Distributed Hash Tables: Design and Applications
Route length can be greater than diameter, since the greedy routing algorithm may not find shortest paths. Locality-preserving hashing ensures that similar keys are assigned to similar objects.

Need Help? The structure of a DHT can be decomposed into several main components.

This process is experimental and the keywords may be updated as the learning algorithm improves. Finally, DHTs must deal with more traditional distributed systems issues such as load balancing , data integrity , and performance in particular, ensuring that operations such as routing and data storage or retrieval complete quickly. Internet Domain Survey. However, research into effective defences against Sybil attacks is generally considered an open question, and wide variety of potential defences are proposed every year in top security research conferences.

We also present several applications which illustrate the power of DHTs in enabling large-scale peer-to-peer applications. Pervasive Computing and Communications, ENW EndNote. Persistent Link: Contrast this with a traditional hash table in which addition or removal of one bucket causes nearly the entire keyspace to be remapped.
When there is no such neighbor, then we must have arrived at the closest node, which is the owner of k as defined above.
Distributed hash table
Petar Maymounkov, one of the original authors of Kademlia , has proposed a way to circumvent the weakness to the Sybil attack by incorporating social trust relationships into the system design. This is a preview of subscription content, log in to check access. Each node maintains a set of links to other nodes its neighbors or routing table. Later versions of Gnutella clients moved to a dynamic querying model which vastly improved efficiency.
