Network access flow limiting control method and device and computer readable storage medium

Abstract

The embodiment of the invention discloses a flow limiting control method and device for network access and a computer readable storage medium. The method comprises the steps of when a service access request sent by a user is received and the current access is judged to be the first access, acquiring the accumulated page view of all service interfaces within a preset duration and the total number of access users; calculating access frequency according to the total number of the access users and the accumulated page view; calculating an expected page view according to the accumulated page view and the access frequency; if the expected page view exceeds a preset threshold, refusing the service access request; and if the expected page view does not exceed the preset threshold, responding to the service access request according to the service logic corresponding to the service access request. Based on the scheme, when a new request is received, the expected page view is estimated. When thepage view is judged to be close to the bottleneck of the system in advance, flow limiting is carried out, and part of new user access is refused to guarantee normal operation of the system. Users entering the system are not affected by flow limiting while flow limiting is achieved.

Description

technical field [0001] The present invention relates to the technical field, in particular to a network access current limiting control method, device and computer-readable storage medium. Background technique [0002] When a user terminal accesses the business system, in a business scenario where a large number of users are online and requests are concurrent, the server will bear enormous pressure. In order to prevent the server from being overwhelmed by sudden traffic, user access is usually limited. [0003] At present, the commonly used current limiting methods are as follows: counter method: within a certain time window, when the access volume exceeds the preset value, it will be restricted; token bucket: store tokens in the token bucket at a preset rate , when the capacity of the token bucket is exceeded, it will be discarded. When there is access, the token is taken from the token bucket and then the interface is allowed to access; the leaky bucket method: the request...

However, in some complex scenarios, this current limiting method will cause users to be unable to access the system normally. For example, for a medical service system, it is generally necessary to perform multiple interface interactions with the background to complete sequential medical services. In this case , if the interface is still limited according to the above scheme, users who have already entered the system will also encounter interface current limitation when users provide online medical services, and service interruption will occur, which will affect the user experience
