1. 1. Enabling Internet-Scale Publish/Subscribe In Overlay Networks

   Författare :Fatemeh Rahimian; Seif Haridi; Šarunas Girdzijauskas; Márk Jelasity; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Publish Subscribe; Content Distribution; Peer-To-Peer Overlay Network; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning : As the amount of data in todays Internet is growing larger, users are exposedto too much information, which becomes increasingly more difficult tocomprehend. Publish/subscribe systems leverage this problem by providingloosely-coupled communications between producers and consumers of data ina network. Data consumers, i.e. LÄS MER

3. 2. Towards a framework for analyzing IT strategy management in public sector : a case for IT organisations in the public sector

   Författare :Anayanci López Poveda; Paul Johannesson; Lazar Rusu; Anne Håkansson; KTH; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; IT strategy management; strategic management of IT; IT service management; public sector; small medium sized IT organizations.; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning : Small/medium sized public sector IT organisations combine several characteristics that difficult the effective use of an IT strategy. Research has reported small/medium sized organisations as using unstructured and informal IT management initiatives, which frequently leads to inexistent or incipient use of IT strategy. LÄS MER

4. 3. Design and Implementation of Centrally-Coordinated Peer-to-Peer Live-streaming

   Författare :Roberto Roverso; Seif Haridi; Sameh El-Ansary; Jim Dowling; Peter Van Roy; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; peer-to-peer; live-streaming; nat traversal; Electrical engineering; Elektroteknik; Computer engineering; Datorteknik; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning : In this thesis, we explore the use of a centrally-coordinated peer-to-peer overlay as a possible solution to the live streaming problem. Our contribution lies in showing that such approach is indeed feasible given that a number of key challenges are met. LÄS MER

5. 4. On the Performance Analysis of Large Scale, Dynamic, Distributed and Parallel Systems

   Författare :John Ardelius; Seif Haridi; Supriya Krishnamurthy; Mark Jelasity; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Performance analysis distributed systems; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning : Evaluating the performance of large distributed applications is an important and non-trivial task. With the onset of Internet wide applications there is an increasing need to quantify reliability, dependability and performance of these systems, both as a guide in system design as well as a means to understand the fundamental properties of large-scale distributed systems.
