D2HT: The Best of Both Worlds, Integrating RPS and DHT
Distributed Hash Tables (DHTs) and Random Peer Sampling (RPS) provide important and complementary services in the area of P2P overlay networks. DHTs achieve efficient lookup while RPS enables nodes to build and maintain connectivity in the presence of high churn. Clearly, many applications, e.g. in the area of search, would greatly benefit if both these services were available together at a reasonable cost. This paper integrates a structured P2P overlay and a Random Peer Sampling service through gossip protocols. This system called D2HT, leverages the small-world nature of DHTs and relies on two cohabiting gossip protocols maintaining the close and long-range links respectively. The long links are chosen according to a harmonic distribution, following the Kleinberg small-world model. This approach exhibits several benefits: (i) The resulting DHT is highly dynamic and self-stabilizing, changes are tracked for free through the gossip nature of the protocol. This removes the need for ...
