Abstract
Peer­to­peer systems contain a collection of equiva­
lent entities that form an application­layer overlay net­
work. Each entity acts as client, server, and overlay
network router. Peer­to­peer systems enable the rapid
development of distributed applications; in short order,
peer­to­peer file sharing has become one of the most
popular Internet applications. There are two primary
functions in a peer­to­peer file sharing application: con­
tent discovery (determining which peers have the de­
sired content) and content retrieval (transferring content
from a peer to the requester). We focus on two aspects
of content retrieval that have received limited attention,
namely peer selection and request buffering. Using a
