In this thesis, we study different Internet pricing schemes and how they can be applied to a multiple ISP environment. We first take a look at the current Internet architecture. Then the different classes that make up the Internet hierarchy are discussed. We also take a look at peering among Internet Service Providers (ISPs) and when it is a good idea for an ISP to consider peering. Moreover, advantages and disadvantages of peering are discussed along with speculations of the evolution of the Internet peering ecosystem. We then consider different pricing schemes that have been proposed and study the factors that make up a good pricing plan. Finally, we apply some game theoretical concepts to discuss how different ISPs could interact together. We choose a pricing model based on a Stackelberg game that takes into consideration the effect of the traffic variation among different customers in a multiple ISP environment. It allows customers to specify their desired QoS in terms of maximum allowable end-to-end delay. Customers only pay for the portion of traffic that meet this delay bound. Moreover, we show the effectiveness of adopting this model through a comparison with a model that does not take traffic variation into account. We also develop a naïve case and compare it to our more sophisticated approach.

The following study about the economic performance of the Johannesburg’s small Internet service providers investigates the economic performance of the small Internet providers against the backdrop of regulatory conditions. The study departs from the view point that reports about previous studies have not given particular attention to the economic performance of the small Internet service providers and other impacting factors. The study employed the qualitative research approach with an aim of obtaining deeper understanding and internal view as reiterated by the respondents. The analysis presented follows a guide by Neuman (2006) which departs from the premises of themes or concepts. The results of this study provide a perspective of respondents and the conclusions drawn by the researcher. The study ends by providing suggestions and recommendations for future studies. Suggestions and recommendations provided at the end have been prompted by the results and experiences encountered during the study. / M.A. (Communication Science)
