1. 1. 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

3. 2. 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.

4. 3. Programming Model and Protocols for Reconfigurable Distributed Systems

   Författare :Cosmin Ionel Arad; Seif Haridi; Gregory Chockler; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; distributed systems; programming model; message-passing concurrency; nested hierarchical composition; reactive components; software architecture; dynamic reconfiguration; multi-core; discrete-event simulation; peer-to-peer; testing; debugging; distributed key-value stores; data replication; consistency; linearizability; network partition tolerance; consistent hashing; self-organization; scalability; elasticity; fault tolerance; consistent quorums;

   Sammanfattning : Distributed systems are everywhere. From large datacenters to mobile devices, an ever richer assortment of applications and services relies on distributed systems, infrastructure, and protocols. Despite their ubiquity, testing and debugging distributed systems remains notoriously hard. LÄS MER

5. 4. Designs and Analyses in Structured Peer-To-Peer Systems

   Författare :Sameh El-Ansary; RISE; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Peer-to-Peer (P2P) computing is a recent hot topic in the areas of networking and distributed systems. Work on P2P computing was triggered by a number of ad-hoc systems that made the concept popular. Later, academic research efforts started to investigate P2P computing issues based on scientific principles. LÄS MER
