Modeling Internet Backbone Traffic Based on Multi-Commodity Flow

Abstract

Network traffic is the key factor to describe the adaptive business of Internet. As Internet becomes key battlefield of cyber warfare, how to model the Internet traffic at the macro level has become a hot research topic in war simulation and cyber warfare. Focusing on the global undersea cable system which serves as the backbone of the Internet, this paper proposes an Internet traffic modeling method based on multi-commodity flow. This method can estimate the traffic demand between each pair of regions, generate traffic flow distribution in global undersea cable system, and support adaptive adjustment of Internet traffic according to damage situation of undersea cable system in a crisis. Finally, the method is validated by an example.
