1. 1. A System, Tools and Algorithms for Adaptive HTTP-live Streaming on Peer-to-peer Overlays

   Författare :Roberto Roverso; Seif Haridi; Jim Dowling; Alberto Montresor; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; peer-to-peer; distributed caching; nat traversal; congestion control; adaptive HTTP streaming; live streaming; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning : In recent years, adaptive HTTP streaming protocols have become the de facto standard in the industry for the distribution of live and video-on-demand content over the Internet. In this thesis, we solve the problem of distributing adaptive HTTP live video streams to a large number of viewers using peer-to-peer (P2P) overlays. LÄS MER
