  1. 6. Security of Time Synchronization for PMU-based Power System State Estimation: Vulnerabilities and Countermeasures

    Författare :Ezzeldin Shereen; György Dán; Joe H. Chow; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phasor measurements unit; Time synchronization; Power system state estimation; Network Security; Time synchronization attacks; Precision time protocol; Machine learning; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Phasor Measurement Units (PMUs) constitute an emerging technology that is essential for various smart grid applications such as phase angle monitoring, power oscillation damping, fault localization, and linear state estimation. To obtain precise PMU measurements of voltage and current phasors, time synchronization in the order of 1 microsecond is typically required. LÄS MER

  3. 7. Distributed Monitoring and Resource Management for Large Cloud Environments

    Författare :Fetahi Zebenigus Wuhib; Rolf Stadler; Danny Raz; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; decentralized management; engineering protocols; distributed monitoring; resource management; Telecommunication; Telekommunikation; Computer science; Datalogi;

    Sammanfattning : Over the last decade, the number, size and complexity of large-scale networked systems has been growing fast, and this trend is expected to accelerate. The best known example of a large-scale networked system is probably the Internet, while large datacenters for cloud services are the most recent ones. LÄS MER

  4. 8. Improving the Adaptability of the End-host : Service-aware Network Stack Tuning

    Författare :Alexander Rabitsch; Anna Brunström; Per Hurtig; Stefan Alfredsson; Michael Welzl; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; transport layer; 5G; transport services; mobile broadband; network slicing; latency; availability; service optimization; multi-connectivity; Computer Science; Datavetenskap;

    Sammanfattning : The Internet of today is very different from how it used to be. Modern networked applications are becoming increasingly diverse. Consequently, a variety of requirements must be met by the network. Efforts to make the underlying mechanisms of the Internet more flexible have therefore been made to adapt to this diversification.

  5. 9. A Bottom-Up Approach to Real-Time Search in Large Networks and Clouds

    Författare :Misbah Uddin; Rolf Stadler; Jürgen Schönwälder; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Networked systems, such as telecom networks and cloud infrastructures, generate and hold vast amounts of conguration and operational data. The goal of this work is to make all this data available through a real-time search process named network search , which will enable new real-time management solutions. LÄS MER

  7. 10. Efficient synchronization and coherence for nonuniform communication architectures

    Författare :Zoran Radović; Erik Hagersten; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; Computer Science;

    Sammanfattning : Nonuniformity is a common characteristic of contemporary computer systems, mainly because of physical distances in computer designs. In large multiprocessors, the access to shared memory is often nonuniform, and may vary as much as ten times for some nonuniform memory access (NUMA) architectures, depending on if the memory is close to the requesting processor or not.
