Application layer traffic speed limiting method, terminal equipment and storage medium

Abstract

The invention relates to an application layer traffic speed limiting method, terminal equipment and a storage medium. The method comprises the following steps: S1, receiving an input file stream; S2,initializing and setting a flow application proportion ratio ratio to be equal to 0.1 and a residual flow bandWidth to be equal to a maximum bandwidth MAX_BANDWIDTH; S3, applying rate*bandWidth tokensto the traffic speed limiting system, and if the application fails, entering S4; and if the application succeeds, entering S5; S4, according to the request number of the current flow speed limiting system and the residual flow of the flow speed limiting system returned when the application fails, resetting a flow application ratio ratio ratio ratio=1/the request number of the current flow speed limiting system and a residual flow bandWidth=the residual flow of the flow speed limiting system, and returning to S3; S5, writing a file stream with the size of ratio*bandWidth*k into the network stream, wherein k represents a bandwidth corresponding to one token; and S6, judging whether the file is read or not, and if so, ending; otherwise, entering S3. Flow passing through the flow speed limiting system can be intercepted and then flows to the network, the speed limiting function is achieved, and network storm is avoided.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to an application layer traffic rate limiting method, terminal equipment and a storage medium. Background technique [0002] Common traffic limiting is mostly applied to network physical devices (such as routers, interactive machines), host network cards, and Nginx rate limiting modules at the application layer. Limiting traffic on network physical devices has the following problems: (1) The configuration of network physical devices cannot be easily modified, which will affect all applications on the network; (2) The business environment cannot modify the user network environment; (3) The application layer controls network physical devices You need to consider the device, model, driver and other issues. There are the following problems with current limiting at the host network card level: (1) It can only limit the traffic of a single host, but cannot protect the enti...

Limiting traffic on network physical devices has the following problems: (1) The configuration of network physical devices cannot be easily modified, which will affect all applications on the network; (2) The business environment cannot modify the user network environment; (3) The application layer controls network physical devices Need to consider equipment, model, driver and other issues

There are the following problems with current limiting at the host network card level: (1) It can only limit the traffic of a single host, but cannot protect the entire bandwidth; (2) Distributed and cluster environments may involve a large number of hosts, and the configuration of each host is unreasonable, which wastes human resources , inconvenient to manage; (3) affect other applications on the host

However, the Nginx speed limit module has the following problems: the Nginx speed limit module supports two modes to limit the number of connections and limit the request rate, but cannot directly limit the size of the request traffic, and the request may occupy a large amount of bandwidth, which cannot avoid network storms
