Abstract

One or more embodiment of the present specification discloses a dynamic current limiting method, apparatus, and system for achieving globally accurate current limiting by dynamically adjusting a current limiting threshold. The method is applied to a current limiting device which establishes a long connection with a server cluster, includes obtaining a flow restriction state of each server in the server cluster and a total flow restriction threshold of the server cluster, wherein the flow restriction state comprises a current flow restriction state of each server in a current working cycle and / or a historical flow restriction state in a historical working cycle; determining a current limiting threshold of each server in a next duty cycle according to the current limiting state and the totalcurrent limiting threshold; performing a current limiting operation on each server according to the current limiting threshold.

Description

technical field [0001] This specification relates to the communication field, and in particular to a dynamic current limiting method, device and system. Background technique [0002] In scenarios with high concurrency and massive traffic, throttling has become an essential means. And because of the existence of long connections, the traditional stand-alone current limiting will cause the problem of load imbalance, causing users to be limited far before reaching the current limiting value. Therefore, cluster current limiting has become the only option, and how to achieve global and accurate current limiting in a distributed environment has always been a difficult problem. [0003] In the prior art, there are two commonly used cluster current limiting methods. One is to use the front-end current-limiting server to limit the current first, and then forward it to the real server. This method will have a single-point problem with the current-limiting server, that is, once the c...
