The invention relates to the technical field of data communication, and discloses a network flow
deep packet inspection multi-task classification method and
system, and the method comprises the steps: firstly obtaining a target network flow data flow, recognizing the corresponding protocol and load content of the target network flow data flow, and generating a flow
topological graph related to the target network flow data flow and the load content; collecting a topological data sequence in the atlas, analyzing a corresponding
data transmission type, analyzing a type guiding mode, and fitting a flow
transmission curve; identifying an abnormal traffic
peak value and a core transmission hotspot in the curve, calculating a traffic
throughput threshold and analyzing a network cache state; then, a deep
packet detection framework is constructed based on the cache state, a
processing delay value and a classification misjudgment rate of a real-time classification path in the framework are collected, and a traffic coordination index is calculated; and finally, reconstructing a data coordination task according to the index, identifying a task classification protocol, and generating a multi-task-oriented
classification result of the flow data flow. According to the invention, the detection and classification efficiency of multi-task traffic in a
complex network environment can be improved.
