These data are processed and expanded with feature engineering in order to create a training set. A simulated network is created to collect data related to the performance of the network links on every interface. In this paper, we present a solution to predict the bandwidth utilization between different network links with a very high accuracy. Predicting the bandwidth utilization on network links can be extremely useful for detecting congestion in order to correct them before they occur. By comprehensively surveying different approaches toward FGTA, we introduce their input traffic data, elaborate on their operating principles by different use cases, indicate their limitations and countermeasures, and raise several promising future research avenues. To help scholars and developers research and advance this technology, in this report, we examine the literature that deals with FGTA, investigating the frontier developments in this domain. It plays a critical role in intrusion and anomaly detection, quality of experience investigation, user activity inference, website fingerprinting, location estimation, etc. Nowadays, with the increasingly complex Internet architecture, the increasingly frequent transmission of user data, and the widespread use of traffic encryption, FGTA is becoming an essential tool for both network administrators and attackers to gain different levels of visibility over the network. Different from traditional TA, FGTA approaches are usually based on machine learning or high-dimensional clustering, enabling them to discover subtle differences between different network traffic sets. Fine-grained traffic analysis (FGTA), as an advanced form of traffic analysis (TA), aims to analyze network traffic to deduce information related to application-layer activities, fine-grained user behaviors, or traffic content, even in the presence of traffic encryption or traffic obfuscation.
