Performance improvement of distributed file system using tunneling

The paper deals with the modern concepts of distributed and hierarchical storage systems. Because of the high capacity of modern storage devices, the increasing number of files stored in such systems and the new client access patterns of mobile devices, the architecture of storage systems needs improvement to perform efficiently and respond to the current needs. Our model covers the traditional hierarchical and distributed approaches; as well as algorithms to efficiently organize the inner storage behavior. We evaluate the typical scenarios in the resulting model and show its advantages.
