Abstract：
 The invention belongs to mesh data management and sharing technical area. Characters are that self-similar layered isomorphic architecture is adopted in the system granularity of node in the system can be adjusted arbitrarily. Thus, flexibility and extensibility of system are increased. Moreover, concept of super node is introduced in the system. Architecture full connection is adopted among these super nodes. The architecture reduces spending brought by huge route table to be maintained among nodes as well as influence on system caused by adding and quitting node frequently. The system includes two kinds of data: local metadata and global metadata. Global metadata makes storing and transferring data simpler but user does not need to change custom of use. Parsing method in step-by-step is adopted for searching metadata. Thus, message for querying location of copy is limited in local area as far as possible.
