Pixie: a jukebox architecture to support efficient peer content exchange

Peer-to-peer (P2P) content exchange has recently gained attention from both the research and industrial communities. The dynamic nature of peer networks and the resource constraints of peer hosts have introduced a number of unique technical challenges that must be addressed to make large-scale P2P content exchange applications viable. In this work, we present and evaluate Pixie, an architecture that integrates one-to-many distribution of content and peer networks. Pixie provides a valuable data location service as well as a number of scalability properties both in terms of data location and content distribution. Our results indicate that, using a one-to-many scheme, we can significantly reduce the resources consumed in searching for and distributing content across peer networks. These scalability properties will become increasingly important as peer content exchange is extended to support more advanced applications.
