The success of technologies such as Gnutella, Kazaa, and Napster has launched peer-to-peer music sharing into the spotlight. More recently, both the research and industrial communities have recognized that the peer-to-peer paradigm can be used for a variety of applications beyond music sharing. However, in order to make more advanced applications viable, a number of research challenges must be addressed. In this talk, we present Pixie, an architecture that addresses two limitations of existing content exchange systems. Pixie improves peer-to-peer search by reducing the number of messages required to locate content. Also, Pixie uses a one-to-many distribution scheme for more efficient delivery of content in peer networks. This architecture not only makes current peer-to-peer applications more efficient; it can enable similar applications in next-generation environments where peers may be small, resource-constrained devices.
