Method and system for guaranteeing application service quality in distributed environment

Abstract

The invention provides a method and a system for positioning bottleneck nodes and ensuring application service quality in the distributed environment. The method for positioning a bottleneck node comprises the following steps: calculating a delay fluctuation value of each node in a processing stage on a critical path of service; determining the bottleneck node according to the delay fluctuation value. The service critical path is obtained by processing the critical path of service request in a period of time; the delay fluctuation value is obtained according to time of processing the request of the node in the processing period in a period of time. A method for ensuring application service quality comprises the following steps: positioning a bottleneck node according to the service with long tail delay; checking whether the delay fluctuation value of the bottleneck node exceeds a predefined threshold or not, and carrying out fault diagnosis according to checking result or carrying out the request for regulating speed or accelerating speed of service request of the bottleneck node. According to the method and the system for positioning bottleneck nodes and ensuring application service quality in the distributed environment, the request response time fluctuation is reduced; the long tail delay is reduced; in addition, the cost for optimizing the nodes one by one and step by step is also reduced.

Description

technical field [0001] The present invention relates to the technical field of distributed computing, and more specifically, to a method and system for locating bottleneck nodes and guaranteeing application service quality in a distributed environment. Background technique [0002] Currently, Internet applications such as e-mail, search, online shopping, social networking, online video, and network maps have become a part of people's lives. These applications often serve hundreds of millions of users, which means that Internet applications have become social public services like electricity, and various distributed computing environments that support Internet applications with a large number of users have also become social core infrastructure like power plants . [0003] In a distributed environment, generally, Internet applications are divided into many service nodes (or service modules) for step-by-step processing, and these service modules are deployed on multiple serve...

However, this method will dynamically adjust the priority of each node on the request delivery path, and is only applicable to the dependent / serial mode. When applied to the division / aggregation mode, there will be relatively large overhead
