  • GCC - Design and Implementation of Grid File Management System Hotfile
    Lecture Notes in Computer Science, 2004
    Co-Authors: Liqiang Cao, Jie Qiu, Li Zha, Yuzhong Sun
    Abstract:

    Hotfile is a user level file management system. It wraps GridFTP and GASS or any other file transfer protocol compatible with hotfile structure into a unified vegafile protocol. Based on virtual grid file layer and a set of basic grid file operations, users can access grid file without knowing the physical transport protocol of the file. Test result shows the overhead of vegafile protocol is little in file transfer and operation. Further vegafile transfer experiment shows when file size is smaller than 1M byte, Vega file copy with GASS has Higher Bandwidth, where as file is larger than 1M byte, Vega file copy with GridFTP has Higher Bandwidth.

  • Higher Bandwidth x
    ACM Multimedia, 1994
    Co-Authors: J. Danskin
    Abstract:

    Network Bandwidth has always been a key issue for multimedia protocols. Many potential users of networked multimedia protocols will continue to have low Bandwidth network connections for some time: copper wire ISDN, infra-red, cellular modems, etc.. Compression provides potential relief for users of slow networks by increasing effective Bandwidth. Higher Bandwidth X (HBX) introduces a new technique, based on arithmetic coding and statistical modeling, for compressing structured data. Applied to the X networked graphics protocol, this technique yields 6.3:1 compression across a representative set of traces, performing twice as well as the popular LZW-based Xremote compression protocol. HBX's coding techniques are generally applicable to the graphics and imaging subset of multimedia protocols. Future work will determine whether HBX's coding techniques can be applied to audio and video streams as well.
