Exploring collective behaviors with short-range correlation between routers

Existing approaches on Internet dynamics pay more attention to the user or session behaviors, but lack an overall outlook on a system level. This paper focuses on the correlation widely existing in the network and the impact on the dynamical collective behaviors of Internet. Our simulations show that phase transition happens when the short-range interactions between two neighbor routers bring the system into a critical state. We illustrate how the Internet coordinates by self-tuning and maintain this most efficient state which can be got dynamically.
