This chapter reviews core concepts of peer-to-peer (P2P) networking. It highlights the management of resources, such as bandwidth, storage, information, files, and processor cycles based on P2P networks. A model differentiating P2P infrastructures, P2P applications, and P2P communities is introduced. This model provides a better understanding of the(More)
The future of networking will be shaped by open, heterogeneous and complex structures, consisting of many independent information systems, which may cooperate with other systems if advantageous, but usually work in an autonomous, self-interested and not necessarily cooperative way. In this article, we propose a novel approach for information system design(More)

This paper contributes to the ongoing stream of research correlating social network structure with individual and organizational performance. While teaching a course on optimizing online communication behavior and social network analysis, we collected preliminary data on the relationship between dynamic social network structures and individual and team(More)
Historical examples (ISDN, Teletex, telefax, telex) show us that forecasting efforts in the telecommunication sector can go awry – not only by a few percentage points but by large magnitudes. We maintain that with strong network effects it is not possible to forecast the success of telecommunication services with a high degree of confidence. This paper(More)
