Embodiment 1
[0055] see figure 1 , figure 1 It is a flow chart of Embodiment 1 of the method for identifying abnormal flows in the entire network based on the distribution of traffic characteristics in the present invention, as shown in figure 1 As shown, the method includes:
[0056] Step S1, conduct coarse-grained anomaly identification on the network data flow in the entire network, extract node pairs with abnormal traffic from the entire network, and determine the characteristic category of the abnormal traffic.
[0057] The entire network of an ISP (Internet Service Provider, Internet Service Provider) includes the backbone network and the LAN connected to the backbone network. The network range is large and there is a lot of traffic data. If you want to directly identify abnormal traffic and determine the characteristics of the abnormal traffic value, the amount of data to be collected will be very large, and how to identify abnormal traffic and characteristic values of abnormal ...
