Detailed Description

In order to make the technical solutions disclosed in the present application better understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

Some terms appearing herein are explained below:

1. and (3) a congestion control algorithm: within a certain period of time, the demand for resources (link capacity, cache and processors in the switching node, etc.) in the network is greater than the current available resources, which may cause congestion, and the congestion control algorithm is an algorithm that prevents too much data from being injected into the network, which may cause congestion so that the router or link is not overloaded.

2. Historical performance detection values: for measuring data transmission performance. The performance index related to the data transmission performance may be an average bandwidth, a bandwidth median, an average throughput, a median of throughputs, and the like.

3. Bayesian optimization: a Bayesian Optimization (BO) model is used for machine learning parameter adjustment in artificial intelligence, and the main idea is that an optimized business objective function (generalized function) is given, only input and output need to be specified, and the internal structure and mathematical properties do not need to be known), and posterior distribution of the business objective function is updated by continuously adding historical transmission performance difference information until the posterior distribution is basically fit with real distribution. In short, the information of the last parameter is taken into consideration, so that the current parameter can be better adjusted. The Bayesian optimization model can consider the previous parameter information, continuously updates prior distribution, and has less parameter iteration times and high speed.

4. Gaussian process: gaussian Process (GP), a type of stochastic Process in probability theory and mathematical statistics, is a combination of a series of random variables (random variables) that obey a normal distribution within an index set. To use bayesian optimization, we need an efficient way to model the distribution of the objective function. This is much simpler than modeling the true number directly, since we need only model f (x) with a distribution of confidence to find the optimal solution. If x contains a continuous hyperparameter, then there will be an infinite number of x's to model f (x), i.e., construct a distribution to the objective function. For this problem, the gaussian process actually generates a multidimensional gaussian distribution that is flexible enough to model any objective function.

5. The terminal equipment: also known as User Equipment (UE), Mobile Station (MS), Mobile Terminal (MT), etc., is a device that provides voice and/or data connectivity to a User, for example, a handheld device with a wireless connection function, a vehicle-mounted device, etc. Currently, some examples of terminal devices are: mobile phone (Mobile phone), tablet computer, notebook computer, palm computer, Mobile Internet Device (MID).

6. A client: the Application program may refer to a software Application (APP) or a terminal device. The system is provided with a visual display interface and can interact with a user; is corresponding to the server, and provides local service for the client. For software applications, except some applications that are only run locally, the software applications are generally installed on a common client terminal and need to be run in cooperation with a server terminal. After the internet has developed, more common applications include e-mail clients for e-mail receiving and sending, and instant messaging clients. For such applications, a corresponding server and a corresponding service program are required in the network to provide corresponding services, such as database services, configuration parameter services, and the like, so that a specific communication connection needs to be established between the client terminal and the server terminal to ensure the normal operation of the application program.

7. A server: the cloud server may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server providing basic cloud computing services such as cloud service, a cloud database, cloud computing, a cloud function, cloud storage, Network service, cloud communication, middleware service, domain name service, security service, Content Delivery Network (CDN), big data and an artificial intelligence platform.

After introducing the design concept of the embodiment of the present application, the following describes the above two implementations with reference to application scenarios, respectively, and it should be noted that the application scenarios described below are only used for describing the embodiment of the present application and are not limited. In a specific implementation process, the technical scheme provided by the embodiment of the application can be flexibly applied according to actual needs.

In practical application, the objective function may be set according to a practical application scenario, which is not limited herein.

The server 12 and the client may be connected for data communication via a wireless network or a wired network.

In the following, in conjunction with the above-described optional application scenarios, the transmission control method provided in the exemplary embodiment of the present application is described with reference to fig. 2 to fig. 4. It should be noted that the above application scenarios are only presented to facilitate understanding of the spirit and principles of the present application, and the embodiments of the present application are not limited in this respect. Rather, embodiments of the present application may be applied to any scenario where applicable.

As shown in fig. 2, a schematic flow chart of a transmission control method provided in the embodiment of the present application is shown, where the method may include the following steps:

step S201, when a server triggers a transmission performance adjustment request, acquiring historical transmission performance difference information between a historical optimized transmission connection and a historical benchmark transmission connection in a historical preset period;

the historical optimized transmission connection is a historical transmission connection adopting historical optimized congestion control parameters, and the historical benchmark transmission connection is a historical transmission connection adopting preset benchmark congestion control parameters.

An optional implementation manner is that, in the embodiment of the present application, the server may trigger the transmission performance adjustment request according to the following manner:

acquiring a first historical performance detection value corresponding to a historical optimized transmission connection in a historical preset period and a second historical performance detection value corresponding to a historical benchmark transmission connection; if the first historical performance detection value is less than the second historical performance detection value, a transmission performance adjustment request is triggered.

The first and second historical performance detection values may each be used to measure data transmission performance, for example, the first and second historical performance detection values may be detection values corresponding to an average bandwidth, a median bandwidth, an average throughput, a median throughput, and the like.

It should be noted that, in the embodiment of the present application, the server triggers the transmission performance adjustment request; the server judges whether the performance indexes of the historical optimized transmission connection and the historical benchmark transmission connection established in the historical preset period meet preset conditions or not, wherein the preset conditions are transmission performance corresponding to the historical optimized transmission connection and are superior to the transmission performance corresponding to the historical benchmark transmission connection; if the server determines that the performance indexes of the historical optimized transmission connection and the historical benchmark transmission connection established in the historical preset period do not accord with the preset conditions, the transmission performance corresponding to the historical optimized transmission connection is poorer than the transmission performance corresponding to the historical benchmark transmission connection, namely the first historical performance detection value is smaller than the second historical performance detection value, the fact that the historical optimized congestion control parameters adopted by the historical optimized transmission connection need to be adjusted is indicated, and a transmission performance adjustment request is triggered.

For example, the history preset period is 2T to 3T (e.g., T =40 minutes), and in the 2T to 3T period, the history optimized transmission connection established between the server and the client is, for example, the history optimized transmission connection 1, and the history optimized transmission connection 1 adopts the history optimized congestion control parameter a₁(ii) a The historical reference transmission connection established between the server and the client takes the historical reference transmission connection 2 as an example, and the historical reference transmission connection 2 adopts a preset reference congestion control parameter B; history optimized transport connectionReceiving that 1 corresponding first historical performance detection value is U₁（A₁) The second historical performance detection value corresponding to the historical reference transmission connection 2 is U₂(B) (ii) a If the server determines U₁（A₁) Less than U₂(B) Then a transmission performance adjustment request is triggered.

It should be noted that, if at least two historical optimized transmission connections or at least two historical standard transmission connections are established within a historical preset period, a first historical performance detection value corresponding to the historical optimized transmission connection and a second historical performance detection value corresponding to the historical standard transmission connection are obtained, where the first historical performance detection value or the second historical performance detection value is an average value of the first historical performance detection values corresponding to the at least two historical optimized transmission connections or an average value of the second historical performance detection values corresponding to the at least two historical standard transmission connections.

The average value is used for representing the average transmission performance corresponding to each historical optimized transmission connection adopting the historical optimized congestion control parameters, or is used for representing the average transmission performance corresponding to each historical benchmark transmission connection adopting the preset benchmark congestion control parameters.

It should be noted that, in the embodiment of the present application, the server triggers the transmission performance adjustment request; the server judges whether the performance indexes of the historical optimized transmission connection and the historical benchmark transmission connection established in the historical period meet preset conditions, wherein the preset conditions are average transmission performance corresponding to each historical optimized transmission connection in the historical optimized transmission connection and are superior to the average transmission performance corresponding to each historical benchmark transmission connection in the historical benchmark transmission connection; if the server determines that the performance indexes of the historical optimized transmission connection and the historical benchmark transmission connection established in the historical preset period do not meet the preset conditions, the average transmission performance corresponding to each historical optimized transmission connection in the historical optimized transmission connection is poorer than the average transmission performance corresponding to each historical benchmark transmission connection in the historical benchmark transmission connection, which indicates that the historical optimized congestion control parameters adopted by the historical optimized transmission connection need to be adjusted, and then a transmission performance adjustment request is triggered.

For example, the historical preset period is 2T-3T, in the 2T-3T period, the historical optimized transmission connection established between the server and the client is, for example, the historical optimized transmission connection 1, the historical optimized transmission connection 2, and the historical optimized transmission connection 3, and the historical optimized transmission connection 1, the historical optimized transmission connection 2, and the historical optimized transmission connection 3 adopt the historical optimized congestion control parameter a₂(ii) a The historical reference transmission connection established between the server and the client is exemplified by a historical reference transmission connection 4 and a historical reference transmission connection 5, and the historical reference transmission connection 4 and the historical reference transmission connection 5 adopt a preset reference congestion control parameter B; the historical performance detection value corresponding to the historical optimized transmission connection 1 is U₁（A₂) The historical performance detection value corresponding to the historical optimized transmission connection 2 is U₂（A₂) The historical performance detection value corresponding to the historical optimized transmission connection 3 is U₃（A₂) The historical performance detection value corresponding to the historical transmission connection 4 is U₄(B) The historical performance detection value corresponding to the historical transmission connection 5 is U₅(B) (ii) a Server determination U₁（A₂）、U₂（A₂）、U₃（A₂) Has an average value of X₁，U₄（B）、U₅(B) Has an average value of X₂If the server determines X₁Less than X₂Then a transmission performance adjustment request is triggered.

It should be noted that, if a history preset period corresponds to multiple history preset periods, the server obtains a first history performance detection value corresponding to a history optimized transmission connection in a previous history preset period of the current preset period and a second history performance detection value corresponding to a history reference transmission connection, and if the first history performance detection value is smaller than the second history performance detection value, a transmission performance adjustment request is triggered; the time periods corresponding to the plurality of historical preset periods are time periods between the ending time of the historical preset period which triggers the transmission performance adjustment request last time and the starting time of the current preset period. For example, the historical preset period of the last trigger transmission performance adjustment request is 0-T, and the end time corresponds to the time point T₁Current presetThe period is 3T-4T, and the starting time corresponds to the time point T₂If the time period corresponding to the two historical preset periods T-2T and 2T-3T is T₁~t₂。

After triggering the performance adjustment request, the server in the embodiment of the application needs to acquire historical transmission performance difference information between the historical optimized transmission connection and the historical benchmark transmission connection in a historical preset period.

In some embodiments, the server according to the embodiments of the present application may obtain historical transmission performance difference information between the historical optimized transmission connection and the historical reference transmission connection in the historical preset period according to the following manner:

determining a performance difference value between a first historical performance detection value and a second historical performance detection value according to the first historical performance detection value corresponding to the historical optimized transmission connection in a historical preset period and the second historical performance detection value corresponding to the historical benchmark transmission connection;

and generating performance difference information containing the performance difference value and the historical optimized congestion control parameter adopted by the historical optimized transmission connection, wherein the performance difference information is used as the historical transmission performance difference information between the historical optimized transmission connection and the historical benchmark transmission connection in a historical preset period.

It should be noted that the performance difference value may be represented by a difference between the first historical performance detection value and the second historical performance detection value, or by a quotient between the first historical performance detection value and the second historical performance detection value, or the like.

It should be noted that, if the historical optimized transmission connection and the historical standard transmission connection are established in the historical preset period, the performance difference value between the first historical performance detection value and the second historical performance detection value is determined according to the first historical performance detection value corresponding to the historical optimized transmission connection and the second historical performance detection value corresponding to the historical standard transmission connection in the historical preset period.

For example, in a history preset period of 2T-3T, the history optimized congestion control parameter A adopted by the history optimized transmission connection 1 acquired by the server₃And a corresponding first historical performance detection value U₁（A₃) (ii) a Second historical performance detection value U corresponding to historical reference transmission connection 2₂(B) (ii) a The server determines a first historical performance detection value U₁（A₃) And a second historical performance measurement value U₂(B) The difference in performance between is diff (U)₁（A₃），U₂(B) For example diff (U)₁（A₃），U₂(B) Can be used to represent U₁（A₃) And U₂(B) The difference between or can be used to represent U₁（A₃) And U₂(B) Quotient of each other, etc.

The embodiment of the application determines the performance difference value diff (U) between the first historical performance detection value and the second historical performance detection value₁（A₃），U₂(B) After that, a difference value diff (U) containing the performance is generated₁（A₃），U₂(B) History optimized congestion control parameter A adopted by history optimized transmission connection₃Performance difference information of { A }₃，diff（U₁（A₃），U₂(B) In the historical transmission performance difference information, the historical optimized transmission connection and the historical benchmark transmission connection in the historical preset period are used as the historical transmission performance difference information.

It should be noted that, if at least two historical optimized transmission connections or at least two historical benchmark transmission connections are established in a historical preset period, a performance difference value between a first historical performance detection value and a second historical performance detection value is determined according to a first historical performance detection value corresponding to each historical optimized transmission connection or a second historical performance detection value corresponding to each historical benchmark transmission connection in the historical preset period; the system comprises at least two historical optimized transmission connections, at least two historical reference transmission connections and at least two data transmission connections, wherein the at least two historical optimized transmission connections adopt the same historical optimized congestion control parameters, and the at least two historical reference transmission connections adopt the same preset reference congestion control parameters; the first historical performance detection value or the second historical performance detection value is an average of first historical performance detection values of at least two historical optimized transmission connections or an average of second historical performance detection values of at least two historical baseline optimized transmission connections.

For example, in a history preset period of 2T-3T, a history optimized transmission connection established between the server and the client is, for example, a history optimized transmission connection 1 and a history optimized transmission connection 2, and a first history performance detection value U corresponding to the history optimized transmission connection 1 acquired by the server is obtained by the server₁（A₄) A first historical performance detection value U corresponding to the historical optimized transmission connection₂（A₄) The history optimized transmission connection 1 and the history optimized transmission connection 2 adopt the same history optimized congestion control parameter A₄(ii) a The historical reference transmission connection established between the server and the client is the historical reference transmission connection 3 as an example, and the server acquires a second historical performance detection value U corresponding to the historical reference transmission connection 3₃(B) (ii) a The server determines a first historical performance detection value U₁（A₄) And a first historical performance measurement value U₂（A₄) The average value between is U (A)₄) (ii) a Server determines U (A)₄) And a second historical performance measurement value U₃(B) The difference in performance between is diff (U (A)₄），U₃(B) For example, diff (U (A)₄），U₃(B) Can be used to represent U (A)₄) And U₃(B) The difference between them, or can be used to represent U (A)₄) And U₃(B) Quotient of each other, etc.

The embodiment of the application determines the performance difference value diff (U (A) between the first historical performance detection value and the second historical performance detection value₄），U₃(B) After that, a difference value diff (U (A)) containing the performance is generated₄），U₃(B) History optimized congestion control parameter A adopted by history optimized transmission connection₄Performance difference information of { A }₄，diff（U（A₄），U₃(B) ) as a history between the historically optimized transmission connection and the historically benchmark transmission connection within a historical preset periodAnd transmitting the performance difference information.

It should be noted that, if the history preset period corresponds to a plurality of history preset periods, the server performs the following operations for each history preset period respectively:

aiming at one historical preset period in a plurality of historical preset periods, determining a performance difference value between a first historical performance detection value and a second historical performance detection value according to a first historical performance detection value corresponding to a historical optimized transmission connection in the historical preset period and the second historical performance detection value corresponding to a historical benchmark transmission connection; and generating performance difference information containing the performance difference value and the historical optimized congestion control parameter adopted by the historical optimized transmission connection, wherein the performance difference information is used as the historical transmission performance difference information between the historical optimized transmission connection and the historical benchmark transmission connection in a historical preset period.

It should be noted that, if the historical optimized transmission connection and the historical standard transmission connection are established in each historical preset period, the performance difference value between the first historical performance detection value and the second historical performance detection value is determined according to the first historical performance detection value corresponding to the historical optimized transmission connection and the second historical performance detection value corresponding to the historical standard transmission connection in each historical preset period.

It should be noted that if the transmission performance adjustment request is not triggered by the server within the history preset periods 2T to 3T and 3T to 4T, the history optimized congestion control parameters that can be adopted by the history optimized transmission connection within 2T to 3T and 3T to 4T are the same and are the history optimized congestion control parameter a₅。

It should be noted that, if at least two history optimized transmission connections or at least two history reference transmission connections are established in each history preset period, a performance difference value between a first history performance detection value and a second history performance detection value is determined according to a first history performance detection value corresponding to each history optimized transmission connection or a second history performance detection value corresponding to each history reference transmission connection in each history preset period; the system comprises at least two historical optimized transmission connections, at least two historical reference transmission connections and at least two data transmission connections, wherein the at least two historical optimized transmission connections adopt the same historical optimized congestion control parameters, and the at least two historical reference transmission connections adopt the same preset reference congestion control parameters; the first historical performance detection value or the second historical performance detection value is an average of first historical performance detection values of at least two historical optimized transmission connections or an average of second historical performance detection values of at least two historical baseline optimized transmission connections.

It should be noted that one historical preset period corresponds to one historical transmission performance difference information.

When determining historical transmission performance difference information between the historical optimized transmission connection and the historical benchmark transmission connection in a historical preset period, if a first historical performance detection value corresponding to the historical optimized transmission connection in the historical preset period and a second historical performance detection value corresponding to the historical benchmark transmission connection are not obtained, the historical transmission performance difference information can be obtained according to the following modes in the embodiment of the application:

determining a relevant server corresponding to the server; the association server and the server belong to the same data center, and the service types of the association server and the server are the same; acquiring a third historical performance detection value corresponding to the reference optimized transmission connection and a fourth historical performance detection value corresponding to the reference standard transmission connection in a historical preset period; and determining a reference performance difference value between the third historical performance detection value and the fourth historical performance detection value; and generating performance difference information containing a reference performance difference value and a reference optimized congestion control parameter adopted by the reference optimized transmission connection as historical transmission performance difference information between the historical optimized transmission connection and the historical benchmark transmission connection in a historical preset period.

The reference optimized transmission connection is a transmission connection which is corresponding to the associated server and adopts a reference optimized congestion control parameter, and the reference standard transmission connection is a transmission connection which is corresponding to the associated server and adopts a preset standard congestion control parameter. The association server and the server are servers with the same designated characteristics; for example, the same specified characteristics may be attributed to the same data center and the same traffic type; or the same specified features of the embodiments of the present application may also be other specified features, and are not limited herein.

For example, if the specified characteristics are that the servers belong to the same data center (may be located in the same machine room), and the service types are the same, the machine room identifier of the server is 00001, and the service type is to process the client bidding service, then the other servers that are located in the machine room 00001 and the service type is to process the client bidding service are taken as the associated servers of the server.

It should be noted that, in the embodiment of the present application, the historical optimized congestion control parameter or the preset reference congestion control parameter, and the corresponding first historical performance detection value or the second historical performance detection value are shared by the associated server and the server, so that a problem that, in an initial stage, the optimal current optimized congestion control parameter cannot be determined quickly due to a small amount of data or no data of the historical optimized congestion control parameter used for the historical optimized transmission connection, the corresponding first historical performance detection value, the preset reference congestion control parameter used for the historical reference transmission connection, and the corresponding second historical performance detection value is avoided.

It should be noted that, in the embodiment of the present application, according to the third historical performance detection value corresponding to the reference-optimized transmission connection and the fourth historical performance detection value corresponding to the reference-optimized transmission connection within the obtained historical preset period, a manner of determining the reference performance difference value between the third historical performance detection value and the fourth historical performance detection value is the same as a manner of determining the performance difference value between the first historical performance detection value and the second historical performance detection value by the server according to the first historical performance detection value corresponding to the historical-optimized transmission connection and the second historical performance detection value corresponding to the historical-benchmark transmission connection within the obtained historical preset period.

In addition, in the embodiment of the present application, a manner in which the server generates the performance difference information including the reference performance difference value and the reference optimized congestion control parameter used for the reference optimized transmission connection is the same as the manner in which the server generates the performance difference information including the performance difference value and the historical optimized congestion control parameter used for the historical optimized transmission connection, and the specific implementation manner may refer to the description above, and details are not repeated here.

Step S202, the server determines the current optimized congestion control parameter of the current transmission connection in the current preset period based on the historical transmission performance difference information;

the current transmission connection is the transmission connection established in the current preset period; the transmission connection comprises an active transmission connection and an inactive transmission connection, wherein the active transmission connection is a successfully established transmission connection and the inactive transmission connection is an unsuccessfully established transmission connection.

In implementation, the current congestion control parameter includes an optimized control parameter for performing optimized congestion control on the current transmission connection, and a connection configuration ratio parameter corresponding to the current transmission connection.

It should be noted that, within a certain period of time, the resource demand in the network is greater than the current available resource, which may cause congestion, the congestion control algorithm is an algorithm for preventing congestion caused by injecting excessive data into the network, so that a router or a link is not overloaded, and different congestion control algorithms correspond to different congestion control parameters.

The following embodiments respectively describe the determination manners of two parameters included in the current congestion control parameter.

1. And determining the optimized control parameters in the current congestion control parameters.

Constructing a fitting function corresponding to a preset proxy model based on a performance difference value contained in the historical transmission performance difference information, a historical optimization congestion control parameter adopted by the historical optimization transmission connection and the preset proxy model; determining a confidence interval corresponding to the performance difference value in the fitting function based on a preset extraction function, and screening out a target performance difference value from the confidence interval; and determining an optimization control parameter corresponding to the target performance difference value according to the fitting function and the target performance difference value, and taking the optimization control parameter corresponding to the target performance difference value as the optimization control parameter in the current optimization congestion control parameter.

The fitting function is used for representing the mapping relation between the optimization control parameter and the performance difference value, and the target performance difference value is not smaller than the maximum value of the performance difference value in the historical transmission performance difference information.

It should be noted that, when the server determines the optimization control parameter based on the historical transmission performance difference information, a bayesian optimization model may be used. A Bayesian optimization algorithm is used for machine learning parameter adjustment in an artificial intelligence technology, and the main idea is that an optimized business objective function (generalized function, only input and output need to be specified, and the internal structure and mathematical properties do not need to be known) is given, and the posterior distribution of the business objective function is updated by continuously adding historical transmission performance difference information until the posterior distribution is basically fit with the real distribution. In short, the information of the last parameter is considered, so that the current parameter is better adjusted.

Optionally, when the bayesian optimization model is used to determine the optimized control parameters, the following formula may be used:

wherein, X^*In order to optimize the control parameters, X is a historical optimized congestion control parameter, R is a selection range of the historical optimized congestion control parameter, and U is a historical performance detection value.

The server in the embodiment of the application can determine the optimization control parameters according to the following modes:

(1) and the server constructs a fitting function corresponding to a preset proxy model based on the performance difference value contained in the historical transmission performance difference information, the historical optimization congestion control parameter adopted by the historical optimization transmission connection and the preset proxy model.

It should be noted that the preset proxy model may adopt a gaussian model or other models, and is not limited herein. In order to use a bayesian optimization model, an efficient way to model the distribution of the business objective function is needed. The gaussian process generates a multidimensional gaussian distribution that is sufficiently flexible to model any business objective function.

The expression of the service objective function in the embodiment of the application is not clear, only the input independent variable is X, and the output function value is X

The business objective function is approximated by a gaussian process.

Optionally, the server combines the historical transmission performance difference information with a gaussian model to construct a fitting function g (x) corresponding to the gaussian model, where the fitting function is used to represent a mapping relationship between the optimization control parameter and the performance difference value.

Fig. 3 is a schematic diagram for determining an optimized control parameter according to an embodiment of the present application. Curve 1 in fig. 3 is the constructed fitting function g (x).

Optionally, when determining the optimized control parameter in the embodiment of the present application, the following formula may be adopted:

wherein, X^*And f (.) is a preset extraction function for optimizing the control parameters, X is the historical optimized congestion control parameters, and R is the selection range of the historical optimized congestion control parameters.

(2) And the server determines a confidence interval corresponding to the performance difference value in the fitting function based on a preset extraction function, and screens out a target performance difference value from the confidence interval.

And the target performance difference value is not less than the maximum value of the performance difference values in the historical transmission performance difference information.

The preset extraction function may use an upper confidence boundary function (UCB) to determine a confidence interval of the performance difference value in the fitting function, that is, an area where the service objective function is most likely to be located, where the confidence interval is shown as an area formed between a dashed line 1 and a dashed line 2 in fig. 3.

After determining the confidence interval corresponding to the performance difference value in the fitting function, the server determines the maximum performance difference value diff based on the performance difference value contained in the historical transmission performance difference information_maxAnd a horizontal line is drawn at the position corresponding to the maximum performance difference value in fig. 3, and the next search point should be larger than diff_maxLarge or at least equal, i.e. the next explored point should lie above the horizontal line. Thus, the next sample is at diff_maxAnd between confidence intervals, assume diff_maxThe following samples are availableTo be discarded, the viewing area is reduced. The server is in diff_maxAnd searching for the next point between confidence intervals, e.g., as shown in FIG. 3, the performance difference value corresponding to the next point is diff₁And the server iterates the process until the maximum value of the performance difference value is searched, and the target performance difference value is determined.

(3) And the server determines the optimization control parameters corresponding to the target performance difference values according to the fitting function and the target performance difference values, and takes the optimization control parameters corresponding to the target performance difference values as the optimization control parameters in the current optimization congestion control parameters.

And substituting the screened target performance difference value into a fitting function by the server to determine the optimized control parameter corresponding to the target performance difference value.

2. And determining a connection configuration proportion parameter in the current congestion control parameters.

An optional implementation manner is that, in the embodiment of the present application, the server may determine the connection configuration ratio parameter corresponding to the current transmission connection according to the following manner:

and taking the ratio of the first historical performance detection value to the second historical performance detection value as a connection configuration proportion parameter.

It should be noted that, the larger the value of the historical performance detection value, the better the transmission performance is.

For example, in a historical preset period of 2T-3T, a first historical performance detection value corresponding to a historical optimized transmission connection 1 established between a server and a client is U₁（A₇) The second historical performance detection value corresponding to the historical reference transmission connection 2 is U₂(B) (ii) a The server sends U₁（A₇) And U₂(B) Ratio of between U and₁（A₇）/U₂(B) as a connection configuration ratio parameter.

For example, in a history preset period, history optimized transmission connections established by the server and the client are, for example, the history optimized transmission connection 3, the history optimized transmission connection 4, and the history optimized transmission connection 5, and first history performance detection results corresponding to the history optimized transmission connection 3, the history optimized transmission connection 4, and the history optimized transmission connection 5 are respectively U₃（A₈）、U₄（A₈）、U₅（A₈) (ii) a The historical reference congestion control parameters established between the server and the client are the historical reference transmission connection 6 and the historical reference transmission connection 7 as examples, and the second historical performance detection results corresponding to the historical reference transmission connection 6 and the historical reference transmission connection 7 are respectively U₆（B）、U₇(B) (ii) a Server determination U₃（A₈）、U₄（A₈）、U₅（A₈) Mean value therebetween is X₁，U₆（B）、U₇(B) Mean value therebetween is X₂Server sends X₁And X₂Ratio X between₁/X₂As a connection configuration ratio parameter.

It should be noted that, the server may also determine the connection configuration proportion parameter first, then determine the optimization control parameter, or execute the optimization control parameter in parallel, and therefore, the execution sequence of determining the optimization control parameter and the connection configuration proportion parameter by the server is not limited.

Another optional implementation manner is that, in the embodiment of the present application, the server may use a preset parameter configuration ratio as a connection configuration ratio parameter corresponding to the current transmission connection.

Step S203, the server divides the current transmission connection into a transmission connection to be optimized and a target reference transmission connection based on the current optimized congestion control parameter;

the server divides the current transmission connection into a transmission connection to be optimized and a target reference transmission connection based on a connection configuration proportion parameter in the current optimized congestion control parameter.

The connection configuration proportion parameter is used for expressing the proportion between the number of the transmission connections to be optimized in the current transmission connection and the number of the target reference transmission connection.

Specifically, the server determines a first number of transmission connections to be optimized in the current transmission connections and a second number of target reference transmission connections according to the connection configuration proportion parameter and the number of the current transmission connections in the current preset period; a first number of transport connections in the current transport connections are taken as transport connections to be optimized and a second number of transport connections are taken as target reference transport connections.

The transmission connection to be optimized is a transmission connection adopting an optimized control parameter, and the target reference transmission connection is a transmission connection adopting a preset reference congestion control parameter.

For example, if the connection configuration ratio parameter is 1:2 and the number of the current transmission connections is 36, it is determined that the first number of the transmission connections to be optimized in the current transmission connections is 12 and the second number of the target reference transmission connections is 24.

And step S204, the server respectively carries out transmission control on the transmission connection to be optimized and the target reference transmission connection according to the current optimized congestion control parameter and the preset reference congestion control parameter.

The server respectively performs transmission control on the transmission connection to be optimized and the target reference transmission connection according to the optimized control parameter in the current optimized congestion control parameter and the preset reference congestion control parameter.

Specifically, a first number of transmission connections to be optimized are subjected to congestion control by adopting an optimization control parameter, and a second number of target reference transmission connections are subjected to congestion control by adopting a preset reference congestion control parameter.

For example, if the server determines that the first number of the to-be-optimized transmission connections in the current transmission connections is 12 and the second number of the target reference transmission connections in the current transmission connections is 24, the server performs congestion control on the 12 to-be-optimized transmission connections by using the optimization control parameters, and performs congestion control on the 24 entry reference transmission connections by using the preset reference congestion control parameters.

In addition, it should be noted that all the embodiments described above may be applied to a Content Delivery Network (CDN), a video call scenario, or other application scenarios that use a transmission connection for data transmission, and are not limited herein.

As shown in fig. 4, an overall flowchart of a transmission control method provided in the embodiment of the present application includes the following steps:

step S401, a plurality of transmission connections are established between a client and a server;

step S402, when a server triggers a transmission performance adjustment request, determining a performance difference value between a first historical performance detection value and a second historical performance detection value according to a first historical performance detection value corresponding to a historical optimized transmission connection in a historical preset period and the second historical performance detection value corresponding to a historical reference transmission connection;

step S403, the server generates performance difference information containing a performance difference value and a history optimized congestion control parameter adopted by the history optimized transmission connection, and the performance difference information is used as the history transmission performance difference information between the history optimized transmission connection and the history reference transmission connection in a history preset period;

step S404, the server constructs a fitting function corresponding to a preset proxy model based on a performance difference value contained in the historical transmission performance difference information, a historical optimization congestion control parameter adopted by the historical optimization transmission connection and the preset proxy model;

s405, the server determines a confidence interval corresponding to the performance difference value in the fitting function based on a preset extraction function, and screens out a target performance difference value from the confidence interval;

step S406, the server determines an optimization control parameter corresponding to the target performance difference value according to the fitting function and the target performance difference value, and takes the optimization control parameter corresponding to the target performance difference value as an optimization control parameter in the current optimization congestion control parameter;

step S407, the server takes the ratio of the first historical performance detection value to the second historical performance detection value as a connection configuration proportion parameter corresponding to the current transmission connection;

the server may also determine the connection configuration proportion parameter corresponding to the current transmission connection, and then determine the optimization control parameter, or execute in parallel, so that the execution sequence of the server for determining the optimization control parameter and the connection configuration proportion parameter is not limited;

step S408, the server divides the current transmission connection into a transmission connection to be optimized and a target reference transmission connection based on the connection configuration proportion parameter;

and step S409, the server respectively performs transmission control on the transmission connection to be optimized and the target reference transmission connection according to the optimization control parameter and the preset reference congestion control parameter.

The following describes a transmission control method according to an embodiment of the present application with reference to a specific embodiment.

if 12 current transmission connections are established between the server and the client in the current preset period, the server determines that 4 to-be-optimized transmission connections adopt an optimized control parameter X according to a connection configuration proportion parameter 1:2 corresponding to the current transmission connections, and 8 entry mark reference transmission connections adopt a preset reference congestion control parameter B;

the server performs congestion control on 4 to-be-optimized transmission connections by adopting an optimization control parameter X, and performs congestion control on 8 standard transmission connections by adopting a preset standard congestion control parameter B.

In the following, with reference to fig. 6 to fig. 7, a transmission control method provided in an exemplary embodiment of the present application is described in conjunction with the optional application scenarios described above. It should be noted that the above application scenarios are only presented to facilitate understanding of the spirit and principles of the present application, and the embodiments of the present application are not limited in this respect. Rather, embodiments of the present application may be applied to any scenario where applicable.

As shown in fig. 6, a schematic flow chart of a transmission control method provided in the embodiment of the present application is shown, where the method may include the following steps:

step S601, when the transmission server determines that the transmission performance of the current transmission connection in the current preset period needs to be adjusted in the current preset period, the transmission server sends a transmission performance adjustment request to an optimization server;

The transmission performance adjustment request includes server information of the transmission server, where the server information may include but is not limited to:

the IP address of the transmission server and the information of the machine room to which the transmission server belongs.

It should be noted that, in the embodiment of the present application, a manner in which the transmission server determines that the transmission performance of the current transmission connection needs to be adjusted is the same as the manner in which the server triggers the transmission performance adjustment request in embodiment 1, and for a specific implementation, reference may be made to the description above, and details are not described here again.

In the embodiment of the application, before obtaining the historical transmission performance difference information between the historical optimized transmission connection and the historical benchmark transmission connection in the historical preset period, the optimization server needs to obtain the historical optimized congestion control parameter and the corresponding first historical performance detection value adopted by the historical optimized transmission connection in the historical preset period, and obtain the historical benchmark congestion control parameter and the corresponding second historical performance detection value adopted by the historical benchmark transmission connection in the historical preset period.

According to the embodiment of the application, the optimization server can acquire the historical optimized congestion control parameter and the corresponding first historical performance detection value adopted by the historical optimized transmission connection in the historical preset period, and the historical benchmark congestion control parameter and the corresponding second historical performance detection value adopted by the historical benchmark transmission connection in the historical preset period according to the following modes:

in the method 1, the optimization server pulls, according to the received transmission performance adjustment request, a history optimized congestion control parameter and a corresponding first history performance detection value which are adopted by the history optimized transmission connection in a history preset period, and pulls a history reference congestion control parameter and a corresponding second history performance detection value which are adopted by the history reference transmission connection in the history preset period from the log server.

In implementation, the optimization server sends a data request message containing a historical preset period to the log server according to the received transmission performance adjustment request; when the log server receives a data request message of the optimization server, the history optimization congestion control parameters and the corresponding first history performance detection values adopted by the history optimization transmission connection in the history preset period, the history benchmark congestion control parameters and the corresponding second history performance detection values adopted by the history benchmark transmission connection in the history preset period are collected and sent to the optimization server.

It should be noted that, when receiving the transmission performance adjustment request, the optimization server pulls the required congestion control parameter and the corresponding historical performance detection value from the log server, thereby reducing the storage space occupied by the optimization server.

If a history optimized transmission connection and a history reference transmission connection are established between the client and the transmission server in a history preset period, the optimization server acquires a history optimized congestion control parameter and a corresponding first history performance detection value adopted by the history optimized transmission connection, a history reference congestion control parameter and a corresponding second history performance detection value adopted by the history reference transmission connection in the history preset period from the log server;

for example, the history-optimized transport connection 1 established between the client and the transport server uses the history-optimized congestion control parameter a₁And the corresponding first historical performance detection value is U₁（A₁) The historical reference transmission connection 2 adopts a preset reference congestion control parameter B and the corresponding second historical performance detection value is U₂（B）。

The historical optimized congestion control parameters adopted by the historical optimized transmission connection in the historical preset period in the log server and the corresponding first historical performance detection values, the historical benchmark congestion control parameters adopted by the historical benchmark transmission connection and the corresponding second historical performance detection values can be stored in a database table structure mode.

For example, the database table structure of the embodiment of the present application may be as shown in table 1:

TABLE 1

If at least two historical optimized transmission connections or at least two historical benchmark transmission connections are established between the client and the transmission server in the historical preset period, the optimization server acquires the historical optimized congestion control parameters adopted by each historical optimized transmission connection and the corresponding first historical performance detection value from the log server, or acquires the preset benchmark congestion control parameters adopted by each historical benchmark transmission connection and the corresponding second historical performance detection value.

For example, the history-optimized transport connection 1 established between the client and the transport server uses the history-optimized congestion control parameter a₁And the corresponding first historical performance detection value is U₁（A₁) The history optimized transmission connection 2 adopts history optimized congestion control parameter A₁And the corresponding first historical performance detection value is U₂（A₁) The historical reference transmission connection 3 adopts a preset reference congestion control parameter B and the corresponding second historical performance detection value is U₃（B）。

The history optimized congestion control parameter and the corresponding first history performance detection value adopted by each history optimized transmission connection in the log server, or the preset reference congestion control parameter and the corresponding second history performance detection value adopted by each history reference transmission connection can be stored in a database table structure mode.

For example, the database table structure of the embodiment of the present application can be as shown in table 2:

TABLE 2

It should be noted that, if at least two history optimized transmission connections or at least two history reference transmission connections are established between the client and the transmission server, for the at least two history optimized transmission connections, a set of history optimized congestion control parameters and corresponding first history performance detection values are obtained from the log server, or for the at least two history reference transmission connections, a set of preset reference congestion control parameters and corresponding second history performance detection values are obtained from the log server; wherein the first historical performance detection value is an average of first historical performance detection values of the at least two historical optimized transmission connections, or the second historical performance detection value is an average of second historical performance detection values of the at least two historical reference transmission connections.

For example, the history optimized transmission connection 1 and the history optimized transmission connection 2 established by the transmission server and the client use the same history optimized congestion control parameter A₁Then the congestion control parameter a is optimized for the history₁Obtaining a history optimized congestion control parameter a from a log server₁The average of the corresponding first historical performance detection values, i.e. the first historical performance detection values corresponding to the historical optimized transmission connection 1 and the historical optimized transmission connection 2, is assumed to be U (a)₁) (ii) a If the historical reference transmission connection 3 and the historical reference transmission connection 4 established between the transmission server and the client use the same preset reference congestion control parameter B, acquiring a second historical performance detection value corresponding to the preset reference congestion control parameter B from the log server for the two historical reference transmission connections of the preset reference congestion control parameter B, namely an average value of the second historical performance detection values corresponding to the historical reference transmission connection 3 and the historical reference transmission connection 4, which is assumed to be u (B).

A group of historical optimized congestion control parameters and corresponding first historical performance detection values in the log server, or a group of preset benchmark congestion control parameters and corresponding second historical performance detection values may be stored in a database table structure.

For example, the database table structure of the embodiment of the present application can be as shown in table 3:

TABLE 3

In the method 2, when receiving the transmission performance adjustment request, the optimization server directly obtains the history optimized congestion control parameter and the corresponding first history performance detection value used for the history optimized transmission connection in the history preset period, the history reference congestion control parameter and the corresponding second history performance detection value used for the history reference transmission connection in the history preset period from the locally stored history optimized congestion control parameter and the corresponding first history performance detection value used for the history optimized transmission connection in the history preset period, and the history reference congestion control parameter and the corresponding second history performance detection value used for the history reference transmission connection in the history preset period.

The historical optimized congestion control parameters adopted by the historical optimized transmission connection and stored locally by the optimization server and the corresponding first historical performance detection values, the historical benchmark congestion control parameters adopted by the historical benchmark transmission connection in the historical preset period and the corresponding second historical performance detection values are periodically uploaded by the log server according to a second preset time length.

In practical application, the second preset time duration may be set according to a practical application scenario, for example, the second preset time duration may be set to 20 minutes, which is not limited herein.

If the historical optimized transmission connection and the historical benchmark transmission connection are established between the client and the transmission server in the historical preset period, the optimization server locally acquires the historical optimized congestion control parameter adopted by the historical optimized transmission connection and the corresponding first historical performance detection value, and the historical benchmark congestion control parameter adopted by the historical benchmark transmission connection in the historical preset period and the corresponding second historical performance detection value.

And the log server periodically uploads the historical optimized congestion control parameter adopted by the historical optimized transmission connection and the corresponding first historical performance detection value, the historical benchmark congestion control parameter adopted by the historical benchmark transmission connection in a historical preset period and the corresponding second historical performance detection value in a database table structure mode.

For example, the database table structure of the embodiment of the present application can be as shown in table 4:

TABLE 4

If at least two historical optimized transmission connections or at least two historical benchmark transmission connections are established between the client and the transmission server in the historical preset period, the optimization server locally acquires the historical optimized congestion control parameters adopted by each historical optimized transmission connection and the corresponding first historical performance detection value, or acquires the preset benchmark congestion control parameters adopted by each historical benchmark transmission connection and the corresponding second historical performance detection value.

And the log server periodically uploads the historical optimized congestion control parameter and the corresponding first historical performance detection value adopted by each historical optimized transmission connection or the preset reference congestion control parameter and the corresponding second historical performance detection value adopted by each historical reference transmission connection in a database table structure mode.

For example, the database table structure of the embodiment of the present application can be as shown in table 5:

TABLE 5

It should be noted that, if at least two historical optimized transmission connections or at least two historical benchmark transmission connections are established between the client and the transmission server, for at least two historical optimized transmission connections, a set of historical optimized congestion control parameters and corresponding first historical performance detection values are locally obtained from the optimization server, or for at least two historical benchmark transmission connections, a set of preset benchmark congestion control parameters and corresponding second historical performance detection values are obtained from the log server; wherein the first historical performance detection value is an average of first historical performance detection values of the at least two historical optimized transmission connections, or the second historical performance detection value is an average of second historical performance detection values of the at least two historical reference transmission connections.

And uploading a group of historical optimized congestion control parameters and corresponding first historical performance detection values or a group of preset reference congestion control parameters and corresponding second historical performance detection values by the log server in a database table structure mode.

For example, the database table structure of the embodiment of the present application can be as shown in table 6:

TABLE 6

The historical optimized congestion control parameters adopted by the historical optimized transmission connection and the corresponding first historical performance detection values stored in the log server, the historical benchmark congestion control parameters adopted by the historical benchmark transmission connection in the historical preset period and the corresponding second historical performance detection values are periodically uploaded to the log server by the transmission server or the client according to the first preset time length.

In practical application, the first preset time duration may be set according to a practical application scenario, for example, the first preset time duration is 10 minutes, which is not limited herein.

In the embodiment of the application, the optimization server obtains, by any one of the obtaining manners, a history optimized congestion control parameter and a corresponding first history performance detection value adopted by the history optimized transmission connection in the history preset period, and a history reference congestion control parameter and a corresponding second history performance detection value adopted by the history reference transmission connection in the history preset period.

It should be noted that, in the embodiment of the present application, a manner of determining a performance difference value between a first historical performance detection value and a second historical performance detection value according to an acquired first historical performance detection value corresponding to a historical optimized transmission connection in a historical preset period and a second historical performance detection value corresponding to a historical benchmark transmission connection is the same as a manner of determining a performance difference value between a first historical performance detection value and a second historical performance detection value according to an acquired first historical performance detection value corresponding to a historical optimized transmission connection in a historical preset period and a second historical performance detection value corresponding to a historical benchmark transmission connection by a server in embodiment 1.

In addition, after determining the performance difference value between the first historical performance detection value and the second historical performance detection value, the optimization server in the embodiment of the present application generates historical transmission performance difference information between the historical optimized transmission connection and the historical benchmark transmission connection in a historical preset period in the same manner as the server generates the historical transmission performance difference information between the historical optimized transmission connection and the historical benchmark transmission connection in the historical preset period in the embodiment 1, and the specific implementation manner may refer to the description above, and details are not repeated here.

When determining historical transmission performance difference information between the historical optimized transmission connection and the historical benchmark transmission connection in a historical preset period, if a first historical performance detection value corresponding to the historical optimized transmission connection in the historical preset period and a second historical performance detection value corresponding to the historical benchmark transmission connection are not obtained, the optimization server in the embodiment of the application can determine the historical transmission performance difference information according to the following modes:

determining an associated transmission server corresponding to the transmission server; acquiring a third historical performance detection value corresponding to the reference optimized transmission connection and a fourth historical performance detection value corresponding to the reference standard transmission connection in a historical preset period; and determining a reference performance difference value between the third historical performance detection value and the fourth historical performance detection value; and generating performance difference information containing a reference performance difference value and a reference optimized congestion control parameter adopted by the reference optimized transmission connection as historical transmission performance difference information between the historical optimized transmission connection and the historical benchmark transmission connection in a historical preset period.

The reference optimized transmission connection is a transmission connection which is corresponding to the associated transmission server and adopts reference optimized congestion control parameters, and the reference standard transmission connection is a transmission connection which is corresponding to the associated transmission server and adopts preset standard congestion control parameters.

The related transmission server and the transmission server are servers with the same designated characteristics; for example, the same specified characteristics may be attributed to the same data center and the same traffic type; or the same specified features of the embodiments of the present application may also be other specified features, and are not limited herein.

For example, if the specified characteristics are that the specified characteristics belong to the same data center (may be located in the same machine room), the service types are the same, the machine room identifier of the transmission server is 00001, and the service type is to process the client bidding service, then the other servers that are located in the machine room 00001 and the service type is to process the client bidding service are taken as the associated transmission servers of the transmission server.

It should be noted that, in the embodiment of the present application, the associated transmission server and the transmission server share the historical optimized congestion control parameter or the preset reference congestion control parameter, and the corresponding first historical performance detection value or the second historical performance detection value, so that a problem that, in an initial stage, the historical optimized congestion control parameter and the corresponding first historical performance detection value used for the historical optimized transmission connection, the preset reference congestion control parameter used for the historical reference transmission connection, and the corresponding second historical performance detection value are less or do not exist, so that the optimal current optimized congestion control parameter cannot be determined quickly is avoided.

It should be noted that, in the embodiment of the present application, a manner of determining a reference performance difference value between a third historical performance detection value and a fourth historical performance detection value according to a third historical performance detection value corresponding to the reference optimized transmission connection and a fourth historical performance detection value corresponding to the reference transmission connection in an obtained historical preset period by the optimization server is the same as a manner of determining a performance difference value between a first historical performance detection value and a second historical performance detection value according to a first historical performance detection value corresponding to the historical optimized transmission connection and a second historical performance detection value corresponding to the historical reference transmission connection in the obtained historical preset period by the server in embodiment 1.

In addition, the manner in which the optimization server generates the performance difference information including the reference performance difference value and the reference optimized congestion control parameter used for the reference optimized transmission connection in the embodiment of the present application is the same as the manner in which the server generates the performance difference information including the performance difference value and the historical optimized congestion control parameter used for the historical optimized transmission connection in embodiment 1, and the specific implementation manner may refer to the description above, and details are not repeated here.

Step S603, the optimization server determines the current optimized congestion control parameter of the current transmission connection based on the historical transmission performance difference information;

It should be noted that, in the embodiment of the present application, a manner of determining, by the optimization server, the optimized control parameter in the current optimized congestion control parameter based on the historical transmission performance difference information is the same as a manner of determining, by the server in embodiment 1, the optimized control parameter in the current optimized congestion control parameter based on the historical transmission performance difference information, and specific implementation manners may refer to the description above, and details are not repeated here.

In the embodiment of the application, after acquiring the first historical performance detection value corresponding to the historical optimized transmission connection and the second historical performance detection value corresponding to the historical benchmark transmission connection in the historical preset period, the optimization server may determine the connection configuration proportion parameter corresponding to the current transmission connection according to the following manner:

Wherein, the larger the value of the historical performance detection value is, the better the transmission performance is.

It should be noted that, in the embodiment of the present application, a manner of determining, by the optimization server, the connection configuration ratio parameter corresponding to the current transmission connection is the same as the manner of determining, by the server, the connection configuration ratio parameter corresponding to the current transmission connection in embodiment 1 above, and for a specific implementation, reference may be made to the description above, and details are not described here again.

It should be noted that, the optimization server may also determine the connection configuration proportion parameter first, then determine the optimization control parameter, or execute the optimization control parameter in parallel, and therefore, the execution sequence of determining the optimization control parameter and the connection configuration proportion parameter by the optimization server is not limited.

Step S604, the optimization server sends the current optimization congestion control parameter to the transmission server;

step S605, the transmission server receives the current optimized congestion control parameter sent by the optimization server, and divides the current transmission connection into a transmission connection to be optimized and a target reference transmission connection based on the current optimized congestion control parameter;

the transmission server divides the current transmission connection into a transmission connection to be optimized and a target reference transmission connection based on the connection configuration proportion parameter in the current optimized congestion control parameter.

Specifically, the transmission server determines a first number of transmission connections to be optimized in the current transmission connections and a second number of target reference transmission connections according to connection configuration proportion parameters corresponding to the current transmission connections and the number of the current transmission connections in a current preset period; a first number of transport connections in the current transport connections are taken as transport connections to be optimized and a second number of transport connections are taken as target reference transport connections.

For example, if the connection configuration ratio parameter is 1:3 and the number of the current transmission connections is 36, it is determined that the first number of the transmission connections to be optimized in the current transmission connections is 9 and the second number of the target reference transmission connections is 27.

Step S606, the transmission server respectively carries out transmission control on the transmission connection to be optimized and the target reference transmission connection according to the current optimized congestion control parameter and the preset reference congestion control parameter.

The transmission server respectively performs transmission control on the transmission connection to be optimized and the target reference transmission connection according to the optimized control parameter in the current optimized congestion control parameter and the preset reference congestion control parameter.

For example, if the transmission server determines that the first number of the to-be-optimized transmission connections in the current transmission connections is 9 and the second number of the target reference transmission connections in the current transmission connections is 27, the server performs congestion control on the 9 to-be-optimized transmission connections by using the optimized control parameters, and performs congestion control on the 27 entry-labeled reference transmission connections by using the preset reference congestion control parameters.

In addition, it should be noted that all the embodiments described above may be applied to a content distribution network, may also be applied to a video call scenario, and may also be applied to other application scenarios that use a transmission connection for data transmission, which is not limited herein.
