针对天地一体化信息网络规模庞大且技术多样,需要依托逼真的卫星网络场景来验证各类方案,提出一种云计算环境中卫星链路仿真方法。详细分析了影响卫星链路特性的关键因素,融合OpenStack和STK构建天地一体化信息网络仿真平台,通过对链路进行建模与计算,基于流表规则和队列管理规则动态实时切换卫星链路的间歇性、时延、误码率。为提高卫星链路的吞吐量,卫星节点具备动态路由学习能力,卫星链路可灵活构建与重构。实验结果表明,所提方法能够准确地对卫星链路进行仿真,有效保证卫星链路仿真的逼真性和周期性,有利于卫星网络场景的科学研究。
Aiming at the large scale and diverse technologies of the space-ground integration information network
it was necessary to rely on realistic satellite network scene to verify the various schemes.A method of satellite link emulation in cloud computing environment was proposed.The critical factors that affect the characteristics of satellite link were analyzed
OpenStack and STK were integrated to build an emulation platform for space-ground integration information network.Through the link modeling and calculation
the intermittence
delay and bit error rate of satellite link based on flow table rules and queue management rules can be toggled dynamically in real time.In order to improve the throughput of satellite link
satellite nodes have dynamic routing learning ability.Satellite links can be flexibly constructed and reconstructed.The experimental results show that the method can accurately emulate the satellite link
effectively guarantee the fidelity and periodicity of satellite link emulation
and facilitate the scientific research of satellite network scene.
