Abstract: This paper proposes a distributed file system model which is based on Erasure code theory,and discusses its key technologies and implementation.First it introduces some conceptions of file system as well as the distributed file system,then it brings forward a distributed file system model based on Erasure code.Afterward some solutions for the key technologies such as error correction,cache mechanism and garbage collection are given.Finally it comes with a brief implementation and evaluates the performance.
