3. Motivation of Introducing Grid Technology
- Performance
Providing the high contents and big size WRL
file to multiple users simultaneously The
Contents on navigation system should make the
user feel real. GRID Technology improves the
performance with fast processing from multiple
users and fast processing for big and high
content files simultaneously.
- Efficiencies
Maximizing the computing system
utilization Minimizing the limit with distributed
system and load balancing for users Minimizing
system down time
- Quest for Perfect Information
Improving searching performance on high volume
data Providing the single structural service
under heterogeneous computing environment

4. Plan for Applying Grid Technology

• Improving 3D file transfer performance of HTTP
  protocol

Wrl file that is 3D data file on 3D Navigation
system is on server side. When the user runs
navigation web application for the first time,
the files on the server are transferred with
using HTTP or other internet protocols to
clients. Data GRID can provide the best
performance when many clients request the high
volume media file (wrl file).
- Reflash load of 3D DATA
The wrl file that is 3D data file of 3D
navigation is different with media file or web
page. This doesnt have entire re-phrasing
process on changed server side file and it gets
only changed data with utilizing web log and
cache on the client. GRID Servers make Reflash
logic of WRL file much fast through supporting
simultaneous network transformation and running
multiple applications under distributed computing
environment.

4. Plan for Applying Grid Technology Continue

• Improving FPS (Frame Per Second) on real time
  navigation

FPS performance is depending on Servers network
performance because 3D spaces on 3D navigation
are loaded from server and it needs bigger
FPS. GRID system will show the better loading
multiple 3D spaces on 3D navigation system and
will have better rendering service with improved
FPS. Network capacity can effect the FPS on 3D
navigation system. Server should adjust the data
transfer for client to Server or server to
server. However, the server doesnt have
controller the data transfer, it causes the lower
FPS. GRID server will provide the better FPS with
excellent Network control.
