Study on the Distributed Lookup Service of P2P Systems with Chord
Dong Fang · 2003
The core problem facing P2P systems is just the lookup service of P2P systems with Chord in a largescale Internet network. k. Chord provides a service that gives an efficient and robust implementation of a lookup service, and its scalability makes it practical for use in large P2P systems. It is very robust in the face of node failures as well as in the face of many simultaneous node failures. Also, chord provides an efficient mechanism to accommodate simultaneous nodes joins. The Shared File System (SFS) based on Chord is a P2P readonly storage system that providesproviding guarantees for the efficiency, robustness, and loadbalance of file storage and, retrieval. SFS does this with a completely decentralized architecture that can reach a large scale of systems. The core of the SFS software consists of two layers, i.e., DHT and Chord. SFS uses the Chord to locate the lookup service.
