Description

Technical Field

[0001] The present invention relates to the technical field of flow control, and in particular to a flow control method, system, computer device and non-volatile computer-readable storage medium based on shared memory. Background Art

[0002] Currently, flow control refers to the phenomenon of overload of an application service in a certain service area or module due to some unexpected factors, such as service failure or unexpected increase in service volume. The cause of this failure cannot be resolved within a tolerable period of time. The root cause of the failure may be unclear or definite, but it is difficult to solve due to technical and resource factors. Therefore, a temporary workaround is implemented to avoid avalanche-like system failures caused by a single point failure.

[0003] Currently, the JAVA technology stack mainly uses the Hystrix fault-tolerant system to control the avalanche effect of services. When it determines that the backend service is unavailable, it uses alternative response options to provide a workaround. However, each request is still sent to the backend service. Traditional C technology stack systems are often payment transaction systems. They are truly irreplaceable in payment and require direct results. However, traditional C technology stack systems often lack available middleware modules and are insufficient in their ability to control service traffic. In case of emergencies, manual traffic control is usually required.

[0004] Therefore, the existing technology still needs to be improved and enhanced. Summary of the Invention

[0117] S400: If there is a flow control policy corresponding to the policy target, determine whether the flow information of the service flow meets the degradation target;

[0118] S500: If the flow information of the service flow meets the degradation target, determine whether the flow value of the service flow exceeds a preset flow threshold;

[0119] S600: If the traffic value of the service traffic exceeds a preset traffic threshold, degrade the service traffic.

[0120] Furthermore, in the shared memory-based flow control method, the flow control strategy further includes a degradation strategy;

[0121] In step S600, if the flow rate value of the service flow exceeds a preset flow rate threshold, downgrading the service flow includes:

[0122] If the traffic value of the service traffic exceeds a preset traffic threshold, the random number is compared with the degradation policy to determine whether the random number is consistent with the degradation policy;

[0123] If so, the service traffic is downgraded.

[0124] Specifically, in this embodiment, the degradation processing of the service traffic may also include fuse processing of the service traffic.

[0125] Furthermore, in the shared memory-based flow control method, the step of determining whether the random number complies with the degradation strategy comprises:

[0126] If not, the service traffic will be released.

[0127] Furthermore, in the shared memory-based traffic control method, in step S400, if there is a traffic control policy corresponding to the policy target, determining whether the traffic information of the service traffic meets the degradation target includes:

[0128] If there is a flow control policy corresponding to the policy target, determining whether the degradation policy in the corresponding flow control policy is 0% or 100% or 0<100%;

[0129] If the degradation policy in the corresponding traffic control policy is 0%, the service traffic is released;

[0130] If the degradation policy in the corresponding flow control policy is 100%, the service flow is subjected to fuse processing;

[0131] If the corresponding degradation policy in the traffic control policy is 0<100%, it is determined whether the traffic information of the service traffic meets the degradation target.

[0132] Furthermore, in the shared memory-based flow control method, the step of determining whether a flow control policy corresponding to the policy target exists in the shared memory includes:

Due to real-time access based on shared memory, it has strong scalability, and manual intervention can be performed through the operation platform to adjust the shared memory configuration to achieve downgrade or fuse policies. It is also possible to add and modify the automatic matching policy threshold in the memory, and flexibly apply downgrade and fuse processing, which can effectively avoid avalanche-type system failures caused by service overload or back-end service unavailability, improve the results obtained by customers who fail to pay during payment overload, and reduce the further brewing of customer emotions caused by failed services.

[0139] Of course, in the present invention, a mode can be reused and managed in multiple modules through shared memory, but in actual use, it is implemented through a non-absolute 100% fuse method. For example, 95% of the traffic can be fused, and 5% of the traffic continues to be sent to the backend to detect service recovery. Once the backend service is restored and available, the fuse is immediately released.
