摘 要
随着信息技术的迅猛发展，网络工程在现代信息社会中扮演着至关重要的角色，然而网络故障不可避免，这促使容错与冗余技术成为保障网络稳定可靠运行的关键。本研究旨在深入探讨网络工程中的容错与冗余技术，以提高网络系统的可靠性、可用性和安全性。通过文献综述与理论分析相结合的方法，梳理现有容错与冗余技术的原理、分类及应用场景，并基于此构建一种融合多种技术优势的新模型。该模型不仅综合考虑了硬件层面如服务器集群、路由设备等的冗余配置，还涵盖了软件层面包括数据备份、错误检测与纠正算法等机制，在此基础上进行仿真实验验证其有效性。实验结果表明，所提模型在网络出现局部故障时能够快速切换至备用路径或组件，确保业务连续性，且对网络性能影响较小。

Abstract
With the rapid development of information technology, network engineering plays a vital role in the modern information society, but the network failure is inevitable, which makes fault tolerance and redundancy technology become the key to ensure the stable and reliable operation of the network. This study aims to deeply explore the fault tolerance and redundancy techniques in network engineering to improve the reliability, usability and security of network systems. Through the combination of literature review and theoretical analysis, the principle, classification and application scenarios of existing fault-tolerant and redundancy technologies are summarized, and a new model integrating multiple technical advantages is constructed based on this. The model not only comprehensively considers the redundant configuration of hardware level such as server cluster and routing equipment, but also covers the software level mechanisms including data backup, error detection and correction algorithm. On this basis, simulation experiments are conducted to verify its effectiveness. The experimental results show that the proposed model can quickly switch to the standby path or component when the network has a local failure, ensuring business continuity and having little impact on the network performance.
