Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a method, apparatus, and communication equipment for determining timeout parameters. Background Technology

[0002] Currently, the communication link timeout parameter is calculated as a multiple of the Round Trip Time (RTT). For example, in a wired local area network, where the RTT is within 1 millisecond, the link timeout parameter can be set to 50 times the RTT. This can detect communication interruption timeouts within 50 milliseconds, which meets practical usage requirements.

[0003] However, in the internet, communication link latency is relatively high, with an RTT of approximately 50 milliseconds. If the link timeout parameter is still set to 50 times the RTT, if the link communication is interrupted, it will take 50 x 50 = 2500 milliseconds to detect the interruption. In this case, the timeout is too long and unsuitable for practical needs. In reality, it might be necessary to detect link interruption timeout after 1000 milliseconds. Therefore, in this situation, setting the timeout to 20 times the RTT would be more appropriate.

[0004] Similarly, if the link RTT is 200 milliseconds, and the timeout is set to 50 times the RTT, then 200 x 50 = 10000 milliseconds. It would take 10 seconds to detect a link interruption timeout, which is also inappropriate. A more suitable timeout is 20 times the RTT, 200 x 20 = 4000 milliseconds, allowing for detection of a link interruption timeout after 4 seconds.

[0005] In summary, the existing method of setting the timeout parameter to a fixed multiple of the link RTT is only suitable for cases where the link RTT is fixed. When the link RTT changes dynamically and within a large range, the existing method of setting the timeout parameter cannot detect whether the link communication has been interrupted in a timely and accurate manner. Summary of the Invention

[0006] The purpose of this invention is to provide a method, apparatus, and communication device for determining timeout parameters, which solves the problem that existing timeout parameter setting methods cannot detect whether the link communication is interrupted in a timely and accurate manner.

[0011] Optionally, after determining the first timeout parameter corresponding to the communication link based on the RTT value, the method further includes:

[0012] Based on the RTT value and the first timeout parameter, a second timeout parameter corresponding to the communication link is determined, wherein the second timeout parameter is the link communication interruption timeout detection time;

[0013] The RTT value has a non-linear relationship with the second timeout parameter, and the second timeout parameter increases as the RTT value increases.

[0014] Optionally, determining the second timeout parameter corresponding to the communication link based on the RTT value and the first timeout parameter includes:

[0015] The product of the RTT value and the first timeout parameter is determined as the second timeout parameter.

[0016] Optionally, determining the first timeout parameter corresponding to the communication link based on the RTT value includes:

[0020] Optionally, before performing a subtraction function operation on the first value to obtain the second value, the method further includes:

[0021] The first value is then subjected to range restriction processing.

[0022] Optionally, the range restriction processing of the first value includes:

[0023] When the first value is greater than the second preset value, the first value is limited to the second preset value;

[0024] When the first value is less than the third preset value, the first value is restricted to the third preset value.

[0025] Optionally, the step of performing nonlinear processing on the RTT value to obtain a first value includes:

[0026] According to the formula: A = log a (b) Calculate the first value;

[0027] Where A is the first value; b is the RTT value, and b > 0; a is a positive integer greater than 1.

[0028] Optionally, the step of performing a subtraction operation on the first value to obtain the second value includes:

[0029] The difference between the fourth preset value and the first value is determined as the second value; wherein the fourth preset value is greater than the first value.

[0030] Optionally, determining the first timeout parameter based on the second value and the first preset value includes:

[0031] The product of the second value and the first preset value is determined as the timeout parameter.

[0032] To achieve the above objectives, embodiments of the present invention provide a device for determining timeout parameters, comprising:

[0033] The acquisition module is used to acquire the round-trip time (RTT) value of the communication link;

[0034] The first processing module is used to determine the first timeout parameter corresponding to the communication link based on the RTT value. The first timeout parameter is used to calculate the link communication interruption timeout detection time.

[0035] The RTT value has a non-linear relationship with the first timeout parameter, and the first timeout parameter decreases as the RTT value increases.

[0036] To achieve the above objectives, embodiments of the present invention provide a communication device, including a transceiver, a processor, a memory, and a program or instructions stored in the memory and executable on the processor; when the processor executes the program or instructions, it implements the method for determining timeout parameters as described above.

Thus, when the link's RTT changes dynamically and within a large range, the first timeout parameter of the communication link can be dynamically adjusted based on the changes in the RTT value to obtain a link communication interruption timeout detection time adapted to the current RTT value, ensuring timely and accurate detection of whether the link communication is interrupted.

[0043] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0044] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0045] In various embodiments of the present invention, it should be understood that the sequence number of each process described below does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0046] In addition, the terms "system" and "network" are often used interchangeably in this article.

[0047] In the embodiments provided in this application, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined based on A. However, it should also be understood that determining B based on A does not mean determining B solely based on A; B can also be determined based on A and / or other information.

[0048] like Figure 1As shown, a method for determining a timeout parameter according to an embodiment of the present invention includes the following steps:

[0049] Step 101: Obtain the round-trip time (RTT) value of the communication link;

[0050] It should be noted that the RTT value of a link can vary significantly at different times. For example, in the case of Wi-Fi and LTE networks, the link is easily subject to interference, and the communication rate is not stable, resulting in different RTT values ​​at different times.

[0051] Step 102: Determine the first timeout parameter corresponding to the communication link based on the RTT value. The first timeout parameter is used to calculate the link communication interruption timeout detection time. The RTT value and the first timeout parameter have a non-linear relationship, and the first timeout parameter decreases as the RTT value increases.

[0052] It should be noted that the RTT value detected on the same bearer link can vary significantly at different times. When the link is idle, the detected RTT is very small, only a few milliseconds, such as 3-5 milliseconds; when other traffic is being transmitted on the link, the detected RTT may be much larger, such as 50-100 milliseconds. Therefore, setting the first timeout parameter value based on the idle RTT becomes very mismatched under high link traffic conditions, making the judgment of tunnel timeouts very inaccurate.

[0053] In this embodiment, the first timeout parameter corresponding to the communication link is dynamically adjusted according to the round-trip time (RTT) value of the communication link, so that the RTT value and the first timeout parameter have a non-linear relationship, and the first timeout parameter decreases as the RTT value increases. In this way, based on the first timeout parameter, a link communication interruption timeout detection time that adapts to the current network latency can be obtained, ensuring timely and accurate detection of whether the link communication is interrupted.

[0054] In one embodiment, after step 102, the method further includes:

[0055] Based on the RTT value and the first timeout parameter, a second timeout parameter corresponding to the communication link is determined, wherein the second timeout parameter is the link communication interruption timeout detection time; wherein, the RTT value and the second timeout parameter have a non-linear relationship, and the second timeout parameter increases as the RTT value increases.

[0056] In this embodiment, the second timeout parameter is the link timeout detection time. For example, if the second timeout parameter is 2500 milliseconds, then if the link is interrupted, it is necessary to detect whether the link is interrupted after 2500 milliseconds.

[0057] In one specific embodiment, determining the second timeout parameter corresponding to the communication link based on the RTT value and the first timeout parameter includes:

[0058] The product of the RTT value and the first timeout parameter is determined as the second timeout parameter.

[0059] In this embodiment, since the first timeout parameter has a non-linear relationship with the RTT value, a second timeout parameter is determined based on the product of the RTT value and the first timeout parameter, making the second timeout parameter also have a non-linear relationship with the RTT value. This achieves a link communication interruption timeout detection time adapted to the current network latency based on the RTT value, ensuring timely and accurate detection of link communication interruptions.

[0060] In one embodiment, determining the first timeout parameter corresponding to the communication link based on the RTT value includes:

[0061] The RTT value is subjected to nonlinear processing to obtain a first value;

[0062] The second value is obtained by performing a subtraction operation on the first value.

[0063] The first timeout parameter is determined based on the second value and the first preset value.

[0064] In this embodiment, by performing a nonlinear transformation on the RTT value, the linear ratio problem between the timeout detection time and RTT can be avoided; by performing a subtraction function operation on the first value to obtain the second value, it is possible to achieve the following: the larger the RTT value, the smaller the final calculated first timeout parameter, and the smaller the RTT value, the larger the final calculated first timeout parameter; the first preset value is the experimental calibration quantity, which is used to adjust the second value to obtain the first timeout parameter.

[0065] In one embodiment, before performing a subtraction function operation on the first value to obtain the second value, the method further includes:

[0066] The first value is then subjected to range restriction processing.

[0067] In this embodiment, by limiting the range of the first value, it is possible to avoid the first value obtained by nonlinear processing being too large or too small due to the RTT being too large or too small, which would affect the accuracy of link interruption detection.

[0068] Specifically, in one embodiment, the range restriction processing of the first value includes:

[0069] When the first value is greater than the second preset value, the first value is limited to the second preset value;

[0070] When the first value is less than the third preset value, the first value is restricted to the third preset value.

[0071] This embodiment limits the first value to between a second preset value and a third preset value. For example, if the second preset value is set to 10, the first value greater than 10 is limited to 10; if the third preset value is 0, the first value less than 0 is limited to 0. Thus, after the RTT value exceeds a certain value, the set first timeout parameter will reach a minimum value. That is, the first timeout parameter has a minimum cutoff. For example, when the RTT value exceeds 1 second, the first timeout parameter is 10, meaning the timeout detection time is 10 times the RTT value. When the RTT is 1 second, the first timeout parameter is 10; when the RTT is 2 seconds, the first timeout parameter is still 10; when the RTT is 3 seconds, the first timeout parameter is still 10.

[0072] In the above embodiments, the first timeout parameter is not continuously reduced as the RTT value increases. This avoids the problem of misjudging the link communication interruption detection due to the first timeout parameter being too small, thus affecting the accuracy of the detection.

[0073] In one embodiment, the nonlinear processing of the RTT value to obtain a first value includes:

[0074] According to the formula: A = log a (b) Calculate the first value;

[0075] Where A is the first value; b is the RTT value, and b > 0; a is a positive integer greater than 1.

[0076] For example, first calculate the current RTT value of the link in milliseconds; then, calculate the logarithm of the RTT value with base 2, i.e., A = log2(RTT value).

[0077] In one embodiment, performing a subtraction function operation on the first value to obtain the second value includes:

[0078] The difference between the fourth preset value and the first value is determined as the second value; wherein the fourth preset value is greater than the first value.

[0079] In this embodiment, the fourth preset value is greater than the second preset value, and the fourth preset value can be set to different values ​​according to different actual situations.

[0080] In one embodiment, determining the first timeout parameter based on the second value and the first preset value includes:

[0081] The product of the second value and the first preset value is determined as the first timeout parameter.

[0082] In this embodiment, the first preset value is the product factor of the second value. In actual application, if the first timeout parameter calculated according to the actual situation is too large or too small, the first preset value can be adjusted according to the actual needs.

[0083] Below, with Taking a first preset value of 4, a second preset value of 10, a third preset value of 0, and a fourth preset value of 12 as examples, for different RTT values, based on the formulas: First timeout parameter = (12 - first value) × 4, Second timeout parameter = RTT × First timeout parameter, the first timeout parameter and the second timeout parameter are calculated. The specific results are shown in the table below:

[0084] RTT value (milliseconds) First timeout parameter (multiple) Second timeout parameter (milliseconds) 1 48 48 2 44 88 3 44 132 5 40 200 10 36 360 20 32 640 30 32 960 50 28 1400 100 24 2400 200 20 4000 500 16 8000 1000 12 12000

[0085] It should be noted that when calculating the first timeout parameter, the first value is obtained by rounding down the result of the calculation of log2 (RTT value).

[0086] As shown in the table above, both the first and second timeout parameters exhibit a non-linear relationship with the RTT value. Furthermore, as the RTT value increases, the first timeout parameter gradually decreases, while the second timeout parameter gradually increases. Both the first and second timeout parameters represent reasonably reasonable values.

[0087] It should be noted that the above solutions are not limited to specific communication devices and scenarios. In situations where the RTT of the communication link varies significantly due to the diversity of devices running the software, the wide range of product applications, or the actual communication scenarios, the first timeout parameter of the link can be dynamically adjusted using the embodiments of this application. This ensures that the fault interruption detection function of the communication link achieves the expected effect and meets the actual needs of product use.

The first timeout parameter is used to calculate the link communication interruption timeout detection time. The RTT value and the first timeout parameter have a non-linear relationship, and the first timeout parameter decreases as the RTT value increases. Based on the RTT value and the first timeout parameter, a second timeout parameter corresponding to the communication link is determined, wherein the second timeout parameter is the link communication interruption timeout detection time; wherein, the RTT value and the second timeout parameter have a non-linear relationship, and the second timeout parameter increases as the RTT value increases.

10. A communication device, comprising: A transceiver, a processor, a memory, and a program or instructions stored in the memory and executable on the processor; characterized in that, when the processor executes the program or instructions, it implements the method for determining timeout parameters as described in any one of claims 1-8.

11. A readable storage medium having a program or instructions stored thereon, characterized in that, When the program or instructions are executed by the processor, they implement the method for determining the timeout parameter as described in any one of claims 1-8.
