Private peering,transit and traffic diversion

Private peering refers to settlement-free connectivity agreements between Internet Service Providers meant to interconnect their networks by-passing congested National Access Points. We explore the incentives for bilateral peering with particular emphasis on traffic diversion. A private peering agreement between two providers improves the quality of both and would divert traffic from third parties. This provides an incentive for peering. A three-player model is introduced and analyzed. Complication introduced by price competition and heterogeneous consumers are also studied.
