摘 要
随着信息技术的迅猛发展，网络环境日益复杂多变，网络故障成为影响数据库性能的重要因素。本研究旨在深入分析网络故障对数据库性能的影响并提出优化策略。通过构建模拟网络故障环境，采用多种网络故障类型如丢包、延迟等，选取具有代表性的数据库系统为研究对象，运用性能测试工具获取大量数据样本，从响应时间、吞吐量等方面量化评估网络故障对数据库性能的具体影响。研究发现，不同类型的网络故障对数据库性能的影响存在显著差异，其中丢包率与延迟对数据库性能呈现非线性负相关关系，且在高并发场景下影响更为明显。基于此，提出一种综合考虑网络状态感知与数据库自适应调整的优化方法，该方法能够根据实时网络状况动态调整数据库参数配置，有效缓解网络故障带来的负面影响。

Abstract
With the rapid development of information technology, the network environment is increasingly complex and changeable, and the network failure has become an important factor affecting the database performance. This study aims to deeply analyze the impact of network failures on database performance and propose an optimization strategy. By constructing the simulated network fault environment, using a variety of network fault types such as packet loss, delay, etc., the representative database system is selected as the research ob ject, and the performance test tools are used to obtain a large number of data samples, and the specific impact of the network fault on the database performance is quantitatively evaluated from the aspects of response time and throughput. It is found that different types of network failures affect database performance are significantly different, in which the packet loss rate shows a non-linear negative correlation with delay on database performance, and the influence is more obvious in high concurrency scenarios. Based on this, an optimization method that comprehensively considers the network state perception and database adaptive adjustment is proposed. This method can dynamically adjust the database parameter configuration according to the real-time network condition, and effectively alleviate the negative effects caused by network failure.
