Alternative revenue sources for Internet service providers

The Internet has evolved from a small research network towards a large globally interconnected network. The deregulation of the Internet attracted commercial entities to provide various network and application services for profit. While Internet Service Providers (ISPs) offer network connectivity services, Content Service Providers (CSPs) offer online contents and application services. Further, the ISPs that provide transit services to other ISPs and CSPs are known as transit ISPs. The ISPs that provide Internet connections to end users are known as access ISPs. Though without a central regulatory body for governing, the Internet is growing through complex economic cooperation between service providers that also compete with each other for revenues. Currently, CSPs derive high revenues from online advertising that increase with content popularity. On other hand, ISPs face low transit revenues, caused by persistent declines in per-unit traffic prices, and rising network costs fueled by increasing traffic volumes. In this thesis, we analyze various approaches by ISPs for sustaining their network infrastructures by earning extra revenues. First, we study the economics of traffic attraction by ISPs to boost transit revenues. This study demonstrates that traffic attraction and reaction to it redistribute traffic on links between Autonomous Systems (ASes) and create camps of winning, losing and neutral ASes with respect to changes in transit payments. Despite various countermeasures by losing ASes, the traffic attraction remains effective unless ASes from the winning camp cooperate with the losing ASes. While our study shows that traffic attraction has a solid potential to increase revenues for transit ISPs, this source of revenues might have negative reputation and legal consequences for the ISPs. Next, we look at hosting as an alternative source of revenues and examine hosting of online contents by transit ISPs. Using real Internet-scale measurements, this work reports a pervasive trend of content hosting throughout the transit hierarchy, validating the hosting as a prominent source of revenues for transit ISPs. In our final work, we consider a model where access ISPs derive extra revenues from online advertisements (ads). Our analysis demonstrates that the ad-based revenue model opens a significant revenue potential for access ISPs, suggesting its economic viability.This work has been supported by IMDEA Networks Institute.Programa Oficial de Doctorado en Ingeniería TelemáticaPresidente: Jordi Domingo-Pascual.- Vocal: Víctor López Álvarez.-Secretario: Alberto García Martíne

A Study of Non-Neutral Networks with Usage-based Prices

Hahn and Wallsten wrote that network neutrality "usually means that broadband service providers charge consumers only once for Internet access, do not favor one content provider over another, and do not charge content providers for sending information over broadband lines to end users." In this paper we study the implications of non-neutral behaviors under a simple model of linear demand-response to usage-based prices. We take into account advertising revenues and consider both cooperative and non-cooperative scenarios. In particular, we model the impact of side-payments between service and content providers. We also consider the effect of service discrimination by access providers, as well as an extension of our model to non-monopolistic content providers

Economic Impacts of GO TO 2040

The economy of the Chicago metropolitan region has reached a critical juncture. On the one hand, Chicagoland is currently a highly successful global region with extraordinary assets and outputs. The region successfully made the transition in the 1980s and 1990s from a primarily industrial to a knowledge and service-based economy. It has high levels of human capital, with strong concentrations in information-sector industries and knowledge-based functional clusters -- a headquarters region with thriving finance, business services, law, IT and emerging bioscience, advanced manufacturing and similar high-growth sectors. It combines multiple deep areas of specialization, providing the resilience that comes from economic diversity. It is home to the abundant quality-of-life amenities that flow from business and household prosperity.On the other hand, beneath this static portrait of our strengths lie disturbing signs of a potential loss of momentum. Trends in the last decade reveal slowing rates, compared to other regions, of growth in productivity and gross metropolitan product. Trends in innovation, new firm creation and employment are comparably lagging. The region also faces emerging challenges with respect to both spatial efficiency and governance.In this context, the Chicago Metropolitan Agency for Planning (CMAP) has just released GO TO 2040, its comprehensive, long-term plan for the Chicago metropolitan area. The plan contains recommendations aimed at shaping a wide range of regional characteristics over the next 30 years, during which time more than 2 million new residents are anticipated. Among the chief goals of GO TO 2040 are increasing the region's long-term economic prosperity, sustaining a high quality of life for the region's current and future residents and making the most effective use of public investments. To this end, the plan addresses a broad scope of interrelated issues which, in aggregate, will shape the long-term physical, economic, institutional and social character of the region.This report by RW Ventures, LLC is an independent assessment of the plan from a purely economic perspective, addressing the impacts that GO TO 2040's recommendations can be expected to have on the future of the regional economy. The assessment begins by describing how implementation of GO TO 2040's recommendations would affect the economic landscape of the region; reviews economic research and practice about the factors that influence regional economic growth; and, given both of these, articulates and illustrates the likely economic impacts that will flow from implementation of the plan. In the course of reviewing the economic implications of the plan, the assessment also provides recommendations of further steps, as the plan is implemented, for increasing its positive impact on economic growth

Impact of prefix hijacking on payments of providers

Abstract—Whereas prefix hijacking is usually examined from security perspectives, this paper looks at it from a novel economic angle. Our study stems from an observation that a transit AS (Autonomous System) has a financial interest in attracting extra traffic to the links with its customers. Based on real data about the actual hijacking incident in the Internet, we conduct simulations in the real AS-level Internet topology with synthetic demands for the hijacked traffic. Then, we measure traffic on all inter-AS links and compute the payments of all providers. The analysis of our results from technical, business, and legal viewpoints suggests that hijacking-based traffic attraction is a viable strategy that can create a fertile ground for tussles between providers. In particular, giant top-tier providers appear to have the strongest financial incentives to hijack popular prefixes and then deliver the intercepted traffic to the proper destinations. We also discuss directions for future research in the area of hijacking-based traffic attraction

Understanding incentives for prefix aggregation in BGP

Proceeding of: ReArch'09, Proceedings of the 2009 workshop on Re-architecting the internet, (49-54), 1 December 2009, Rome, Italy.Over the last few years, a significant amount of the effort of the Future Internet architecture is devoted in order to improve the scalability of the next generation routing architecture. In this paper, we study providers’ incentives to perform prefix aggregation or deaggregation of non-customers routes. This is essentially a tradeoff between reduced router memory and reduced capacity of attracting customer traffic. We study the case where two ISPs compete for attracting traffic, by using game theory. In particular, we propose a game-theoretic model and we analyze the properties of the equilibrium. In a symmetric case, if a single Autonomous System (AS) is found to be deaggregating a given prefix, then all others will have the incentive to do the same, even if they end up with lower benefits. We find that pure equilibria do not always exist and we derive the conditions based on two model parameters. These findings suggest that BGP instability can be a common problem in a competitive scenario.European Community's Seventh Framework ProgramPublicad

Modeling tourist movements - A local destination analysis

Models depicting the spatial movement patterns of tourists within a destination are proposed in this paper. The models are developed using an inductive approach based on urban transportation modeling and tourist behavior, to identify explanatory factors that could influence movements. Factors identified included a set of destination characteristics and a set of tourist characteristics that influence decision making and behavior. These factors influence movement patterns in two ways, resulting in four types of territorial models and three linear path models. Understanding the movement of tourists within a destination has practical applications for destination management, product development and attraction marketing
