Resumo: | Peer-to-peer is emerging as a new paradigm for distributed computing. Its continuing growing, however, depends on the development of mechanisms that guarantee the scalability of the networks. This work analyzes the utilization of caching systems in peer-to-peer environments, reducing bandwidth requirements and user-perceivedlatency, and increasing the availability of the services. Besides serving content of a specific network, such caching system may also act as a gateway among different peer to-peer systems, making possible that clients of one system have access to the available resources in any of the connected systems. We designed a proxy architecture that fulfills these requirements and applied it to two popular P2P networks: DirectConnect and eDonkey. Simulation results show that our caching strategy allows the reduction of user latency and the increase of the resource availability |
