摘要

现有卫星网络仿真聚焦通信接入、网络路由等网络层的系统评估，难以满足未来卫星网络多功能融合场景下的仿真验证需求。针对以上问题，提出一种数实融合、云网融合的大规模卫星云网仿真方法，基于虚拟化技术构建通信、网络、计算功能融合的卫星网络节点，通过高精度的链路模拟实现卫星网络时变拓扑的模拟，通过数实接口实现数字空间和物理实体空间的交互，最终构建一张数实融合的规模卫星云网，以期为未来卫星网络的仿真验证提供有效支撑。

Abstract

Existing satellite network simulations focus on system assessments of network layer functions and performance such as communication access and network routing

which are insufficient to meet the simulation verification requirements in scenarios where communication

networking

and computing functions are integrated. In view of the above problems

this paper proposed a large-scale satellite cloud network simulation method that integrated digital and physical domains and cloud-network convergence. By utilized virtualization technology to constructed nodes with integrated communication

networking

and computed functions

high-precision simulation of dynamic and time-variant topologies of satellite networks was achieved through topological connection relationships. Interaction between the digital space and the physical entity space was realized through a digital-physical interface

ultimately constructing a large-scale satellite cloud network that integrated the digital and physical domains. This Approach provided effective support for the simulation and verification of future satellite networks.
