Abstract: Network simulation plays a crucial role in network planning and protocol design. Recent network designers show urgent need for efficient simulation system. However, mainstream network simulators are generally inefficient and less flexible in scenario modeling. This paper proposes an efficient and scalable mechanism based on unified description and middleware adaptation. By efficiently using model layer tag to describe simulation scenario, and adapting to different simulators by middleware program, the proposed mechanism greatly improves simulation modeling efficiency. Applications show that this method is efficient, and is significative for other network simulation system.
