Embodiment approach
[0060] 1. Abstraction and modeling of traffic communication relationship based on graph coloring
[0061] 1.1 Traffic information preprocessing
[0062] Read and analyze the captured traffic files, and record the source, destination IP and timestamp of each data packet. After deduplicating the source and destination IP addresses of all real traffic, the following definition set is obtained:
[0063] R_IP={r_ip 1 , r_ip 2 , r_ip 3 ,...,r_ip a |a>=2}
[0064] The real traffic collection point is the set of router interfaces:
[0065] I = {r_interface 1 ,r_interface 2 ,r_interface 3 ...,r_interface n |n>=1, and n is unknown}
[0066] then r_ip 1 , r_ip 2 , r_ip 3 ,...,r_ip a is all IP addresses that appear in the traffic captured by the interface in I.
[0067] Take real.pcap, a data packet to be played back, as an example. After this processing, a set containing 8 IP addresses is obtained. R_IP = {37.252.244.2, 208.111.148.6, 123.54.180.8, 128.185.235.10, ...}. ...
