网络功能虚拟化通过使用虚拟化环境为网络管理引入了额外的复杂性。管理的数据量和操作复杂性增加，这使得服务保证和故障恢复更难实现。为了应对这一挑战，本文提出了一种分布式管理功能，称为虚拟化网络管理功能（vNMF），以检测与虚拟化服务相关的故障。vNMF通过监视使用自组织映射算法处理的物理层统计信息来检测故障。实验结果表明，该算法能够成功检测出内存泄漏和网络拥塞故障，且故障检测的准确率较普通k-means聚类有显著提高。
Network function virtualization introduces additional complexity for network management through the use of virtualization environments. The amount of managed data and the operational complexity increases, which makes service assurance and failure recovery harder to realize. In response to this challenge, the paper proposes a distributed management function, called virtualized network management function (vNMF), to detect failures related to virtualized services. vNMF detects the failures by monitoring physical-layer statistics that are processed with a self-organizing map algorithm. Experimental results show that memory leaks and network congestion failures can be successfully detected and that and the accuracy of failure detection can be significantly improved compared to common k-means clustering.
