Service flow limiting method and device

Abstract

The invention provides a service flow limiting method and device. The method comprises the following steps: receiving a flow limiting strategy set by a user; the flow limiting strategy is issued to probes of node servers of all services; and carrying out current limiting by utilizing the probe according to the current limiting strategy. According to the invention, the problem of flow limiting between nodes in the distributed micro-service is solved, the method is non-invasive to the application program, and the application program is non-perceptible to the device. Moreover, the traditional current-limiting middleware can only achieve the interface-level current-limiting capability for the target application, and the current-limiting algorithm is single and low in variability, while the scheme provided by the invention can achieve the method-level current-limiting capability for the target application, and the accuracy of the current-limiting function is improved.

Description

technical field [0001] The present invention relates to data processing technology, specifically a service flow limiting method and device. Background technique [0002] With the popularity of distributed micro-services, the safe and reliable current-limiting and fusing function between internal services has become more and more important. There are two traditional ways of current-limiting and fusing. flow, and the other is to implant current-limiting and circuit-breaking functions in related frameworks or programs in microservices. [0003] The flow is limited from the gateway or load balancer where the service is accessed. This kind of flow control has a relatively coarse control granularity, and it is impossible to limit the flow between each service in the internal cluster of the microservice, or to limit the flow of each interface in the internal cluster. Precise current limiting between calls. [0004] Implanting the current-limiting fuse function in the relevant fra...

[0003] The flow is limited from the gateway or load balancer where the service is accessed. This kind of flow control has a relatively coarse control granularity, and it is impossible to limit the flow between each service in the internal cluster of the microservice, or to limit the flow of each interface in the internal cluster. Precise current limiting between calls

[0004] Embed the current-limiting fuse function in the relevant framework or program in the microservice. This method has strong coupling to the business program and is not suitable for the upgrade of the current-limiting function in the future.
