Abstract

The invention discloses a dynamic global traffic limiting method and device, and relates to the technical field of computers. A specific embodiment of the method comprises the steps of obtaining request processing data of each server in a server cluster in a current time window; according to the request processing data of each server in the current time window, determining a total traffic limitingthreshold of the server cluster in the next time window and a resource allocation proportion of each server; determining a traffic limiting threshold of each server in the next time window accordingto the total traffic limiting threshold and the resource allocation proportion of each server; and executing a traffic limiting operation on each server according to the traffic limiting threshold ofeach server in the next time window. According to the embodiment, the total traffic limiting threshold of the server cluster and the traffic limiting threshold of each server can be automatically adjusted according to the request processing data of each server in the server cluster, so that the traffic limiting effect is greatly improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for dynamic global current limiting. Background technique [0002] The processing power of a backend system is limited. When the amount of requests increases sharply or a problem occurs in an internal subsystem, the performance and stability of the system will usually drop significantly, and even a chain reaction will occur, causing the entire system to enter an unavailable state. In order to ensure the availability of the system, a necessary measure is to limit the flow of received requests to avoid the system being affected by large flow fluctuations in a short period of time. [0003] The existing global current limiting is generally based on the fixed threshold value implemented by setting the counter in the distributed cache, and the current limiting threshold cannot be automatically adjusted according to the system situation.
