Efficient resource lookup is essential for peer to peer networks and DHT (Distributed Hash Table) provides an ideal solution for resource lookup in distributed networks. Chord is a representative peer to peer lookup service based on DHT. The topology of Chord is modeled as a directed graph. There is a unidirectional link from a node to its every routing table entry node. In this paper, we propose to model the topology of Chord as a bidirectional graph. A reverse link is added for each original unidirectional link and such a pair of symmetrical links is maintained by a single heart-beat message. Then each node should maintain a finger table and a reverse finger table at very little additional cost. However, such reverse fingers may help to improve the lookup efficiency greatly. Theoretical analyses and experimental results both approve such improvements. |
