Paper Abstract:
|
A distributed multiple server system is designed and implemented with Web-DB based services, which can play an important role not only to provide an environment for cooperative learning but also to support a function for emergency communication. In many instances, such an environment or a function used to be designed as so-called dedicated system, which can perform only single purpose. In other words, these different functions frequently seem to be mutually exclusive so that they may be realized independently with absolutely different methodologies. In our case, however, two different specifications have been accomplished by one identical system. The system has employed multiple servers located in a distributed campus network environment. Each server has multi-core processors. With virtualized CPUs by server virtualization, some programs are executed in parallel (on the virtual servers) so that our system can efficiently perform several functions. Based on our related works, two major applications are realized on the system. It can provide a cooperative learning environment for educational tool as well as Web-based surveillance functions for emergency contact. |
