High Performance Simulation Platform for Switching and Scheduling

Simulation is a significant way for performances' evaluations in switching and scheduling. The simulation software currently being existed has somewhat limitations in inheritability and extensibility. Based on current switching fabrics, by employing system level design method and object oriented technology, we designed and implemented a simulation platform called SPES for switching and scheduling. Input queuing, output queuing, combined input output queuing and combined input cross-point queuing and corresponding scheduling policies are integrated. Inheritability and extensibility attributes are obtained by designing traffic sources, switching fabrics and scheduling policies separately, and it can support multi-fabric, variable size packets and quality of service model's simulations. By configuring the platform through a uniform view, users can easily fulfill their concrete simulation environment.
