Abstract
Our study in the previous chapter showed the technical feasibility of dynamic fast-lane and slow-lane creation driven by content providers (CPs), using software defined networking (SDN) platforms. However, today’s residential broadband ecosystem is in stasis—Internet Service Providers (ISPs) suffer from low margins and flat revenues, CPs have unclear incentives to invest in broadband infrastructure, and users have limited dimensions (speed/quota) in which to compare broadband pricing. In this chapter, we focus on the economic dimension of service quality offerings, in the form of fast- and slow-lanes, for overcoming this stasis. We propose an architecture in which all entities have a say—CPs request dynamic fast/slow-lane creation for specific sessions, ISPs operate and charge for these lanes, and users control their broadband bandwidth available to such lanes. We develop an economic model that balances fast/slow-lane pricing by the ISP with the returns for CPs and service quality improvement for users, and evaluate the parameters of our model with real traffic traces. We believe our proposal based on dynamic fast- and slow-lanes can represent a win-win-win situation for ISPs, CPs, and users alike, and has the potential to overcome the current stagnation in broadband infrastructure investment.
