Internet-based informatics systems increasingly influence real-life situations. Competencies for Internet applications and services have to be explicitly attained because not observable processes and invisible structures have to be considered. There are examples of successful learning processes for selected parts of the Internet. A systematic analysis of educational requirements and a derived d...

Social networks that are built on top of the web, e.g., orkut [9], have been proliferating among online communities. We propose social internetworks, where essential functions of social networks are implemented on top of peer-to-peer networks. Participants and communities are connected through attribute queries and reputation queries; reputation queries are applied to attributes with Secure Eig...

The current deployment approach of the commercial Content Delivery Network (CDN) providers involves placing their Web server clusters in numerous geographical locations worldwide. However, the requirements for providing high quality service through global coverage might be an obstacle for new CDN providers, as well as affecting the commercial viability of existing ones. It is evident from the m...

The convergence of informatics systems and media systems has caused a lack of educational concepts for long-term knowledge. We assume that gaining informatics competencies enables adults to meet the demands of today’s society. Therefore, didactics of informatics has to contribute educational concepts. In this paper, we introduce a strategy to structure the domain Internetworking. Aim of our res...

Quantum networks build on entanglement and quantum measurement to bring new capabilities to communication systems. Quantum physical effects can be used to detect eavesdropping, to improve the shared sensitivity of separated astronomical instruments, or to create distributed states that will enable numerical quantum computation over a distance using teleportation. Because quantum data is fragile...

The Logistical Computing and Internetworking (LoCI) project is a reflection of the way that the next generation internetworking fundamentally changes our definition of high performance wide area computing. A key to achieving this aim is the development of middleware that can provide reliable, flexible, scalable, and cost-effective delivery of data with quality of service (QoS) guarantees to sup...

Online social networks (OSNs) contain data about users, their relations, interests and daily activities and the great value of this data results in ever growing popularity of OSNs. There are two types of OSNs data, semantic and topological. Both can be used to support decision making processes in many applications such as in information diffusion, viral marketing and epidemiology. Online Social...
