- This paper addresses a simple question: Is there a
behavior pattern of an individual node in peer-to-peer systems?
It is known that peer-to-peer systems collectively show daily
patterns, but the behavior patterns of individual nodes have
seldom been studied. If individual nodes have their own behavior
patterns with reasonable accuracy, we could greatly improve
the efficiency of the system by reducing the overhead to handle
unexpected random node failures.
Even though there have been many empirical studies on peerto-
peer systems, most of them are focusing on a collective view to
characterize the whole systems in terms of average availability,
average session length, and so on. In this paper we present Peer
Availability Table (PAT) which is a model to represent a behavior
pattern of an individual node based on the measurement of node
availability. To judge the existence of the behavior pattern, we
measure the performance of PAT using a binary classification
test. By answering the basic question, we provide a useful hint
for the design of peer-to-peer systems.
