Method and system for flow control threshold value self-adjustment

Abstract

The invention provides a method and a system for flow control threshold value self-adjustment. The method comprises the following steps: determining a deviation degree between time consumption of a previous period of a current period and standard time consumption; in response to the fact that the deviation degree is greater than a preset time consumption deviation threshold value, calculating a flow control threshold value calculation value of the next period of the current period; if the flow control threshold value calculation value is greater than the upper extreme value of the flow control threshold value or less than the lower extreme value of the flow control threshold value, setting the upper extreme value or the lower extreme value as the flow control threshold value of the next period, otherwise, setting the flow control threshold value calculation value as the flow control threshold value of the next period.

Description

technical field [0001] The present invention relates to the field of IT and software development, more specifically, to a method and system for self-adjustment of flow control threshold. Background technique [0002] At present, all kinds of bus and gateway products basically have flow control based on the amount of messages, number of connections, flow size, current concurrent message volume, etc., and the flow control thresholds are pre-set fixed values, which cannot be provided according to the server. The busyness automatically adjusts flow control. [0003] The Chinese patent application "Method and System for Dynamically Adjusting Flow Control Threshold" (CN104408656A) proposes to adjust API flow control according to the failure rate (failure amount / request amount=failure rate) to reduce the failure rate. The failure rate is a way to adjust the flow control based on the business result, that is, the data after the failure occurs, which is an after-the-fact feedback. ...

Problems solved by technology

Therefore, in this patent application, the degradation rate is preset and cannot be dynamically changed based on historical operation data analysis results, etc., and can only achieve a decrease in the number of calls but cannot increase the number of calls based on the actual situation.

[0005] Therefore, although the current flow control method can automatically adjust the flow control according to the busyness of the server by dynamically adjusting the flow control threshold, it does not take into account the historical factors, current factors, expected factors, limit factors, etc. of flow control, and the flow control is not enough. Execution efficiency is affected by accuracy or the algorithm is too complicated. In order to realize the enrichment of flow control methods and the accuracy of flow control effects, make it more suitable for the actual situation of service provision, and ensure more stable service provision, it is hoped to provide an improved flow control method.
