Peer-to-peer time-shifted streaming systems
Résumé
In live streaming systems (IPTV, life-stream services, etc.), an attractive service consists in allowing users to access past portions of the stream. This is called a time-shifted streaming system. In our vision, a centralized time-shifted streaming system face scalability and ethical issues, therefore, we address the problem of designing a peer-to-peer system where peers store and deliver past chunks. We first attempt to identify the main characteristics of time-shifted streaming system from well-known measurements of VoD and IPTV systems. These overlays are the first structures specifically designed for time-shifted streaming system. Although no evaluation is presented, these preliminary description aim to foster discussions on a critical service.
