复杂的传统网络结构限制了网络功能的发展,也逐渐暴露传统故障诊断算法的缺点。为此本文从新型网络环境的角度详细分析软件定义网络(software-defined networking, SDN)架构中故障诊断技术的发展过程,并从诊断方式对比其与传统网络的不同。本文介绍了SDN的架构、网络虚拟化的定义以及系统监控方法;针对SDN中不同故障诊断算法的差异以及虚拟环境中的故障诊断问题,总结了新型故障诊断技术,依据不同的算法原理归纳了5类故障诊断方法,并对不同类型的方法进行了优缺点比较。算法比较结果表明:在性能方面,结合新型网络结构的故障诊断算法在拓扑发现、数据收集、诊断速度以及算法设计的灵活性方面更加适应现代网络的发展;在架构方面,SDN在物理、逻辑和虚拟3个层面都有创新性故障诊断算法,并在传统网络的基础上增加了网络的稳健性和可靠性;最后从5个方面进行未来展望,为后续故障诊断技术优化研究提供参考。

Traditional network structure is complicated, which limits the development of network functions. And gradually, it also exposes the shortcomings of traditional fault diagnosis algorithms. To solve this problem, this paper analyzes the development process of fault diagnosis technology in the software-defined networking (SDN) architecture in detail, and analyzes its difference from traditional network from the perspective of diagnosis mode. Firstly, the architecture of SDN, the definition of network virtualization and system monitoring methods are introduced. Then, aiming at the differences of different fault diagnosis algorithms in SDN and the problem of fault diagnosis in a virtual environment, this paper summarizes the new fault diagnosis technologies. Five types of fault diagnosis methods are summarized based on different principles of the algorithm, and the advantages and disadvantages of different types of methods are compared. Finally, this paper looks forward to the future from five aspects, which provides reference for the follow-up optimization research of fault diagnosis technology.
