                         •   Jan. 6~20, 2009 (2 weeks)
                         •   Packet loss is zero.
                         •   RTT is stable.
                         •   We avoid Chicago area
                             congestions by direct
                             network from Seattle.

     Summary

        Data processing for CDF has been
         developed from CAF (Central Analysis
         Farm) to Grid.

        KISTI is one of leading institutes of CDF
         data processing.
