Data stream control method and device

Abstract

The embodiment of the invention provides a data stream control method and a data stream control device. The data stream control method comprises the following steps of: acquiring a dynamic data stream threshold value corresponding to a data pool of at least one class service; and configuring the dynamic data stream threshold value to the corresponding data pool so as to control the service data stream of a corresponding class of the data pool. The dynamic data stream threshold value can be configured for data pools of different class services, so that different data stream control can be flexibly provided for different class services, a service access system is not needed and the system resource occupation of service access is saved.

Description

technical field [0001] The invention relates to the technical field of overload control, in particular to a data flow control method and device. Background technique [0002] Overload usually means that the pressure on the system is greater than or equal to the preset tolerable pressure threshold. For example, the maximum processing capacity threshold of the system is to process 100,000 messages per second, but at a certain moment, it may need to process 200,000 This creates an overload. If the overload is not controlled, it may cause the system to be paralyzed and unable to work, etc. Therefore, an overload control mechanism is proposed to avoid damage caused by overload. [0003] At present, the overload control mechanism usually sets an overload threshold, such as a CPU occupation threshold, and an overload control strategy, such as denying access to services once overloaded. When the system is running, use the detection program to detect the CPU usage of the system. Wh...

Problems solved by technology

[0005] Due to the overload control mechanism, once the system is overloaded, it will refuse to access all services, that is, no matter what kind of service it is, all services will be denied access, and the CPU usage will drop rapidly. Once the system returns to normal, all services can be accessed again, and the CPU Occupancy rises rapidly, causing the system to be overloaded again, repeating itself, business jitter is serious, and the effect of overload control is not good

[0006] Moreover, the system needs to access business requests, so that the business code calls the API (Application Programming Interface, application program interface) at the business entry layer code to obtain the control flag, and knows whether it is overloaded, and the system access to business requests will inevitably consume a lot of resources. Resources, such as SOAP (Simple Object Access Protocol, Simple Object Access Protocol) packet unpacking, data format (XSD, XML Schema Definition, XML document structure definition) verification processing, etc., increase the load of the system to a certain extent , the overload control effect is not good
