Aiming to address the problem of information loss in traffic representation for network anomaly detection

the impact of feature information dimension of different traffic representation on anomaly detection performance was analyzed from the perspective of data collection granularity. Firstly

the integrated collaboration between traffic representation granularity and the coupling among traffic representation

feature learning

and detection in malicious anomaly detection was introduced. Subsequently

the evolution of traffic representation in network anomaly detection was systematically reviewed

providing a comprehensive analysis of its forms

feature learning

and application in anomaly detection both globally and domestically. Finally

the future research directions revolving around the collaborative development trend of traffic representation in network anomaly detection were outlined.
