Problems solved by technology

[0005] However, the flow control scheme in the prior art will control the server to reject all user requests when the server is abnormal, causing the server to completely stop the service
Therefore, the flow control scheme of the prior art will waste server resources to a certain extent

Abstract

The invention provides a flow control method and system. The method comprises the following steps of computing a health data value of a server; gradually reducing a user request passing amount of theserver under a condition that the health data value is smaller than a preset health data value until the server meets one of a plurality of dynamic balance conditions, and determining the current userrequest passing amount as a target user request passing amount; when the health data value is larger than the preset health data value, gradually increasing the user request passing amount of the server until the server meets one of the dynamic balance conditions, and determining the current user request passing amount as the target user request passing amount; and determining the target user request passing amount as the number of the user requests received by the server. According to the method and the system, the user request can be controlled when the situation of the server is between abnormity and downtime, so that the user request quantity and the service capability can be dynamically balanced, and thus the utilization rate of the server resources is improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a flow control method and system. Background technique [0002] Currently, many systems have servers, which can receive user requests from many devices, and feed back request results to the devices after processing the user requests. Due to the limited server resources, if the amount of user requests received by the server exceeds the amount of user requests that can be processed, the load on the server will increase and the memory will be insufficient, resulting in server downtime. Therefore, currently, a flow control method for user requests is set in the server, so as to control the amount of user requests. [0003] The execution process of the current flow control method is: verify whether the server is normal, receive and process all user requests when the server is normal; reject all user requests when the server is abnormal, and start receiving until ...
