on the flow transmission speed of the tasks executed by the historical set time length of the client and the server.
In this embodiment, the traffic reference speed refers to the maximum bandwidth that can be reached by the client bandwidth and the acceleration server acting together, i.e. the estimated upper bandwidth limit.
In the present embodiment, the traffic transfer rate is an actual traffic transfer rate provided by the client and the server together.
The traffic transmission speed of the historical set time period execution task is an average value of traffic transmission speeds received in a time (previous time) closest to the current time, and is a value closest to the actual traffic transmission speed.
The time may be 3s, 5s or other time, which is not limited in the present application.
In this embodiment, the initial traffic reference speed is calculated according to the traffic transmission speed received in real time at the previous time.
S22: the initial flow reference speed is compared to a flow reference speed that precedes the initial flow reference speed.
In this embodiment, since the flow reference speed is dynamically changed, before the initial flow reference speed is adjusted, the change trend of the flow reference speed at the previous several moments needs to be obtained, the state of the initial flow reference speed is determined according to the change trend, and finally, the initial flow reference speed is adjusted based on the state of the initial flow reference speed to obtain the current flow reference speed.
S23: and adjusting the initial flow reference speed by using the comparison result and the flow transmission speed of the currently executed task, and determining the adjusted speed as the current flow reference speed.
Referring to fig. 3, fig. 3 is a flowchart illustrating an embodiment of step S23 in fig. 2. As shown in fig. 3, in the present embodiment, the step of adjusting the initial traffic reference speed by using the comparison result and the traffic transmission speed of the currently executed task, and determining the adjusted speed as the current traffic reference speed specifically includes:
s31: determining the state of the initial flow reference speed by using the comparison result; wherein the states include a steady state and an observed state.
In this embodiment, the steady state means that the change in the flow rate reference speed is very slight over a period of time or it is directly considered that it does not change; the observation state refers to a state in which the flow rate reference speed is largely changed over a period of time.
Specifically, referring to fig. 4, fig. 4 is a flowchart illustrating an embodiment of step S31 in fig. 3. As shown in fig. 4, in the present embodiment, the step of determining the state of the initial flow rate reference speed using the comparison result specifically includes:
s41: and judging whether the quantity of the flow reference speeds before the initial flow reference speed reaches a preset quantity or not.
In this embodiment, the premise of determining whether the number of the flow reference speeds before the initial flow reference speed reaches the preset number is that, between the preset number of flow reference speeds, a difference between two consecutive flow reference speeds is smaller than a preset value, and in response to that, a difference between the initial flow reference speed and the flow reference speed immediately before the initial flow reference speed is smaller than a preset value. And if the difference value between the initial flow reference speed and the flow reference speed immediately before the initial flow reference speed is not smaller than the preset value, abandoning the flow reference speed before the initial flow reference speed, and determining the initial flow reference speed as the first flow reference speed.
Specifically, since the change of the flow reference speed in the steady state is very slight, the difference between the flow reference speeds at the previous and subsequent times in the steady state is small and usually lower than the preset value, and if the difference between the flow reference speed in response to the initial flow reference speed and the flow reference speed at the previous time is not smaller than the preset value, indicating that the change of the flow reference speed in the time is large, the initial flow reference speed is directly determined to be in the observation state.
In the present embodiment, the preset value is 5%.
In other embodiments, the preset value may be 3%, 4% or other values, which is not limited in this application.
S42: and if the number does not reach the preset number, determining the state as the observation state.
In this embodiment, determining the state of the initial flow reference speed requires observing the change trend of the flow reference speed over a period of time, so that there is a certain requirement on the length of the observation queue of the flow reference speed. If the number does not reach the preset number, the further observation is still needed, and at the moment, the initial flow reference speed is directly judged to be in an observation state.
In the present embodiment, the predetermined number is 5.
In other embodiments, the preset number may also be 8, 10 or other numbers, which is not limited in this application.
S43: and if the quantity reaches the preset quantity, determining that the state is a stable state in response to that the difference value between the initial flow reference speed and the flow reference speed at the previous moment is less than the preset value, and the difference value between the average value of the initial flow reference speed and the first flow reference speed in the preset quantity is less than the preset value.
In this embodiment, it is determined that the initial flow reference speed is in a stable state and two conditions need to be satisfied, one of which is whether the number of flow reference speeds before the initial flow reference speed reaches a preset number; the difference between the average value of the initial flow reference speed and the first flow reference speed in the preset number is smaller than the preset value, and the initial flow reference speed can be judged to be in a stable state only if the two conditions are met simultaneously.
Wherein, the first condition shows that the difference value between two continuous flow reference speeds in the observation queue is less than the preset value, and shows that the change value of the flow reference speed is not large; the second condition is that the overall variation trend of the plurality of flow reference speeds in the preset number is smooth.
Specifically, please refer to fig. 6, fig. 6 is a specific diagram illustrating a variation trend of the flow reference speed with a predetermined number according to the present application. As shown in fig. 6, in the observation queue, the flow reference speed is in a state of rising and falling, and the change trend is generally smooth, so that the difference between the 5 th flow reference speed (i.e. the initial flow reference speed) and the 1 st flow reference speed is less than 5%. And when the difference between the 5 th flow reference speed and the 1 st flow reference speed is less than 5%, the difference between the average value of the two and the 1 st flow reference speed is also necessarily less than 5%, and the condition is met, and the initial flow reference speed is judged to be in a stable state.
S44: and if the quantity reaches the preset quantity, determining that the state is the observation state in response to that the difference value between the initial flow reference speed and the flow reference speed at the previous moment is not less than the preset value or/and the difference value between the initial flow reference speed and the first flow reference speed in the preset quantity is not less than the preset value and the average value between the initial flow reference speed and the first flow reference speed in the preset quantity.
If the difference value between the initial flow reference speed and the flow reference speed immediately before the initial flow reference speed is not smaller than the preset value, the first condition is not met; and if the difference value between the average value of the initial flow reference speed and the first flow reference speed in the preset number is not less than the preset value, the second condition is not met, and if one of the two conditions is not met, the initial flow reference speed is judged to be in an observation state.
Since the difference is an absolute value and cannot represent the direction of change, the difference between two consecutive flow reference speeds is less than a preset value, and does not represent the average value of the initial flow reference speed at the end of the queue and the first flow reference speed in the preset number, and the difference between the initial flow reference speed at the end of the queue and the first flow reference speed in the preset number is less than the preset value. If all traffic reference speeds in the queue are either rising or falling, then condition two is likely not satisfied.
Specifically, please refer to fig. 7, fig. 7 is another specific diagram illustrating a variation trend of the reference speed of the preset amount of the flow rate. As shown in fig. 7, in the observation queue, the flow reference speed is in a state of continuously decreasing, although the difference between two consecutive flow reference speeds is less than 5%, the difference between the 5 th flow reference speed (i.e. the initial flow reference speed) and the 1 st flow reference speed is greater than 5%, and whether the difference between the average value of the two and the 1 st flow reference speed is less than 5% depends on the magnitude of each decrease, if the magnitude of each decrease is small enough, for example, 1% decrease each time, if the 1 st flow reference speed is a, the 5 th flow reference speed is 0.96a, the average value of the two is 0.98a, and the difference between the two and the 1 st flow reference speed is 2%, less than 5%, the condition can still be satisfied; if the reduction amplitude is slightly large each time, for example, each time is reduced by 4.5%, if the 1 st flow reference speed is a, the 5 th flow reference speed is 0.85a, the average value of the two is 0.925a, and the difference value from the 1 st flow reference speed is 7.5%, which is greater than 5%, the condition cannot be met, and at this time, the initial flow reference speed is determined to be in the observation state.
S32: and determining the adjustment mode of the flow reference speed at the next moment based on the state of the initial flow reference speed.
In the embodiment, after the state of the initial flow reference speed is determined to be a stable state, the initial flow reference speed is adjusted according to the adjustment mode of the stable state; and after the state of the initial flow reference speed is determined to be an observation state, adjusting the initial flow reference speed according to an adjustment mode of the observation state.
S33: and adjusting the initial flow reference speed by using an adjusting mode to obtain the current flow reference speed.
Referring to fig. 5, fig. 5 is a flowchart illustrating an embodiment of step S33 in fig. 3. As shown in fig. 5, in the present embodiment, the step of adjusting the initial flow rate reference speed by using an adjustment method to obtain the current flow rate reference speed specifically includes:
s51: and acquiring a difference value between the flow transmission speed of the currently executed task and the initial flow reference speed.
S52: if the state is the observation state, in response to the fact that the flow transmission speed of the currently executed task is larger than the initial flow reference speed, the initial flow reference speed is increased by a first proportion of a difference value, and the increased flow reference speed is determined as the current flow reference speed; in response to the fact that the flow transmission speed of the currently executed task is smaller than the initial flow reference speed, the initial flow reference speed is decreased by a second proportion of the difference value, and the decreased flow reference speed is determined as the current flow reference speed; wherein the first ratio is greater than the second ratio.
In this embodiment, if the traffic transmission speed in response to the currently executed task is greater than the initial traffic reference speed, it indicates that the estimated upper limit of the bandwidth is lower than the actual traffic transmission speed, and in order to approach the actual traffic transmission speed as soon as possible, and the speed of the increase needs to be faster, the initial traffic reference speed needs to be increased by a larger proportion, so that the current traffic reference speed approaches the actual traffic transmission speed as close as possible; if the traffic transmission speed in response to the currently executed task is lower than the initial traffic reference speed, it indicates that the estimated upper bandwidth limit is higher than the actual traffic transmission speed.
In the present embodiment, the first ratio is 50% and the second ratio is 10%.
In other embodiments, the first ratio and the second ratio may be other values, and it is only necessary that the first ratio is greater than the second ratio, which is not limited in the present application.
S53: if the state is a stable state, in response to the fact that the flow transmission speed of the currently executed task is larger than the initial flow reference speed, the initial flow reference speed is increased by a third proportion of the difference value, and the increased flow reference speed is determined as the current flow reference speed; in response to the fact that the flow transmission speed of the currently executed task is smaller than the initial flow reference speed, the initial flow reference speed is decreased by a third proportion of the difference value, and the decreased flow reference speed is determined as the current flow reference speed; wherein the third ratio is less than or equal to the second ratio.
In the present embodiment, the third ratio is 10% or less than 10%.
Further, after entering the stable state, if it is observed that the traffic transmission speed in the short period is greater than 120% of the traffic reference speed at the corresponding moment, and the average value of the traffic transmission speeds in the long period is also greater than 110% of the average value of the traffic reference speeds, it is determined that the stable state is broken due to the fact that the actual traffic transmission speed is increased too fast, and the stable state is reentered into the observation state.
Here, the short period refers to 5s, and the long period refers to 30 seconds.
In this embodiment, it is determined that the steady state is exited only if the flow rate transmission rate is greater than the flow rate reference rate by a value exceeding a certain ratio in both the short period and the long period.
Further, after entering the stable state, if it is observed that the flow transmission speed in the short period is less than 80% of the flow reference speed at the corresponding moment, and the average value of the flow transmission speeds in the long period is also less than 90% of the average value of the flow reference speeds, it is determined that the stable state is broken due to the fact that the actual flow transmission speed is decreased too fast, and the stable state is reentered into the observation state.
In this embodiment, after the steady state is destroyed, the speed control of the acceleration server is directly cancelled, and after the flow reference speed enters the steady state, the flow transmission speed of the server is controlled by taking a speed control measure.
In other embodiments, if the steady state is destroyed by a speed increase, the trend is to reduce the server speed, so the increase is mainly due to the potential release of the user shared connection, the traffic transmission speed of the server can be limited at a slow speed, and the traffic transmission speed of the server is further limited after the actual traffic transmission speed is observed to be still increased.
S12: and matching the current flow reference speed with a plurality of preset speed intervals, and determining the speed interval to which the current flow reference speed belongs.
Specifically, please refer to fig. 8, fig. 8 is a specific diagram illustrating a plurality of speed intervals according to the present application. As shown in fig. 8, in response to the current flow rate reference speed being greater than the first preset speed v1, dividing the current flow rate reference speed into a first speed section a; in response to the current flow reference speed being less than the first preset speed v1 but greater than the second preset speed v2, dividing the current flow reference speed into a second speed interval B; in response to the current flow reference speed being less than the second preset speed v2 but greater than the third preset speed v3, dividing the current flow reference speed into a third speed interval C; and dividing the current flow reference speed into a fourth speed interval D in response to the current flow reference speed being less than the third preset speed v 3.
The first preset speed v1 is greater than the second preset speed v2, and the second preset speed v2 is greater than the third preset speed v 3.
In the present embodiment, the first preset speed v1 is 95% of the actual transport flow rate, the second preset speed v2 is 88% of the actual transport flow rate, and the third preset speed v3 is 80% of the actual transport flow rate.
S13: and adjusting the traffic transmission speed of the server at the next moment according to the speed adjustment mode corresponding to the speed interval.
In response to the speed interval being the first speed interval A, reducing the traffic transmission speed of the server by a first set proportion; responding to the second speed interval B of the speed interval, and maintaining the traffic transmission speed of the server; responding to the speed interval as a third speed interval C, and increasing the flow transmission speed of the server by a second set proportion; and in response to the speed interval being the fourth speed interval, canceling the limitation on the traffic transmission speed of the server.
Wherein the first set proportion is 1%, and the second set proportion is 1%.
In other embodiments, the first set ratio and the second set ratio may be other values, which is not limited in the present application.
In the embodiment, when the flow reference speed is higher, the connection from some clients to the server is closed, and the upper limit of the connection is locked to prevent the generation of new connection; and when the traffic reference speed is lower, the connection from the client to the server is released, and the traffic transmission speed of the server is increased by creating a new connection.
In this embodiment, if the speed interval to which the client belongs is the first speed interval a, it indicates that the traffic reference speed is greater than 95% of the actual transmission traffic speed, and in this speed interval, the bandwidth upper limit provided by the client and the server together is very large, so that the user experience can be ensured.
In the present embodiment, the traffic transmission speed of the server is reduced by the first set ratio by reducing the number of connections from the client to the server.
Specifically, all connections from the client to the server are arranged according to the traffic transmission speed of the current moment of the connection, and the connections are sequentially closed according to the arrangement sequence from low to high until the traffic transmission speed of the server is reduced according to a first set proportion.
For example, the traffic transmission speed of the server is reduced by 1%, if the current traffic transmission speed of the server is b, the traffic transmission speed of the server at the next moment is 0.99b, and the difference quota is 0.01b, 0.01b is less than or equal to the traffic transmission speed of the server connection 1 to be closed + the traffic transmission speed of the server connection 2 to be closed + … + the traffic transmission speed of the server connection n to be closed; wherein the traffic transmission speed of the server connection to be closed 1 < the traffic transmission speed of the server connection to be closed 2 < … < the traffic transmission speed of the server connection to be closed n.
If the number of currently controlled server connections is too large (>50), some extra low speed connections are additionally closed from low to high (speed <10KB/s), and the upper limit of the number of closed connections is one twelfth of the number of controlled server connections.
In this embodiment, if the speed interval is the second speed interval B, it indicates that the traffic reference speed is 88% to 95% of the actual transmission traffic speed, and in this speed interval, the upper limit of the bandwidth provided by the client and the server together is large, so that the user experience can be ensured.
In this embodiment, if the speed interval is the third speed interval C, it indicates that the traffic reference speed is 80% to 88% of the actual transmission traffic speed, and in this speed interval, the upper limit of the bandwidth provided by the client and the server together is small, and the user experience cannot be guaranteed.
In this embodiment, the traffic transmission speed of the server is increased by the second set ratio by increasing the number of connections from the client to the server.
Specifically, a difference value between the target speed and the flow transmission speed of the current server is obtained, if the difference value is greater than 3 times of the connection equalizing speed of the server, 1 connection is added, and 1 connection limit is added every time when the remaining difference value is greater than 500k until the maximum connection number is full.
The server connection average speed refers to the ratio of the total traffic transmission speed provided by the server to the total connection number. For example, if there are only 5 connections from the client to the server in total, and the total traffic transmission speed of the server is c, then the server connection averaging speed is c/5.
In this embodiment, if the speed interval to which the client belongs is the fourth speed interval, it indicates that the traffic reference speed is less than 80% of the actual transmission traffic speed, and in this speed interval, the upper limit of the bandwidth provided by the client and the server together is very small, and the user experience cannot be guaranteed at all.
In other embodiments, the controlled connections may be collected based on a tcp (Transmission Control Protocol) reception Control method, so as to integrally Control the reception behavior of the client, so that the traffic Transmission speed of the server approaches the target value. The receiving action of the overall control client means that the server sends all data, but the control client receives only one part of the data, and the rest data is stored in the protocol station.
In another embodiment, the quota may be set autonomously, and the length of the data request in the connection may be controlled to make the traffic transmission speed of the server approach the target value. The control of the length of the data request in the connection means that the client requests a part of data from the server based on the quota, and the server only sends corresponding data according to the request.
Further, if the actual transmission traffic speed of the client is mainly provided by the server, for example, 80% of the actual transmission traffic speed is provided by the traffic transmission speed of the server, it can be determined that there are few traffic resources except for the server connection, and the client has substantially no speed-up potential, then the logic of the control method of the present application is not executed.
Further, a bottom-keeping speed of the flow reference speed is set, and if the actual flow transmission speed is lower than the bottom-keeping speed or lower than the bottom-keeping speed of a set proportion, the fact that the client side basically has no speed-raising potential is judged, the logic of the control method is not executed.
For example, the present application sets the guaranteed base rate of the traffic reference rate to 800KB/s, and if the actual traffic transmission rate is below 800KB/s or below 720KB/s (below 90% guaranteed base rate), the logic of the control method of the present application does not execute.
