4. Researches on Grid Application of K*Grid

Research on Grid application has been conducted as a part of the K*Grid Project. Its primary goal is to develop Grid-based applications to improve the quality of service via Grid technology and to gather requirements from various applications for further research. Scientific application had been the major focus until 2004, and now its focus has shifted to IT applications such as on-line game service, telematics navigation service and rendering service.

Grid-based Telematics Navigation Service

Firstly we developed a high quality telematics navigation service based on Grid Technology. It serves realistic 3D image content in the Grid environment. The Grid-based telematics navigation service is composed of four elements: Grid-based load-balancer, navigation client, 3D image provider and load monitoring agent.

Grid based Online Game Service

The objective is to develop a high quality online game service on the Grid environment and allocate a real-time game server according to the number of concurrent game users. We developed an online game server from a Grid pool constructed by MoreDream middleware that manages game daemons. It is composed of four elements: lobby host, room host, data center and monitoring tool (Figure 3).

Grid based Rendering Service

The objective of Grid based rendering service is to accomplish a commercial or non-commercial rendering project on the Grid environment. Locally distributed render farms (Daejeon, Seoul) are interoperated by RenMan™ , which manages and accomplishes rendering services based on the Grid. Table 1 below shows what has been accomplished in the system.
