Tornado: a capability-aware peer-to-peer storage network

摘要: Peer-to-peer storage networks aim at aggregating the unused in today's resource-abundant computers to form a large, shared space. To lay over extremely variant machines, and administrative organizations, peer-to-peer must be aware of capabilities constituent components leverage their resources, performance reliability. This paper reports our design such network, called Tornado. Tornado is built on top two concepts. The first virtual home concept, which adds an extra level abstraction between data nodes mask underlying heterogeneity. second concept classification into "good" "bad" according static dynamic capabilities. Only peers can host homes, whereby introducing quality services network. We evaluate via simulation. results show that comparable with previous systems, where each route takes most [log N] hops, anew node N]/sup 2/ messages join, memory overhead O(log N). Moreover, able provide comprehensive features scattered different systems previously, account exploits heterogeneity network environment.
