Abstract:
Simulation has e a significant way for performance evaluations in switching and scheduling,
however, the existing simulation softwares have some limitations in inheritability and extensibility. Based on the
current crossbar switching fabric, by employing system level design method, and object oriented technology, a
simulation platform called SPES (switching performance evaluation system) for switching fabrics and scheduling
policies’ developments are designed and implemented. Input queuing, output queuing, combined input-output
queuing bined input-crosspoint 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 exhibits good performances for supporting multi-fabric, variable packets sizes and QoS model’s
simulations. By configuring the platform through a uniform view, users can fulfill their concrete simulation
environment. Besides, it can carry out end to end performances’ evaluations with little modification. Finally, this
paper presents a simulation case based bined input-
