P2P-TV systems have become part of the Internet landscape. The architecture of these (normally proprietary) applications is generally receiver-driven, in that receivers actively search for suitable peers to download from, trying to maximize their performance. The Napa-Wine EU project proposes an architecture where P2P-TV clients exploit network measures to reduce their network footprint and, if available,...
Scheduling the transmission of information in P2P applications is one of the main challenges, and one of the keys to success, for these applications. We concentrate on low-latency streaming applications (e.g. TV) and explore different combinations of chunk and peer scheduling strategies, finding that the majority of the proposals found in the literature are not robust to changing conditions. We then...
This paper describes SSSim, the Simple and Scalable Simulator for P2P streaming systems. SSSim is designed for performance and scalability, and allows the simulation of the diffusion of a very large number of chunks over large number of peers in reasonable times. This result has been obtained by optimising the simulator for recurrent workloads and minimizing the memory footprint. After describing...
