  1. 6. Enabling and Achieving Self-Management for Large Scale Distributed Systems : Platform and Design Methodology for Self-Management

    Författare :Ahmad Al-Shishtawy; Vladimir Vlassov; Seif Haridi; Peter Van Roy; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Autonomic Computing; Self-Management; Distributed Systems; Computer science; Datavetenskap;

    Sammanfattning : Autonomic computing is a paradigm that aims at reducing administrative overhead by using autonomic managers to make applications self-managing. To better deal with large-scale dynamic environments; and to improve scalability, robustness, and performance; we advocate for distribution of management functions among several cooperative autonomic managers that coordinate their activities in order to achieve management objectives.

  2. 7. 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

  3. 8. Overlay Multicast Networks : Elements, Architectures and Performance

    Författare :Doru Constantinescu; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Today, the telecommunication industry is undergoing two important developments with implications on future architectural solutions. These are the irreversible move towards Internet Protocol (IP)-based networking and the deployment of broadband access. LÄS MER

  4. 9. Live Streaming Performance of Peer-to-Peer Systems

    Författare :Ilias Chatzidrossos; György Dán; Renato Lo Cigno; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In peer-to-peer (P2P) live streaming systems peers organize themselves in an overlay and contributewith their resources to help diffuse live content to all peers in a timely manner. The performanceof such systems is usually characterized by the delay-loss curve, which quantifies theplayback delay required for achieving a certain streaming quality, expressed as the chunk missingratio at the peers.

  5. 10. Churning losses and efficiency in gearboxes

    Författare :Martin Andersson; Ulf Olofsson; Stefan Björklund; Ulf Sellgren; Bo Alfredsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gears; efficiency; temperature; running-in; assembly; torque loss; surface roughness;

    Sammanfattning : Efficient transmissions systems are key to producing competitive motor vehicles that have a smaller environmental impact. Gears are the main components in vehicle transmissions and although they are already highly efficient, there is still room for improvement. LÄS MER
