  1. 1. A study of the reliability of optical switching nodes for high capacity telecommunications networks

    Författare :Lena Wosinska; KTH; []
    Nyckelord :;

    Sammanfattning : The use of optical fibers and optical network componentsallows aggregating the bit streams in order to minimize theequipment that is necessary for transmission and switching. Inthis way, however, the robustness of the network totransmission failures is decreased, i.e., number of servicesthat can be affected magnifies the effect of failure. LÄS MER

  3. 2. Dynamic Resource Provisioning and Survivability Strategies in Optical Networks

    Författare :Jawwad Ahmed; Lena Wosinska; Andrea Fumagalli; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical networks; passive optical networks; wavelength; routing; Survivability; protection; restoration; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Sammanfattning : Optical networks based on Wavelength Division Multiplexing (WDM) technology show many clear benefits in terms of high capacity, flexibility and low power consumption. All these benefits make WDM networks the preferred choice for today’s and future transports solutions which are strongly driven by a plethora of emerging online services. LÄS MER

  4. 3. Simulation-based development of distributed control systems in energy-efficient data centres

    Författare :Yulia Berezovskaya; Valeriy Vyatkin; Chen-Wei Yang; Lena Wosinska; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dependable Communication and Computation Systems; Kommunikations- och beräkningssystem;

    Sammanfattning : The main focus of this thesis is on the area of integrated automated control systems inmodern data centres. The data centres are mission-critical facilities since they provide services for transporting, storing and processing vast amounts of data, which can be considered the ”new oil” of the Industry 4.0 era.

  5. 4. Design, analysis and simultion for optical access and wide-area networks

    Författare :Jiajia Chen; Lena Wosinska; Hussein Mouftah; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fiber access networks; passive optical network; dynamic bandwidth allocation; reliability; switched optical networks; switching node; optical circuit switching; optical packet switching; routing and wavelength assignment; security; Telecommunication; Telekommunikation;

    Sammanfattning : Due to the tremendous growth of traffic volume caused by both exponential increase of number of Internet users and continual emergence of new bandwidth demanding applications, high capacity networks are required in order to satisfactorily handle the extremely large amount of traffic. Hence, optical fiber communication is the key technology for the network infrastructure. LÄS MER

  7. 5. Optical Interconnects for Next Generation Data Centers : Architecture Design and Resource Allocation

    Författare :Yuxin Cheng; Jiajia Chen; Lena Wosinska; Po Dong; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : The current data center architectures based on blade servers and elec- tronic packet switches face several problems, e.g., limited resource utilization, high power consumption and cost, when handling the rapidly growing of data traffic. LÄS MER
