ABSTRACT
Remote collaboration work via the Internet becomes common these days by appearance of web-based remote collaboration systems such as Google Apps, and SAGE2. This paper focuses on SAGE2 as a typical data intensive collaboration system, which shares information on large high-resolution displays with other sites using web browser technologies. However, it takes long time to share large files between SAGE2 systems. In order to improve the file sharing performance of SAGE2, this paper proposes a file sharing mechanism using Content Espresso, a distributed storage system for global large file sharing, which can be applied to other web-based collaboration systems. We implemented and evaluated the proposed mechanism by emulating a global network environment. The result of the evaluation confirms that the proposed mechanism has better performance than the existing file sharing mechanism on SAGE2 when RTT between SAGE2 systems is longer than 10 ms.

A multiple-file write scheme for improving write performance of small files in Fast File System
Fast File System (FFS) stores files to disk in separate disk writes, each of which incurs a disk positioning (seek + rotation) limiting the write performance for small files. We propose a new scheme called co-writing to accelerate small file writes in ...
