The determining method is: first determining a network volatility metric of the current network; and determining a timeout threshold of the current network according to the network volatility metric.

The determining the current network volatility metric includes: collecting the connection establishment time of the current N times network connection, where N is a natural number; performing uniformization on the maximum value of the connection establishment time to obtain a network of the current network Volatility measure.

And determining, according to the network volatility metric, a timeout threshold of the current network, by: querying a dual request dynamic policy rule table according to the network volatility metric to obtain a network volatility state of the current network; The timeout threshold corresponding to the network fluctuation state.

That is, the timeout threshold is determined according to the current network volatility metric; wherein the timeout threshold is compared with the network volatility reference standard by the current network volatility metric, thereby determining that the current network is sent. The timeout threshold of the first network request;

The step S120 further includes: the reference standard of the network volatility is a network fluctuation state and a timeout threshold corresponding to the indicator range of the network volatility metric in different stages; wherein, collecting a large amount Establishing a connection establishment time and a response time of the network connection, obtaining a correspondence data set of the connection establishment time and the corresponding response time; and dividing all connection establishment times in the correspondence data set into several stages, and as described in each stage The maximum and minimum values of the connection establishment time are normalized; the range of the minimum uniformization value to the maximum uniformization value obtained after each stage is determined as the index range of the network volatility measure; thus, according to the network volatility measure The indicator range of the indicator determines the corresponding network fluctuation state and the corresponding timeout time threshold, forms the network volatility reference standard, and stores the network volatility reference standard in the database to facilitate comparison of the network volatility measurement indicator call.

S130: When the time when the first network request is sent exceeds the timeout threshold, if the response data corresponding to the first network request is not received, the second network processing thread sends a second network request, where The second network request is the same as the content requested by the first network; for example, the second network request is the same as the content of the web page requested by the first network request. However, the second network request may be the same as the port number or the timestamp information carried by the first network request, or may be different. This embodiment is not limited.

S140: receiving, by the first network processing thread, response data of the first network request, or receiving, by the second network processing thread, response data of the second network request;

Further, in this embodiment, after transmitting the second network request, the first network processing thread and the second network processing thread are in a waiting phase, waiting to receive response data, and any one of the first network processing thread and the second network processing thread When the thread receives the response data corresponding to the first network request or the second network request, the thread returns the response data to the kernel layer, and closes another network request that does not receive the response data. For example, if the response data of the first network request is received, the second network processing thread is closed; or, if the response data of the second network request is received, the first network processing thread is closed.

That is, the detailed flowchart of step S130 in the previous embodiment.

As shown in FIG. 2, in a preferred embodiment, step S130 includes:

S121: Determine a timeout threshold according to a current network volatility measurement indicator (MA, Measure Amplitude);

That is, the network volatility metric of the current network is generated according to the connection establishment time of the last N network connections of the current network, and the timeout threshold is set according to the volatility metric of the network; If the value of N is greater than or equal to 1, the connection establishment time is multiple times, so that the timeout threshold is high, and the network volatility metric is the maximum uniformization value of the N connection establishment time;

S122: Determine whether the first network request receives the response data corresponding to the first network request within the timeout threshold.

If the response data corresponding to the first network request is received within the timeout threshold, the process ends;

If the response data corresponding to the first network request is not received within the timeout threshold, proceed to step S123;

S123: Create a second network processing thread, where the second network processing thread sends a second network request, where the second network request is the same as the content requested by the first network.

Network request. Therefore, the network request method can quickly send the secondary network request when the network is abnormal, and reduce the delay of the network request. In addition, the main request is generally a non-post-authentication and a non-preloaded network request.

In addition, during the implementation process, the number of times the network request is not limited to only sending the second network request. Under the network exception, if the network is stable but still does not receive the response data, the second network request may be sent after the second network request is sent. According to the second network request, the MA of the network sets a timeout threshold, and the time when the second network request is sent exceeds the timeout threshold. If the response data of the second network request is not received, the third thread sends the response data. a third network request, wherein the third network request is the same as the content requested by the first network, and then the first network request, the second network request, and the third network request both wait for corresponding response data, and receive the request in any one of the networks. After the corresponding response data, the other two network requests are closed by the kernel layer. Not only avoiding the burden of re-transmitting the network request, but also transmitting the third network request and receiving only one response data when the response data of the first network request or the second network request is not received and no network abnormality occurs. The backhaul can be performed, and it is not necessary to send the next network request when the network abnormality occurs in the prior art until the response data is received, thereby effectively reducing the delay caused by the network abnormality.

FIG. 10 is a network volatility reference standard according to an embodiment of the present application.

FIG. 11 is a cumulative distribution diagram of connection establishment time and corresponding response time according to an embodiment of the present application.

Referring to FIG. 9 to FIG. 11 , for example, in the implementation process, the default value of the initial measurement evaluation is initialized, denoted as A, and the default value may be 1000 (ie, the number of network connections 1000 times before the network request); Request, collect the connection establishment time of the last 5 network connections at the same time (this stage can collect and record the time taken by all the network connection establishments in the network layer through the data collection unit, the unit is ms, and if the network connection establishment fails, a setting will be recorded. The maximum value of the data sequence for calculating the collected connection establishment time is recorded as M; the maximum value M of the collected data sequence is uniformly processed. Specifically, the formula MA=(M- MINCT)/(MAXCT-MINCT)*100, so that the network volatility measure MA becomes a relative value of the maximum connection establishment time, and the value range is [0, 100], wherein in the specific application process, the MAXCT is set to 10000ms, MINCT is 0ms (the connection establishment time CT is not limited to this embodiment, and can also be set to other values). Therefore, the network volatility metric when the network request is sent can be obtained, and the network volatility state is indicated according to the network volatility metric. And, in During the implementation process, the maximum value of the collected data sequence is processed, and the purpose is to estimate the current network fluctuation state more reasonably and accurately, and ensure the hit rate when the secondary network request is issued. And the connection establishment time CT of the network connection is not in the range of 0-10000 ms proposed by the present embodiment in the network connection process, and can be confirmed according to the specific situation, so that the value of the network fluctuation measure MA is maintained at [0, 100). ], the quality of the network fluctuation can be directly determined according to the size of the network volatility measure MA.

Moreover, as shown in FIG. 9 and FIG. 10, the network fluctuation state is set according to network volatility. In this embodiment, it is set to five stages, that is, the network fluctuation state is divided into five from stable to undulating. Status: the network is very stable, the network is stable, the network fluctuation is small, the network fluctuation is large, and the network is very fluctuating. In the embodiment, the network fluctuation state of the five phases corresponds to the network volatility measurement index [0, 100], and in the implementation process The connection establishment time CT of the corresponding network connection in the middle is [0-10000 ms], and according to the connection establishment time of the network connection and the division of the network, the network volatility measurement index [0, 100] can be divided into five stages respectively. Network fluctuation status. This application effectively points out the relationship between the network volatility measurement index and the network volatility state. Since each network volatility state corresponds to the value range of a network volatility metric, it can pass a real-time cyber volatility metric MA. The value determines the network fluctuation status of the current network.

In addition, in the embodiment of the present application, as shown in FIG. 9 and referring to FIG. 8, the network fluctuation state is set according to network volatility. In this embodiment, the connection establishment time of the network connection is set by using a clustering algorithm. It is defined as five stages, that is, the network fluctuation state is divided into five states from stable to volatility: the network is very stable, the network is stable, the network fluctuation is small, the network fluctuation is large, and the network is very fluctuating, and in the embodiment, due to the five stages The network fluctuation state corresponds to the network volatility metric [0, 100], and the connection establishment time CT of the corresponding network connection in the implementation process is a range of [0-10000 ms], and the connection establishment time and network according to the network connection of the network connection The division of the network volatility metric [0, 100] can be divided into five phases corresponding to the network fluctuation state. At the same time, according to the connection establishment time CT and the response time RT and the cumulative distribution function for the connection establishment time CT and the response time RT, the timeout threshold T at a higher confidence can be effectively obtained. That is, by grouping a large number of connection establishment time and response time data, and establishing a cumulative distribution function, the network request is made in the network for the time T of the corresponding timeout time threshold under the value range of the different network volatility measurement indicators. Normally, the corresponding response data is received within the time T of the timeout threshold.

As shown in FIG. 10, the five ranges of the corresponding range of the network volatility measure MA [0, 100] are [0, 2), [2, 4), [4, 10), [10] , 30), [30, 100], and its corresponding network fluctuation status is: network is very stable, network stability, network volatility, network fluctuations, network non- Frequent fluctuations. The connection establishment time CT corresponding to the range of the network volatility measure [0, 2), [2, 4), [4, 10), [10, 30), [30, 100] is [0, 200), respectively. [200,400), [400,1000), [1000,3000), [3000,10000], the unit is ms; and according to the cumulative distribution function graph of the connection establishment time CT and the response time RT, it is known that the connection establishment time When the CT is at [0,200) milliseconds, there are about 98% of the network request response time RT is less than 3 seconds; when the connection establishment time CT is [200,400) milliseconds, about 97% of the network request response time RT is less than 4 seconds; When the connection establishment time CT is [400, 1000) milliseconds, about 97% of the network request response time RT is less than 5 seconds; when the connection establishment time CT is [1000, 3000) milliseconds, there are about 98% of network requests. The response time RT is less than 10 seconds. Therefore, the time T of the timeout threshold is obtained in the correspondence between the indicator range of the network volatility metric, the network volatility state, and the timeout threshold. The confidence time can be set according to the response time RT under the confidence level. The time T of the timeout threshold is exceeded; and during the implementation, the confidence setting may be 98%, 97%, 97%, 98%, 100%, respectively, so as to respond according to the confidence and the data within the confidence. The time RT and the connection establishment time CT result in the timeout thresholds being 3 seconds, 4 seconds, 6 seconds, 10 seconds, and 60 seconds, respectively. The time T of the timeout threshold is 60 seconds, that is, when the value of the network volatility measure MA is [30, 100], the maximum waiting time of the network set by the client, that is, no network data is returned within 60 seconds, Indicates that the timeout is abnormal and the response data cannot be received. That is, when the network is very fluctuating, the secondary network request will not be increased to increase the network load. Specifically, the network volatility reference standard can be seen in FIG. 10. As shown in FIG. 10, the network volatility reference standard can be used to make the standard range of the network volatility metric and the corresponding timeout threshold, and corresponding The network fluctuation state; in the embodiment, since the network fluctuation state is only the network fluctuation state reflected in the standard range of the network fluctuation measure, the network fluctuation state is not limited to the above. In the case of the embodiment, another network fluctuation state may be included, and the standard range of the network volatility metric is further divided into one phase, and the time of the network volatility metric and the timeout threshold is effectively matched.

As shown in FIG. 11, an embodiment of the present application establishes a connection establishment time into multiple stages by using a cumulative distribution function F _X (x)=P (X≤x) for the connection establishment time CT and the response time RT of the network connection. The cumulative distribution function of the time CT and the corresponding response time RT, that is, the establishment of the cumulative distribution function by the connection establishment time CT and the corresponding response time RT of each stage, forms the cumulative distribution function diagram, which is shown in FIG. It is shown that the cumulative distribution function of each stage is in the direction of the arrow from top to bottom: (0-2), (2-4), (4-6), (6-8), (8-10), (10) -20), (20-30), (30-40), (40-60), (60-80), (80-100) cumulative distribution of log pairs of CT pairs corresponding to connection establishment time by response time RT a function, wherein the response time RT and the connection establishment time CT are both in units of 10 ² milliseconds, and the minimum connection establishment time is recorded as 0 milliseconds, and the maximum connection time is recorded as 10000 milliseconds, thereby analyzing according to the cumulative distribution function graph The confidence level at each stage, and the time of the timeout threshold is obtained according to the confidence (refer to the relevant content of other embodiments) This is not repeated here).
