Intelligent gateway dynamic flow limiting implementation method

Abstract

The invention discloses an intelligent gateway dynamic flow limiting implementation method, which comprises the following steps of: starting an intelligent gateway, receiving a service request, caching configuration information of the intelligent gateway and loading the configuration information into a memory; refreshing the memory cache automatically, and meanwhile recalculating the cache expiration time; reading configuration information; performing black and white list verification, performing login verification and permission verification, and if login succeeds, obtaining a request body rewriting mapping rule from the long-term cache, and executing request body rewriting; performing intelligent gateway distributed cluster flow limiting control, configuring the local flow limiting size of the gateway, and when the flow is too large, returning a flow limiting response code; performing local fusing control; and forwarding the service request to the intelligent gateway cluster, and processing the request to realize load balancing. According to the invention, the deployment architecture is simple, the database and the gateway are decoupled, personalized dynamic current limiting and fusing are realized, an intelligent gateway realization method with distributed deployment, high availability and high concurrency capability is provided, the error-tolerant rate of communication abnormity is increased, and the use scene is expanded.

Description

technical field [0001] The content of the present invention relates to the technical field of gateways, in particular to a method for realizing dynamic current limiting of an intelligent gateway. Background technique [0002] With the development of the Internet, network access traffic is increasing, and the requirements for service stability and availability are getting higher and higher. High availability has become an important criterion for measuring the performance of a service. [0003] The gateway is usually used as a unified entrance and exit of the API, and at the same time provides functions such as load balancing, service degradation, current limiting, and circuit breaker. Although the existence of these functions can reduce the risk of back-end service downtime, and can return fixed content when the back-end service is down, these functions cannot guarantee to continue to provide stable and accurate output after the back-end service is down, seriously reducing th...
