Performance Evaluation of Home Gateway System Based on GSPN

With the rapid development of Internet and home automation technology, the Internet-based home gateway system has become the focus in embedded areas. Home gateway system is a complex system with typical business process characteristics. However, there is little research work made on it with workflow principle. Still less some achievement in analyzing the time feature of the real time system service. In this paper, two modeling methods-GPSN and workflow are combined to model home gateway system. First, a GPSN workflow model is proposed. According to empirical data,certain parameters are assigned to each transition in the model. Then the time feature of status inquiry service is analyzed with performance analysis method based GSPN.Finally, some information, such as system bottleneck points,are obtained that facilitate further system optimization.
