Detailed Description
So that the manner in which the features and aspects of the embodiments of the present invention can be understood in detail, a more particular description of the embodiments of the invention, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings.
Fig. 1 is an interaction diagram between a client and a server, and as shown in fig. 1, a communication connection is established between the client and the server, and in an embodiment, the communication connection between the client and the server is an HTTP2.0 connection. Since the HTTP2.0 connection is implemented based on a Transmission Control Protocol (TCP), that is, the HTTP2.0 implements data Transmission based on the TCP, the establishment of the communication connection between the client and the server needs to be implemented by three handshaking operations. After the client establishes a communication connection with the server, the client may send a request to the server by using the established communication connection, for example, request data related to a certain web page, where the data requested by the client may be pictures, texts, animations, and so on. And when the server receives the request sent by the client, the server returns corresponding data to the client. The above process is a process of normal interaction between the client and the server. However, at some point in time, the server experiences resource starvation for the established communication connection, such as: the server cannot receive the request sent by the client, and cannot process the received request, in this case, the server returns to the client an indication information that the window is 0, where the size of the window represents the number of requests that the client can send without waiting for the confirmation of the server, and if the client receives the indication information that the window is 0, it indicates that the client cannot continue to generate requests to the server (as indicated by the cross in the figure), and needs to wait until the window is updated to be greater than 0. At this time, the communication connection established between the client and the server is in an unavailable state.
In order to make the communication connection available, the occurrence of a communication connection of low quality should be avoided as much as possible. One manifestation of a low quality communication connection is: the event with the window 0 always occurs, that is, the client always receives the indication information of the window 0 sent by the server, so that the current communication connection always wastes time to wait for the update of the window size. Therefore, if a communication connection is detected to continuously generate an event with a window of 0, the communication connection is timely disconnected. After the communication connection is broken, the IP of the client can be replaced to establish a new communication connection with the server again.
How to detect the event that the communication connection continuously occurs with the window of 0 needs to be detected through an index, if the index is too sensitive, disconnection and reconnection of the communication connection are frequently caused, which also reduces the utilization rate of the communication connection. Therefore, the embodiment of the present invention provides a reasonable detection index to determine whether the current communication connection has become poor and is highly likely to maintain the poor state for a future period of time, and if so, the communication connection needs to be disconnected and reestablished. If only occasional network fluctuations of the communication connection occur, no processing is done.
The detection indexes of the embodiment of the invention are as follows: for a period of time, it is detected whether the event with the window of 0 continues to occur for a certain number of times, and it is predicted that such an event is still likely to continue to occur for a future period of time.
Fig. 2 is a first schematic flowchart of a connection processing method according to an embodiment of the present invention, and as shown in fig. 2, the connection processing method includes the following steps:
step 201: the method comprises the steps that a first communication connection is established between a client and a server, wherein if the client receives first window indication information sent by the server, the client indicates that the client cannot send data to the server by using the first communication connection.
In the embodiment of the invention, the client can be a mobile phone, a notebook, a desktop and other terminal equipment.
In the embodiment of the present invention, the first communication connection established between the client and the server may be an HTTP2.0 connection. And a first communication connection is established between the client and the server through three-way handshake. Here, one first communication connection may be established between the client and the server, or a plurality of first communication connections may be established. If a plurality of first communication connections are established between the client and the server, each first communication connection can be processed by the scheme of the embodiment of the invention.
In the embodiment of the present invention, the first window indication information refers to indication information that a window is 0, and certainly, the first window indication information is not limited to the indication information that the window is 0, and may also be indication information that the window is a certain smaller value, for example, the window is indication information that the window is less than or equal to a preset value, where the preset value is 5.
In the embodiment of the present invention, if the client receives the first window indication information sent by the server, it indicates that the client cannot send data to the server by using the first communication connection.
For example: when the client receives the indication information that the window sent by the server is 0, the client cannot send data to the server by using the first communication connection, otherwise, the server is overloaded to work, the problem of downtime is caused, or the server discards the data sent by the client.
Step 202: and counting the time when the client receives the first window indication information within a first preset time length to obtain a time set.
In the embodiment of the present invention, the starting time of the first preset time duration is T1, the ending time is T2, and T2 is greater than T1.
In an embodiment, a time point when the client receives the first window indication information for the first time is taken as a time T1, and a time set is obtained by counting the times when the first window indication information is received within M consecutive time periods from a time T1, where T1+ M is T2, and the unit of the time and the time period may be seconds, minutes, hours, and the like.
As shown in fig. 3, after the client establishes the first communication connection with the server, when the client receives the first window indication information for the first time, it records that the current time is t0(ii) a When the first window indication information is received for the second time, the current moment is recorded as t1(ii) a When the first window indication information is received for the third time, the current time is recorded as t2(ii) a When the first window indication information is received for the fourth time, the current time is recorded as t3(ii) a When the first window indication information is received for the fifth time, the current time is recorded as t4. Wherein, t0The time is the time T1 in the scheme4The time is T2 in the above scheme.
In the embodiment of the invention, the client stores each time in the time set through the array. As shown in fig. 4, fig. 4 is a structural diagram of a one-dimensional array, and the client may store the counted time into the one-dimensional array by using a pointer.
Step 203: and calculating normal distribution corresponding to the time set.
In the embodiment of the invention, based on each time in the time set, the average value and the variance value corresponding to the time set are calculated; and calculating normal distribution corresponding to the time set based on the average value and the variance value corresponding to the time set, wherein the normal distribution indicates the probability parameter corresponding to each time.
For example: the time set comprises the following times: t is t0、t1、t2、t3、t4Calculating an average value (μ) corresponding to the time set by the following formula:
Figure BDA0001270559320000071
calculating a variance value (sigma) corresponding to the time set2) Obtained by the following formula:
Figure BDA0001270559320000072
calculating the normal distribution (f (t)) corresponding to the time set by the following formula:
Figure BDA0001270559320000073
fig. 5 is a schematic diagram of a normal distribution curve, and as shown in fig. 5, a probability parameter corresponding to each time may be determined by the normal distribution curve, where the probability parameter indicates a possibility that the first window indication information is received at the time.
Step 204: and when the probability parameter corresponding to the target moment is determined to be larger than or equal to the preset value based on the normal distribution, the first communication connection between the client and the server is disconnected.
In the embodiment of the invention, one or more target moments are selected from the moment T2 to the moment T3, wherein the distance between the moment T3 and the moment T2 is less than or equal to a second preset time length, and T3 is greater than T2.
As shown in fig. 6, the times when the client receives the first window indication information between time T1 and time T2 are: t is t0、t1、t2、t3、t4It may be desirable to select one or more target times, e.g. two target times T, within a relatively short time frame after time T25And t6And substituting the two moments into the formula (3) to obtain corresponding probability parameters, and then judging whether the probability parameters are greater than or equal to preset values. Here, the preset value may be a minimum value such as three thousandths, and if the probability parameter corresponding to the target time is greater than or equal to the preset value, it indicates that the probability that the target time receives the first window indication information is maximum, and it is considered that the first window indication information will be received.
In the embodiment of the present invention, if it is determined based on the normal distribution that the probability parameter corresponding to the target time is greater than or equal to the preset value, it indicates that the client will receive the first window indication information in the future, in this case, the first communication connection needs to be disconnected, and after the first communication connection is disconnected, the second communication connection may be reestablished to continue to implement message pushing between the client and the server. If the probability parameter corresponding to the target moment is smaller than the preset value, it indicates that the client will not receive the first window indication information in the future, and in this case, the first communication connection needs to be maintained.
According to the technical scheme of the embodiment of the invention, the time stamp record of the event with the occurrence window of 0 in a period of time is collected, the normal distribution curve is calculated, and whether the event with the future window of 0 still occurs is judged through the normal distribution curve, so that the communication connection is reasonably maintained.
Fig. 7 is a second flowchart illustrating a connection processing method according to an embodiment of the present invention, and as shown in fig. 7, the connection processing method includes the following steps:
step 701: the method comprises the steps that a first communication connection is established between a client and a server, wherein if the client receives first window indication information sent by the server, the client indicates that the client cannot send data to the server by using the first communication connection.
In the embodiment of the invention, the client can be a mobile phone, a notebook, a desktop and other terminal equipment.
In this embodiment of the present invention, the first communication connection established between the client and the server may be an HTTP2.0 connection. And a first communication connection is established between the client and the server through three-way handshake. Here, one first communication connection may be established between the client and the server, or a plurality of first communication connections may be established. If a plurality of first communication connections are established between the client and the server, each first communication connection can be processed by the scheme of the embodiment of the invention.
In the embodiment of the present invention, the first window indication information refers to indication information that a window is 0, and certainly, the first window indication information is not limited to the indication information that the window is 0, and may also be indication information that the window is a certain smaller value, for example, the window is indication information that the window is less than or equal to a preset value, where the preset value is 5.
In the embodiment of the present invention, if the client receives the first window indication information sent by the server, it indicates that the client cannot send data to the server by using the first communication connection.
For example: when the client receives the indication information that the window sent by the server is 0, the client cannot send data to the server by using the first communication connection, otherwise, the server is overloaded to work, the problem of downtime is caused, or the server discards the data sent by the client.
Step 702: and counting the time when the client receives the first window indication information within a first preset time length to obtain a time set.

In an embodiment, a time point when the client receives the first window indication information for the first time is taken as a time T1, and a time set is obtained by counting the times when the first window indication information is received within M consecutive time periods from a time T1, where T1+ M is T2, and the unit of the time and the time period may be seconds, minutes, hours, and the like.
As shown in fig. 3, after the client establishes the first communication connection with the server, when the client receives the first window indication information for the first time, it records that the current time is t0(ii) a When the first window indication information is received for the second time, the current moment is recorded as t1(ii) a When the first window indication information is received for the third time, the current time is recorded as t2(ii) a When the first window indication information is received for the fourth time, the current time is recorded as t3(ii) a When the first window indication information is received for the fifth time, the current time is recorded as t4. Wherein, t0The time is the time T1 in the scheme4The time is T2 in the above scheme.
In the embodiment of the invention, the client stores each time in the time set through the array. As shown in fig. 4, fig. 4 is a structural diagram of a one-dimensional array, and the client may store the counted time into the one-dimensional array by using a pointer.
Step 703: and judging whether the number of the time points included in the time point set is greater than or equal to a threshold value, if so, executing step 705, and if not, executing step 704.
Here, if the number of times included in the time set is greater than or equal to the threshold value, it indicates that the first window indication information is frequently received within the preset duration, and it is necessary to predict whether the first window indication information is received at a future time through normal distribution.
Step 704: the first communication connection is maintained.
Here, maintaining the first communication connection means: the first communication connection is maintained.

Step 706: judging whether the probability parameter corresponding to the target moment is greater than or equal to a preset value or not based on the normal distribution; if yes, go to step 707; if not, step 704 is performed.
In the embodiment of the invention, one or more target moments are selected from the moment T2 to the moment T3, wherein the distance between the moment T3 and the moment T2 is less than or equal to a second preset time length, and T3 is greater than T2.
As shown in fig. 6, the times when the client receives the first window indication information between time T1 and time T2 are: t is t0、t1、t2、t3、t4It may be desirable to select one or more target times within a relatively short time period after time T2, for example, to select two target times T5And t6Substituting the two moments into the formula (3) to obtain corresponding probability parameters, and then judging whether the probability parameters are larger than or equal to preset values. Here, the preset value may be a minimum value such as three thousandths, and if the probability parameter corresponding to the target time is greater than or equal to the preset value, it indicates that the probability that the first window indication information is received at the target time is maximum, and it is considered that the first window indication information will be received.
Step 707: the client disconnects the first communication connection with the server.
In the embodiment of the present invention, if it is determined based on the normal distribution that the probability parameter corresponding to the target time is greater than or equal to the preset value, it indicates that the client will receive the first window indication information in the future, in this case, the first communication connection needs to be disconnected, and after the first communication connection is disconnected, the second communication connection may be reestablished to continue to implement message pushing between the client and the server. If the probability parameter corresponding to the target moment is smaller than the preset value, it indicates that the client will not receive the first window indication information in the future, and in this case, the first communication connection needs to be maintained.
According to the technical scheme of the embodiment of the invention, the time stamp record of the event with the occurrence window of 0 in a period of time is collected, the normal distribution curve is calculated, and whether the event with the future window of 0 still occurs is judged through the normal distribution curve, so that the communication connection is reasonably maintained.

And a first communication connection is established between the client and the server through three-way handshake. Here, one first communication connection may be established between the client and the server, or a plurality of first communication connections may be established. If a plurality of first communication connections are established between the client and the server, each first communication connection can be processed by the scheme of the embodiment of the invention.

In the embodiment of the present invention, the starting time of the first preset time duration is T1, the ending time is T2, and T2 is greater than T1.
In an embodiment, a time point when the client receives the first window indication information for the first time is taken as a time T1, and a time set is obtained by counting the times when the first window indication information is received within M consecutive time periods from a time T1, where T1+ M is T2, and the unit of the time and the time period may be seconds, minutes, hours, and the like.
As shown in fig. 3, after the client establishes the first communication connection with the server, when the client receives the first window indication information for the first time, it records that the current time is t0(ii) a When the first window indication information is received for the second time, the current moment is recorded as t1(ii) a When the first window indication information is received for the third time, the current time is recorded as t2(ii) a When the first window indication information is received for the fourth time, the current time is recorded as t3(ii) a When the first window indication information is received for the fifth time, the current time is recorded as t4. Wherein, t0The time is the time T1 in the scheme4The time is T2 in the above scheme.
In the embodiment of the invention, the client stores each time in the time set through the array. As shown in fig. 4, fig. 4 is a structural diagram of a one-dimensional array, and the client may store the counted time into the one-dimensional array by using a pointer.
Step 803: and calculating normal distribution corresponding to the time set.
In the embodiment of the invention, based on each time in the time set, the average value and the variance value corresponding to the time set are calculated; and calculating normal distribution corresponding to the time set based on the average value and the variance value corresponding to the time set, wherein the normal distribution indicates the probability parameter corresponding to each time.
Fig. 5 is a schematic diagram of a normal distribution curve, and as shown in fig. 5, a probability parameter corresponding to each time may be determined by the normal distribution curve, where the probability parameter indicates a possibility that the first window indication information is received at the time.
Step 804: determining a range with probability parameters larger than the preset value as a reference range based on the normal distribution; and when the target time is within the reference range, determining that the probability parameter corresponding to the target time is greater than or equal to a preset value.
In the embodiment of the invention, one or more target moments are selected from the moment T2 to the moment T3, wherein the distance between the moment T3 and the moment T2 is less than or equal to a second preset time length, and T3 is greater than T2.
As shown in fig. 6, the times when the client receives the first window indication information between time T1 and time T2 are: t is t0、t1、t2、t3、t4It may be desirable to select one or more target times, e.g. two target times T, within a relatively short time frame after time T25And t6And substituting the two moments into the formula (3) to obtain corresponding probability parameters, and then judging whether the probability parameters are greater than or equal to preset values. Here, the preset value may be a minimum value such as three thousandths, and if the probability parameter corresponding to the target time is greater than or equal to the preset value, it indicates that the probability that the target time receives the first window indication information is maximum, and it is considered that the first window indication information will be received.
Suppose that the mean and variance values for the time set are μ and σ, respectively2From the normal distribution characteristics, the probability outside the (μ -3 σ, μ +3 σ) interval is three thousandths, and is considered to be three thousandths in practiceAre unlikely events to occur. Therefore, if a certain time in the future is beyond (μ -3 σ, μ +3 σ), the client is considered to not receive the first window indication information, which of course also means that the probability that the client receives the first window indication information is less than three thousandths. On the contrary, if a certain time in the future is within (μ -3 σ, μ +3 σ), the client is considered to receive the first window indication information, which of course also means that the probability that the client receives the first window indication information is greater than or equal to three thousandths.
Step 805: and when the probability parameter corresponding to the target moment is determined to be larger than or equal to the preset value based on the normal distribution, the first communication connection between the client and the server is disconnected.
In the embodiment of the present invention, if it is determined based on the normal distribution that the probability parameter corresponding to the target time is greater than or equal to the preset value, it indicates that the client will receive the first window indication information in the future, in this case, the first communication connection needs to be disconnected, and after the first communication connection is disconnected, the second communication connection may be reestablished to continue to implement message pushing between the client and the server. If the probability parameter corresponding to the target moment is smaller than the preset value, it indicates that the client will not receive the first window indication information in the future, and in this case, the first communication connection needs to be maintained.
According to the technical scheme of the embodiment of the invention, the time stamp record of the event with the occurrence window of 0 in a period of time is collected, the normal distribution curve is calculated, and whether the event with the future window of 0 still occurs is judged through the normal distribution curve, so that the communication connection is reasonably maintained.
