Abstract

The dynamic behavior of software systems attracts widened attention through the phenomenon of software aging. Software aging is caused by runtime environment deterioration, such as the gradual loss of memory or CPU cycles. The dynamic behavior of aged software systems can be described by a set of evolving resource variables, including CPU usage, I/O bandwidth, available memory and the like. From this point of view, an aging software system can be analogous to a dynamic system. Control theory provides sound and rigorous mathematical principles to analyze dynamic systems and build controllers for them. This paper introduces control theory to analyze and build a control model and apply control techniques to an aged web server. First, we treated the software system as a black box, and conducted controlled experiments to build the relationship between input and output. Then, these input-output couples are used to build a control model via a system identification method. Finally, a PI (proportional-integral) controller is designed to adjust the aged state of the software system, and software rejuvenation techniques are customized to target the web server. Performance testing shows that our approach can accurately track the reference value set by the website administrator.

一种防止软件老化导致系统资源耗尽的反馈控制方法

软件系统的动态行为通过软件老化现象引起了广泛的关注。软件老化是由运行时环境恶化引起的，例如内存逐渐丢失或CPU周期逐渐减少。老化软件系统的动态行为可以用一组不断变化的资源变量来描述，包括CPU使用率、I/O带宽、可用内存等。从这个角度来看，一个老化的软件系统可以类似于一个动态系统。控制理论为分析动态系统和为其建立控制器提供了健全和严格的数学原理。本文介绍了控制理论，分析并建立了控制模型，并将控制技术应用于一个老旧的web服务器。首先，我们将软件系统视为一个黑盒子，并进行控制实验来建立输入和输出之间的关系。然后，利用这些输入输出对，通过系统辨识方法建立控制模型。最后，设计了PI(比例积分)控制器来调整软件系统的老化状态，并针对web服务器定制了软件再生技术。性能测试表明，我们的方法可以准确地跟踪网站管理员设置的参考值。
