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.

摘要： 网络仿真是进行网络规划和协议设计的重要手段，设计人员亟需构建高效的仿真系统。针对主流网络仿真器在场景建模方面存在效率不高和灵活性不够的问题，提出一种基于统一描述和中间件适配的高效可扩展的场景建模机制。基于模型层标签高效描述仿真场景，然后通过中间件解析器适配到不同的仿真器，从而大大提高仿真建模效率。最后通过应用实例验证了该场景建模机制的有效性和广泛适用性，对构建高效可扩展的网络仿真系统具有一定的借鉴意义。
