    Summary

    The importance of the Internet in economic and social areas has been growing strongly in the recent past. Since economic and social aspects did not play a role when the Internet was developed in the 70s, today’s Internet reaches its limits because of unpredictable problems and conflicts of interest between network and service providers. An example is the cost effective traffic routing between network providers, which can lead to quality degradations in the delivery of multimedia content. Based on primer orthogonal approaches as "Economic Traffic Management" and "Design for Tussle", these economic aspects are systematically taken into account to design and evaluate Internet mechanisms. A collection of existing and future Internet mechanisms is deployed, which shows the impact of economic aspects and the underlying paradigms. It makes fundamental understanding for design and evaluation of technical mechanisms and analysis of economic factors possible. These factors are demonstrated by two spanning case studies. In the first case appropriate routing mechanisms for so called Content Distribution Networks (CDNs) are developed and evaluated. In the second case energy efficient mechanisms for video-streaming in distributed overlay networks are designed and evaluated. In an iterative process the findings of both cases influence the abstract, systematic point of view and vice versa. This process ends in the fusion of the developed mechanisms.
