Embodiment Construction

[0023] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0024] Aiming at the flow control problem faced by the distributed system, the embodiment of this application provides the following flow control schemes that can control the flow of the distributed system:

[0025] Flow control scheme A1: The dynamic quota flow control scheme is used to control the flow of the distributed system. The dynamic quota...

Abstract

Embodiments of the present application provide a flow control method, a distributed system, equipment, and a storage medium. In the embodiment of this application, the dynamic quota flow control scheme and the PID flow control scheme are combined, that is, when the flow is not in a relatively stable state, the dynamic quota flow control scheme can effectively suppress the flow overshoot phenomenon, and also It can shorten the time for the subsequent PID flow control process to enter a steady state; when the traffic is in a relatively stable state, the PID flow control scheme can quickly respond to changes in distributed service nodes and load changes in a timely manner, increasing the number of users use experience.

Description

technical field [0001] The present application relates to the field of network technologies, and in particular to a flow control method, a distributed system, equipment and a storage medium. Background technique [0002] With the development of cloud computing, there are more and more cloud computing resources such as various elastic computing services and container services. These cloud computing resources also need to store data, so cloud storage systems appear. A cloud storage system is a distributed storage system that supports multiple users, allowing each user to store data on multiple service nodes or machines. [0003] In order to ensure the availability of the cloud storage system, it is necessary to limit the access traffic initiated by each user to the cloud storage system within the expected quota of each user. However, the number of service nodes that provide storage services for each user in the cloud storage system may vary, and the number of requests that ea...
