Data flow link determination method, apparatus and device, and computer storage medium

The invention discloses a data flow link determination method, device and equipment and a computer storage medium, and the method comprises the steps: obtaining data and data communication information, the data communication information comprises a data source IP, a destination IP, communication time, communication frequency between IP addresses, and frequency of returning data from the destination IP to the source IP; a knowledge graph is constructed based on the obtained data, the communication frequency between the IP addresses and the frequency of data returned from the destination IP to the source IP, nodes of the knowledge graph represent the IP addresses, and edges between the nodes represent the communication relation between the IP addresses; determining the weight of the node in the knowledge graph based on the communication time, the communication frequency between the IP addresses, the frequency of returning data from the destination IP to the source IP and the initial access probability transmitt
