摘要: 针对天地一体化网络中用户数量多、并发通信高和时变性的特点,基于多尺度虚拟化技术,提出一种模型驱动的分布式卫星终端用户行为仿真方法。采用多尺度虚拟化技术解决仿真逼真性和计算开销间的矛盾,实现卫星终端的大规模仿真。利用模型驱动的设计方法,将理论模拟模型与网络仿真相结合,实现用户行为特征的高逼真仿真。实验结果表明,该方法可以实现100万用户在线、10万并发通话的大规模仿真,且能准确体现用户行为的时变规律。

Abstract: Aiming at the characteristics of large number of users,high concurrent communication and time-varying in the space-ground integrated network,a model-driven distributed satellite terminal user behavior simulation method is proposed based on multi-scale virtualization technology.The multi-scale virtualization technology is used to effectively overcome the contradiction between simulation fidelity and computational overhead,and large-scale simulation of satellite terminals are realized.Using the model-driven design method,the theoretical simulation model can be combined with network simulation to achieve high-fidelity simulation of user behavior characteristics.Experimental results show that the proposed method can accurately realize large-scale simulation of 1 million online users and 100 thousands concurrent calls,and can accurately reflect the time-varying features of user behavior.

Key words: space-ground integrated network, network simulation, user behavior simulation, model driven, multi-scale virtualization
