Network Friendly P2P-TV: The Napa-Wine Approach

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, exploit ALTO-like services to optimize topology and performance, and to minimize the overall network load. The Topology Management and Chunk Trading are implemented on top of a set of generic libraries (GRAPES Generic Resource Aware P2P Environment for Streaming) which provide all the basic functionalities needed for peer sampling, for chunk scheduling, for exchanging buffer maps and chunk ID sets, for sending and receiving chunks, etc.
