A grid-based architecture for recording and replay of civil-engineering hybrid remote experiment

In case of conducting a remote experiment among researchers around the world, some users might not be able to participate in the experiment due to some schedule conflicts, different time zones, etc. Accordingly, it is necessary to provide a recording and replay service that allows users to review the experiments that they have missed. In this paper, we suggest a grid-based system that not only conducts experiment remotely in real time but also records and replays the result for later use. The proposed architecture for recording and replay services is based on Globus Toolkit. It also uses a streaming server called Narada Brokering which is based on a publish-subscribe paradigm. The proposed system was designed for a hybrid remote experiment prototype for Real Time Hybrid Testing Facility in Korea Construction Engineering Development (KOCED) project. We hope that the proposed system will increase the usefulness of the result of the previously-conducted experiment as well as eliminate the cost of duplicating the previous experiments. A preliminary performance evaluation of the system is presented.
