Implement Fault Tolerant in distributed DEVS simulation

Fault Tolerant plays an important role in maintaining the stability of system. Distributed DEVS simulation has been accepted as an effective approach to solve complex problems. This paper presents a DEVS framework supporting Fault Tolerant with the help of distributed DEVS simulators. The framework consists of the components such as Master, Logger, Model Server and Root Server. Fault Detection, States Storage and Fault Recovery are integrated inside the components to realize Fault Tolerant. We optimize the framework by finding an appropriate Timeout in experiments.
