Abstract
Over the Internet today, there has been much interest
in emerging Peer-to-Peer (P2P) network overlays because they
provide a good substrate for creating data sharing, content
distribution, and application-level multicast applications. There
are two classes of P2P overlay networks: structured and unstructured.
Structured P2P networks can efficiently locate items,
but the search is not user friendly. Conversely, unstructured P2P
networks have a easy mechanism to search a content, but the
lookup process is inefficient. In this paper, we propose an hybrid
structured and unstructured topology in order to take advantages
of both kind of networks. In addition, our proposal guarantees
that if a content is at any place in the network, it will be reachable
with probability one. Simulation results show that the behaviour
of the network is stable and that the network distributes the
contents efficiently to avoid network congestion.Este trabajo ha sido subvencionado por el proyecto nacional
