    Author : Kyoomars Alizadeh Noghani; Andreas Kassler; Andreas Fischer; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Data Center; Ethernet VPN; EVPN; Live Service Migration; Reconfiguration; SDN; Virtual Network Function; VNF; Computer Science; Datavetenskap;

    Abstract : Modern virtualized Data Centers (DCs) require efficient management techniques to guarantee high quality services while reducing their economical cost. The ability to live migrate virtual instances, e.g. READ MORE

  4. 2. Enhancing Salient Features in Volumetric Data Using Illumination and Transfer Functions

    Author : Daniel Jönsson; Anders Ynnerman; Kwan-Liu Ma; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The visualization of volume data is a fundamental component in the medical domain. Volume data is used in the clinical work-flow to diagnose patients and is therefore of uttermost importance. READ MORE

  5. 3. Energy-efficient resource provisioning for cloud data centers

    Author : Selome Kostentinos Tesfatsion; Johan Tordsson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Energy efficiency has become a fundamental concern in data centers, raising issues to all energy-related costs, including capital costs, operating expenses, and environmental impact. Energy inefficiency is mainly caused by unoptimized use of energy by sub-components of these data centers. READ MORE

  6. 4. Passive Optical Top-of-Rack Interconnect for Data Center Networks

    Author : Yuxin Cheng; Jiajia Chen; Lena Wosinska; Matteo Fiorani; Qiong Zhang; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optical communications; data center interconnects; MAC protocol; dynamic bandwidth allocation.; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : Optical networks offering ultra-high capacity and low energy consumption per bit are considered as a good option to handle the rapidly growing traffic volume inside data center (DCs). However, most of the optical interconnect architectures proposed for DCs so far are mainly focused on the aggregation/core tiers of the data center networks (DCNs), while relying on the conventional top-of-rack (ToR) electronic packet switches (EPS) in the access tier.

  7. 5. Towards Unifying Stream Processing over Central and Near-the-Edge Data Centers

    Author : Hooman Peiro Sajjad; Vladimir Vlassov; Johan Tordsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; geo-distributed stream processing; geo-distributed infrastructure; edge computing; edge-based analytics; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : In this thesis, our goal is to enable and achieve effective and efficient real-time stream processing in a geo-distributed infrastructure, by combining the power of central data centers and micro data centers. Our research focus is to address the challenges of distributing the stream processing applications and placing them closer to data sources and sinks. READ MORE
