Lookup-Ring: Building Efficient Lookups for High Dynamic Peer-to-Peer Overlays
This paper is motivated by the problem of poor searching efficiency in decentralized peer-to-peer file-sharing systems. We solve the searching problem by considering and modeling the basic trade-off between forwarding queries among peers and maintaining lookup tables in peers, so that we can utilize optimized lookup table scale to minimize bandwidth consumption, and to greatly improve the searc...
متن کاملEfficient semantic search on DHT overlays
Distributed hash tables (DHTs) excel at exact-match lookups, but they do not directly support complex queries such as semantic search that is based on content. In this paper, we propose a novel approach to efficient semantic search on DHT overlays. The basic idea is to place indexes of semantically close files into same peer nodes with high probability by exploiting information retrieval algori...
متن کاملEfficient Routing for Peer-to-Peer Overlays
Most current peer-to-peer lookup schemes keep a small amount of routing state per node, typically logarithmic in the number of overlay nodes. This design assumes that routing information at each member node must be kept small, so that the bookkeeping required to respond to system membership changes is also small, given that aggressive membership dynamics are expected. As a consequence, lookups ...
متن کاملBuilding Topology-Aware Overlays using Global Soft-State
Distributed hash table (DHT) based overlay networks offer an administration-free and fault-tolerant storage space that maps “keys” to “values”. For these systems to function efficiently, their structures must fit that of the underlying network. Existing techniques for discovering network proximity information, such as landmark clustering and expanding-ring search are either inaccurate or expens...
