2 The Concept of Group Behavior

The results of the literature [8] show that more than 98% of IP addresses are no more than 1 km in physical distance for the same C network segment. The survey results about the IP address distribution based on the campus network of Xi’an Jiao Tong University show that the IP address in the same C network segment is distributed in the same dormitory building, that is to say the physical distance is very close. Also the students from the same school are often in the same dormitory, which shows the network users in the same C network segment have the same network requirements, which also provide a reasonable explanation for splitting users in to the group flow model according to the C network segment.

Figure 1 presents the definition of group behavior flow, according to the monitoring location the network are divided into two parts, the internal monitoring network and external network, the internal monitoring network is the network need to be monitored, which is the campus network of Xi’an Jiao Tong University, the external network is the external Internet which composed by the monitoring network communicate with. The network topology can be described by the logical links formed between groups, then the monitoring of network abnormal behaviors can be implemented according to the network traffic distribution on the logical topology. The paper only focuses on the communication between internal network and external network, and the change of the interaction behavior between the internal users and external network.
