In this paper we propose a simple replication algorithm for Chord [SML+01]. The algorithm does not require extra space for the placement or the management of the replicas which are well-distributed to the nodes of the system. Replica holders can be easily calculated so nodes can choose the closest one to route their requests. We provide experimental results to show that replicated Chord has better performance not only from a non replicated Chord system but also from a replicated version of Chord based on the use of multiple hash functions.
