PSPChord - A Novel fault tolerance approach for P2P overlay network

Abstract

In this paper, we propose a novel approach called PSPChord to provide efficient fault tolerance solution for Chord-based P2P overlay networks. In our proposal, the successor list is removed, instead, we design the partition-based data replication and modify finger tables. While the partition strategy is used to distribute data replicas evenly on Chord ring to reduce and balance the cost of lookup request, the finger table is added links to successor and predecessor of neighboring nodes to pass over faulty nodes. By simulating, our experiments already showed the performance of PSPChord as compared with original Chord in resolving fault tolerance problem on P2P overlay network.
