Though the peer-to-peer network based on distributed hash table has scalability and availability features, but most of the distributed hash tables lack the support for the atomic data accessing, this ability is important to build data structures on distributed system. This paper gives the design and implementation of an atomic accessible mutable distributed hash table-- FamDHT. The FamDHT use the Paxos[1] distributed consensus protocol to ensure that the simultaneous access to data will be executed under a total order agreement. The FamDHT is build on top of the Bamboo DHT[2], a robust, open-source DHT implementation. At the end of the paper, an evaluation was given.
