Rollerchain: A DHT for Efficient Replication

In this paper we present Roller chain, a novel Distributed Hash Table that offers efficient data storage through the combination of gossip-based and structured overlay networks. The unstructured component maintains clusters of fully connected nodes, where each cluster acts as a virtual node in the structured component. This architecture simplifies the management of data replication and balances the load among nodes in the system. We have implemented a prototype of Roller chain that we have used to experimentally validate its performance against other state of the art solutions.
