Introduction

Nowadays, the Internet is becoming more and more complex due to an ever-increasing number of network devices, various multimedia services, and a prevalence of encrypted traffic.

Therefore, in this context, this book presents a novel efficient multi-modular troubleshooting architecture to overcome limitations related to encrypted traffic and high time complexity. This architecture contains five main modules: data collection, anomaly detection, temporary remediation, root cause analysis, and definitive remediation.

In data collection, there are two sub-modules: parameter measurement and traffic classification. This architecture is implemented and validated in a software-defined networking (SDN) environment.
