Abstract-- The paper1
focuses on distributed file systems in
P2P networks. We introduce a novel file replication scheme
which is adaptive, reacting to changes in the patterns of
access to the file system by dynamically creating or deleting
replicas. Replication is used to increase data availability
in the presence of site or communication failures and to de-
crease retrieval costs by local access if possible. Our system
is completely decentralized and nodes can be removed/added
dynamically. We also propose an overlay architecture for
file search. This architecture is structured, but also based
on random walk. Our system has a mobile agent which
performs dynamic load-balancing. This agent is event driven
and circulates in the network to find and "destroy" the
