Multi-dimensional service flow limiting method and system based on shared memories among containers

Abstract

The embodiment of the invention provides a multi-dimensional service flow limiting method and system based on an inter-container shared memory. The method comprises the steps that for a plurality of application processes on the same server, a flow limiting counting file is mapped into a virtual address space of the application processes through the MMAP technology, and for any application process,three dimensions of the application process are selected for flow limiting according to the type of the application process. According to the multi-dimensional service flow limiting method and systembased on the shared memory between the containers, the problem that a traditional flow limiting method cannot cross service containers is solved, the performance problem caused by the fact that a common distributed flow limiting algorithm accesses three-party middleware is solved, and good balance is achieved between the traditional flow limiting method and the three-party middleware.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular to a method and system for multi-dimensional service current limiting based on shared memory among containers. Background technique [0002] In a high-concurrency real-time trading system, when the request traffic of a certain service suddenly surges and influxes continuously, a series of problems such as high service load and network response delay will occur, and a chain reaction may occur, triggering an avalanche, causing other A service is unavailable which, if not addressed, could render the entire system unavailable. [0003] Therefore, it is very important to control the traffic in the service. The high availability and stability of the service can be guaranteed through reasonable restrictions on the traffic. [0004] The classic current limiting algorithm proposed based on the current limiting problem solves the impact of unexpected burst tra...

Problems solved by technology

[0004] The classic current limiting algorithm proposed based on the current limiting problem solves the impact of unexpected burst traffic on the system, but these algorithms can only limit the current within a single process, and now typical Internet systems are built on Based on micro-service and container technology, the traditional current limiting algorithm cannot meet the requirements of cross-process or even cross-service container current limiting
