Network File System (NFS, de facto in Linux) or Common Internet File System (CIFS, de facto in Windows) is used for applications to move files across networks/grids. We prove that once a file is created with a set of attributes, such as name, type, permission mode, owner and owner group, its future access frequency is predictable. A decision-tree-based predictive model is established with an integrated fuzzy logic facility to further calculate the degree to which a file may be frequently accessed. By consulting with the rules generated from the predictive model over diverse real-system NFS traces, it can predict a newly created file’s future access frequency with a sufficient accuracy (greater than 90%).
