In this paper, the authors study the interaction patterns among traffic from different application classes, namely, how they collaboratively form a mixed traffic activity graph (mixed TAG). Utilizing real traffic traces from a major ISP and a large university network, they show that densely connected sub-graphs or clusters are the building blocks for a mixed TAG. These sub-graphs can be either dependent or independent for different application classes. In addition, clusters from different application classes exhibit repulsive/attractive relationships while they interconnect to form a mixed TAG.
