Abstract

Distributed Hash Tables (DHTs) have been used in Peer-to-Peer networks to provide query lookups in typically O(log n) messages whilst requiring maintenance of only small amounts of routing state. We propose ROME, a layer which runs on top of the Chord DHT to provide control over network size through monitoring of node workload and propose the use of processes to control the addition or removal of nodes from the network. We show that this technique can reduce further the hop counts in networks where available node capacity exceeds workload, without the need to modify any processes of the underlying Chord protocol.
