Big Data are becoming a new technology focus both in science and in industry. This paper discusses the challenges that are imposed by Big Data on the modern and future Scientific Data Infrastructure (SDI). The paper discusses a nature and definition of Big Data that include such features as Volume, Velocity, Variety, Value and Veracity. The paper refers to(More)
There is a trend in the research networking community to provide e-Science applications with dedicated connections instead of shared links. Lightpaths are the way to guarantee the appropriate level of service in terms of bandwidth and latency. NDL – Network Description Language – is a data model offering users and providers of lightpaths with a common(More)
The Green Clouds project in the Netherlands investigates a system-level approach towards greening High-Performance Computing (HPC) infrastructures and clouds. In this paper we present our initial results in profiling virtual machines with respect to three power metrics, i.e. power, power efficiency and energy, under different high performance computing(More)
This paper describes the Infrastructure and Network Description Language (INDL). The aim of INDL is to provide technology independent descriptions of computing infrastructures. These descriptions include the physical resources and the network infrastructure that connects these resources. The description language also provides the necessary vocabulary to(More)
Current research networks allow end users to build their own application-specific connections (lightpaths) and optical private networks (OPNs). This requires a clear communication between the requesting application and the network. The network description language (NDL) is a vocabulary designed to describe optical networks based on the resource description(More)
This paper discusses the challenges that are imposed by Big Data Science on the modern and future Scientific Data Infrastructure (SDI). The paper refers to different scientific communities to define requirements on data management, access control and security. The paper introduces the Scientific Data Lifecycle Management (SDLM) model that includes all the(More)
This paper describes our approach to modeling computing infrastructures. Our main contribution is the Infrastructure and Network Description Language (INDL) ontology. The aim of INDL is to provide technology independent descriptions of computing infrastructures, including the physical resources as well as their network infrastructure. INDL also provides the(More)
The energy consumed by data centers hosting cloud services is increasing enormously. This brings the need to reduce energy consumption of different components in data centers. In this work, we focus on energy efficiency of the networking component. However, how different networking solutions impact energy consumption is still an open question. We(More)
The European Union Project Networking innovations Over Virtualized Infrastructures (NOVI) set out to design and implement a modular data, control andmanagement plane federation architecture, leading to an integrated experimental prototype mounted on interconnected European Future Internet testbeds. In this paper we present the components of this(More)
