Interconnection Among ISPs in a Competitive Environment
In this talk we will present our current research about a network formation game among a set of Internet Service Providers (ISPs) that interconnect to transport IP traffic across a set cities. The research includes: (i) the definition and study of a non-cooperative game among ISPs facing exogenous demand for the transport of traffic; ii) the computational simulation of the ISPs behavior as a way to find the set of Nash Equilibrium of this game; (iii) the analysis of equilibrium networks in terms of topology, cost and industry structure; (iv) the design of interconnection incentives aimed at reducing provisioning costs. This talk will focus primarily on the definition of the network formation game and on the main theoretical findings obtained so far about its properties. Challenges faced while trying to simulate such a game will be briefly discussed, along with the approaches used. Finally, orientations and ideas for future work will be outlined.
