    EOSC and the Free Riders
    (2016-11) Gfrerer, Margareth; Mogus, Solomon
    Big Data, Open Science and Technology are the topics on the agenda of the European Commission (EC) on one side and on the other side, ministries, research funding organizations, universities and public research institutions together with university libraries are bringing complaints about the access to scientific publications and research data also to the EC. Against these facts the EC has taken on the responsibility to realize the idea of Open Science and to favour the implementation of an European Open Science Cloud (EOSC), which “aims to develop a trusted, open environment for the scientific community for storing, sharing and reusing scientific data and results” (COM 2016). A High Level Expert Group (2016) has worked on the definition, the key trends in Open Science and the answer, how EOSC will be realized for the target group of European researchers and professionals in science and technology. The EOSC is an EU Member State Project. Non-European researchers can join the EOSC as free riders. Based on the findings of the HLEG this research will explore the question: What is the advantage for a research community from an emerging country to get a free rider position on the EOSC? This research is primarily a literature review. Discussions with international researchers and Ethiopian university management presents insights about the advantages of a free ride position on the EOSC. An overview between the free rider problem as discussed in economic literature and the invitation to free ride on WIKIPEDIA and EOSC will conclude this research.

    Responding To The Demands Of Big Data Scientific Instruments Through The Development Of An International Software Defined Exchange Point (Sdx)
    (2016-11) Ibarra, Julio; Bezerra, Jeronimo; Lopez, Luis Fernandez; Morgan, Heidi; Cox, Donald
    Science is being conducted in an era of information abundance. The rate at which science data is generated is increasing, both in volume and variety. This phenomenon is transforming how science is thought of and practiced. This transformation is being shaped by new scientific instruments that are being designed and deployed that will dramatically increase the need for large, real-time data transfers among scientists throughout the world. One such instrument is the Square Kilometer Array (SKA) being built in South Africa that will transmit approximately 160Gbps of data from each radio dish to a central processor. This paper describes a collaborative effort to respond to the demands of big data scientific instruments through the development of an international software defined exchange point (SDX) that will meet the network provisioning needs for science applications. This paper discusses the challenges of end-to-end path provisioning across multiple research and education networks using OpenFlow/SDN technologies. Furthermore, it refers to the AtlanticWave-SDX, a project at Florida International University and the Georgia Institute of Technology, funded by the US National Science Foundation (NSF), along with support from Brazil’s NREN, Rede Nacional de Ensino e Pesquisa (RNP), and the Academic Network of Sao Paulo (ANSP). Future work explores the feasibility of establishing an SDX in West Africa, in collaboration with regional African RENs, based on the planned availability of submarine cable spectrum for use by research and education communities.
