This paper is concerned with the issue of side payments between Content Providers (CPs) and Internet Service (access bandwidth) Providers (ISPs) in an Internet that is potentially not neutral. The authors herein generalize past results modeling the ISP and CP interaction as a non-cooperative game in two directions. They consider different demand response models (price sensitivities) for different provider types in order to explore when side payments are profitable to the ISP. Also, they consider convex (non-linear) demand response to model demand triggered by traffic which is sensitive to access bandwidth congestion, particularly delay-sensitive interactive real-time applications.
