  1. 1. Reliability versus Cost in Next Generation Optical Access Networks

    Författare :Mozhgan Mahloo; Lena Wosinska; Jiaji Chen; David B Payne; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber access network; passive optical network; reliability; techno-economic study; next generation optical access; network protection; wavelength division multiplexing;

    Sammanfattning : The ever increasing demands of Internet users caused by the introduction of new high bandwidth applications and online services as well as the growing number of users and devices connected to the Internet, bring many challenges for the operators, especially in the last mile section of the network. Next generation access architectures are expected to offer high sustainable bandwidth per user. LÄS MER

  3. 2. Exploring the Dynamics of Security Community-Building in the Post-Cold War Era : Spain, Morocco and the European Union

    Författare :Niklas Bremberg; Jan Hallenberg; Charlotte Wagnsson; Jacob Westberg; Ian Manners; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; security; community; practice; institution; constructivism; crisis management; transgovernmental; network; European Union; Spain; Morocco; trade; defence; civil protection; Political Science; statsvetenskap;

    Sammanfattning : This thesis aims to make a theoretical as well as an empirical contribution to the debate on the security community concept in International Relations (IR) by way of conducting a study of the European Union (EU) as a security community-building institution in the case of Spain and Morocco. The security community concept originally sought to define the conditions under which the threat of inter-state war would be mitigated through social transaction and expectations of peaceful change between societies and states.

    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

  5. 4. Provisioning Strategies for Transparent Optical Networks Considering Transmission Quality, Security, and Energy Efficiency

    Författare :Amornrat Jirattigalachote; Lena Wosinska; Paolo Monti; Biswanath Mukherjee; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transparent optical networks; routing and wavelength assignment; physical-layer impairments; signal quality; differentiation of services; physical-layer attacks; power equalizers; Greedy Randomized Adaptive Search Procedure GRASP ; green networks; energy awareness; dedicated path protection; shared path protection; survivable WDM networks;

    Sammanfattning : The continuous growth of traffic demand driven by the brisk increase in number of Internet users and emerging online services creates new challenges for communication networks. The latest advances in Wavelength Division Multiplexing (WDM) technology make it possible to build Transparent Optical Networks (TONs) which are expected to be able to satisfy this rapidly growing capacity demand.

  7. 5. Design Principles for Network Distributed Denial of Service Defense

    Författare :Todd Booth; Karl Andersson; Tero Päivärinta; Antonios Michalas; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DRDoS; DDoS; Network Security; DSR; Information systems; Informationssystem;

    Sammanfattning : People, organizations and society are become more and more dependent upon access to Information Systems. Most Information Systems are accessible via the Internet. It is becoming easier and easier to perform successful network attacks against these Information Systems, which causes the system to become unavailable for its intended users. LÄS MER
