SERVERLESS DISTRIBUTED FILE SYSTEM

摘要

PROBLEM TO BE SOLVED: To manage the memory of files and directories using one or more directory groups. SOLUTION: The directories can be managed using Byzantine-fault-tolerant groups, and the files are managed without using the Byzantine-fault-tolerant groups In addition, this file system can store files using a hierarchical name space. This directory group can use a plurality of locks that control access to objects (for instance, file and directory) in every directory.
