Abstract: This paper presents the event based transaction level modeling for traffic management, including communication interface function encapsulation, the modeling approach of pipeline and scheduling structure.At the same time, the realization of payload event queue makes it convenient to control the latency and throughput.Using the non-event based and event based transaction level modeling approach realizes packet scheduling used in the traffic management and compare the simulation time.The simulation result shows that event based transaction level modeling accelerates the simulation.As a result, Event-based transaction level modeling reduce the development period.
